摘要： A fuel injection control system is provided. The fuel injection control system comprises a first injector and a second injector positioned upstream of the first injector; a memory section which contains a map for defining a correspondence between a running state of an engine and first and second fuel injection ratios; a fuel injection ratio setting section for setting the first fuel injection ratio as a first set value and the second fuel injection ratio as a second set value; and a fuel injection ratio compensation section for making compensation such that the first set value is greater than a value of the first fuel injection ratio derived from the map, when a condition in which the second fuel injection ratio read out from the map is greater in magnitude than a predetermined determination criterion is met.
