Unusual engine photos

Unknown marine engine that popped up for sale.

 

1920 Stutz

 

That is a piece of jewelry. T head, I presume.

 

There are a few posts on You Tube on the engines Ardema and Braun have built. Pete will put a overhead cam on anything including a Flathead Ford.

 

I've seen Ford Engineering T prototype engines from the era. Anything you can think of was tried back then.
A few examples
- OHC cam driven by bevel gears
- 5-cylinder version
- the infamous "X" motor; two pairs of 4 cylinders arranged in radial fashion

 

Never heard of a X motor before,advanced technology and design to be from 1935.

 

Note the year on the drawing!

 

Ford was working on the X8 as early as 1920; as seen in the cartoon above some were water cooled designs. None were marketable.

 

so the Stutz shown above has dual spark plugs...

 

This is not as unusual compared to the others here, but this is my chrome head Lincoln V12. I got it here on the HAMB a few years ago. I still have to get some things squared away before I can tinker with it. My 39 Zephyr is still in storage as well.

 

Deserves a bigger pic

 

Were they factory chromed? '39 Zephyr coupe is one good looking car!!

 

I think Remington rifles were built that way - interchangeable parts.

 

No not from the factory. The previous owner was an avid collector though

 

Packard straight 12. I understand they built only one or two of these as a prototype and decided against it.

Stanley steamer steam engine 2 cylinder 20hp. these next 2 pictures I got from the internet

 

That's actually the boiler, not the engine. The engine is located in the rear.

 

Have y'all seen the Jay Leno YouTube (might have been a My Classic car) where he is hot rodding a Stanley steemer, they were on their fifth or six rendition of different baffles in the boiler trying to keep the pressure up so they could go faster longer. Hot rodding is universal.

 

The one-piece aluminum crankcase for the Duesenberg straight-12 engine.
One of the largest aluminum forgings made at the time and weighed 365 lb (166 kg).

 

V-12 Jag

 

Is that a V12 or a 4V DOHC V6?
Either way it is an interesting example of using the engine as a stressed chassis member.

 

It is the V12 and yes Jag did use the engine as a stressed member. Very high level of engineering.

 

Gear drive Ford

 

Interesting that one cam turns clockwise and the other cam turns counterclockwise. I wonder if the cams were the same but able to be swapped end-for-end? That would have simplified things.

FE SOHC

 

From Mac's Motor City Garage:
"Drag racers burned midnight oil tackling the Cammer’s issues, including the mile-long timing chain. Working with Harvey Crane of Crane Cams and P&S Machine, the always creative Pete Robinson produced this gear drive system. Note the additional gear on the left bank, allowing a right-hand camshaft to be used on both cylinder heads."

I'm still trying to wrap my head around the gear train. How do you wind up with 2:1 crank to cam ratio with the different tooth counts left & right?

 

How do you wind up with 2:1 crank to cam ratio with the different tooth counts left & right?[/QUOTE]

The different tooth count cancels out. First it goes 1:2 from big gear to little gear. Then back down 2:1 from little gear to big gear.

 

Ahaa! I guessed correctly.

 

FFF,
You and Pete Robinson are my heros!
