Abstract
A rotary engine is one of the ancient internal-combustion engines ever used. These type of engines were designed with an odd number of cylinder per row in a radial configuration. The crack shaft remained stationary throughout the operation. One advantage of this kind of engine is that it is a simple engine that utilizes less moving components. On the other hand, a piston engine or a reciprocating engine is a heat engine that uses one or several reciprocating pistons. The piston engine converts pressure into a rotating motion. A piston engine has the capability to seal the gap in ...
