Something interesting with new motorcycle motors being made

rather neat set up

We are ready for a better engine design. I'd sure like to see something good make it to mass market.
Less moving parts is always good.

I like it.

Commercial Marine is watching the Duke company closely. The engine can run on multiple fuels, not just gasoline!

What will they think of next?

The last radical design motor to make it to production didn't last very long. The Wankel rotary engine. The designer claimed it could run on hot butter and proved it.

Impressive design.

NICE , did anybody watch the 5 stroke Eng. after this plays ???? Interesting . opcorn:

Same concept as the GM A6 A/C compressors from the '60-'70s. :mrgreen:

That was my first thought - a swash plate compressor. I'm curious as to how they seal it with rotating cylinders sharing spark plugs, and no valves...

The "no valves" is a common setup. 2 stroke opposed piston diesels have been using intake and exhaust ports with no valves for many years. The original steam engines also used no valves, only ports.

I could be wrong (and mostly am wrong) but I thought there was a type of radial airplane engine that also used no valves.

The Wankel Rotary also had no valves...

I get the "no valves", I just wonder how they seal the rotating cylinders. The Wankel is a great design, but it has always had sealing problems. We shall see...

Looks like the cylinders and pistons rotate together.
Must be an interesting trick sealing them.
