Default Re: Two-smoke fans take note of these guys.

The rotary engine had a different set of problems, I think, in that some of the "rings" had to go through a cycle of contact and release (when they passed through one of the chambers). This engine has constant contact on the ring surfaces, which I think would be easier, and the rings would always be at the same angle of contact with the surface, which is good. It's an amazing concept, actually.

Default 1000 RPM power band?

The ragged torque curve is dropping like a stone below 5000 RPM. I'll bet it won't run at all at 4000.



I'll bet the part of the torque curve they didn't show is both short and hilarious.

While everything is stable, the cylinder is on a curve: metal expansion and radial torque; would heat cause those things; and could either of two things cause damage, or catastrophic failure?

Lotsa heat, lotsa forces, lotsa surface area to bend, twist, warp and expand...Gotta Wonder!
