This patent describes a fuel supply control apparatus for an internal combustion engine, comprising: an air flow sensor for detecting a quantity of air sucked into the internal combustion engine; a revolution sensor for measuring a number of revolutions of the internal combustion engine; first detecting means, responsive to the air flow sensor and the revolution sensor, for generating a first value, synchronously with the revolution of the internal combustion engine, indicative of a quantity of air drawn into the engine per one suction; AN computing means, responsive to the first detecting means, fore blurring the first value synchronously with the revolution to produce a blurred value; second detecting means, responsive to the AN computing means, for generating a second value indicative of an amount of decrease in the blurred value and for adjusting the second value to an adjusted second value when the second value is less than predetermined amount; control means, responsive to the AN computing means, for determining a fuel supply quantity based at least in part on the blurred value; and correcting means for correcting the fuel supply quantity based at least in part on the adjusted second value when the second value is less than a predetermined amount.
