Abstract
A power control system for a supercharged internal combustion engine. The system has a passage providing a communication between the compressor outlet of the supercharger and an exhaust by-pass valve actuator, the passage being communicated at its other end with the compressor inlet of the supercharger. A variable orifice valve is disposed at an intermediate portion of the passage opening to the exhaust by-pass valve actuator and the compressor inlet. Control means is provided to control the opening of the variable orifice valve in accordance with the amount of depression of the accelerator pedal of the vehicle or the opening of the throttle valve of the engine.
