This patent describes fuel supply control apparatus for an internal combustion engine comprising: an air flow sensor for detecting an air intake quantity which is sucked into the internal combustion engine to be controlled, a revolution sensor which detects the number of revolutions of the internal combustion engine, an AN detecting means for detecting synchronously with each revolution the air intake quantity per each suction of the internal combustion engine on the basis of an output of the air flow sensor and the revolution sensor, an AN computing means for damping an output of the AN detecting means, synchronously with each revolution, a control means for controlling a fuel supply to the internal combustion engine on the basis of an output of the AN computing means, an air intake incremental detecting means for detecting an incremental value of the output of the AN computing means at each damping cycle, a means for increasing fuel supply quantity to the internal combustion engine on the basis of the output of the AN computing means corrected by the incremental value of the output thereof, when the air intake incremental detecting means detects that the incremental value of the output of the AN computing means is larger than a predetermined value.
