ABSTRACT:
A rotary valve internal combustion engine including a cylinder block having a cylindrical recess, a cylindrical bore transverse to the cylindrical recess, an exhaust passageway leading from the cylindrical bore, and an intake passageway leading to the cylindrical bore. A cylindrical piston sealably reciprocates in the cylindrical recess so that the space defined by the top of the piston and the walls of the cylindrical recess forms a combustion chamber. An arcuate passageway in the block extends between the cylindrical bore and the combustion chamber. A crankshaft is connected to the piston. An ignition system is in communication with the combustion chamber. A carburetor to provide a fuel-air mixture is in communication with the intake passageway. A cylindrical valve, rotatably received in the cylindrical bore, has a hollow body, open ends, two axially aligned intake ports near one end of the cylindrical body, two axially aligned exhaust ports near the opposite end of the cylindrical body, four axially aligned arcuate center openings located between the exhaust ports and the intake ports, and four internal tubes, each tube connecting a center opening with an intake or exhaust port. A sprocket wheel extends from one end of the cylindrical valve and is connected to the crankshaft by a tooth belt. The reciprocating piston rotates the valve to first allow the fuel-air mixture to enter the combustion chamber and then allow burnt gases to be expelled from the combustion chamber.
