1955 two-cylinder F1 engine

Manel, if you send me a PM with your email address I will send you some scanned material about the twin-cylinder engine. I don't have time to type it up right now.

Mount it on the front of a Morgan 3 wheeler!

That looks like a cool engine.

If I recall correctly, they never put that engine in a car because they couldn't build a dyno that could take the vibrations. The Morgan 3 wheeler would have been really interesting if that's true.

 

David Clark at one time owned this.

Where is it now?

 

I don't know if it's the same engine or not, but there is a 2 cyl engine featured on the Ferrari Victory By Design DVD.

 

The engine in post #2 does not look like a 2 cylinder engine. Why would the valve covers need to be so LONG if they are only covering ONE cylinder on each bank? Do they mean 2 cylinders on EACH bank?

 

Oh, I don't know - the perspective may make it look longer than it is. You need length enough for the cam gears and 4 valves per BIG cyl - each displaced 1250cc! It looks like a in-line twin, not a V. I've no idea what the shorter two towers are - ballance shafts?

 

There are not two banks of cylinders. You are seeing two cam shaft covers.
This is a DOHC 4 valve engine. Separate covers for each cam.

Some of Ferrari's 4 cylinder engines used the same design elements.

 

Arlie,

The engine looks like an inline DOHC 2 cylinder. These are obviously problematic as either the pistons move up and down at the same time so the firing is even, or they move opposite each other (a la John Deere!) to keep the engine from hopping up and down, but uneven firing. It surprises me Ferrari would even bother with such an engine!

If it is a 2 cylinder, then I would assume that the 4 ports on the left side are the intakes for a pair of 2BBL carbs (Weber?). It looks like an exhaust port on the right hand side. Looks like no exhaust manifold, just an open pair of exhaust ports barely visable.

 

That's what it looks like to me too.

 

Makes sense. there is a photo of this engine in old Sports Car World Magazine (Australian) from the Eighties, the story is about David Clark.

I dont have it handy, but have it somewhere!

 

There is another built in the nineties? Experimental engine that was built by Ferrari apprentices I think.

It was an exhibit in the Galleria.

 

As someone already mentioned, it would be interesting to find out what the two small "towers" for lack of a better word , are used for. Anyone know?

They are breathers. In a 360 degree twin the pistons pump engine displacement air volumes through the crankcase.

I've heard this type of engine referred to as a 'Thumper.'

Does anyone know how fast they intended to spin the thing?

Ferrari bothered to try many engine configurations that were commonly thought to be problematic or "not worth all the trouble" at the time. Let's take the whole V-12 range in general and large (3-litre and 3.5 litre) 4-cylinder engines as examples.

 

please send to [email protected]

thanks

 

Wow, from six years ago! I'll see if I can find the reference and send it to you later today, OK?

 

hey Jeff,

thanks for prompt reply, i was telling my son about this engine but counldnt recall
which magazine had featured it. I have the magazine buried somewhere, so now the
