噴射装置。 a fuel injection valve drive control means that drives and controls a fuel injection valve installed in each cylinder in accordance with an injection pulse signal; and an engine operating state that detects an engine operating state that includes at least a parameter related to the intake air flow rate of the engine. a detection means, a first injection pulse signal output means for outputting the injection pulse signal at a predetermined number of times per unit engine rotation speed, and a change rate of the intake air flow rate based on the parameter detected by the engine operating state detection means. The intake air flow rate change rate detection means detects the rate of change in the intake air flow rate, and when the rate of change in the intake air flow rate detected by the intake air flow rate change rate detection unit is on the increasing side and exceeds a predetermined value, priority is given to the first injection pulse signal output means. a second injection pulse signal output means for outputting an injection pulse signal with a number of injections per unit engine speed greater than the number of injections per unit engine speed by the first injection pulse signal output means; and the first and second injection pulse signal output means. An electronically controlled fuel injection device for an internal combustion engine, comprising injection pulse width setting means for setting the pulse width of an injection pulse signal at minute intervals according to the engine operating state detected by the engine operating state detecting means.
