ABSTRACT:
In an electronic fuel supply control system for an internal combustion engines, the fuel quantity being supplied to the engine is set to different values in accordance with the operating condition of the engine, between when the exhaust gas recirculation is operated and when it is not operated, for achieving proper air/fuel ratios. Further, immediately after a valve lift command is outputted at full closing of the exhaust gas recirculation valve, which is indicative of opening of the valve, a quantity of fuel set as applicable when the exhaust gas recirculation is not operated is supplied to the engine until the actual valve opening increases to a predetermined value. Immediately after a valve lift command is outputted at opening of the valve, which is indicative of full closing of the valve, a quantity of fuel set as applicable when the exhaust gas recirculation is operated is supplied to the engine until the actual valve opening decreases to a predetermined value. Thus a response lag of the exhaust gas recirculation valve is compensated for.
