ABSTRACT:
A supercharger control system for the internal combustion engine comprising a supercharger for applying a supercharge pressure to the engine by driving a compressor with a turbine rotated by the energy of the exhaust gas, and an exhaust gas bypass valve for regulating the amount of the exhaust gas supplied to the turbine. A factor related to the engine combustion state such as a knocking condition is detected, and a signal representing the condition is generated. At least one output pressure produced from the compressor is modified in accordance with the above-mentioned signal. The pressure thus modified is used for adjusting the opening of the exhaust gas bypass valve thereby to control the supercharge pressure.
