Abstract
In the high pressure exhaust gas duct of a pressure wave supercharger, a rotary valve is supported in the region where the gas pocket supply branches off from the high pressure exhaust gas duct, the angular position of the rotary valve being controlled either in steps or steplessly by one or more parameters typical of the pressure wave process and, if necessary, of the engine working process or the engine operating condition. Depending on the operating condition, the rotary valve closes the high pressure exhaust gas duct and the gas pocket supply duct completely or partially. Control is preferably carried out by a step motor with characteristics control by an in-process computer.
