ABSTRACT:
A system for controlling the air-fuel ratio of an internal combustion engine includes a transient fuel amount increasing device for regulating the supply fuel amount in the transient state of the engine on the basis of the detection of the transient state of the engine, an air-fuel ratio deviation detecting device for detecting the air-fuel ratio deviation from the optimum air-fuel ratio, and a transient fuel increase amount correcting device for correcting the fuel increase amount in the transient state of the engine in accordance with the air-fuel ratio deviation detected by the air-fuel ratio deviation detecting device. The air-fuel deviation from the optimum air-fuel ratio of the air-fuel mixture upon deposition of a deposit on the back surface of the intake valve is prevented, and the drivability of an automobile is improved.
