Why is the rotary engine bad?
Rotary engines have a low thermal efficiency as a result of a long combustion chamber and unburnt fuel making it to the exhaust. They also have problems with rotor sealing as a result of uneven temperatures in the combustion chamber since combustion only occurs in one portion of the engine.
What car has the 20B engine?
Mazda 13G. Mazda introduced their first 3-rotor engine to the public in 1984, found in the Mazda 757 Le Mans racer. Utilizing the rotary’s design, Mazda opted to stack multiple 13B housings, giving birth to the idea for both the 3-rotor (13G, 20B) and four-rotor (26B) engines.
