A two-cycle, reciprocal piston, rotary combustion engine is provided including an outer casing, a housing disposed within and journaled from the casing about a central longitudinal axis with the housing including a plurality of parallel circularly arranged elongated cylinders spaced about the casing longitudinal axis. A pair of pistons are inversely reciprocal in each of the cylinders and the opposite ends of the casing includes stationary circular cam ramps with which rollers journaled from the remote ends of the pistons are rollingly engaged, the cam ramps and roller peripheries being inclined relative to a plane normal to the casing longitudinal axis an amount which enables the roller peripheries to rollingly contact the cam ramps substantially independent of any sliding contact between the contacting surfaces of the rollers and cam ramps, each of the longitudinal central portions of the cylinders including a single ingress and egress port opening outwardly therefrom away from the longitudinal axis of the casing successively registerable with ignition structure and combustion gas exhaust and air intake ports spaced about the casing periphery.
