Ducati V8 SS?

Cat0020 · 10-25-2010, 09:52 AM

This was on display at the Intermot bike show in Colonge Germany this year,

Very interesting connection between 4 cylinder heads into 2 then a single pin crank shaft.

Cool!

I'm not quite getting how the reciprocating pistons hit TDC in each of the cylinder banks?

Intermot is held in Cologne Germany, not France. Wars have been fought over details like that.

Looks like the outside pistons pivot on a rocker arm.

Actually, to further clear up details, Intermot is held every 2 years, and while currently in Cologne, there is every possibility it could return to Munich where it has been held previously.

Looks to me like the outside pistons, when pushed down, work that 'rocker arm' and actually help to push the inside pistons upward.

Ingenious, but I'm not entirely sure of the merit behind it, especially with seeing how two pistons are always at TDC at the same time. Seems to me this is an engineering problem solved much easier with a V4 and no common crank pins.

Yeah but then you'd have a V4 built on a Ducati case instead of a V8, and therefore it would only be half as cool.

Wasn't there a Moto Guzzi V8 concept a few years back? I don't mean the racing bikes of the 50's but a modern day design exercise. Very slick if I recall.

GB · 10-26-2010, 02:38 PM

What's the displacement in cc's?

RedDogAlberta · 10-26-2010, 02:46 PM

Looks like it says 868cc on the case there.

GB · 10-26-2010, 02:48 PM

Damn, I need a better monitor

I can't see anything on the engine casing, just blurry letters..

Tripped1 · 10-26-2010, 02:52 PM

That is really an interesting arrangement.

45* crank-pin, 90* firing order, SOHC cam.....one can only assume that the cams are chain driven via that void between cylinders. Doesn't look like they have worked out exhaust routing yet....I can't blame them, that looks to be quite a bear.

I wonder how well it works.

RedDogAlberta · 10-26-2010, 02:55 PM

Yes, I wonder if the front cylinders would exit via a conventional muffler or mufflers while the rear bank would exit under the seat? There could be some interesting plumbing there. I also note the lack of a Ducati name on the machine itself aside from part of the engine, which would have it if that was the base platform used.

This is the design.

And this is the 4 cylinder prototype.

This is one of his projects - Ducati-Elenore 868cc V8

Here is his website.
