ABSTRACT:
A method of controlling the quantity of fuel supplied to an internal combustion engine after starting thereof. An initial value of a fuel increment is set in response to a temperature of the engine immediately after the start of the engine, and is subsequently decreased with the lapse of time. A quantity of fuel set by the use of the thus decreased fuel increment is supplied to the engine. The rate of decrease of the fuel increment is set to a value corresponding to a sensed temperature representative of fuel injection valves of the engine. Preferably, the rate of decrease is set to a smaller value when the sensed temperature is equal to or higher than a value corresponding to the boiling point of the fuel, than a value set when the former is lower than the latter.
