摘要： A supercharged internal combustion engine is provided with a turbo supercharger mounted on an intake pipe and driven by engine exhaust gases to produce a pressurized intake air to be fed into the engine. A bypass intake pipe branches out of the intake pipe upstream of the supercharger and merges into the intake pipe at a point downstream of the supercharger. A first valve member is disposed in the intake pipe adjacent to the merging point to control the communication between the intake pipe and the bypass intake pipe and the communication between the upstream part of the intake pipe and the downstream part of the intake pipe. A first and second air release ports are formed in the intake pipe, one of which is disposed between the supercharger and the merging point and the other is disposed downstream of the merging point. Second and third valve members are provided to open and close the first and second air release ports, respectively. The first and second valve members are pneumatically actuated in accordance with the variation in the engine intake manifold pressure, whereas the third valve member is moved to its open position when the pressure in the intake pipe downstream of the merging point exceeds a predetermined level.

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.
