Abstract
A rotary piston engine having a rotor with an output shaft and a plurality of longitudinally extending cylinder-forming bores, each having a slidable piston disposed therein. The rotor is contained in a housing that contains an elliptical cam track that interacts with the pistons, upon combustion, to cause rotation of the rotor. An opening in the housing end cap admits air into the cylinders on the rear side of the pistons and a port delivers air driven by the rear side of the pistons to an intake port in the side of the housing where, in response to the angular position of the rotor, the air is admitted to the front side of a piston for compression with injected fuel. The compressed fuel-air mixture is ignited and an exhaust port in the side of the housing opens to discharge the products of combustion.
