ABSTRACT:
A fuel injection control device (ECU) for controlling injection supply of fuel to a target engine has a program for sequentially sensing fuel pressure fluctuating with injection of a predetermined injector a program for detecting an injection centroid of a diagram as a profile of a transition of an injection rate of the injector at a present time based on a transition of the sequentially sensed fuel pressure, and a program for varying an injection command (injection timing) of the injector based on the detected injection centroid and an injection centroid of a predetermined basic diagram such that a relative positional relationship between the injection centroids of the diagram as the actual profile of the injection rate transition and the basic diagram becomes a relationship, in which timings of the injection centroids are close to each other.
