Abstract
A cylinder head for an engine has an intake valve chamber and an exhaust valve chamber. Each of the chambers is of elongated cylindrical configuration. Valve ports providing fluid communication between respective valve chambers and the engine cylinder and an intake port and exhaust port providing fluid communication between a respective valve chamber and a respective intake or exhaust manifold. A rotary valve element is used. It is of elongated cylindrical configuration coaxially disposed in each of the valve chambers. Each rotary valve element has a cylindrical tube mounted on a respective rotatable drive shaft journalled in the cylinder head and having an open end in fluid communication with either the respective intake or exhaust port and an aperture formed in a cylindrical wall.
