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 that enable supply air to match engine conditions such as load ranges, these turbo overcharges occur because the large and small capacity turbo superchargers operate together in high speed and high load ranges. The switching direction and opening area are controlled according to the pressure difference between the boost pressures of the charger's compressor, and the switching valve operates so that the boost pressures of the large and small capacity turbochargers are balanced. An engine with a turbo supercharger, characterized in that the turbocharger is attached to both exhaust gas passage partition walls on the turbine side from the on/off switching valve of the feeder.
