ABSTRACT:
An internal combustion engine includes an engine block having one or more cylinders and a rotary disk valve mounted on top of the engine block. The rotary disk valve includes an intake passage for directing intake air into the cylinders and an exhaust passage for exhausting combustion gases from the cylinder. The center of the intake passage and exhaust passage are equidistant from the axis of rotation of the rotary valve. The intake passage and exhaust passage in the rotary valve communicate with each cylinder in succession as the valve rotates, allowing the use of a single valve to serve multiple cylinders. Both the intake passage and exhaust passage have a cross sectional area at its narrowest point equal to at least 40% of the cross sectional area of the cylinders.
