Claims

[Claims of Utility Model Registration] A turbocharger compressor compresses intake air and supplies it to the engine, and also supplies boost pressure to an actuator, and when the boost pressure exceeds a predetermined value, the actuator is activated. In an engine in which a wastegate valve is opened to discharge part of the exhaust gas without passing through the turbine of the turbocharger, a solenoid valve is provided in a conduit that supplies boost pressure to the actuator, and this solenoid valve is provided. A turbocharged engine characterized in that opening and closing of the engine is controlled by an electronic control device according to the state of the engine.
