Background

I grew up as sports cars were just being introduced to the U.S.  There was a BMC (British Motor Cars) dealer in each town of any size selling the MG, Sprite, Austin-Healy, Jaguar, Rolls Royce, Bentley, Rover,or  Moris Minor etc. You could order a Morgan. With a last name of Clarke you can see that I have a leaning to British iron.

Vehicle Types

I'm writing this after watching a July 2008 TV show in Taiwan on Luxury items.  In the show they were confused about what the following types of items mean.  For example they classified a bicycle that can be folded up into a small package as a luxury item when in fact it's a utility item.  Maybe they were confused about what constitutes an elegant design.  Elegant has to do with the sparseness and/or visual aspects of a design and is different from Luxury.

Vehicles (and other things) can be categorized into Types based on their features.
Utility
Luxury
Performance
Economy
A Vehicle typically can be categorized in two or more of the above categories.  It's uncommon for a vehicle to be designed for just one of them.  But a pure type vehicle often is elegant whereas a vehicle that has elements of all four types may be a mis-mash design.  Note that there is some purpose for the vehicle that governs (restrains) the design.  For example utility trucks are designed for many different payloads and driving environments. 

Typically you need to sacrifice all the other types to optimize the one you really want.  For example a pure luxury car will not be economical, will not be very utilitarian and it's performance will not be as good a a sports car.

Reliability is a quality measure that can be imposed on all the above vehicle types.  The first Rolls Royce cars were designed with Reliability as the goal.  Because they were reliable when entered into a race they could finish where other cars broke down and did not finish.  Since Rolls Royce only built the chassis and a coach builder did the carriage they typically were luxurious.

Electric Cars

I feel that electric vehicles are being sold with the idea that electricity is "clean", i.e. there's no carbon footprint, which is just not at all the case.  The electricity needs to come from somewhere.  The existing electrical grid is designed with excess capacity so that a generation plant can be throttled up or down to match the current load.  This is not something that that solar PV or wind generators can do.

As every new electrical load, including car chargers, is connected to the electrical grid the grid's capacity is lowered.  We are now to the point that there are brown and black outs because the existing grid no longer has the head room needed for stability.

The cause of this is the lack of new generation plants.  Ideally they would be nuclear if lowering carbon emissions is a priority, but natural gas fired plants are much better than coal fired plants.  But as far as I can tell there are no new electrical generating plants being built while we are switching how energy is delivered to use more electricity than before.

Until there is a practical way to store energy at the grid level we will need classical electrical generation plants (coal, gas, nuclear) that can be throttled up and down for load leveling.

Europe v U.S.

While watching the YouTube: "Visiting Scholar Charles Falco on: "The Art and Science of the Motorcycle" I discovered why sports cars were developed in Europe while American cars are more like boats.
The U.S. has many roads that go in a straight line for hundreds of miles, but in Europe there are no straight roads. If you drive in Europe you need something that is good at making turns, not so much in the U.S.

Cycles, Motor, Bi and Tri

When in high school I rode a 3-speed bicycle.  It used what today is called an Internal Gear Hub.
Later I got a 165cc Harley-Davidson Hummer motorcycle (Wiki).  Maybe a Super 10?
The dealer was near my uncle's house in Salinas, CA.  The dealer, Larry Ketzel, was riding a dirt bike in the Nevada desert and was contaminated by an atomic bomb test, according to my uncle.  Around 1960 I crashed it dislocating my right shoulder and probably damaging my lower back.
Also had a BSA 500cc Gold Star single cylinder dirt motorcycle (Wiki).

I expect the Mk II Sprite and Smart car have questionable safety.  So it looks like the Mazda MX-5 is at the top of the list for a modern road worthy Light Weight Sports car.  Let me know if you know of a contender.
Genius & Stupidity - The Mini Story, 30:44 - (Wiki: Mini), 1959 - 2000 a UK product, 1975 British Leyland bankrupt, 1994/1995 BMW takes over the Mini. U.S. sales stopped in 1968 because of safety standards.  The 427 Cobra that I ordered to be a new 1967 model ended up being sold as a 1966 model because it did not meet California safety and smog standards which set the pace for the US.

Mk II Sprites  (1961 - 1964)

I had a red 1962 Mk II Sprite (Wiki) with the 948 cc engine that was my daily driver.  Bought it from San Jose BMC after the Palo Alto store salesmen would not talk to me (they were very snobby).  My brother liked this car so he bought a green 1964 Mk II (Wiki) and not long after that blew the engine or transmission (forget the details).  I sold my sprite to a friend and bought my brother's car.

Repaired the damage and also made major racing type modifications so that I could autocross on weekends. (Won some trophies) A measure of the handling was that you could drive through a freeway on/off ramp at double the posted speed without drifting.  The parts came from the San Francisco BMC dealer (Joe Huffaker Sr.) who was racing a number of BMC (Wiki) cars as well as building the Genie (RSC) two seat sports racing car similar to the Lotus two seat sports car.

The engine was brought up to Formula Ford specifications.  I could order parts from S.F. BMC in the morning and have them shipped via Greyhound bus to the Mountain View station and pick them up after work. Mag wheels with some positive offset to increase the track (which required cutting a lot of notches inside the wheel well lip and bending each tab up adding maybe 1/2" clearance between the tire and body sheet metal.  Larger tires were fitted to the Mag wheels.  A flange in front of the muffler allowed removing it and adding a straight pipe for a little more power and more sound.  The anti-Sway bar from a Simca (Wiki) was added to the front to stiffen it up for better cornering.

All the Sprites had "Ouija board" (Wiki) steering.  By that I mean that you pretty much just thought about where you want the car to go and magically that's where it goes.  The steering was very fast and light without any power assist because the car was light.  I would rank the 1964 Sprite, after the modifications, as the most fun car I've driven.

Also had a Mk 1 "Bug Eye" sprite which my brother painted orange, but it needed a new engine which I never got around to installing.  These were made between 1958 - 1961.

Mazda MX-5

As described in the paragraph on the Mk II Sprites, the MX-5 was designed to be like a sprite, i.e. very fun to drive.  It turns out that a number of fun to drive car kits are based on using an MX-5 as the donor car.

Tires

In the process of writing the computer program for analyzing the performance of the 427 Cobra I learned how tires work.  It's really simple, but not easy to find.  There is a "contact patch" on the ground where the tire flattens.  For example if you put carbon paper under the tire and lowered it onto the ground then lifted the tire up, you could measure the contact patch area.  If the tire pressure is multiplied by the patch area you get the weight on that tire.  Note that when air filled tires came out they were called balloon tires, not because of size, but rather because the sidewall has no weight carrying function.  It works in the same way a balloon would where the pressure in the tire holds the weight, not anything about it's construction.  The Wiki bicycle tire web page does not get this.  They also don't understand that inflation pressure times contact patch equals the weight on that tire.  So a skinny tire will need higher inflation pressure for a given weight.  This is why European derailer bikes with skinny tires require more inflation pressure than older American 3-speed bikes with fat tires.  Vehicles that are going to drive in mud, snow, sand &Etc. must have low ground loading (= Tire pressure) so use "fat" tires or tracks.

You can see that the tire must be sized such that at the inflation pressure there is enough contact patch to support the weight.  That's why tires that need to carry heavy loads are big.  In the case of trailer tires that need to be small, they have high inflation pressures to make up for their small size.

In the case of AA fuel dragsters and funny cars the tires start out "under inflated" so the rolling radius is shorter than it would be if the tire was inflated more.  As the car (and the tire) picks up speed the tire expands increasing its rolling radius and therefore acting as a variable transmission.  On these very fast cars the effect is quite pronounced.

There are two fundamentally different tread designs.  Tires for motorcycles and bicycles that lean in turns must have a tread that wraps around so that in a turn there's tread on the ground.  Early cars, for example those that used a parallel wishbone suspension, also leaned in turns and so had tires similar to a motorcycle.  But more modern cars (427 Cobra)  have suspensions where the outside tire stays pretty square to the road and so can make use of wide flat top treads.

The rolling resistance (Wiki) of a tire is a measure of how easy it is to push it.  It turns out that the larger in diameter a tire is the lower it's rolling resistance.  You can get a feel for that by seeing that when a small caster hits a piece of gravel it will stop, but when a large diameter bicycle tire hits the same piece of gravel it easily goes over it.  This is because of the mechanical advantage the the longer lever arm has.  Where, by lever arm, I mean the triangle formed by the center of the contact patch, the length along the ground to between that center and the gravel and the height of the gravel.

Coefficient of Friction of a tire (Wiki) relates to how well a tire grips the road.  Up into the late 1960s it was thought that the limit was 1.0, that's to say that a tire could only have a braking, cornering or acceleration that was limited to the weight on the tire.  Note that crawler tractors can have a drawbar pull (Wiki) that is far in excess of the tractor weight because there are cleats on the tracks that dig into the ground.  The exceptions are things like AA Fuel dragsters (Wiki) which use very soft rubber tires that "cog" into the pavement and then shear off the rubber.  The thing that allows the short 1/4 times is the Coefficient of Friction (>>1) that in turn allows acceleration higher than 1 G.  A street car that was an exception was a Corvette where each tire was different.  It could corner slightly above 1 G. (FastestLaps: 2005 C6 Corvette Z06, 1.06G)

One way to check tire inflation on a race car is to measure the temperature of the tread (Wiki) at the outside, center and inside of the tire.  These should be about the same.  If the center temperature is significantly higher than the inside and outside then the tire is over inflated.

But for most cars the limit is the weight on the wheel (1 G).  Tractor Pulling contests (Wiki) measure the drawbar pulling capacity of various vehicles with tires (not tracks). 

The Contact Patch (Wiki) area times the inflation pressure is nominally the load on that wheel.  But not exactly.  See: Truck Tire Types and Road Contact Pressures, by Pedro Yap (pdf), June 1989 for subtle variations and why they occur.

Tire Load Sensitivity

2019 July 11, While watching this YouTube: Mike on Bikes:  Motorcycle Traction EXPLAINED - says because of Tire Load Sensitivity (Wiki) - tires with lighter loading have more traction.  I have the book  "Formula 1 Technology" by the SAE on order.  Comments to the YouTube: Why Do Wider Tires Have More Grip? Tire Load Sensitivity - mentioned the book "Tune to Win" which also is on order.  The presenter does not understand balloon tire physics..  If the load increases the contact patch area must increase!
A possible explanation for this contradiction is that a contour plot of the pressure across the contact patch shows some variation, i.e. the product of area and pressure needs to be integrated over the patch area.  This might happen if the tread part of the tire was stiff while the sidewalls were very flexible.  An image might be a stiff cylinder (the tread) supported by an internal toroidal balloon.

If this is the explanation then Tire Load Sensitivity may depend on the construction of a specific tire and is not a universal property of all tires.
My gut feel about "Tire Load Sensitivity" is that there are special conditions that need to be understood.  That's to say I doubt it applies to all tires under all conditions.  For example the plot on the Wiki page for Tire Load Sensitivity came from Paradigm Shift Racing who's business is teaching drivers.  It's not clear where they got the curve or under what conditions it applies.  I have their book "The Perfect Corner: A Driver's Step-By-Step Guide to Finding Their Own Optimal Line Through the Physics of Racing" on order.

In the Master of Science thesis paper: "Estimation of vertical load on a tire from contact patch length and its use in vehicle stability control".  The contact patch length is measured to infer the contact patch area, hence the dynamic load on the tire.

Books

Tune to Win by Carroll Smith, 1978 - no index, no references.  I have the feeling that the book relates actual racing experience.  Says that as the load increases the patch size does not increase.  This book assumes modern wide racing tires with suspension that keeps them very close to square to the ground, not older motorcycle type tires on cars with a lot of body lean and parallel link suspensions.  Anti Dive and Anti Squat: pg 34.  Toe-In and Bump Steer: pg 62

Formula 1 Technology, Peter Wright (SAE), 2001, ISBN: 0-7680-0234-6 - Chapter 7 Tires:  Tire Load Sensitivity (pg 108). "The other characteristic of interest to the chassis engineer is the sensitivity of the tires to vertical load  However, in practice the peak load increases from very low loads and then falls again as the ratio of vertical load.  There is a limit to the loads that the tire will carry.  This characteristic is used by the chassis engineer to tune the cornering capability of each end of the car, by using the anti-roll bar to load up the outside tire on that axle and relieve the load on the outside tire of the other axle."

Speed Rating

When buying tires for the 427 Cobra where the top speed was around 155 MPH, the speed rating needed to be equal or greater than that number.  See Goodyear speed ratings where W, Y or Z rated tires are needed.

Schrader valve (Wiki)

Trivia question: What part of a bicycle/car has not changed since the late 1800s? answer: the Schrader Valve (Wiki).
The first patent by G. H. F. Schrader (473673 Apr 26, 1892) was for a valve that depended on the  pressure differential between the inflation side and the tire side, but this did not work well (see below) .  The next patent added a spring to keep the valve closed and depends on the inflation hose to have a prong to open the valve.

It turns out that these are a potential source of air leaks.  If you get new tires at Costco they replace the valve steams as policy.  Note for tubeless tires the valve steam is part of the wheel and may be as old as the car.  When inner tubes were common the valve steam got replaced whenever the tube was replaced.  So, in today's world the valve steams (and maybe the valve body) should be replaced when the tires are replaced.

483172 Valve for Pneumatic Tires, George H. F. Schrader, son of August Schrader (Wiki), Sep 27, 1892, 137/233; 137/550; 152/429 - uses spring.  This also allows a tire to be deflated by using the special cap in an inverted position.

Pressure Differential to Inflate Tire

A question that came up on the PIC list was what pressure on the input side would be required to open the valve.  A back of the envelope (BOTE) calculation by Denny E. is as follows:

Assumption - sealing surface 0.10" diameter
Pi * r^2 = 0.00785 in^2 area
Assumption - spring force = 1 lb force.

Pressure = force /area
1/0.00785 = 127 psi
Keep in mind that's plus whatever pressure is on the other side of the valve - which is further complicated because the area the seal contacts contributes to the closing force area, but does not contribute to the opening force area.

Speedometer & Odometer

Speedometer

The speedometer was invented by Arthur (Wiki) & Charles Warner.   After a decade of court battles Stewart & Clark Mfg Co and Warner Instrument Co merged in 1912 forming Stewart-Warner Co. (Made in Chicago Museum).  While Chicago Flexible Shaft holds 314 patents, none of them is for a speedometer/tachometer.

A tachometer and speedometer is the same thing.  The difference is what it's connected to.

Jones worked for American Graphophone Co around 1900, but it seems he became an inventor for hire shortly thereafter since he has patents in a number of very different areas.  Most inventors work in one area.  He may have been influenced by T.A. Edison who got a lot of publicity because of the large fortune he made on his patents related to Stock Tickets.












The similarity to a fly-ball governor is apparent.

GB191409958 same as this patent

This called a chronometric tachometer because it contains a clockwork mechanism that gets wound by the input shaft.  Note the dial reads RPM.  It is not a shaft turn counter.

Instruments come in metric and Imperial, this one has a "FEET" wheel rather than a "METER" wheel for linear speeds.

The outer dial is marked (0) to 100 [black type] and the small dial is marked 0 to 9.

The diameter of the "FEET" wheel is 1.175 so circumference is 3.691" = 0.3076'.
So if the shaft was turning at 10 RPM and the "FEET" wheel was used the inner dial would read 3 [red] for 3 ft/min.

So the "FEET" wheel should be 1.1459" dia, so that 3 Feet Per Minute lines up with 10 RPM.

On the small, thousands, dial 1 thousand RPM [black] lines up with 3 thousand FPM [red].

Operation
Input shaft at 9:00.
Top button is start.  Stop is automatic by clockwork.
button at 10:00 is reset.

To access the mechanism three 1.6mm (-) screws need to be removed.  Then the bezel can be removed using a spudger (Wiki).  But a special tool is needed to pull the two hands so I did not go further.

Description
Type A - 0 to 10,000 RPM
Type B - 0 to 1,000 RPM
Six second integration time, so pointer updates once each 6 seconds.
Input tips for: Centered shafts, uncentered shafts, wheel for linear speed.

Wipers

The first generation wipers starting int he a890s, were manually operated.  Then came the "automatic" wiper, 1920 - late 1950s, driven by a vacuum motor.  The problem with these was that when the engine is at idle the intake manifold has maximum vacuum i.e. the wiper works well when the car is stopped.  But when going fast the vacuum is weak and the wipers tended to stop working when you needed them the most. The next generation used electric motors and maybe had 2 or 3 speeds.
The next improvement was the intermittent wiper starting in 1967.
Today we have rain sensing wipers that only work when there's water on the windshield.

Power & Energy

Power

One of the key specifications for a car is the engine horsepower (Wiki).  Note the word "power" is in the name.  Picture a horse lifting something like a bale of hay up from a carriage to the loft of a barn.  Lifting 550 pounds one foot in one second requires one horsepower.

745.7 Watts is an electrical equivalent of 1 HP.

The amount of power a battery delivers is measured in Watts (Wiki) and is the Current times the Voltage across the load.  Light bulbs (Wiki) are rated in Watts.

The maximum amount of power a battery can deliver (P = V * I) depends on how much current it can supply without pulling the voltage down to the point where the power decreases.  Modern batteries have an advertised nominal voltage but the manufacturers typically do not talk about peak current or internal resistance.  When the 1-1/2 Volt No. 6 Dry Cell battery was common they were tested by using an ampere meter to measure Flash Amps.  A strong No. 6 battery might read 20 Amps.  If the voltage was 1 Volt that would be 20 Watts.

The current a battery can supply is determined by its internal resistance (Wiki).  Typically secondary (Wiki: rechargeable) batteries have lower internal resistance than primary (Wiki, non rechargeable) batteries. 

A common way of considering a battery is to think of it powering something for a day.  Twenty four hours rounds down to 20 Hours as the standard.
The current to charge (or discharge) a battery in 20 hours is called the "C" rate.  Where C is the capacity of the battery in Amp Hours.

Early rechargeable batteries used chargers that worked at less than 1 C.  Today's batteries come in different flavors some with lower "C" values are optimized to have more capacity (amp hours) while other batteries are optimized to support higher "C" rates.  If a battery is made using very thin metal foil for the electrodes there will be more space for the electrolyte, hence it will have more Amp Hour capacity than the same battery case where thicker metal foil is used.  The thicker foil will result in a lower resistance and a higher "C" rating.

The maximum discharge current is independent of the size or capacity of the battery and has a lot to do with how it's constructed. 2022-Jan-12 looking at the table of single Li-Ion cells (BatterySpace.com) shows the highest discharge rate for the Samsung INR18650-15M at 23 Amps while it has the lowest Ah capacity (1.5 AH) in the table.  The  battery with the highest AH capacity, LG INR18650MJ1 at 3.5 AH can only produce a 10 Amp discharge.  The 21700 size batteries have more capacity (up to 5 Ah) but lower currents (up to 15 Amps).

For things like an impact wrench power is what's required to tighten and remove nuts.  Since power is Volts * Amps you can double the power by using two battery packs connected either in series or parallel.  The connection really depends on what the motor is designed to take.  If a higher voltage battery pack is made using the same battery cells as a lower voltage pack then you will use more batteries in the higher voltage pack so it will be able to produce more power.  In the case of 18 Volt v. 40 Volt packs the higher voltage pack will have twice the power output of the lower voltage pack.

In the case of electric cars the battery pack voltage is in the hundreds of volts.

Energy

Some common units for energy (Wiki) are Joules (Wiki) (same as Watt Seconds), Watt Hour (3600 Joules), (electric meters measure kilo Watt Hours), Foot-pound (Wiki, 1.35 Joules). 
Note the scalar Foot-pound is an energy measure whereas the vector Foot-pound (Wiki) is a torque measure.

The energy stored in a capacitor, measured in Watt Seconds (same as Joules), is 0.5 * C(Farads) * V(Volts)2 This is how photo flash units are rated.

A common way to talk about battery capacity is in Amp Hour ratings (Wiki).  This is an easy way to compare the run time of batteries with similar chemistries and voltages.  But a much better way is to compare Watt Hours (Wiki) since you are including the battery voltage.  For example a tool battery rated 4AH and 18V has about half the energy of a battery rated 4AH and 40V.

Tool Batteries

There's a mystery relative to tool batteries like the Ryobi 18V line.  The standard and "High Performance" batteries are rated for the same 18V and 4AH capacity, yet tests show the HP battery performs better on Brushless tools than the standard battery.  Measurements show that both batteries have the same internal resistance.  So is this a marketing trick?  What's going on?  Let me know.

It would be possible to design a battery to get good results on the YouTube Torque Test Channel by making a battery pack with very low internal resistance at the expense of a small AH capacity.

Pete Brock-

 Low BMEP Engine

Brock Racing Enterprises

I went to a talk by Pete Brock at the Candy Store (Carol Shelby signed a photo of CSX3282 at a different Candy Store talk) because he was involved in the design of Cobra cars and in particular the Cobra Daytona Coupe.  A web search will find Pete in relation to Datsun, Pebble Beach and a company in Southern California designing cars.  He talked some about his background and some Cobra stuff but then the really good thing was about the new engine that he was building.  As he talked he pulled parts of the engine from a back pack and showed them to us.

Automobiles and most motorcycles got off to a bad start because government agencies taxed them based on the displacement of the engine.  I think this is still the case in Italy.  In many automotive racing classes the displacement of the engine is a major factor.  I know that the early Rolls Royce cars had names like Silver Ghost, Phantom and also numeric model numbers like 20/25 or 40/50.  This referred to the official Horse Power/Actual Horse Power.  The idea was you only paid taxes on 20 HP but you got 25 HP.  So car manufacturers and others have been locked into the idea of getting the most horse power per cubic inch.  This is a mistake.

When you look at airplanes with piston engines the most important factors are reliability and HP per pound of weight.  In the case of ships the important factor is HP per pound of fuel burned (Wiki: BSFC).  In both of these cases the engines are lightly stressed.  A technical way of saying this is that they have low Brake Mean Effective Pressure (Wiki: BMEP).  An engine with low BMEP does not turn at high RPM and does not produce a lot of HP per cubic inch of displacement.  Harley Davidson and BMW motorcycles have this type of engine today.  The very high performance motor cycles from Japan are an example of a high BMEP engine, very high red line for RPM, very high HP/Cubic inch.

Pete showed us the valve from a Ford 5.0 L V8 engine.  It looked like most automotive valves.  The thing is that at 5,000 RPM it takes 30+ (as far as I remember) HP to run the valve train.  That is because there needs to be valve springs strong enough to close the valve and the engine needs to compress these along with moving the mass of the rest of the valve train.  He showed us the valve from his engine, it looked like a #2 pencil lead with a quarter on the end.  Very much lighter that the Ford valve.  The spring looked a lot like what is used in a ball point pen!.  You could easily see that Pete's engine will not need a lot of power to run the valve train.

His engine is a V2 design with a capability of stacking to get a V4, V6, V8, etc.  There is a single size hex head bolt used for all fasteners.  A special Allen wrench with a long handle that acts as a torque limiter is the single tool needed to take apart and assemble the engine.  If more strength is needed then he used more of the same size bolts instead of a larger size.  Anyone who can work on a bicycle can work on this engine.

If the Ford V8 engine is removed from it's car and a V8 version of Pete's engine installed, the performance will be comparable because of the lighter weight of Pete's engine.

Pursuing this project cost Pete a lot and it was dormant for a number of years.  I talked to him a few days ago (Oct. 98) and it looks like the project may come alive again.

There are better ways to design cars and trucks if you can get rid of the old ideas.  Pete has some great ideas about utility vehicles for underdeveloped countries.  These would be easy to make and very practical to operate and fix.  One idea is to have all the wheels be non-steering and use differential engine control for steering, like on the Bob-Cat front loaders.

Wiki -BMEPBrake Specific Fuel Consumption (BSFC) - 114,800 bhp Sulzer_RTA96-C Container Ship Engine (data sheet showing BMEP & BSFC)

9103277 (Google, USPTO w/images) Moment-cancelling 4-stroke engine (MC4S), Daniel Sexton Gurney, Aug 11, 2015 - "Importantly, it should be noted that the peak BMEP for the MC4S system is more than 100% greater than most normally aspirated engines. This unexpected result points to a very powerful engine resulting from the improved air supply."
Interesting that this engine has a high peak BMEP yet also has good fuel efficiency.  But that's been my experience, i.e. if you drive with a light foot you get good gas mileage, but with a heavy foot you burn a lot of gas in exchange for high performance.  This engine has a sharp peak at 8,000 RPM and so will need a lot of gear selections or some type of variable transmission in order to stay at the peak.

Message to Dan Gurney at AAR Sep 10, 2015
Hi Dan:

I've just been reading your MC4S patent and it reminded me of a lecture given by Pete Brock at the Candy Store in Burlingame, California (a former car dealership, now a home for collector cars).  It was about his V-twin Low BMEP engine.  I think he said he had a patented connecting rod. 

Do you know what happened to that engine or where I might find more information about it?

Cobra Daytona Coupe (Wiki)

As part of the introduction of Peter Brock at the Candy Store some of his background slides were shown including the Daytona Coupe.
In one the two Netflix movies about LeMans, Ford and Ferrarri., "Shelby American" & "The 24 Hour War",a patent was mentioned that was a key part of the Daytona Coupe design.  This made the car controversial inside the Shelby group, but they built a car aimed at the upcoming Daytona race.  Also see the 427 Cobra chassis: CSX3282

To be fair the 1962 Ferrari 250 GTO (Wiki) has a very similar tail shape.

'69 Bentley

I got this car used in the mid nineteen seventies.  Used it cost about what a new top of the line Mercedes would have cost then.  I had this car over 20 years.  It turns out (in my humble opinion) that the Rolls Royce V-8 engine has a fatal flaw.  It is made from aluminum with steel cylinder liners.  The thickness of the block walls between cylinders is on the order of 1/8".  If the engine ever over heats the stress can cause the Al block to crack.  The engine is very likely to overheat because the o-rings that seal the liner to block joint are a rubber derivative and bio-degrade.  Also there are numerous water hoses that are made from rubber.  The water pump is designed so that a thin rubber part is both sealing the pump and holding the frictional torque of the rotating seal.  When the block cracks a new block is called for since the Al has been impregnated with plastic that makes welding impossible.  Needless to say, that a new block costs a lot of money. (2009 - IDEA - use J-B Weld epoxy to patch the cracks after grinding with Moto-Tool.)

'98 Intrigue

Intrigue Photo
This is my current everyday car.  It has very good handling (I drive in hills every day and going to San Francisco at freeway speeds in hilly country is easy).  This is pretty much a 4-door version of the Pontiac Trans Am (Wiki).

My Intrigue and all cars sold in the U.S. beginning with the 1996 year models have an On Board Diagnostic system called  OBD II..  On my car the connector falls to your right hand if you are the driver and feel at the lower edge of the instrument panel below the steering wheel.  The OBD II web page  by B&B Electronics  has information on what data can be read by their AT1 GM data link.  The AT2 data link for Ford is available, and the AT3 for Chrysler cars is coming.  Things like MPH, RPM, and a lot of emissions control information is available.  This is used by the technicians at the dealership to diagnose what caused the "check engine" light to come on.  Some road tests: Edmunds, Wheels, , Press Release, Auto Extra. I checked the NHTSA defects - recall page to see if there were any, none found.
ELM Electronics - sells an 8 pin PIC microcontroller that can be used to build you own OBD II interface

PS there are many OBD II readers on eBay now (2018) with BlueTooth, WiFi or USB interfaces.

Honda 2000 Odyssey EX van with Navi

This van has the ability to hold a few sheets of 4' x 8' plywood flat on the floor with the rear door closed.  This is possible because the second row seats can be completely removed in a matter of seconds and the third row seats fold down flush into the floor (the front seats have a notch on the back near the floor). It will also hold 10 foot 2x4s along the center line with the back door closed.

It also has the optional Satellite Navigation system.  The main electronics package is about the size of a VCR and is located under the passenger seat.  It contains a CONUS data base on a DVD disk. The GPS receiver is aided by a gyroscope (might be a misnomer, magnetic compass might be more correct?) and speedometer input.  When stopped the direction of travel stays correct.  The dash panel color touch screen LCD display needed the space used by the manual AC controls.  There is a button beside the display that brings up a virtual AC control panel.  This system has been customized by Honda for this application.

In addition of a map display there is a mode that will guide you to your destination, similar to the "never lost" system that's optional in Hertz rental cars.

I have gotten the latest DVD direct from Honda's web page (Order Nav System DVDs in drop down box) but have not really checked it out yet.  One thing I have noticed is that the recommended path from my house to the SF Bay Area has changed.  I used to take 101 South, cross the Richmond Bridge, 880 South and 237 West.  Now it says to take the Richmond Bridge then the Bay Bridge back to 101, the two bridges are to avoid going through San Francisco where there is no through freeway after the Freeways fell (Wiki) in the Loma Prieta Earthquake (Wiki).

There is also a built in wireless remote that can be programmed for conventional and rolling code garage door openers, and other features.
It uses the Homelink protocol.

It's been to the dealer for routine maintenance a few times and the bill is always $49.95 and they only did the routine stuff.

Key Fobs

The Wiki page for Car Key says "Mercedes-Benz uses a key that, rather than have a cut metal piece to start the car, uses an encoded infrared beam that communicates with the car's computer. If the codes match, the car can be started. These keys can be expensive to replace if lost and can cost up to US $400."  I think that's wrong since the key works to turn on/off the ignition when there are no batteries in it, so no power for the LED. It turns out that the ignition key function works without batteries because of a 125 kHz power signal from the car.

The key fob has a number of features.

Door Lock/Unlock

This along with the PANIC button and trunk unlock is accomplished using a Remote keyless system (Wiki) which in North America works at 315 Mhz.

                      Frequency Spectrum
The main carrier at 315 MHz and some modulation side lobes. (Agilent E4404B spectrum analyzer)

In addition the IR LED at the tip of the fob is also activated when any of the buttons are pressed.  This can be confirmed using a cell phone camera.  So both the RF and IR modes are used for Lock/Unlock.

Note that a small red LED at the upper left of the LOCK button blinks when any of the buttons are pressed to indicate a good battery.

Key & Immobilizer

The plastic key fob acts like a key even though it has no mechanical keying features.  The IR LED communicates with the car's computer to unlock the car

RFID is being used in place of the mechanical ignition key.

When the fob is inserted in the ignition the IR LED in the end of the fob works like an immobilizer (Wiki). 

Here is a still photo taken from the repair video that shows the RFID LF antenna coil.

My best guess as to what's in this photo:
The white rectangle at the far right is an IR device.
The coil is part of the RFID system that charges the yellow capacitor marked 476.  The ceramic cap just to the left of the coil causes it to resonate at the drive frequency (130 kHz or 13.56 MHz).
The RFID read back (key function) is based on using IR via fiber optic cable to armored box.

Maybe called the TA12 3-button MB key fob?
The large gold rectangle may be a ground coupling to the person holding the key.

Mechanical Key

There is a mechanical key inside the key fob that can be used to open the doors.  There is no way to use the mechanical key to start the car.  This is consistent with the immobilizer (Wiki) concept that prevents someone from hot wiring the car.  Note hot wiring is equivalent to turning the mechanical key.  This also means that if you cannot get a replacement key fob your car becomes worthless.

It turns out the new key fob is not compatible with my old mechanical key so a new mechanical key needs to be cut to go with it.

Replacing Key Fob Batteries

Note
If battery fails the Lock/Unlock function will not work.
BUT . . . the key will still work the ignition switch.
Use the Red LED on the button side to
see if the battery is good.
To replace the key fob batteries:
Get two each CR2025 3 Volt coin cell batteries.
Using CR2032 batteries will NOT work, they are too thick.

Remove the mechanical key by sliding the gray button.

Use the mechanical key to press the gray plastic latch (see photo)

Slide out the top (positive side showing, see photo) battery.
Note the other side looks similar but there you will not see the (+) symbol.
Slide out the bottom battery through the top side.

Install the two CR2025 batteries (+) side up (see photo).

Note: by attaching a store customer ID tag to the key,
if it's lost I might find it at the store because someone
turned it in.  This solves the problem of putting your
address or phone number on the keys.

Note2:  The fob was not locking the car, but it was working
for starting and driving.  The batteries tested low, but in the
green.  If I would have waited longer the key may not have
worked to start the car.
Mercedes-Benz C230 Replacing Key Fob
                      Batteries

Key Fob does not lock/unlock

At first this looked like a dead battery issue, but the batteries test good (ZTS MBT-1).

My spare key fob did not work, but the batteries tested dead, moved good batteries from other fob.
Note when LOCK or UNLOCK is pressed and held down a red LED blinks once which would seem to indicate good batteries.
Also when the small end of the fob is pointed at a cell phone (front is more convenient) camera you can see the IR LED light up.
The spare fob is now working, so the every day fob needs to be replaced.

Note this old fob does allow starting the engine and driving the car so still is a valuable thing to keep.  Note that there are no batteries in the fob, yet it still allows starting and driving.

Key Fob Styles

When the technician came by to synchronize the new replacement key he found that my old mechanical key would not fit into the new fob.
It turns out there are at least two styles of 4 button (Panic, Lock, Unlock & Trunk) fob.  The solution was to have a new mechanical key cut for about $35.
My existing key has a number engraved on the left side near the tip:  221 4045.  This may be style 4B?

Fig 9 It turns out that I was using the valet key instead of the owner's key for a couple of decades.  Note that the left valet key fob case has 3 buttons, panic, lock & unlock.  The location where the trunk unlock button should is hard plastic.  BUT . .  .
the PCB does have 4 buttons.  The owner's key (to the right of the valet key) does show the trunk unlock icon.  The new factory replacement key only has 3-buttons, omitting the trunk unlock function, which is correct since I asked for a replacement of the key I was using, not knowing at that time I had asked for a replacement valet key.

PS Dealer's often put the valet key in the pouch with the owner's manual.  It should be taken from there and put somewhere other than in the car to lower car theft rates.

Cell Phone

2023 May:  Update.  There is some variability in how well a cell phone connects to the car's Blu-tooth.  My current LG G6 used to be very good at connecting, but for the past couple of months it takes a power cycle to get it to connect.  Why? Let me know.

Dec 2012 Looking into adding a cell phone.

How-to Guide For Cell Phone Upgrades, Plug-in And Bluetooth - the car should be pre-wired, i.e. the steering wheel has the buttons and the display has a phone page in the menu.

Note: The factory cell phone setup back in 2003 was to have a Motorola V60 analog cell phone (Wiki) hardwired to the car for control and for an external antenna.  But today (2013) Motorola no longer makes cell phones with a provision for an external antenna and the remote control needed for answering and making calls is handled on a wireless Bluetooth link.  So the upgrade path is to install the Phone Support Electronics (PSE) module into the D2B (fiber optic) loop and use a short RJ-45 cable to the Motorola Bluetooth dongle in the top (shallow) center console compartment.  No RF coax parts are involved in the upgrade.

After removing 3 No. 2 Philips screws from
 the bottom of the top compartment and closing it,
then opening the small top compartment,
the false bottom of the top compartment can be lifted and flipped over.

You can see the coax antenna cable and RJ-45 socket.

Note:

If others are riding in the car they can enable their Bluetooth and sync to the car by entering the PIN number for the Motorola Dongle.  But probably only one cell phone at a time since their directory will be loaded into the car's directory.


The order of the fiber optic loop is important.  This will be used for Bluetooth control of my Motorola Electrify 2 cell phone.
If a component is missing then it's removed from the list but the order of connected components must be maintained.
It should be:
  1. Radio (D2B (Domestic Digital Bus, so really should be D2B)  (Master) <installed>
  2. Component No. 1 (Bose Sound System) <not installed> - got poor reviews.
  3. Component No. 2 (Voice Control) (SBS) <not installed> - not sure what it's capabilities are
  4. Component No. 3 (Phone) <PSE module to be installed in trunk> - this is what I'm adding.
  5. Component No. 4 (Tele Aid - COMMAND) <not installed> - not clear what it does
  6. Component No. 5 (CD Changer) - car came with the 6 CD changer installed in glove box-
  7. Back to Radio (Master) <installed>

Voice Recognition Kit

The problem is the control stalk.  It needs to be pulled back to activate the microphone and voice recognition system, or pushed forward to cancel.  These are only available when ordered with the switch assembly and cost a small fortune.  The stalk can NOT be purchased as a stand alone part!

                  Mercedes-Benz Voice Recognition Kit for C230
Although this voice control stalk has the correct appearance for a late 2003 C230 coupe, it does not have the correct end to mate with the socket on the right of the steering column.
The black plug that was removed from the column socket is about 0.221" (5.61mm) O.D. and that's close to the O.D. of the stalk the tip on this stalk does not have the notch that the correct stalk has.  So this stalk needs to be modified.

The correct PTT Lever may be Q 682 0837

2003 Mercedes-Benz Voice Recognition Kit for
                C230

The OD of a 1/4" brass rod was ground down to 0.240"
which allows a snug fit into the steering column socket
for the voice PTT switch stalk.

A slot approximately 0.030" wide was cut into the end
to clear the pin at the bottom of the socket.

Then the edges were filed away so that the rod can be
turned about 22.5 deg CCW.

Then a recess was added allowing the rod to be locked
in place by the spring pushing it back against the pin.

                  Mercedes-Benz Voice Recognition Kit for C230


The small and medium diameter parts of the stalk have been
cut off (Mini Cutoff Saw).

The OD of the exposed brass was ground down to about 0.24" dia.
using a Drill Press.

A couple of holes 0.0625" diameter were drilled using the Spin Indexing Jig
about 22 deg apart.  The drill bit was used as a mill to connect the holes.
PS something went wrong and this did not work)
The 1/4" brass rod has been working no problem....
until October 2021 when the fingers broke.
I have a length of 6mm steel rod to make another stalk.

The Voice Control box mounted in the trunk under the trunk forward cover plate.

Note the label is facing down and the box is held by clips.


27 Jan 2013 - Installed the box and changed a D2B cable in the right rear of the trunk and another D2B cable in the passenger side console.  Now the fiber optic loop is:
Radio -> Voice Control -> Phone -> CD Changer -> Radio.
Note: If the radio or CD are playing and the loop in opened the sound will stop.  It restarts a couple of seconds after the loop is reestablished.
Note:  The voice control PTT stalk is a momentary switch, i.e. you pull it back and release.  Then the radio beeps and it's ready to accept a command.
           If there is sound (radio, CD, Tape, etc.) then the voice control is not listening, so you need to pull back again for a new command.  I.e. when a command finishes the voice control is turned off.
           Pressing the PTT stalk forward cancels the current command.

2021 - The brass stalk I made has broken.  The next one needs to be made of steel.  PS I've also learned that the stalk can only be purchased along with the "watch spring" switch assembly and that costs a small fortune as does the R&R it get in working.

ODBII

When GPS first came out users on boats wanted a standardized interface so the National Marine Electronics Association (Wiki: NMEA) came out with their specification 0183 (Wiki).

GPS receivers also have a manufacturer specific binary interface, for example the Motorola AtAt command table.  There's a different command structure for Trimble and for Rockwell (PLGR, DAGR).

I think there is a similar situation here.  All car makers support a common interface, OBD II (Wiki).  There are many Parameter IDs (Wiki: OBD-II PIDs).

The Data Link Connector (Wiki: DLC) is standardized (Wiki: OBD).  It supports three buss protocols: SAE J1850, CAN & K-Line/L-Line.

In addition each manufacturer has their own maker specific interface.

ODBII First Try (Didn't work) to Bluetooth

Hardware

On Board Diagnostic II (Wiki) is the connector that's within reach of the driver.  In the past (prior to maybe 2012) the cost of an OBD reader has been in the hundreds of dollars, but now there are units available with Bluetooth connectivity to work with smart cell phones for very reasonable prices (under $20) like the ELM327 that reads not only US cars but also most foreign cars as well.  It's called a generic OBDII Bluetooth adapter.

The eBay ad "ELM327 OBDII OBD2 V1.4 Auto Car Bluetooth Diagnostic US" lists cars that will work with this adapter:
Benz 2001/02/03 W203 C200K (ISO)

OBDII ELM327
The pin numbering is backwards from that shown
on the Wiki web page for OBD.  But the LEDs
light and sequence so at least the power supply
pins are correct.

  Unfortunately when plugged in the LEDs are facing the pedals so it will take a small mirror to see them.

Pairing

 LEM327 and Android phone (Motorola Electrify 2) requires:
Searching for Devices under Bluetooth in the phone, then
select CHX (which is how the ELM327 shows up on my phone) and enter the pairing pass code 6789 (not 0000 or 1234).
Now CHX shows up with a gear wheel, i.e. it's Bluetooth paired.

Connecting

This is my current problem.  When the free version of Torque is started it says:
OBD Device not found, retrying. . . .  Connecting to OBD via bluetooth . . .

and (after adding it) the Current Drive Cycle Status window shows:
Waiting for OBD Connection....

I've gone into the (three vertical dots settings in the bottom right) and selected connect to CHX (not the car's Bluetooth) and selected Disable ELM327 auto timing adjustment, the port number of 35000 is the default.

Test on Olds Intrigue - 2 March 2013

When plugged into an Oldsmobile Intrigue the LEDs are facing up and visible.  They light in sequence front to back to front and stop with the front red LED on solid.  But although the Motorola Electrify 2 cell phone is paired to the CHX Bluetooth device, the Torque program fails to make a connection.  The same problem as with the 2003 Mercedes-Benz C230.  Maybe this particular device is defective?

OBDII Software

Torque - The problem is that there's no manual or way to get support other than via a blog on their web page.  The type size is so small I can't read it.
Questions:

1) where's the user's manual?
2) how to delete a dial?
3) how to move a dial that's positioned so half of it is off the display to the center.
4) the free "Lite" version automatically came up with a Boost gauge, but that's not an option on the full up version.  How to get it?
5) how to use the 1/4 mile icons?
6) how to use the Map Display icon?
7) How to start the Track Recorder Plug-in?

When help is pressed it opens a browser window to their web page.

Here's a YouTube video showing the Track Recorder plug-in.  http://www.youtube.com/watch?v=GHLchcKpa9g
The same author has other Torque related demo videos.  But not how to for beginners.

2023: In the past I've tried some OBDII Bluetooth adapters, but was not at all happy with them.  I also bought "Torque" but when that cell phone died it was gone.  After seeing a YouTube promoting a modern OBDII reader I looked around and found the Autel brand and the AL629 model that supports Mercedes Benz and many other car brands.  On order Christmas 2023.

The connector and pin assignments are in SAE J1962. 
Note that OBD_II has provision for different bus types including: SAE J1850 (pins 2 & 6) Chryusler/GM/Ford; CAN (pins 6 & 14) and K-line (1-wire)/L-line (2-wire) (pins 7 & 15) ISO 9141-2.pdf; CARB (Wiki).  Pins left to the manufacturer: 1, 3, 8, 9, 11, 12, 13.

This is a tool with a screen and buttons rather than just an OBDII to Bluetooth adapter.

Software Update
Ended up phoning the factory since the on line registration did not work. A very helpful lady walked me through the process of installing Maxi PC Suite.
Then updating the MicroSD card from the AL629.  It turns out there were only about a dozen updates needed.
There is a manual icon on Maxi PC Suite that leads to their support web page and one of them is for the AL629.
When you see the list of possible updates at the bottom of the list is "Select all".
Operation

There are no internal batteries.  It powers up when connected to either a Data Link Connector (Wiki) or a power source using the Mini USB cable.

Auto Door Lock chattering

When the car gets to about 10 MPH the doors automatically lock.  But now the drivers door chatters.
The remote key fob will lock the door.
There was a post with the very same problem.  Too much hassle, I just let it chatter.

I have a C180 Kompressor 2003 model, and the passenger front door lock was jumping up and down several times with a machine gun effect when locking or unlocking and sometimes didn't lock or unlock properly, all the other doors were OK, I contacted MB and they told me I needed a new door locking mechanism, £68 and £180 to fit it. So I purchased the lock and decided to fit it myself, It was quite a simple job, took one and a half hours altogether. as this seems to be a common problem I can now explain how I did it for those who wish to try it themselves:

You will need: Set of Spline screwdrivers, Flat screwdriver, Pop rivet gun, 3 small cable ties, Drill and 5 pop rivets.

1. Pull off the tweeter cover on top of door panel near front of window, no need to disconnect wire, just let it hang down.
2. Pull off SRS badge and remove the spline screw behind it.
3. remove the door latch plastic cover (1 screw)
4. At the bottom of the door pull handle next to the armrest there is an oblong slot, insert a flat screwdriver and prise the top half off, it is just clipped in. there are 2 spline screws behind it, remove them.
5. Using a plastic wedge of some sort or just by hand and starting at the lower part of the door latch, prise off the lower half of the door panel there are 6 or 7 plastic clips which hold it on, (I did this by hand and without breaking any but it may be worth purchasing a few just in case)
6. Lower the window and while pulling the panel slightly towards you, use your other hand to pull the panel upwards from the top starting at the front end, (this is quite tight, but it will come up)
7. panel is now off, pull the plug from the window switch and disconnect the cable from the door handle by opening the handle slightly and pulling up on the hook, the cable can then be removed from the door panel insert.
8. Drill out the 3 pop rivets holding the air bag and the 2 pop rivets holding the lower window strut. do not disconnect the airbag, let it hang down or tie it out of the way.
9. Remove the 3 screws holding the door latch and disconnect the wire from the panel near the front of the door. ( I actually cut the wire and pulled it through the loops to keep the original cable ties in place, when I replaced it I just used new cable ties to attach it back to the original location.)
10. You can now remove the locking mechanism by pulling it down and then towards the front by pushing back on the window strut.
Now do everything in reverse.

Passenger Side Mirror & Turn Signal Lamp

This assembly is designed to fold back, like when hitting the garage wall when driving into the garage, BUT it was not designed to fold forward, like when backing out of the garage.
The newer model cars have electrically operated mirror assemblies that fold in to make the car narrower.  I wonder if they can be retrofitted to my car?  Let me know.

The Mirror Wire holds the mirror backing plate.
Pushing in on the end or lifting the center allows the
mirror and it's backing plate to be removed.
There are two quick-fit wires that need to be unplugged.

The socket that mates to the plug on the mirror cover-turn
signal lamp assembly is just on it's cable.

The "Clip" is what holds the lamp assembly to the frame.

New mirror installed - not yet done.

When backing out of garage the wall moved in front of the mirror, breaking the glass (but no pieces fell out) and causing a malfunction notice saying the lamp was out.
When the turn signal was on to the right, inside the car it blinked fast, but outside the front and rear lights blinked at the normal rate.
Pressing the reset button (like used to reset the trip odometer) turned off the malfunction notice.

After removing the mirror cover-turn signal lamp assembly from the car and testing the lamp by sticking a couple of bare wires into the socket and checking the resistance (2.8 Ohms) it was determined that the lamp is OK.  The problem was that it had been unplugged.  It was not obvious where the socket should be attached to the mirror frame, so I just plugged it in by hand and reinstalled the mirror cover-turn signal lamp assembly until it snapped into place.

I have a replacement mirror glass on order.

Battery & Alternator

Starting late Nov. 2015 the starter motor was slower and slower.  I have an appointment for service, but the soonest was early next, so 9 Dec 2015 took to local dealer to have battery replaced, but they found that the alternator was weak which was part of the problem (the battery was 12 years old).  Data on the battery for this Mercedes Benz C-Class 2 door coupe model C230 Kompressor:

         Part # 49EXTJ
The rest of the story.  There was a problem with the electrical system (forget details) so took car to the Santa Rosa MB dealer.  They charged me for the diagnoses that the generator was bad, but would not work on it since it was not a MB part.  My local dealer did replace the generator no charge.

Window Auto-Up Not Working

After replacing the battery and alternator a new problem has shown up in that the windows no longer automatically go up. 
At this time not sure if this is a problem that's easy to fix using a factory computer interface to reset the auto up or if it's related to damage of some component.
Solution:
Raise the window by holding the button up on the "first setting", i.e. don't lift it all the way up.
Once it's closed, then lift it all the way up and hold it there for 10 seconds.
Then try again, auto down and then auto up.

This fixed it for me.

Flat Tire

2021 Nov 24 - left front tire failed with plenty of tread.  I was told that tires have a life time after which they can no longer hold air?

The Tire

The load Index (Wiki) in the door jamb is 91 but the actual tires are 89 so rated for less weight, the wrong tire.
The Speed Rating (Wiki) is H (130 MPH) or V (150) on the door jamb, but the tires are T (118 MPH), so again under the rating.

2021 Nov 26 - have 4 tires on order and went to drive the Honda Van but it's battery is dead, so now have on order the GB150.

The Spare

It was smaller in diameter and thickness prior to inflating.

C230 Flat Tire

Replace Valve Steams

When Costco deflated the spare tire they threw away the valve steam.  I later learned that's because these are a source of leaking and so replacing all of them with new units was policy.  The valve steams in the front wheels may very well have been why those tires were loosing air. 

Mileage on the odometer was 57,880 after the tire change.

Cell Phone ID

If your cell phone is on another person's account they can change the Caller ID (Wiki) but the cell companies refer to that as: Share Name ID.  The account holder can change the Share Name ID on a phone by phone basis.

NOCO GB150 Jump Starter- GB150_User Guide.pdf

Was the Flashlight used by the flat tire pickup truck operator, not really a AAA  tow truck.  It is also a battery jumper.
Got this to jump start the Honda Van.
Note: When jumping a vehicle battery wait a while after connecting the two batteries for some charge to move into the dead battery.  That way you get more starting current.

This contains 3 series connected pouch type Li-Ion cells.  Rating for the series string: 12 Volts, 88 Watt-hours, 7.3 Amp hours.  These cells are rated to deliver 3,000 Amps hence the low Ah capacity.

The GB150 has some advantages over the newer GBX155. Sometimes "New" isn't always "better"! My Old NOCO GB150 jump box vs My New GBX155 jump box, 15:46 - the GB150 has a built-in voltmeter and the GBX155 does not.
The new GB150 is rated 12V 3000A. The old Genius Boost Pro GB150 was rated 12V 4000A. It also was marked "22500 joules 3S"
The GBX155 turns off after 60 seconds, but the GB150 stays on for until it runs out of power, i.e. many minutes so can be used as a battery.

The Boost Max GB250+ $1200) is rated 12V 5250A and the GB500+ ($2000) is rated 12 or 24 V, 6250 A.  They both have the digital voltmeter and the both have the 60 second timer.  They come with the XGC4 56 Watt 12 Volt charger that's compatible with the: GB70, GB150, GB250+, GB251+ and GB500+.  Note the U65 USB-C Power Delivery charger is rated 65 Watts (3.25A @ 20V) so offers faster charging on the GBX45, GBX55, GBX75 and GBX155.

New Product Idea

The GB150 is a first generation USB device (Wiki).  Newer USB devices only use the USB-C connector for both charge and discharge because of EU law.  And the latest USB devices have Power Delivery (Wiki) options, which when paired with the 3 or 5 Amp current limit results in up to 48V @ 5 Amps (if the GB150 was newer) or 240 Watts.  That's to say a USB-C version could charge faster on the USB port than on the 12V port.  It would also make an excellent high power USB-C power source.

update 2023 Dec: 20230163540 Fast charging universal serial bus (USB type-C PD Ver 3 - up to 60 Watts) connector and battery charging system for an auto battery charger, Derek Michael Underhill, Ifechukwude Christian Iwerunmor, Tom Situ, James P. McBRIDE, James Richard Stanfield, Noco Co, 2023-05-25, -  they seem to have this idea already.  They also have an output that fully supports the same voltages as the input.  Note the output makes sense only on devices like the jump starters that have a massive internal battery.

The Boost X series (GBX model numbers: GBX45, GBX55, GBX75 & GBX155) is similar to the Boost series (GB model numbers) except the GBX models have USB-C PD input & output ports that can accept/deliver up to 60 Watts (nowhere near the 240 Watts that's possible, but a huge improvement on the typical 5 Watt charger).
These are 4S unlike the GB series which uses a 3S battery.
GBX55 Data Sheet:
USB-C (Into GBX): 5V@1.5A, 9V@3A, 12V@3A, 15V@, 20V@3A
USB-C (Out): 5V@3A, 9V@3A, 12V@3A, 15V@3A, 20V@3A

The GBX requires a USB-C PD device to charge it and Noco offers the U65 Universal AC (120/240 VAC 50/60 Hz) 65 Watt power supply which comes with AC plugs for North America, UK, EU, and AU.  Output: DC 3A/5V 3A/9V 3A/12V 3A/15V 3.25A/20V - 65W Max
GBX Update There are a number of YouTube videos saying there's a problem with the GBX units not taking a charge.  This happens if the GBX battery voltage gets to low then you can not charge it.  A fix is to use a USB-A to clip lead adapter.
YouTube: No-Open NOCO Repair: Power Measurement and Charging Hack, 9:01 - @3:26:  The USB-C Ground has a direct connection to the GBX battery ground.  The positive (red) battery clamp is a direct connection to the GBX positive battery terminal.

Noco Genius 10 Battery Charger - Maintainer

I like the Noco GB150 and when I found out that they also made a battery charger I looked at a number of different models.
They make 1, 2, 5 and 10 Amp chargers and also have models for multiple batteries and models for direct connection to the battery, and industrial chargers for 24, 36 & 48 Volt batteries.
The highest current single stand alone charger is the Genius 10.

Also got the GC040 Carry case for the G10 charger.

When these photos were taken the 12V flooded lead acid LED is illuminated (the one closest to the button).  But the next time I looked at it the 12V AGM LED was on, i.e. it figured out that this battery is an AGM type.

Foxwell BT-705 Battery Load Tester

The BT-705 has no internal battery.  But once you make menu selections, they show up the next time the meter is used.  Maybe a super capacitor or EEPROM memory?
PS While is have Wi-Fi connected printers, I don't have a blue-tooth printer so was not able to test the printout.

The battery Cold Cranking Amp (CCA) specification can be entered (maybe in steps of 5) between 100 and 2000.

Foxwell BT-705 Battery Load Tester

Prior art battery load testers used a DC load, i.e. a big bulky resistor as a load.  While these worked they also sucked a lot of charge out of the battery.  The newer method of patent 3909708 measures the internal resistance of the battery which has no effect on it's state of charge.
I think that, based on size and weight, the BT-705 uses a DC load for CCA and measures internal resistance as a separate test.

3909708 Electronic battery testing device, Keith S Champlin, 1975-09-30, - uses AC test signal and op amps to determine resistance of battery and computes current (CCA) and power that can be delivered.  To pass a battery needs to deliver at least 75% of it's rating after correcting for temperature.  Cited by 182 patents -

Amp Hound 2

A way to figure out which circuit has a parasitic current draw which causes the battery to go dead.

Amp Hound 2


The problem with this method is that it only works for constant loads.  For an example of an intermittent load see:
Which Parasitic Draw Test Method is REALLY the Best?, 38:08 - He likes putting a DMM in current mode with Min-Max activated, in series with the battery.  Ford, and maybe other makers, have a specification requiring less than 50 mA total draw on the battery.  That way, after a month of being asleep, the car will still start.  The recommended method is to use a DC clamp on ammeter to know when the current draw is happening, then use a DMM to find the circuit.

This is a cleaver idea.  A small hand held instrument that knows the resistance of common automotive blade type fuses (Wiki) in sizes Maxi, Standard or Mini/Micro.  A sensitive DC voltmeter has it's reading multiplied by the fuse resistance and so the display is the current going through that fuse.  This allows monitoring the current in that circuit and also finding phantom loads.  That's to say there should be no current in a circuit that's turned off, so if you find current there's something drawing power.  For example a car that has LoJack (Wiki) installed by a dealer in their favorite secret hiding place will draw power from some circuit, but it will not be known to a new owner, who just sees the battery going dead much faster than it should.

8384554 Audible current monitoring device, Kevin M. Curtis, K M C Electronics,2013-02-26, - Amp Hound 1?  replaces fuse with known shunt.  It makes sense that can be eliminated by storing the resistance of common fuses and asking the user to input the fuse parameters.  Even better would be to measure the actual fuse in situ.  Maybe that will be the AH3?

CD Player Error Message

When trying to play a CD an error message appeared on the audio device display.  The next time the car was at the MB dealer for service I asked about fixing the CD player and they wanted over $1,000 just to figure out what was wrong.

When preparing to send the car for the next scheduled service I was cleaning out the glove box and saw the CD player and the thought occurred to just open and close the door to the player to see if it would reset.  It did reset and now the CD player is working.

Rear Lights

2023 April: Driver's side brake light burned out.  Red warning on drivers display.  On older cars the lamp would be replaced by using a screw driver to remove the plastic lens, but on more modern cars the lamps are replaced by removing sockets from the back of the lamp location.  The trick is to use needle nose pliers to pull the tab at the very top of the assembly after pinching and pulling out the bottom a little.
The top lamp is for brakes and is marked GE 1057, 392, Hungary, 12V P21W (Power: 21 Watts, i.e. 1.75 amps), E1 2DX
The top 3 lamps are all the same GE 1057.
The bottom lamp is a dual filament GE 1157.

911 Carrera (Wiki)

Problem of rough running near idle and mid-range.  This is the Bosch Motronic (Wiki) Mass Air Flow Sensor.  This system was used in a number of German cars like the Porsche, BMW &Etc.  A spring loaded vane is pulled open by the air stream and that turns a special pot on a ceramic board.
Instead of a normal pot this one has a laser trimmed resistor network feeding in correction voltages.  So "12 Volts" needs to be applied and the voltage on the wiper measured.  The problem is that the resistive material on the board wears away and then the dual wiper contacts make intermittent contact resulting in rough running at some mass flow rates.  By slowly turning the pot arm and measuring the voltage on a DMM, you will notice "OL" flashing when the dual wiper contacts are not making connection.  Note the OL indication was caused by ranging, not OverLoad, so locking the range when 12 Volts is applied stops the OL indication.

It may be that there are two Porsche part numbers for this:  Let me know.

This is the only one to have, accept no substitutes, and do without until you can get one.  I have seen up to 4 CHP radar traps all lined up in a row (the counter tells you how many bogies.  The Forward, Back or Side indication is really cool.  I have seen traps off to the side because I know when to look, otherwise they would never be seen.  For approaching cars with moving radar you get a lot of warning as well as knowing that they are in front of you (of course it also could be a car parked on the shoulder behind tall grass).  On a few occasions I have picked up the local oscillator of a cheap detector in a nearby car and can tell which car it is in.

The optical sensor for laser speed guns goes off when passing some electronic signs.  The warning display and sounds are different for the different types of radars so you know which is which.  Even though I can't tell you the sound or display for each type, I do know the sound of a highway patrol radar and it's different from the other sounds.

Hummer by A. M. General

One day while driving down the 101 freeway going South to Santa Barbara I passed a very long column of HMMWVs being delivered to the army at Hunter Liggett (Wiki). There were all kinds of models, most fitted with military radios. I started to study them at that time. It turns out that A.M General would not sell me a Hummer at that time because they were not street legal and they had their hands full building them for the Army and other U.S. and foreign services. Later they developed the "Heavy Hummer" that had a Gross Vehicle Weight (GVW) in excess of 10,000 pounds. This required not only adding heavier springs for the vertical load but also a lot of changes to the drive line to handle the higher torque that propelling the heavier vehicle required. With this higher GVW the rules change for street licensing and made the Hummer street legal. A friend purchased one of the first 100 and had it custom painted a civilian camo (the factory could not use the same robot pattern they used for the Army for legal reasons). My friend ended selling his back to A.M. General because of all the problems it had. One of the problems was that there was nowhere he could go that had trained mechanics. If the mechanic is not trained on the Hummer in the process of fixing one problem, he can create one or more new problems.

The Mercedes G-wagon (Wiki) is a very expensive civilian vehicle that is attempting to emulate the HMMWV.  This is the vehicle the rich bad guys drive in movies.

Lamborghini made a similar vehicle the LM002 (Wiki) based on an off shore boat engine produced in 1984 it weighed 3100kg had a v12,dohc,4v/cyl. 455hp,369lbft,tranie 2x5m ,0-60 in 7.9 ,top speed of 120 ,also it was 4wd front-engine.  But, like the G-wagen, is only a pretender to the HMMWV.

Harley Davidson Hummer

This was my first motor vehicle after I got a drivers license in the 1950s.  My uncle lived in Salinas, CA (Wiki) and there was a Harley dealer near him so we purchased from Larry Ketzel's dealership.  Larry was riding in Nevada when an atomic bomb was tested and the fallout caused him medical problems (Wiki).

I got the 165cc two stroke Hummer model (Wiki) and drove it for a number of years.

One day when making a right turn where there was a gas station on the corner, I maybe hit some oil and the next thing I knew the pavement was rapidly approaching my face.  So I put out my right arm.  But that caused the shoulder to dislocate.  Every now and then it would pop out and then my arm would just dangle, i.e. I had no control of the arm.  I learned to bend over and let my right hand drag on the ground then gently step on my right hand, and gently move to stand up.  This would pop the shoulder back in place.  But once while at home, I was doing a lot of traveling for work, it popped out when I was in bed.  I would have been trapped if in a hotel on the road, but at home my wife helped me recover.  That led to a surgery to prevent further problems.

What Goes Wrong

Production Volume v Reliability

Reading the Hummer Forum,  my friends experience and my experiences lead me to believe that when you have a car that is made in relativity small numbers, you are going to have trouble in general and also in getting service.  In my friends case the mechanic would make new problems as he tried to fix existing problems.  This same thing happened to me with an '86 Turbo Inter-cooled 745 Volvo wagon. The block had a bad freeze (casting) plug, so the dealer, under warranty, replaced the raw block because the model was so new there were no short blocks available.  In the process he cross threaded the plastic radiator, causing me grief on a trip to Santa Barbara.  Some cars like the Corvette ZR-1 have a V-10 engine so complex that the local dealer is not allowed to work on it, instead it is sent to the factory for repairs.

Cars like the Honda Civic (Wiki) or Ford Taurus (Wiki) that are made in very large numbers tend to have the bugs worked out.

Rubber Biodegrades

Rubber parts cause a lot of problems.  Rubber and the synthetic version of it all biodegrade in air or water.  Any rubber hose or gasket is a problem waiting to happen.  If rubber is used as part of the insulation on wires they will get hard, crack and short out...it's just a matter of time.  The '29 & '34 Rolls Royce cars have no rubber parts except for the tires.  The wires have a cloth woven over the insulation (don't know if it's rubber or something else?). There is a metal tube between the 1929 RR frame and engine that carries the fuel.  It has a few turns about 3 inches in diameter to allow for flexing.  Rubber parts failing was a huge problem on the '69 Bentley.

Dead Battery Leads to Need for Radio & GPS Unlock Codes

After 11 years the battery in the Honda Odessey van needed to be replaced.  Disconnecting the battery enables the anti-theft features in the radio and GPS Navi system (makes them inoperative).  If you can't find the paper work or the sticker on the van then you must get access to the serial number sticker on the radio and/or GPS.

Email from the NHTSA:
NHTSA categorizes vehicles by class and “curb” weight. Curb weight is the weight of a vehicle with standard equipment including the maximum capacity of fuel, oil, coolant, and air conditioning. Passenger cars are further subdivided.

This has raised the following questions:
I don't see an upper limit on the curb weight of the passenger cars heavy category and no weights for SUV, PU and VAN?
Where on the vehicle do I get the curb weight? (GVW - PayLoad = Curb Weight).

Window Sticker (Wiki: Monroney sticker)

The sticker is mainly concerned with identifying the make and model, then price and fuel economy.

This sticker does not contain vehicle weights.  The Gross weights are on a sticker on the driver's side door jamb.  Still looking for a source for the curb weights.

There was a major emissions scandal with Volkswagen (Wiki) that was related to cheating on emissions tests.  This affected VW & Audi cars.
2023 Dec: Engine maker Cummins agrees to pay $1.67 billion to settle claims it bypassed emissions tests - "The Justice Department accuses Cummins of installing defeat devices — which can bypass or defeat emissions controls — on 630,000 2013-2019 Ram 2500 and 3500 pickup truck engines, as well as undisclosed auxiliary emission control devices on 330,000 2019-2023 Ram 2500 and 3500 pickup truck engines."

In the VW case there was a major buyback of diesel cars.  I expect there will be a major buy back and/or recall so that vehicles will be compliant.
AFAICR in the VW case the performance was not acceptable when the defeat device was removed and so the owners demanded a buy back.  I expect this may happen with diesel RAM pickup trucks.

Unintended Consequences

Added this paragraph after seeing YouTube: Great Moments in Unintended Consequences: Gun Buybacks, Poppy Payday, CAFE Standards (Vol. 13), 3:05 - @2:01 - 1975, CAFE fuel economy standards (Wiki)  - this is why 80% of vechicles now sold in the US are categorized as trucks even though they have a strong resemblance to a car.

Pickup Trucks

For some time I've noticed that almost all the pickup trucks I see have 4 doors and a short bed.  I consider these luxury vehicles rather than working trucks.
But recently (2023 Nov) I've discovered that you can still buy a regular cab long bed pickup truck.

Ford F-150, Regular cab, 4x2, Engine: 3.3L (std), options: 2.7L or 5.0L (WB: 145.4" = 67.1 bed) Payload rating 3,310 lbs: "When properly equipped, Max payload on F-150 Regular Cab 8' box 4x2 with available 5.0L engine and Max Trailer Tow and Heavy Duty Payload Pkgs.  Class is Full-Size Pickups under 8,500 lbs. GVWR.  May payload varies and is based on accessories and vehicle configuration.  See label on doorjamb for carrying capacity of a specific vehicle."

GMC Sierra 1500, in the regular cab, 4x2 configuration the payload is around 2200 lbs, i.e. over a ton, not the 3/4 ton that "1500" implies.

'29 Phantom II & '34 20/25 Rolls Royce (on separate web page)

I have owned a number of other cars including a '29 Phantom II (WJ14) and '34 RR 20/25 (GWE72).  Note that Rolls Royce was founded because other contemporary cars were well known for "failing to proceed".  RR won many races, not because they were fast, but rather because the made it to the finish line.  Reliability was the number one concern.  These are both works of art.  The firewall is an aluminum casting.  There are no rubber parts other than the tires.  The fuel line between the frame and the engine is metal with about 5 turns to allow for the rocking movement of the engine.  Note that rubber (and it's modern replacements) bio-degrade when exposed to air or water.   India was a British crown colony and the source of Gutta-percha (Wiki) so rubber was commonly used in English products, even if that made them less reliable.  I believe this is the cause of many "failures" in cars.  The '29 Phantom II was made close enough to the beginning of automobiles that it still had the "start from the switch" function although it also had an electric starter.  Early cars did not have electric starters, they had a crank that needed to be turned to get the engine going.  RR (and probably others) had a feature related to the manual spark timing lever at the center of the steering wheel.  When you were about to turn off the engine, you first put the advance lever all the way up, then turned off the ignition switch (the key was separate from the switch).  In this way the engine would turn over maybe a turn or two with no spark and in the process inhale some fresh air and gas.  When you wanted to start the car, after shopping or whatever,  you would turn on the ignition switch and then move the advance level smartly down.  This would cause the points to open and fire whichever cylinder was just past top dead center, starting the engine without cranking.  I got this to work, but not all the time.  At the time RR began their business most cars were very unreliable.  Henry Royce worked hard to make a car that was reliable.  To promote the reliability they entered endurance races, where just finishing meant winning.  The early RR cars were made into armored cars (early tanks) and used in the African desert by Sir Lawrence who praised them highly for their reliability.  In the movie Indiana Jones and the Temple of Doom the ruler of the dessert where the temple is located refuses gold and jewelry but accepts a Phantom II RR.  As of about 1988 there was a Phantom II used by a women on the East coast on a regular basis.  Although it will not maintain freeway speeds, it will keep running almost forever.
I bought these at Coys of Kensington.

Trade offs

Using a coiled metal tube between the frame and engine of the 1929 Rolls Royce is an example of getting higher reliability rather than use a rubber hose that will for sure fail because rubber degrades.  

A note on Lucas "prince of DarknessTM" (web page with examples) electrics.  The Lucas relays are in metal cans that use bendable tabs to hold the can onto the base.  But Mercedes Benz relays are hermetically sealed.  The Lucas relays fail often but can be burnished and work again and again, while the MB relays last about as long but don't need the maintenance but at a substantial additional cost.

There's a similar trade-off in headlights.  The early American headlamps combined the filament and reflector into one unit.  There are locating bumps on the headlight that fit into it's socket.  But whenever a new headlamp is fitted it must be aligned to point in the proper direction.  They used to cost less than a dollar.  The Honda uses a fixed reflector and a removable pre-focused lamp.  You just remove the burned out lamp and install the new one.  Done in less than a minute and no alignment, but the lamp costs about $10.  So you trade time and money.

The flashlight bulbs that screwed in had random filament locations and so many flashlights had a provision to adjust the focus.  The later flanged flashlight bulbs had the filament in a predefined location.

Note that as time goes on the cost per hour for a mechanic that know how to work on modern cars is higher every year so it's cost effective to make trades that minimize mechanics time.

Lotus Super 7 (Wiki)

Although I never owned one, but the Lotus Super 7 has held a fascination for me.  This was a car built to be very light (1100 lbs on early models) and had a 4 cylinder engine.  Because of the light weight it does not need a lot of horsepower to go fast.  It is also narrow so that on an autocross circuit the road looks wider allowing the Super Seven to often take top time of the day.  Of course if there was a hot go cart or motorcycle they could take TTOD.  The principal is still true.  If a car was made, say using carbon fiber technology with a goal of minimum weight, it would be even faster than the Super Seven.  (Carol Shelby pitched that idea to Chrysler but they went with the Viper (Wiki) instead)

The Geo metro gets the same or better fuel economy than the Prius.
"... ultra-fuel-efficient Geo Metro XFi model, which delivered as much as 58 miles per gallon..."
The reason given for the 3-wheel design (2 in front) is lower aerodynamic drag (front and back seats, not side by side like the Morgan).
The mule car has a 100 MPH top speed.

Morgan

The Morgan Car Co. in England (yes they are still in business) made a  three wheel "motorcycle".  There is a legal distinction that is still true today, i.e. if it has three wheels it will be treated as a motorcycle by the government licensing agency (the DMV in California).  The idea was to lower the cost of ownership. It had two steering front wheels and a driven rear wheel.  This is a stable configuration meaning that you are less likely to crash it. Search  YouTube for "Bond Bug" (YouTube, Wiki) to see many crashes of a car with 2 rear powered wheels and a single front wheel.  The single steering wheel in front and two driven wheels in back is an unstable configuration.  These definitions come from vehicle dynamics.  The story is that Mr. Morgan, a preacher's son, wanted to take girls out on dates in the new car so it had to have side by side bench seating.  In the nineteen seventies I went to the Morgan factory and asked about a tour.  They said that they did not have the staff to do tours, but that I was welcomed to just walk around and have a look!  It is interesting that wood (not in the frame, but used between the frame and body panels, is a material very much like carbon fiber in plastic.  They both have a lot of strength for their weight.

Note this is the same construction as used on the Rolls Royce PII (chassis: WJ14) that I had.  Coach builders used wood to build the body and set it onto the metal car chassis.

Tri-Hawk (Trihawk)

The Tri-Hawk was made in Dana, Southern California as a autocross car.  It would not roll over and developed very high lateral G forces in turns.  It had both steering and drive on both front wheels supplied by a compact car front engine-drive-line assembly. The single rear wheel was fixed.   Harley Davidson bought them out and offered the car in 1984  but they never installed their V-twin so as to make a modern version of the Morgan e-wheeler.  This would make a desirable modern version of the Morgan.  The key is to lower the center of gravity so that the car will not roll over during hard cornering.  People have been killed driving the original Morgan 3 wheelers in modern times because they have a high CG and can roll over.

Motor Scooter / Mini Bike (Wiki)

While looking for patents related to Golf Carts (I think my Polaris Ranger EV uses a motor and ??? from golf carts) found patents for the Cushman (Wiki) motor scooter and a prior patent for the automatic clutch.  It takes the automatic clutch and the variable speed V-belt pulley to make the Cushman motor scooter.  The Clutch patent included an image of a scooter (without variable speed clutch and used a manual transmission.  It looks like Charles was hired by Cushman and there he came up with the variable ratio V-belt drive.

In the early days of Cushman Motor Works they made gas engines.  The brothers Everett & Leslie have their names on a number of patents.  The patents cover single sylinder gas engines, accessories for those and some agricultural devices that would use the engines.

All through history there have been "hi-tech" fields.  At one time it was designing and building Cathedrals.  At another the Steam powered rail road system.  At all times in history very bright people have spent a large amount of time studying, designing and refining their "hi-tech" products.   A man found that the new horse less carriages were so unreliable that they could not make it across London.  He started his own car company to make a more reliable car.  Henry Royce was an engineer apprenticed at the Baldwin Locomotive works (hi-tech live steam).

Up until 1948 the Fowler company was making and selling live steam "heavy haulage" trucks that out performed diesel based trucks for hauling very heavy loads.

In England there are a large number of people devoted to various hobbies related to live steam and there are quite a number of them in the U.S.

At first steam engines were stationary (Wiki) and used in manufacturing plants to power machinery by means of line shafts and flat leather belts.  Mr. Watts invented a 4-bar linkage used on Beam engines (Wiki), a handsome type of stationary engine.   Later with skids under the steam engine it could pull itself (called a mule or yarder: Wiki) by means of a powered spool and rope, or with carriage wheels it could be pulled by horses - a portable engine (Wiki), a version of this is the "Fire Engine" (Wiki).  Then with the steam engine powering it's own wheels, the traction engine (Wiki).  Traction engines were the predecessors to tractors with large diameter metal wheels, tracks came later.  The Showman's traction engine was used around the Circus and had lights and music.  Some traction engines are very large. A short history of steam. Other traction engines are fractional reproductions made for fun driving.

Note that until the middle of W.W.II that torpedoes used steam power driving a piston engine.  Even after electric torpedoes were introduced the steam version still was in service.

Bucyrus Patents

Engine or Motor?

Note that an engine is a device that burns or otherwise consumes fuel, changing its chemical composition, whereas a motor is a device, which does not change the chemical composition of its energy source.. Examples: starter motor in a car, diesel engine, electric motor, gas engine, Sterling engine, a WWII submarine has motors for propulsion and engines to charge the batteries, most ships have engines. Hydraulic and air powered motors are used for many things.

Ship or Boat?

For a single keel vessel: Has to do with how it leans in a turn.
YouTube: Whiteboard: Difference Between a Ship and a Boat - a ship has the center of gravity above the center of buoyancy so it leans out in a turn.  A submarine has the center of gravity below the center of buoyancy so it leans in when turning.

There are a number of people who have restored and have in excellent working condition all types of steam powered vehicles.  They have meetings where Traction Engines race, have tug of wars, and other events so people can enjoy seeing these magnificent machines working like when they were new.  Some of these huge machines, that I saw in England, were licensed for traveling on public roads (MOT stickers, Wiki).  There is a driving school for traction engines.

Hit & Miss engine (Wiki)

The meaning of the name is that the engine "hits" (the engine fires and has a power stroke) only occasionally and the rest of the time it "misses" or coasts.  The lighter the load the more missis.

Tracks (Wiki)

Tracks are very different from tires (see above) in how they work.

Ground Loading

The wiki Track page shows a number of patents, but also confuses the definition.  They are talking about continuous tracks, but that misses what I think is the point.  In my opinion the whole point of tracks is to reduce the ground pressure.  This is mentioned at the bottom of the advantages paragraph on the Wiki Track page after some other things that are really are not that important.  The examples given are the M1 Abrams tank which has a ground pressure of 15 psi and a typical car which has a ground pressure of 28 to 32 psi.

Note the M1 tank weighs between 60 and 68 tons (120,000 to 136,000 pounds) which means the track area is in the range of 8,000 to 9,066 square inches or 55 to 63 square feet.
If wheels were used a vehicle of this weight would immediately get stuck when driving on anything but a think concrete road.

Note that for balloon tires the inflation pressure is the ground pressure.  This is why ATVs (Wiki) and other off road vehicles use special low inflation pressure tires, both to have a light environmental footprint and to avoid getting stuck.  The Wiki Tire page does not get how they work.  See Tires above.  I've recently been looking at "Fat Tire" bicycles and tricycles that are suitable for driving in snow, sand, mud &Etc. (see M-360)
Also note that trailers use small tires to allow for a wider payload with a maximum eight foot trailer width set by law.  They use high inflation pressure in order to carry more weight.  This is way you don't want to pull a trailer over dirt when loaded.

Traction

The traction (Wiki) of a tracked vehicle is greatly increased by the use of Grousers (Wiki).  This allows tracked vehicles to have drawbar (Wiki) pull much higher than vehicles with tires.  A common fair attraction is the Tractor Pull (Wiki)

Models

You can buy finished live steam models ready to run, kits of parts that are ready to assemble, kits of parts that need some work to assemble, raw castings that need machining, and plans for build form scratch models.  There is a good sized industry in the United Kingdom to fill the needs of this model builder market.  In the U.S. there are a number of live steam railroads built to a scale where people can ride on or in smaller sized rail cars.  Many of these are in peoples gardens.

LGB - these are G scale electric trains. the link is here even they are not steam because I used to have a lot of them.  I found that putting 2 magnets under the engine made the switches work more reliably.  Using the switches you could have layouts with many independent trains all running by themselves.  Since there are only 2 rails the polarity would need to be switched to allow a train to go either way on a given section of track.  I remember one layout that had a yard with 4 trains.  One would let the train go down a long track and at the end go around a loop and come back on the same track.  Near the yard it would branch and go back onto the same track that it came from.  That would release the next train to run.  They would all take their turns.  I resisted the temptation to build my own parts of the system.  If I started doing that, there would be no end to what could be done.  A friend liked to build with Legos.  He built a working grandfather clock that kept time reasonably well, but used only Lego parts, he did not want to get into making his own parts.

Spark Ignition

Patent by the Oliver Lodge (Wiki) of electricity, magnetism & radio fame and his son Alexander:
869208 Electric ignition of explosives, Oliver Joseph Lodge, Alexander Marshall Lodge (Wiki), 1907-10-22, -

Magneto

An alternative form of gas engine ignition is the Magneto (Wiki).  They have a number of advantages.  No battery needed, great for vehicle that's stored longer than shelf life of battery.  Ignition system is light weight so used in aircraft and motorcycles.

Atwater Kent Type B.  Unisparker

The Arthur Atwater Kent company (Wiki) purchased the spark ignition system he sold from Thomas H. McQuown.  This system works on a different principle than the later Kettering (Wiki: Delco) ignition system.  The Kent system used "trembler or buzzer" coils, like on the Ford Model-T (Wiki) (1919 to 1927).  These produce many sparks and if constant power is applied the high voltage will be a constant stream of sparks.  The problem is that it only works on low compression engines and at low RPM.  With the advent of higher compression ratios (Wiki) and higher RPM engines the Kettering system took over.  The Kettering ignition system uses a coil that's just an auto transformer (it has no trembler or buzzer).  The current is going through the coil most of the time so it's magnetically saturated.  At the instant the points break the magnetic field collapses causing a single high voltage pulse on the secondary. 

Functional Description

This is based on looking at the outside since the inside is potted.
The two left terminals marked: INT and G go to the interrupter and engine ground, i.e. the points that make a very brief contact at the moment there should be a spark.
The two right terminals marked: CARBON and ZINC to the the Positive and Negative battery terminals of the series connected ignition batteries.
The center terminal is the High Voltage output.
The On-OFF switch at the top right is for turning the engine on or off.
The START switch at the top left is for "starting off the switch" (Rolls Royce).

Kettering (Delco) Ignition System

The points in the 427 Cobra would "float" at about 5,000 RPM and that was the limit to higher revs, so I had a distributor shop install racing points to raise the RPMs.  More modern spark ignition engines use one HV coil per cylinder thus allowing more time to charge the coil allowing higher RPM operation.  Also this eliminated the distributor (one less thing to go wrong).

Kittering Bug (Wiki)

This is the precursor to the Cruise Missile (Wiki) designed by the same Charles Kettering with the help of Elmer Sperry of Gyroscope fame.  Sperry patented a radio controlled version:

The distance traveled was estimated by using a counter preset to the number of propeller revolutions to the target and counting down. At zero the wings were disconnected and the engine turned off.

Lubrication

Zinc Air (hearing aid) batteries generate hydrogen gas when they have a heavy load.  This can be used to drive a piston and force grease into a bearing over a time span measured in months.
Rolls Royce used the Bijur chassis lubrication system on their early cars.
Note this is very similar to the problem of putting air into tires.

Button Head Fittings 1922

I remember using this one on my uncle's heavy earth moving equipment.  Sometimes the grease gun would pop off the Zerk fitting.  This alternate type grease fitting looked like a disk maybe 3/4" in diameter and the grease gun would surround the disk so no matter how much pressure there was it never could pop off.  This grease gun had a tub that sat on the ground and held over a gallon of grease.  The pumping level was on the tub so you could apply much more force than with a hand held cartridge type grease gun.

Trafficators & Turn Signals

The 20/25 Rolls used Trafficdators.  The switch on the instrument panel activated one or the other and included a timer function, not sure if clockwork or pneumatic.
Was reminded about these on YouTube:


Traffic Lights (Wiki)

I interviewed for an engineering job related to a start up company making traffic light controllers.  You could drive all around the building through the parking lot so they had loops in the parking lot that allowed testing the controllers.  There was an intersection in Los Altos which flashed red in all directions at night when there was no traffic.  As you approached the light it would turn green so you didn't need to stop.  Very cleaver.

Engineering Trade-offs

When designing a product there are always considerations of schedule and price and sometimes one of these may be the critical design parameter.  The normal case is when functional engineering decisions are made.

I attended a lecture by Charles and Ray Eames (Wiki) where they said a product designed when the life of the user is at stake did not contain any marketing elements and so tended to be elegant.  This is related to the Form Follows Function school of design (Wiki).  The example given was the gyroscope used in aircraft.

There are conflicting functions for any vehicle and they may be Performance, Utility, Luxury and Economy.  There are many performance parameters such as top speed, gas mileage, range, &Etc.  Utility vehicles need to do the job they were designed to do at the lowest cost point.  Luxury vehicles tend to give up on all the other factors.  Economy vehicles give up on the other factors, &Etc.

Vehicles that are aimed at general markets tend to be a blend of Performance, Utility, Luxury and Economy.  But a blended design can not come close to a purpose designed vehicle where only one goal is present.  The family sedan can not set a world land speed record.

As of 2023 full size pickup trucks seem to be only available as luxury vehicles with 4 doors and a plush interior.  For some reason none of the major car companies is making a utility pickup truck.

A multi-tool that does many things can not compete with a single purpose tool when used for it's stated task.

Mean Time Between Failures

A possible design consideration is Mean Time Between Failures (Wiki: MTBF).  I learned about this when I was engineering products for military applications where MIL-HDBK-217 was the defining document introduced in 1961.  I also had a conversation with another engineer who worked at RCA and was involved in the design of color TV picture tubes where the goal was to get the MTBF at one year plus one day.  That's to say just after the warranty ran out.  While not the same as the "sell razor blades not razors" business model (Wiki), it's in the same ballpark.  This would allow RCA to sell a second picture tube and give employment to the local TV shop.

Individual components can be tested to determine the parameters needed as inputs to the MIL-HDBK-217 calculations.  Then these components can be combined to make a sub assembly where its MTBF can be computed.  These sub assemblies can be combined into a sub system with its MTBF and so on.  Thus the MTBF for a complete aircraft outfitted for a specific mission can be calculated.  The idea is that the MTBF should be longer (maybe 4 times longer) than the total mission time.  It's my recollection that an early F-111 (Wiki) had failures during a mission and the guys at Aertech who made some parts for the terrain following radar were nervous until they learned is was not their component that failed.  IN any case the MTBF was shorter than the mission time.

I think MTBF should be a required part of a product label.  The idea is to let the buyer know the longevity of the product.  Some buyers may want to pay less and get a product that's only going to last a year while others may want to pay more and have a longer lasting product.  This has implications when deciding to make a major repair.  On a car with a short MTBF making a major repair may be a waste of money, but on a car with a longer MTBF might be an excellent investment.

At the end of the movie Blues Brothers (IMDB) the car they were driving throughout the movie disintegrates.  This is the ideal case of matching of MTBFs for all the components of the car.  If, for example, one part of the car has a much longer MTBF than the rest of the car then that part can be re-engineered to have a lower cost and shorter MTBF thus lowering the cost of the car without impacting anything else.

While electric vehicles have many advantages (see my Polaris EV) there may be a problem relating to MTBF.  Currently it pays for manufacturers who produce high quantities of a single product to spend say $10,000 to lower the cost of a part by one cent that will go into a million products.  The amortized cost of the engineering is $10,000/1,000,000 = 0.01, i.e. a penny.  The proviso is that the MTBF of the part needs to be greater or equal to the MTBF of the final product.  So this cost reduction is aimed at parts that have an MTBF that's too high which are typically higher quality parts.  That's to say those parts need to be made cheaper in both the literal and figurative sense.

If the car is designed so that the car's MTBF and the battery MTBF are about the same then the whole car is considered a one time use product to be dismantled/scrapped at the end of it's life.  This seems to be the case for most products.  (2022 June: PS Last night I replaced a 3-way lamp socket because it was not working.  The store clerk said he did not see many people repairing products much any more.)  Most of today's products seem to be single use.  This is not sustainable in the long haul.

The implication is that electric (or really any) car (product) that is designed to a specific MTBF will have lower quality parts.  Unlike early Rolls Royce cars that were designed to last as long as possible.  That's why the Phantom II and 20/25 models will by functional for a minimum of 100 years.

My 2003 Mercedes Benz has plastic parts in the engine cooling system that have a life on the order of 20 years.  It's not that they fail at 20 years so much as it is that if a mechanic touches one of them to replace a sensor the plastic part breaks.  As long as replacement parts are available or the broken part can be repaired the car can be kept on the road.  But you can see that at some point the car must be scrapped.  This is very different from the early Rolls Royce cars that do not have plastic and rubber parts with a limited life.

A possible solution would be to go back to the system where the chassis and coach/body were made as different assemblies.  That way the power train (electric motor and battery) could be thrown away/recycled and the higher quality body could be kept in service.  This is backwards from how it used to be.  My RR Phantom II body fell out of style and was removed from the chassis (which was the high MTBF part of the car) and a delivery truck body was fitted.  But currently it would make sense to have the high MTBF part of the car be the body on high end cars.

For low end cars they will just be scrapped (Wiki) at the end of their life. 

2023 Oct - New considerations:
1. Because of the problem the lack of a way to put out an EV fire, insurance for EVs will soon become very expensive and they will be banned from some locations.
2. A gas station has a large storage tank in the ground and so can fill dozens of cars at the same time.  Since there is currently no practical grid level electrical storage system it will not be possible to have an electrical charging station with a dozen charge points, or if they do that the capacity of each charge point will be reduced.

Pete Brock was big on the idea that engines (and vehicles) should be very reliable as well as fuel efficient and easy to repair.  His idea was a low BMEP (Wiki) engine was superior to a high BMEP engine.  Also he used the same size hex bolt throughout the engine.  If more strength was needed he used two bolts.  That was a single size hex tool, that also could be made to be a torque limiter, would be needed for engine work.

Note electric vehicles control the battery use (minimum depth of discharge, maximum charge) in such a way as to extend the battery life at the expense of restricting range.  This way they hope to get a desired MTBF for the battery.  Since the battery is not easily replaced that means the vehicle will also be designed to have the same MTBF.  The end result is that most EVs will be on the cheap side.  Note the EU ruled on 30 June 2023 that cell phones need to have user replaceable batteries.  This is because cell phones are thrown away when their battery fails.  This has happened to my last three cell phones.  If EVs have owner replaceable batteries then the MTBF for the car can be longer than the battery and so of a higher quality.  That might allow battery swapping if the process is designed for "quick change" batteries, which would make commercial use practical.  As it is a commercial user needs to have his economic assets in use for as many hours a day as possible, so waiting hours for a non-replaceable battery to charge is a deal breaker.

2023 Oct - there have been a few YouTube videos about things like $5,600 to replace a Ford pickup tail light, a quotation of $41,000 to fix a dent in a Rivian pickup truck, A friend just told me he installed new wiring on an RV for high and low beam headlights for about $10 in parts where the dealer quote was for $7,500 to replace a wiring harness.  This points in the direction that modern vehicles may be getting to the point where they are disposable rather than repairable.

A symptom of this is the lack of new cars because of supply line disruptions because of COVID-19.

Another symptom is my local Mercedes Benz dealer will no longer work on my C230 because it's too old.  I'm guessing that they can no longer get parts and don't want to install after market parts, so just will not work on my car.  Note that the 1929 and 1934 Rolls Royce cars my son now has can be maintained for centuries to come.  But cars that contain electronics will become bricks when those parts are no longer available.  You can see this when companies sell product lines to what may be called after market test equipment companies.  The new company raises the price by a large multiplier and tells the government (and all customers)  that's the price if they want that piece of equipment.

Also a major EV maker in China has gone bankrupt and because their internet server is no longer on line the cars they made are susceptible to being bricked (Wiki).  This is different than although related to the right to repair issue of John Deer tractors, Apple products &Etc. (Wiki).

There may be a market for a utility vehicle that uses parts that are available world wide in large numbers, i.e. that is easy to source to manufacturer and easy to get repair parts.  Rather than use a wire harness it would use cable management so that a repair would only require a spool of wire. It would not use electronic ICs that are custom made, but could use generic ICs that have multiple sources.

Body on Frame - Unibody

In the horse and buggy days "coach builders" built the coach part which was then placed on a frame.  When automobiles were invented the same coach builders made bodies for cars.  So for may decades Rolls Royce (see: PII & 20/25) did make complete cars but rather made the chassis, and companies like Barker would make the coach work.  Later the car manufacturer made both the frame and body.  Note heavy duty vehicles like trucks have always been body on frame (Wiki) construction  because it's stronger than unibody construction.

The following cars are held in high regard and I think the key reason is they are the last body on frame cars by Chevrolet and Ford.  All cars since have been unibody which is lower cost to make, but not as rugged.  It may be that a body on frame car can handle more engine torque than a unibody and so for cars with more powerful engines a frame is needed.

1957 Chevrolet Bel Aire (Wiki)

1957 was the last year Chevrolet made cars with a separate frame and body.  There is no Wiki page for 1958 Chevrolet probably because they were made using unibody construction.  The 283 cu in engine with factory fuel injection achieved 1 HP per cu in, a first for Chevrolet (Wiki).

1996 Chevrolet Caprice (Wiki)

The last year Chevrolet made the Caprice body on frame car in the U.S. was 1996.  GM did continue to make them in Australia under the Holden (Wiki) brand up until 2017.

2011 Crown Victoria (Wiki)

2011 was the last year Ford made a car using body on frame construction.  Versions of this design were and still are used by police (Wiki) and taxi cab companies because of the longevity and ease of repair.

Fuel Efficiency

Miles per gallon has been the metric for quite some time.  But the introduction of alternative fuels has complicated the comparison.  Now new cars are labeled with MPGe (Wiki).  This is based on the energy content of various fuels (Wiki).  Note the table says 34.02 kWh/Gallon, but the EPA uses 33.7 kWh/Gallon.

The Delsbo Electric contest in Sweden (New Atlas: June 2019) the new record is "0.603 watt-hours per person per kilometer" (when 6 people are on board with a total people weight of 660 lbs.)  The actual vehicle therefore comes in at 6 * 0.603 Wh/km = 3.618 Wh/km = 3.618 Wh * (1 km/0.6213712 miles) = 5.82 Wh/mile.  This is done on train tracks, not on a road using tires.  Using the EPA value of 33.7 kWh/Gallon = 33,700 Wh/Gallon gives about 8,000 MPGe.

The Tesla Model S is rated about 104 MPGe.  Delsbo says the Eximus III is about 76.4 times more efficient than the Tesla Model S, or 7945 MPGe.

Self reporting by the CSX railroad says they get 471 ton-miles per gallon of Diesel fuel whereas trucks get 134 MPG on Diesel.
These translate to 418 MPG for rail and 118 MPG for trucks on gasoline because Diesel contains more energy per gallon than gasoline.
But how the weight (note: ton-miles) effects the results depends on the elevation changes of the routes used for the annual calculation.
A horsepower (Wiki) is defined as lifting 550 pounds one foot in one second.   Also see M-360 eTrike hill climbing.

So the Delsbo results are biased because they are run on a level RR track.  It's similar to measuring gas mileage on a level track on a windless day.  Much better to make these measurements on some stated course, like the CSX railroad using all the routes they have.

Harry Ricardo

Got his start by winning a 1904 contest to see how far a contestant could go on an Imperial quart of petrol.  He went 40 miles, i.e. 160 MPG (Wiki).  He did that by optimizing everything he could think of for maximum fuel efficiency.

He holds over 100 patents related to engines. including US1677249 Method of making sleeve valves, 1928-07-17.  Wiki says he didn't invent them but wrote an extensive paper.

Vehicle Tracking

In the movies it's sometimes said that the GPS system knows where a GPS receiver is located and that by hacking the GPS system that location can be found out.  That's not the case.  The GPS satellites only transmit to the GPS receivers.  The GPS receiver does not transmit any data back to the satellite.  also see Key, Object & Pet Location Tags.

Cars, Trucks, Motorcycles &Etc.

There are a number of ways cars can be tracked.  For example by the use of bridge toll transponderes or license plate cameras (see FasTrak).  If the car has it's own cell phone, such as the On Star system, then there are many ways cell phones can be tracked (see: Spying on Cell Phones).  There are many "GPS Trackers" sold on eBay.  These combine a GPS receiver and a Cell phone which places a call from the tracked item.  These only work if the GPS antenna can see the sky AND the cell phone antenna can connect with a cell tower for the provider.  The newest wrinkle is the use of the Apple AirTag.

License Plate Recorders/Cameras

For more see FasTrak\LPR.

Aircraft

Most modern aircraft now have ADS-B (Wiki) transponders.  There are a number of services, like FlightRadar24, that consolidate that information and present it on a world map so that you can see pretty much all aircraft traffic in the world.  Note that ADS-B works in conjunction with the 1 GHz IFF (Wiki)/Aircraft Transponder system (Wiki, SSR)) so is not available over oceans.

Ships

Most commercial ships have a transponder and can be tracked using something like Ship Tracker.  This makes use of Automatic Identification System (Wiki: AIS).  Most of these ships transmit the AIS information on a VHF radio channel (about 162 MHz).  There is a Satellite version (S-AIS) and a Long-range Identification version (Wiki: LRIT) that will work in the oceans.

Idea for weighing Vehicle

When figuring out the weight transfer on an electric trike I used an industrial platform scale.

Today I saw this YouTube: I Invented a Better Way to Weigh Your Car. And it's Cheaper, Too, 7:20 - He spends the first half talking about failed ideas then @4:59 SuperFastMatt describes "The Better Idea" of using a wheel dolly and 4 load cells.  He used the Sunex 1500-Pound Wheel Dolly (needs to be hydraulic or ratchet jack type) and FSK Livestock Scale Kit Build Your Own Scale at a Fraction of the Price (includes 4 load cells, 20,000 # max) both on Amazon for a total under $400.  The beauty of his idea is it's very quick to measure the weight.

Note vehicles that have a GVW greater than 10,000# have fewer rules than lighter vehicles.  So a 20,000# weight for one wheel may be overkill. 5,000# total for the 4 load cells costs less and has finer resolution.
