Zusammenfassung:In an arrangement for controlling the charging air flow of a supercharged internal combustion engine which has an intake air pipe with a throttle valve connected to the discharge side of a supercharger and a communication pipe extending from the intake air pipe to the engine exhaust manifold for supplying air to the engine exhaust gas, an air supply pipe extends from an air filter housing to the supercharger suction side and a return air duct including a flow control valve extends from the intake air pipe to the air filter housing for recirculating air to the supercharger suction side through the air filter housing under the control of the flow control valve for controlling the air pressure in the engine intake air pipe.
