Interesting engine - the Duke

Looks damn impressive to me, although that may just be the pretty graphics and 3D CAD renderings.

Thanks Marty! Impressive it is but will it ever make it to the market place?

Don't know, but I like their stats...

103Hp at 3300 RPM on 2.0 litre engine weighing 46kg with no need for a gearbox, and the rotating engine partially cancels out gyroscopic effects. Plus it's got a nice cylindrical shape making it easier to cowl nicely!

You will have to fit a radiator somewhere. It is designed like a swashplate variable output hydraulic pump. Nerv

 

 

[Marty_d]

True. Chin mounted radiator perhaps. I think the general idea is very clever though.

Why do we have two threads on this engine?

But I missed how the head gasket fits, if the cylinders are moving.

thats what im thinking, how do you keep the compression and combustion gas pressures in check with a moving cylinder and fixed head?

 

 

[Old Koreelah]

My Ducati had no head gaskets. Compression relied on a good overlap fit between head and barrel. Some of the sealing technology developed for Wankel rotaries might have been adapted to this engine.

Sorry OK - I saw this on another site and got all excited about it, didn't think to search for it on this one!

All good posts, Marty. Perhaps mod. can combine the two threads.
