Rotary internal combustion engine
A rotary engine for two cycle operation is described having arcurate combustion chambers formed in a rotor and correspondingly arcuate pistons mounted for swinging reciprocation in the combustion chambers on connecting rods pivoted to the rotor. The housing contains the rotor and provides an oblong inner periphery forming a raceway for cam followers mounted on the pistons so that, when ignition of the fuel mixture occurs at the beginning of a power stroke, the pistons are forced outwardly against the relative incline of the raceway in such a manner as to cause the pistons to impart rotary motion to the rotor. At about the end of the power stroke, the movement of the rotor causes recesses formed in the rotor at the inner end of the combustion chamber to communicate with exhaust and intake ports formed in the housing on opposite sides of the rotor for venting the spent gases through one of the recesses and receiving a fresh charge of fuel mixture under pressure through the other recess in a scavenging fashion. The momentum of the rotor tends to cause it to rotate through the compression cycle wherein the cam followers riding on the raceway force the pistons into the combustion chambers to compress the air--gas mixture for ignition at approximately the innermost retracted position and thus initiate the next power stroke.
