A Wankel Rotary Engine in a Nutshell

A rotary powered engine is an engine that uses a rotor instead of a piston. This was made by Mazda in 4 rotor and 6 rotor models and is essentially an engine good for power but nothing else. They are loud and burn oil even when new just by design. They are now dead due to burning oil, advances in piston engine power, and the fact when a rotary engine hits 100 thousand miles, they are shot and need to be rebuilt, thus making them less reliable than even an American car.
