Abstract
An air-fuel ratio control apparatus for an internal combustion engine controls a fuel supplying means by a signal generated from an air-fuel sensor so that the air-fuel ratio of a gas mixture to be sucked into the internal combustion engine becoms a target air-fuel ratio. The air-fuel ratio control apparatus corrects the target air-fuel ratio by a parameter on the condition of the engine detected by the detecting means so that a fuel supplying device is controlled to obtain a corrected target air-fuel ratio.
