ABSTRACT:
A supercharged internal combustion engine is equipped with a supercharging device, a knock sensor and a rotary valve disposed upstream of an intake part of the engine. A Miller cycle is applied to the engine, and when an engine knock occurs, such a phenomenon is sensed by the knock sensor to be converted into an electric signal by which a control device for the rotary valve is operable to stop the charge feed to the engine for a short period of time prior to the completion of the control stroke of the engine, thereby extremely enhancing the output power of the engine while eliminating the generation of the engine knock.
