Abstract
An air supply control system for an internal combustion engine comprises a supercharging device provided for supercharging the engine and operative to work with supercharging capacity varying in accordance with operating condition of the engine, an engine speed detector for detecting speed of the engine, a shifting-up detector for detecting a shifting-up operation performed in a transmission coupled with the engine, a supercharging capacity changing arrangement operative to vary the supercharging capacity of the supercharging device to be reduced when the speed of the engine detected by the engine speed detector is relatively low and to be increased when the speed of the engine detected by the engine speed detector is relatively high, and supercharging capacity change controller for restraining the supercharging capacity changing arrangement from varying the supercharging capacity of the supercharging device to be reduced when the shifting-up operation is detected by the shifting-up detector.
