ABSTRACT:
A rotary valve internal combustion engine comprising a crankshaft, a throttle (23), a throttle actuator, a cylinder head (7), a combustion chamber (8), and at least one rotary valve (1). The rotary valve (1) having at least two ports (2, 3) terminating as openings (4, 5) in its periphery, the cylinder head (7) having a bore (11) in which the rotary valve (1) rotates, a window (6) in the bore (11) communicating with the combustion chamber (8), the openings (4, 5) successively aligning with the window (6) by virtue of the rotation, a drive mechanism comprising a phase change means (18), the drive mechanism driving the rotary valve (1). The at least two ports (2, 3) comprise an inlet port (2) and an exhaust port (3), and the phase change means (18) applies a phase change in response to changes in the operating conditions of the engine over at least one engine cycle.
