を特徴とする複合過給装置。 A turbocharger, a wastegate valve that opens in response to the supercharging pressure in the intake passage system, suppresses the rotational speed of the turbocharger, and controls the supercharging pressure generated by the turbocharger below a certain value, and the supercharging that the wastegate valve receives. A valve opening pressure control means for controlling the magnitude of the pressure, a supercharger, a means for stopping the operation of the supercharger depending on the operating state of the engine, and a bypass passage that bypasses the supercharger, and a control valve that opens depending on the operating state of the engine to control the supercharging pressure caused by the supercharger, and the valve opening pressure control means is configured to control when the engine speed increases and the supercharger is stopped. A composite supercharging device characterized in that the supercharging pressure is increased when the waste gate valve is opened.
