ABSTRACT:
An internal combustion engine is provided having a housing with a pair of crankshafts rotatably mounted within the housing in a spaced and parallel relationship. One or more throughbores, forming the cylinder for the engine, are provided in the housing between the crankshafts and slidably receive a pair of piston members therein and in a facing relationship, the piston members being connected to their respective crankshafts by connecting rods in the usual manner. A fuel inlet passageway is provided in the housing to supply a fuel air mixture to each cylinder and between the piston members while, similarly, an exhaust passage is provided in the housing to permit the exhaust fumes to be expelled from each cylinder. An inlet rotary valve is positioned within the inlet passageway and includes at least one diametric throughport for selectively opening and closing the inlet passageway in dependence upon the rotational position of the inlet valve. Similarly, an exhaust rotary valve having at least one diametric throughport is positioned within the exhaust passageway in dependence upon the rotational position of the exhaust valve. Both the inlet and exhaust rotary valves are rotatably driven in synchronism with the reciprocation of the piston members within the housing throughbore.
