Abstract
An internal combustion engine of a lean burn type, wherein the air-fuel ratio is feedback controlled to a predetermined fixed value which is higher than a theoretical air-fuel ratio. The ignition timing is changed when the air-fuel ratio as detected by a lean sensor is off from the target air-fuel ratio, enabling quick control of the engine when the air-fuel ratio is off from the target air fuel ratio.
