ジン。 A turbine provided in the exhaust pipe of the engine, a compressor coaxially connected to the turbine and provided in the intake pipe, and a bypass passage communicating from the exhaust pipe between the engine and the turbine to the exhaust pipe downstream of the turbine. A turbocharged engine comprising: a wastegate that opens and closes this bypass passage; an exhaust brake provided between the turbine and an exhaust pipe opening on the downstream side of the bypass passage; and a computer that controls opening and closing of the wastegate. A turbocharged engine, characterized in that the wastegate opens only when the load and rotational speed of the engine are within the wastegate opening range and an exhaust brake is not operating.
