Crazy Engines

[Kooldino]

Interesting stuff. I wish they explained how they worked better than they do, but I guess they will in time.

just ad an H to the acronym

What am I missing?
I don't see how it exerts any torque on the output shaft at all.

[Dr Mordrid]

VERY interesting, but disconcerting that it hasn't been tried with fuel yet.

Wonder how the seals hold up given their angles?

It says it has been run with diesel, and implies that's how they dynoed it.

I would guess that they have some kind of ratcheting contraption to keep the trailing bit from rotating backwards. Therefore the leading one must go forwards. They don't make that very obvious though.

How wouldn't it? It spins around a central point...there's your torque.

[ZokesPro]

Bizarre. I'd like to se it in action live. It's quite interesting and looks to have some potential.

Picture a normal piston engine, but with a fourth dimentional mechanical connection between the cylinder head and the crankshaft.
It is not obvous to me how this thing produces torque.

The secret appears to be in the left side parts of these diagrams.
But I don't get it.

[Kooldino]

Still not clear on what you're getting at...

I mean, you have the output shaft, and the piston are spinning around that, thus producing torque. As long a the "pistons" are connected to the output shaft in some manner, you have your twist.

[cjolley]

But why are they going around instead of just flapping back and forth?
And/or why don't the two set of pistons just work at cross purposes?

[Wombat]

But why are they only spinning in one direction? Why doesn't the combustion knock the walls in the other direction?

[Kooldino]

It probably has some kind of ratchet like device in it, allowing it to only turn one way.

[ZokesPro]

But why are they only spinning in one direction? Why doesn't the combustion knock the walls in the other direction?

I would imagine that it depends on which direction you started it first? Not sure though. Then it would keep on turning that way like a regualr combustion engine. But there's nothing that's stopping a regular combustion engine from spinning in the opposite diretion, is there?
