ABSTRACT:
The idling engine speed is controlled to a target value at a high response speed with high accuracy even during the control of the air/fuel ratio by correcting the ignition time which is effected by obtaining the concentration of oxygen and calculating an air/fuel ratio correction value of fuel based on the concentration of oxygen during idling and the control of the air/fuel ratio.
