This patent describes a method of controlling the quantity of fuel being supplied to an internal combustion engine having fuel injection valves after starting thereof, which is adapted to set an initial value of a fuel increment in response to a temperature of the engine immediately after the start of the engine, subsequently decrease the fuel increment from the set initial value thereof with the lapse of time, supply the engine with a quantity of fuel set by the use of the thus decreased fuel increment, the method comprising the steps of (a) sensing intake air temperature in the vicinity of the fuel injection valves; and (b) setting a rate at which the fuel increment is decreased, to a value corresponding to the sensed intake air temperature.
