過給機付内燃機関。 An exhaust turbine supercharger, a bypass passage that bypasses the exhaust turbine of the supercharger, a waste gate valve that opens and closes the bypass passage according to boost pressure, and a weight gate valve that opens and closes the bypass passage according to boost pressure. In an internal combustion engine with a supercharger, the engine is equipped with an actuator that opens and closes the valve, and an O2 sensor that detects richness or leanness of exhaust gas is installed downstream of the exhaust turbine. An internal combustion engine with a supercharger, characterized in that a clutch means is provided for disconnecting the two in accordance with the temperature, and opens the waste gate valve independently of the actuator when the engine is at low temperature.
