Abstract: A valve throttled internal combustion engine having inlet valve means for each cylinder including a poppet valve and a throttle valve, each of which independently cooperates with the combustion chamber inlet port to control the flow of combustible mixture thereto. The poppet valve actuating mechanism moves it cyclically through a fixed stroke so that it controls the timing of the inlet valve openings while the throttle valve is mechanically actuated by the engine operator to vary the maximum size of the inlet port flow passage and thereby the extent of the inlet valve openings.
