To correct all of those that don't know,
the rotary engine is an engine that was thought of by Dr. Felix Wankel when he was 17 and he made the first prototype of this type of engine, but sadly never perfected it (he never got rid of the chatter marks). Once Mazda got a hold of it and started working on it they perfected the engine, getting rid of the chatter marks and adding a second rotor because at low rpms a single rotor became erratic and had torque fluctuations. Also, the rotor is not shaped like a dorito, it's closer to one of those old
3d doritos (if you remember those) because it is an
equilateral triangle with exploded sides.
