Abstract

Provision is made in the induced air duct and/or in the exhaust duct of the pressure wave supercharger for butterfly valves, by the control of which the exhaust gas proportion to be returned to the charge air is matched to the load condition of the engine. The adjustment of the butterfly valve or butterfly valves occurs through a linkage as a function of the load condition of the engine. A correction link acts on the linkage being provided to compensate for pressure alterations in the induced air duct and/or exhaust duct.
