Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an engine fuel injection control device capable of suppressing the formation of an excessive fuel concentration region in diffusive combustion. SOLUTION: The fuel injection control device (4) is provided in each cylinder of an engine (2). The device includes an injection nozzle (28) for injecting fuel into a combustion chamber, and a pressure changing device (30) for temporarily reducing the pressure of pressure fuel to be supplied to the injection nozzle (28). An ECU (20) controls the pressure changing device (30) to temporarily reduce the pressure of the pressure fuel to be supplied to the injection nozzle (28) depending on the operating condition of the engine (2) when controlling the injection nozzle (28) to execute the main injection of the fuel, thus temporarily reducing the fuel injection rate of the injection nozzle (28).
