We have high hopes that the Duke engine will become the the world’s first internal combustion engine to run on such a wide variety of fuels.

That's not true. M35 2 1/2 ton truck could be run on gas/diesel/kerosene.

“If it does not produce heat, and I cannot imagine that it does, or at least not much, how is it robbing power? “

Everything in an engine robs power and creates heat.

Ah, that great engineering reference, Wikipedia....

Emissions will be mitigated through electronic engine controls. That’s how the same basic IC engine that was in Andy Griffith’s squadcar now gets 30 mpg.

My thought as well - sounds like a wobble compressor.

It’ll never work. The camliner in the heel plate will be dust after only 1000 kbms. They keep trying to foist these gimmicks on a gullible public, but just wait till the flaksticker blows out at a million cycles plus and the exponential hydra effect will level a city block.

“Charge motion development will further improve our combustion efficiency to approach that of a conventional 4-stroke.

There is currently some oil required for the seals to work and this can add to the emissions, however our consumption is far less than that required for a 2-stroke or rotary.”

Maybe it’ll be the new weedeater engine ;- )

It requires blinker fluid and muffler bearings.

Would be a great ATV/4 wheeler engine.

Just change the swash plate angle.

They have a certain leak rate past the kidney plate. I hope thewrong oil vis is all that is wrong with one Im wrestling with.

Steam would be really neat

I wound up using good old cylinder oil. Messy but steam is just that way.

The rotation inside a rotation has me worried. Dyna-Cam had valves, I often wondered why their wasn't a 2 stroke version. Some things I have read about synosodial motion might have wear problems...

I don't know if it ran the best barrel engine concept IMHO is here: http://www.google.com/patents/US20080302343

Most under noticed engine? The Erickson Motors Full Expansion Engine: http://www.ericksonmotors.com/

The guys that might have solved the Charge Cooled Wankel issues and are here now? The Rotron with their water cooled shaft and unique way of cooling the rotor(s): http://www.google.com/patents/US20140140878

You had to look hard to find that oil!

I will admit I had 460 in stock for another project. A Chevron jobber should be able to get you some in quarts or hook you up with a user in your area.

Duke has been developing this engine for 22 years. Here is a good summary of axial piston swash-plate engines.

Please note that “no axial IC engines have achieved any sustained success”.
