In a fuel supply control method of an automobile engine wherein a plurality of parameters representing an operating condition of the engine are measured, and a fuel supply quantity is determined based on the measured values so as to attain a target air-fuel ratio, an amount of air flowing into each cylinder in an n-th stroke (n is an arbitrary integer) is calculated for prediction by using the measured parameters in a stroke preceding the n-th stroke, and the fuel supply quantity is determined by the predicted value of the amount of air in the n-th stroke and a target value of the air-fuel ratio in the n-th stroke.
