A method is described of controlling the quantity of fuel being supplied to an internal combustion engine after cranking thereof, which is adapted to set an initial value of a fuel increment, which corresponds to the temperature of the engine, upon generation of a predetermined control signal immediately after the cranking of the engine, subsequently decrease the set initial value of the fuel increment at a predetermined rate upon each generation of the predetermined control signal, and supply the engine with a quantity of fuel set by the use of the thus decreased fuel increment, in synchronism with generation of the predetermined control signal. The method consists of: (1) comparing the value of the fuel increment with a predetermined reference value upon each generation of the predetermined control signal, the predetermined reference value assuming a value dependent upon the set initial value of the fuel increment; (2) decreasing the value of the fuel increment at a first rate when it is larger than the predetermined reference value; and (3) decreasing the value of the fuel increment at a second rate which is smaller than the first rate when the value of the fuel increment is smaller than the predetermined reference value.
