二段ターボエンジンのバイパス弁制御装置。 A low-pressure stage and a high-pressure stage compressor are arranged in series in the intake passage, respectively, and a low-pressure stage and a high-pressure stage turbocharger are provided in which the low-pressure stage and high-pressure stage turbines correspond to the exhaust passage, and the high-pressure stage exhaust bypass passage bypasses the high-pressure stage turbine. An exhaust bypass valve is provided, and an intake bypass valve that fully opens after the exhaust bypass valve is fully opened is provided in the high-pressure intake bypass passage that bypasses the high-pressure compressor, and the exhaust and intake bypass valves are closed in this order during a predetermined engine operating state. A bypass valve control device for a two-stage turbo engine, characterized in that by fully opening the valve, the two-stage supercharging by the low-pressure stage and high-pressure stage turbochargers is substantially switched to the one-stage supercharging by the low-pressure stage turbocharger. .
