Koike, Y; Tsukimura, K

A method is described for controlling the supply of fuel to an internal combustion engine comprising the steps of: (a) determining whether or not the engine is operating in a predetermined low load condition; (b) supplying fuel in an amount responsive to the predetermined low load condition to the cylinders through the first fuel injection valve alone, when the engine is determined to be operating in the predetermined low load condition; and (c) supplying fuel to the cylinders through both the first and second fuel injection valves when the engine is determined to be operating in an operating condition other than the predetermined low load condition in a manner such that (1) the second fuel injection valve supplies a first amount of fuel which is required for the operating condition other than the predetermined low load condition and (2) the first fuel injection valve supplies a second amount of fuel which compensates for a portion of the first amount of fuel supplied by the second injection valve which portion is not immediately and directly supplied to the cylinders.
