を特徴とする過給機付エンジン。 An exhaust turbo supercharger is provided for supercharging intake air by driving a blower installed in the intake passage by a turbine installed in the exhaust passage, and a bypass passage is provided to bypass the blower or the turbine. A bypass valve for boost pressure control operated by a diaphragm device is installed, and a pressure introduction passage is connected to the pressure chamber of the diaphragm device to open the bypass valve by introducing intake pressure downstream of the blower. In a supercharged engine in which a pressure introduction passage is provided with a control valve that opens and closes in response to a control signal from a control device corresponding to the operating state of the engine to control supercharging pressure to a predetermined value, the control valve is A supercharged engine characterized in that the engine is configured to operate to open a pressure introduction passage when a signal from a control device is not input.
