PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine in which if a split ratio of split fuel injection amounts deviates from a request range, deterioration of a combustion state can be suppressed more than in a conventional one, the internal combustion engine allowing a direct-injection injector to perform split injection.SOLUTION: A fuel injection control device is for an internal combustion engine, and the internal combustion engine has cylinders and direct-injection injectors capable of injecting fuel into the cylinders, and can switch an injection method of the direct-injection injector into one of a single injection and split injection. When the injection method is the split injection (step S4; YES), and the split ratio at which a direct-injection total injection amount is split into split injection amounts deviates from a range of a predetermined guard ratio (step S11; NO), the injection method is switched to the single injection (step S14). |
