ABSTRACT:
A fuel supply control method for an internal combustion engine, which supplies fuel to the engine in quantities appropriate to operating conditions thereof in synchronism with generation of pulses of a predetermined control signal. A plurality of groups of predetermined correction values for increasing the quantity of fuel to be supplied to the engine at acceleration thereof are set beforehand, which are functions of at least two operating parameters of the engine. When the engine is determined to be operating in a predetermined accelerating condition for the first time, values of the above at least two operating parameters are detected upon the same determination being obtained. One of the groups of predetermined correction values is selected, which corresponds to the detected values of the at least two operating parameters. Then, different ones of the predetermined correction values of the selected one group are successively applied for correction of the quantity of fuel being supplied to the engine, with passage of time after the above determination is obtained for the first time and as long as the engine is determined to be operating in the predetermined accelerating condition.
