ABSTRACT:
A fuel intake control system for a supercharged engine including an engine driven supercharger comprises a primary intake passage having a primary throttle valve for controlling the flow of an air-fuel mixture to be supplied to the engine, and an auxiliary intake passage having an auxiliary throttle valve for controlling the flow of at least an air supercharged by the supercharger and adapted to be supplied to the engine. The pressure of the discharged air by the supercharger during a particular engine operating condition is adjusted in dependence on the load imposed on the engine in such a way as to increase with increase of the load. This can be accomplished by controlling the flow of a portion of the discharged air to be relieved to the atmosphere or by controlling the rotational speed of the supercharger.
