摘要：
Problem to be Solved: There will be provided a fuel injection system for an internal combustion engine capable of supplying, in structure in which fuel injection valves are arranged on the upstream side and on the downstream side of the throttle valve respectively, an optimum quantity of fuel to the intake temperature.
Solution: 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, 102, 105) for determining fuel injection quantity of the upstream and downstream fuel injection valves; a sensor (2) for detecting intake temperature (TA) on the upstream side from an injection area of the upstream fuel injection valve; and means (103) for seeking an intake temperature correction factor (KTA) on the basis of the intake temperature (TA) and a fuel injection quantity of the upstream fuel injection valve, wherein there is corrected at least one of the fuel injection quantities due to the upstream and downstream fuel injection valves on the basis of the intake temperature correction factor (KTA).
