からなるターボ過給機付エンジン。 Large and small capacity turbochargers are arranged in parallel, and each turbocharger is switched on and off by the on-off switching valve. In engines equipped with large and small capacity turbo superchargers, which enable air supply to match engine conditions such as load range, a switching valve is attached to the partition wall of both the exhaust gas passages of the large and small capacity turbo superchargers. In order to control the switching direction and opening area of the switching valve, a boost pressure take-off pipe is provided to take out boost pressure from each of the large and small capacity turbo superchargers, and a boost pressure take-off pipe is provided in each of the boost pressure take-off pipes. A three-way valve is equipped with a pressure regulating valve leading from the air source.
A turbocharged engine comprising a switching valve operating mechanism attached with an actuator that communicates each of the boost pressure take-off pipes with each diaphragm chamber partitioned by a diaphragm.
