ABSTRACT:
In a supercharger for an internal combustion engine having a waste gate valve, a signal for controlling the opening of the waste gate valve is generated in such a manner that a basic amount thereof is produced on the basis of the opening of a throttle valve and the number of revolutions of the engine and then the basic amount is so corrected that an actual mass flow rate of intake air follows a desired value thereof determined by the opening of the throttle valve and the number of revolutions of the engine at that time. According to this, a temperature sensor exclusively used for the controlling the waste gate can be omitted.
