PROBLEM TO BE SOLVED: To provide a fuel injection control device of an internal combustion engine which even when fuel injection from a direct injection type injector is divided into injection of a plurality of times, can ensure fuel injection amount necessary for contributing to combustion improvement in each fuel injection.SOLUTION: An electronic control device to be applied to an internal combustion engine which performs fuel injection from a direct type injector a plurality of times per one combustion cycle of the internal combustion engine, sets the necessary minimum fuel injection amount Qd1min-Qd3min for each fuel injection from the direct injection type injector, sets the respective target fuel injection amounts Qd1-Qd3 on each fuel injection from the direct injection type injector to the requested values according to the engine operating condition, allocates the requested fuel injection amount Qfin to the respective necessary minimum fuel injection amounts Qd1min-Qd3min, and allocates the remaining amount of the requested fuel injection amount Qfin after the allocation to be the target fuel injection amounts Qd1min-Qd3min in this order from the fuel injection of higher priority among the respective fuel injections from the direct injection type injector. |
