ABSTRACT:
A fuel injection control device (ECU) for controlling injection supply of fuel to a target engine includes a program for sequentially sensing fuel pressure fluctuating with injection of a predetermined injector of each cylinder of a multi-cylinder engine based on an output of a fuel pressure sensor, a program for detecting a diagram as a profile of a transition of a fuel quantity injected from the injector per unit time (i.e., an injection rate) at a present time based on the sequentially sensed fuel pressure transition, and a program for varying an injection command to the injector based on the diagram that is the profile of the injection rate transition and that is detected by the latter program and a predetermined basic diagram such that the diagram as the actual profile of the injection rate transition belongs to the basic diagram.
