Rotary valve internal combustion engine has valves formed by rotary flow tubes extending across cylinder head

摘要

The rotary valve internal combustion engine has the valve rotors formed as tubes extending across the cylinder head. The tubes rotate in the head and have ports for intake and exhaust gas flows in their sides. The charge and exhaust flows occur along the lengths of the tubes. There can be spaced arrays of ports in the tubes to feed adjacent cylinders in a multiple cylinder engine.
