Method of controlling fuel supply for internal combustion engine at idle
A method of controlling the quantity of fuel to be supplied to an internal combustion engine while its operating in an idling condition is described, wherein the fuel quantity is determined in accordance with operating conditions of the engine in the idling condition. The determined fuel quantity is corrected by a correction value which is determined in response to the difference between a desired idling value of the rotational speed of the engine and an actual value thereof. The method consists of: (1) detecting whether the rotational speed of the engine is varying toward a predetermined value or away from same; (2) correcting the correction value to a smaller value when the rotational speed of the engine is detected to be varying toward the predetermined value; and (3) correcting the determined fuel quantity by the correction value thus corrected.
