Why are rotary engines so unreliable?

Due to the long and uniquely-shaped combustion chamber, thermal efficiency of the engine was relatively lower compared to piston-cylinder counterparts. This also often led to unburnt fuel leaving the exhaust (hence the tendency of rotary engines to backfire, which is obviously as awesome as it is inefficient).

  2. Idling or cutting off problems. …
  3. Frequent misfiring. …
  4. Noticeable reduction in power.
