ABSTRACT:
The air-fuel ratio of an air-fuel mixture to be supplied to a combustion chamber is controlled in accordance with a feedback control mode or a lean control mode. In the feedback control mode, the air-fuel ratio is feedback-controlled to be maintained around the stoichiometric air-fuel ratio. In the lean control mode, the air-fuel ratio is controlled to be maintained at a leaner side of the stoichiometric air-fuel ratio. Ignition plugs are ignited at a first ignition timing which is comparatively advanced in the lean control mode and at a second ignition timing which is behind the first ignition timing in the feedback control mode.
The ignition plugs are ignited at the second ignition timing for a predetermined period of time after switching from the lean control mode to the feedback control mode and at the first ignition timing for a predetermined period of time after switching from the feedback control mode to the lean control mode.
