Quasiturbine engine

We've all driven piston internal combustion engines, right?

I've driven a Mazda RX-4 with a less common engine type, a wankel rotary engine.

One of the things that prevents a standard piston engine from revving harder is that the pistons have to accelerate and decelerate with every stroke. The momentum of the pistons is a major limiting factor. A rotary engine removes this limit by having all moving parts spinning, no acceleration and deceleration required. I can tell you, those engines rev like mad! The main downside of a rotary is that it doesn't completely burn the fuel, so it's not as clean.

Also, each piston only produces a power stroke once for every 2 revolutions of the driveshaft.

Welcome to the next step in this evolution, the Quasiturbine engine. It is far more efficient (it produces 4 power strokes for every revolution of the driveshaft! 8 times more than piston combustion engines) and burns the fuel more completely.

Can't wait until this is in a car... it will be fun to drive.
