This device for controlling the fuel injection of an internal combustion engine (11) with the cylinder injection of fuel is provided with a fuel injection valve (21) for directly injecting fuel into a cylinder of the internal combustion engine (11), and an injection control unit (30) for dividing the required injection amount of fuel from the fuel injection valve (21) into a plurality of portions and injecting the fuel into the cylinder in a divided manner. In this device for controlling the fuel injection, the injection control unit (30) allows injection to be performed during divided injection even when the injection interval of divided injection is less than the lower limit (Tb - ∆T) of a predetermined range (Tb ± ∆T) in which the injection amount of the fuel injection valve (21) undergoes considerable fluctuations. |
