ャージャ付エンジン。In a turbocharged engine, this valve is installed in the exhaust passage located upstream of the turbine so that it can be opened and closed, and when opened, a portion of the exhaust is routed from the exhaust passage to the atmosphere.The wastegate valve is located downstream of the compressor. A first pressure sensing means is connected to the wastegate valve and is connected to the intake passage through a communication passage, and when the first pressure sensing means senses that the set boost pressure has been reached, the wastegate valve is activated. a first actuator comprising a driving member that operates to open the exhaust passage; a second sensing means for sensing the pressure in the exhaust passage; and a second sensing means for sensing the pressure in the exhaust passage; A turbocharged engine comprising a second actuator having a valve that operates to open the communication passage to the atmosphere when the second pressure sensing means detects a set exhaust pressure that is also high.
