FUEL INJECTION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

In order to eliminate noise generated by misfiring when the rotational frequency rises to the operating rotational frequency immediately after a low-temperature startup, or when the rotational frequency rises to the operating rotational frequency from an idling rotational frequency in a low-temperature state, a fuel injection control device for an internal combustion engine is equipped with: a fuel injection device that is capable of multi-stage injection of fuel (accumulated in a common rail (6)) by means of injectors (2); a cooling water temperature sensor (26) serving as a water temperature detection means that detects the temperature of cooling water in the engine (1); an exhaust temperature sensor (24) serving as an exhaust temperature detection means that detects the exhaust temperature of the engine (1); and an engine control unit (13) serving as a control device. When the engine starts up and the cooling water temperature is equal to or greater than a prescribed water temperature (T) degrees, the control device executes a misfire prevention mode whereby a multi-stage injection is continued.
