A Rotary engine of extreme perfection which has been tested to speeds in excess of 18000 rpm
the main component is a triangular driver, with three hardened rounded tips which rotate against a stater type outer cylinder.
Masda have the monopoly on them and use them on the RX range.
Earlier engines suffered from burnt out tips.
My new Mazda RX8 will eat your Porsche for breakfast then spit it back out because it will have discovered that it had just eaten a jumped up VW beetle that Hitler commissioned...eeeegh!
oooh i love my wankel.
ReCorrection: Felix Wankel invented A PISTONLESS ROTARY ENGINE, now known as the Wankel engine. It is a perfection of the original rotary engines, mainly used in airplanes. He did not invent the rotary engine, the same way that the Kimberly-Clark corporation (makers of the Kleenex) did not invent blowing your nose into something.
An ingenious engine design which avoids the reciprocal motion of the piston engine and manages to incorporate the suck, squeeze, bang, blow of internal combustion engines into a rotating piston.
Not a torture device of any kind.
The Wankel rotary engine is far more efficient than the latest hybrid cars, but nobody will buy one because it sounds too much like "wanker".
