A multi-cylinder wobble plate engine includes a two-part wobble plate, wherein an inner part is fixedly mounted to an elongate longitudinally aligned main shaft, with an external portion of the wobble plate fixedly mounted relative to a surrounding housing utilizing a stabilizer rod, wherein a plurality of piston rods utilizing swivel bearings are mounted to the periphery of the external wobble plate. Stroke of the engine is determined by angle inclination of the wobble plate relative to the main shaft. An overhead valve assembly is operative through a gear drive in association with a gear mounted on the main shaft to direct actuation of intake in exhaust valves utilized in a conventional four-cycle internal combustion engine. A cam plate utilizing a plurality of pairs of cam plate projections actuates the valves directly and is operative at a one-quarter speed of the main shaft in a reverse direction to that of the main shaft.
