In a fuel injection system for an internal combustion engine in which fuel injection valves are arranged on the upstream side and on the downstream side of the throttle valve respectively, the throttle valve will be prevented from freezing without involving addition of piping and the like. A fuel injection system for an internal combustion engine, having an upstream fuel injection valve provided upstream from the throttle valve and a downstream fuel injection valve provided downstream therefrom, including: means 101 for determining the total injection quantity of each fuel injection valve; means 102 for determining a rate of fuel injection quantity due to each fuel injection valve; means 2, 3 for acquiring temperature information representing the throttle valve temperature; and means 103 for correcting the rate on the basis of the temperature information, characterized in that the correction means 103 decreases the injection rate of the upstream fuel injection valve when the throttle valve is at low temperature.
