Unusual engine photos

That is an interesting pic. In studying the front gear drive it appears each bank of cylinders has its own magneto to fire the plugs. What I don't get is it looks like they are driven 1:1 with the crankshaft, meaning each plug must have been firing on every revolution? I know some coil-on-plug modern systems do this too - called a "lost spark system" sometimes. Is that what I'm seeing? Once again I'm reminded that as far as engine design goes nothing is "new".

 

Don't know about the Fiat but Harleys used 'lost or wasted spark' since Moses was a youngster.

 

Posted before. Recent repop of Stephens heads. Has run well in SCTA events. Original were iron. New ones are a lot lighter.

 

Wasted spark systems are actually pretty common-- the Mitsubishi 4G63 (think early turbo Eclipses... I used to campaign a 600ish hp AWD car many years ago) a number of Mercedes 6's, the Buick 3800, Harley twins, and going way back to 1940's Citroen 2CVs. It is also a common 'simplification' to home-built distribution systems as the spark signal is easier to time... piston up, light the match. I think of it as "reasonable laziness" engineering.

 

And, of course, pretty much every pre-computerized motorcycle.

 

That's got a rather Teutonic bulbousness about it. It looks like something BMW might have built in 1954.

Here is what BMW actually did build in 1954:

 

Funny. My first impression when I saw it was some fat German tinkerer adapted a pie pan or something from the bakery he runs, then threw on a couple of wingnuts from the junk drawer to hold it on.

Next, I thought of these very common (in colder climates) thing. Simple, ugly, but functional...

 

Early Buick Engine.

 

Hendee 8 cylinder water cooled engine built by Hendee Manufacturing, builders of Indian Motorcycles.

 

Let me just say that I know motorcycles are taboo here, but this ones got an interesting power plant.

That's a beauty for sure. Was this something that was used in midgets or other dirt track cars?

Don't know it was before my time

 

Daimler-Benz LOF-6 16 cylinder engine. This is the type of engine used in the Hindenberg.

 

1928 Dual 91 ci inline 8 cylinder engines using 2 cranks in a common crankcase.

 

Earlymopar : Based on the photos behind the engines & displacement limits They were used in Sprints & not in Midgets.

 

Slightly unusual

Hal Indy

You forgot Hal Midget.

 

Possibly the Studebaker done for J C Agajanian Indy effort in the early fifties ? The engine never actually made it to Indy.

 

I think most of the engines were salvaged and preserved. They're on display at a few museums. They are huge, about 5400 cubic inches. They were diesels that put out over 1300 hp.

 

Love the look of this proposal from the streamline era.
Like a Buck Rogers 1939 movie prop.



Crosley 1702 cubic inch X-24 Defender

On May12th 1942 a report was submitted to Ray Olson Jr of the Navy Department proposing an all new 24 cylinder aircraft engine, designed by Taylor Engine of California (3 man team). This would be a fabricated block construction on a tubular one piece crankcase with 7 mains engine using ideas developed by Daimler and Mercedes-Benz in the early years of the automobile as well as the 27 liter Liberty V-12 aircraft engine during WW-1.



Four 6 cylinder banks 90 degrees apart.


HP estimated from the 950-1050lb package:

Un-Supercharged 1000 HP
Supercharged 32 In.* 1,250 HP
Supercharged 39 In.* 1,600 HP
Supercharged 48 In.* 2,000 HP

*Manifold pressure in inches of mercury(hg).


The overall size with tapered nose for the prop and the rear accessory drive assembly was 76 inches and 45.5 inches in diameter. It was interesting to look at the drawings and see if the front nose and rear assembly was removed, the engine was almost a perfect cube and would have fit in a 36 X 35 inch box.


Proposed for aircraft use but for any use where space and weight was a important.

There is no indication that the X-24 was ever built.

I have no idea what type engine this is it just has such a cool look to it.

 

1925 Henderon V-8

 

1903 Premier. It was a pentroof head hemi head design. It was also OHC, which is completely exposed up top, and the crank and rods were exposed at the bottom. Yikes.

 

Pretty sure those are Birner heads on a flatty,one of very few sets. The stude Indy effort was dohc.

Well that must have used/spit oil every where!

 

I don't know what year this Comet was built or raced but here's a picture of the engine and the car.
