ABSTRACT:
In an air-fuel ratio control system for an internal combustion engine, a proportional part for determining a feedback correction factor is corrected by a value proportional to an intake air flow corresponding value, whereas an integral part for determining the feedback correction factor is corrected by a value proportional to a square of the intake air flow corresponding value.
