過給機付きエンジン。A main exhaust supercharger consisting of a turbine installed in the exhaust passage of the primary intake and exhaust system of the engine, and a lamp-reducer installed in the intake passage of the primary intake and exhaust system to be driven by the turbine. , a sub-exhaust supercharging system consisting of a turbine installed in the exhaust passage of the secondary intake/exhaust system of the engine and a compressor installed in the intake passage of the secondary intake/exhaust system to be driven by the turbine; an exhaust throttle valve installed in the exhaust passage of the secondary intake/exhaust system to control the flow rate of exhaust gas supplied to the turbine of the auxiliary exhaust supercharger; a supercharged air throttle valve that is installed in the intake passage and controls the flow rate of supercharged air sent from the compressor of the sub-exhaust supercharger, and that adjusts the opening degree of the exhaust throttle valve; a supercharging throttle valve actuator that adjusts the opening degree of the supercharging throttle valve, and a control device that supplies control signals to the exhaust throttle valve actuator and the supercharging throttle valve actuator. A cooler is interposed in each of the intake passage of the primary intake and exhaust system and the intake passage of the secondary intake and exhaust system, and the intake passage of the primary intake and exhaust system is provided with a cooler over the entire operating range of the engine. The primary intake valve is operated by the main intake valve, and the intake air is sent to the combustion chamber. A primary intake port for generating a swirl that generates a large swirl is provided, and a J2 freezing intake valve with a valve operation stop mechanism that operates in a partial operating range of the engine is provided in the intake passage of the secondary intake and exhaust system. An engine equipped with an exhaust supercharger, characterized in that a secondary suction port for reducing swirl is provided to reduce the swirl of intake air sent to the combustion chamber.
