ABSTRACT:
An engine control apparatus in which an air/fuel ratio for the engine is controlled between the stoichiometric point and a lean point. The engine control apparatus is constructed so as to detect a predetermined period of the transient time in which the air/fuel ratio is switched from the stoichiometric point to the lean point or from the lean point to the stoichiometric point, and delay an ignition timing during the predetermined period of transient time.
