ABSTRACT:
A rotary piston engine including a casing having a trochoidal inner surface which defines an elongated cavity therethrough. Opposed end walls close said cavity, and a rotary pistion is journalled therein to be driven in a planetary movement, thereby rotating a drive shaft. Apices formed intermediate peripheral piston faces, slidably contact the trochoidal surface during the engine intake, compression and combustion periods. Each of said piston faces is provided with a shaped compound depression comprised in part of a first cavity in which an air-fuel charge is formed, compressed, and ignited. The resulting flame passes into a second or main portion of the compound cavity to ignite the major portion of the charge and complete the combustion phase.
