ABSTRACT:
In a constitution for feedback controlling an air-fuel ratio using an oxygen concentration detector in which a detection signal thereof has a linearity to the air-fuel ratio within a predetermined air-fuel ratio range inclusive of a stoichiometric air-fuel ratio, when the detection signal from the oxygen concentration detector is outside a region indicating the linearity, a change in air-fuel ratio feedback control signal is limited to be smaller than that when the detection signal from the oxygen concentration detector is within the region indicating the linearity.
