    摘要： A multistage supercharging system for a reciprocating engine, which is suitable for use in an aircraft capable of flying at high altitude, includes plural stage turbochargers connected in series to each other. A control unit controls operation of these turbochargers. The turbocharger at each stage includes a turbine side bypass passage bypassing the turbine, a compressor side bypass passage bypassing the compressor, a wastegate valve for controlling the flow rate of exhaust flowing through the turbine side bypass passage, a bleed valve for controlling the flow rate of intake air flowing through the compressor side bypass passage, and a pressure sensor disposed at the downstream side of the compressor. The control unit receives a signal from the pressure sensor, and controls the respective valves to selectively operate the turbochargers.

    摘要： An engine control apparatus controls a throttle valve opening degree in response to a demand output of a driver. A target charged intake air amount of air taken into a cylinder per intake stroke is set in response to the demand output. Based on an air pressure generated at an upstream side of a throttle valve, the maximum actual charged intake air amount is set as a maximum value of the actual charged intake air amount taken into the cylinder per intake stroke. The target charged intake air amount is normalized by calculating a ratio of the target charged intake air amount to the maximum actual intake air amount. The throttle valve opening degree is set based on the normalized target charged intake air amount and an engine speed. Then, a signal for actuating the throttle valve is output to a throttle actuator so that the throttle valve has the set opening degree. Fuel injection amount is set based on the target charged intake air amount.
