A method of controlling the supply of fuel to an internal combustion engine is described, consisting of: (a) detecting a temperature of the engine; (b) detecting the degree of opening of the throttle valve; (c) comparing the detected temperature of the engine with a predetermined value; (d) comparing the detected degree of opening of the throttle valve with a predetermined value; (e) operating the second fuel injection valve to supply fuel to the cylinders irrespective of the detected degree of opening of the throttle valve when the detected temperature of the engine is lower than the predetermined value; and (f) operating the first fuel injection valve to supply fuel to the cylinders when the detected temperature is higher than the predetermined value and at the same time the detected degree of opening of the throttle valve is smaller than the predetermined value.
