You asked: What is the difference between a 2 cycle and a 4 cycle engine?

For a 4- cycle engine the piston moves up and then down the engine cylinder 4 times to accomplish fuel intake or induction, compression, fuel ignition (combustion) and exhaust. In a 2 Cycle engine this is done in 2 piston strokes (one up and one down the piston cylinder).

Is a 2-cycle or 4-cycle engine better?
