摘要： A supercharged internal combustion engine has a turbo supercharger mounted on an exhaust pipe so that a turbine of the supercharger is driven by engine exhaust gases to drive a blower for the compression of engine intake air. A bypass exhaust pipe is connected to the exhaust pipe at a point upstream of the supercharger and extends in bypassing relationship to the supercharger. A valve is provided in the exhaust system at the above-mentioned point to control the exhaust gas flow into and through the exhaust pipe and the bypass exhaust pipe, respectively. A valve actuator is responsive to variation in the intake pressure in the engine intake system downstream of a throttle valve to actuate the valve such that, when the intake pressure is not greater than a first predetermined value, the valve is actuated to fully close the exhaust pipe and, when the intake pressure becomes greater than a second predetermined value, the valve is actuated to fully close the bypass pipe, whereby the supercharger is operated only in a throttle full-open engine operating range and the supercharging air pressure is kept below a predetermined pressure level to prevent not only the supercharger but also the engine intake and exhaust systems from being continuously subjected to loads.
