Possible applications in boats?

Very interesting concept. It would open up the engine bay area quite a bit, however Im not thinking there going to make north of 500 HP.

Sounds like Mr. Wankel had a cousin ..... But we all know how good those were...

there a bit vague but it looks like a pistol revolving barrel with the pistons turning against a stationary cylinder head with the valves and combustion chamber thats got to be quite hard to seal rotarys can do it but it took many years to get it right i remember rebuilding a 12a i think i spent a week getting all the little sealing parts to stay in place on the rotor

.


I'm also concerned that when the fuel/air mixture charge is released into a moving cylinder, will the fuel/air mixture congregate to one side of the cylinder because the cylinders are in motion but NOT the fuel/air charge?

on second thought, this might actually help increase the burn efficiency of the fuel/air mixture, much like how the Dodge Hemi's work.

The piston is hemispherical thus causing more turbulence inside the cylinder to maximize the fuel/air volume to enter the cylinder. http://en.wikipedia.org/wiki/Hemi_engine

I've read that the Duke Engine does not show detonation at any speed, this is proly how they achieved this....using turbulence....wow!

how do you suppose they sealed it? maybe a flat round surface ring? or straight seals with corners?

Looks like an automotive a/c compressor in concept, doing the turning instead of being turned. randy

I contacted this manufacturer about two years ago and they stated the primary application was centered around aircraft and didn't offer much hope for marine use.

I liked the smooth operation and compact design.

The vertical position is ideal for outboards.

I hope they didn't scrap it, but marine use was in their minds, or maybe it is today?
