A [[rotary engine]] would do the same task as reciprocating engine but in a very different manner due to its triangular rotor.

The four-stroke cycle is what gives the engine its energy, but now it must translate this energy into [[rotational energy]] for the [[transmission (vehicle)|transmission]], [[drive shaft]] and wheels. This is done by the [[crankshaft]], which is seen in Figure 1. The crankshaft converts this up-and-down motion into rotational motion, which is often combined with a flywheel to retain the discontinuous reciprocating energy as rotational energy.
