ABSTRACT:
An air-fuel ratio feedback control system is provided with a section for producing a desired air-fuel ratio dependent on engine operating conditions and with an inherent time delay calculator for producing a time delay signal. The change of the desired air-fuel ratio dependent on the change of the engine operating conditions is delayed for a period dependent on the time delay signal.
