So, what class would this engine run in?

I don't know what class this engine would run in- a class of it's own, I guess!

Pretty cool concept!

Unh, let's see -- since the sample uses a gaseous fuel -- that'd put it into a fuel class, right?  That is -- ERC (or whomever) doesn't have gaseous fuels at the race tracks and therefore you'd have to supply your own.  And other than that -- well, displacement would be pretty easy to figure -- just measure the length of the "cylinders" and subtract whatever squish room is left at TDC -- after all, the "pistons" come all the way out of the cylinders each time.

And since the pistons come out of the cylinders -- it's be a 2-stroke 'cause the suck and blow parts of the cycle happen without any push or pull from a piston.

Right?

Whatever -- wow, what a mess of stuff going on there, like gear trains turning more gears - to keep the "cylinders" aligned right, and so on. . . :-D

Haha- mess is right! Pretty cool though.

Burns natural gas, gasoline, or diesel fuel. It would be fun to have one to play with, but I imagine a guy would pull his hair out learning to 'tune and time' it! :-D

I wanna see the piston rings.  :wink: Wayno

What a gear train nightmare.
Any backlash in the gears would cause a piston/cylinder miss alignment and BLEWEY!

If you tried to generate any real power, trying to make it rigid enough would be impossible.

If the "propane powered" video were real there would be very loud popping when the piston left the cylinder. I think the "starter" motor was running it.

Anybody notice the lack of spark plugs or fuel lines?

Well, it used to be Los Angeles . . . 50 miles north of Fresno now.

I found it quite erotic, err, exotic.

Does the exhaust and intake air just kind of swirl around togeather or am I missing something?
Maybe with a housing on it a fan would blow fresh air in and push the old out?
Interesting.

While I agree it might be a nightmare to get real power out of, I find it intriguing!

Here's drawing of the ring assembly, and an engine cutaway.

Dean, the plugs are in the pistons (!?)

I was also thinking the same thing with respect to the gear alignment - I suspect the fine tooth gears are intended to minimize lash, but one worn bearing and it's off the smelter.

It's a great concept/exercise, but by the time one engineered it to a durability point where it would make sense for an automotive application, I suspect it wouldn't be any lighter or any more powerful than a reciprocating engine.
