Abstract
According to an air-fuel ratio control method, an amount of fuel supplied to an internal combustion engine is calculated by the use of an air-fuel ratio correction coefficient set according to an output from an exhaust gas ingredient concentration sensor. An average value of the air-fuel ratio correction coefficient is calculated. When a difference between an actual value of opening of an exhaust gas recirculation control valve and a desired value of same set in response to operating conditions of the engine is larger than a predetermined value, the calculation of the average value of the air-fuel ratio correction coefficient is inhibited, or alternatively, an averaging rate in the calculation of the average value is decreased.
