Are rotary engines more reliable?

Why are rotary engines so unreliable?

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.

Are rotary engines really unreliable?

No, it’s not just one part of the engine, it’s the whole thing, as the Renesis 1.3-liter rotary engine that powers this sports car is known to be a gas-guzzling, unreliable machine. Instead of pistons, the rotary engine uses rotors to operate, and over time, they tend to wear down.
