Fujimura, A; Wazaki, Y

This patent describes a method of controlling the supply of fuel to an internal combustion engine having an intake system after starting, wherein an initial value of a fuel increment is set to a value dependent upon a temperature of the engine after starting thereof, the fuel increment is progressively decreased from the set initial value thereof at a predetermined rate, and a fuel quantity corrected by the progressively decreased fuel increment is supplied to the engine. The method consists the steps of: (a) sensing a temperature of the intake system of the engine; and (b) setting the predetermined rate at which the fuel increment is progressively decreased to a larger value as the sensed temperature of the intake system is higher.
