Abstract
An engine fuel supply control system having an air fuel ratio detector which detects the concentration of oxygen content in the engine exhaust gas and providing an air fuel ratio signal representing the air fuel ratio of the engine intake mixture. A control unit is provided to compare the air fuel ratio signal with a reference signal representing a desired air fuel ratio and adjusting the air fuel ratio by a predetermined control factor so that the actual air fuel ratio becomes closer to the desired ratio. The amount of the predetermined control factor is smaller in the engine operating condition wherein the desired air fuel ratio is relatively lean than in the engine operating condition wherein the desired air fuel ratio is relatively rich.
