料噴射装置。 An internal combustion engine in which each cylinder is provided with a fuel injection valve that is driven and controlled by an injection pulse signal, and each fuel injection valve injects fuel so that the injection end timing is at a predetermined timing for the corresponding cylinder. In an electronically controlled fuel injection device, an engine operating state means detects an engine operating state, a fuel injection amount setting means sets a fuel injection amount based on the engine operating state, and a fuel injection amount setting means sets a fuel injection amount based on an increase in the set fuel injection amount. A fuel pressure variable means for increasing the pressure of the fuel fed to the injection valve; and an injection pulse for setting an injection pulse signal according to the variation of the fuel pressure and outputting it to the fuel injection valve so as to obtain a set fuel injection amount. a signal output means;
An electronically controlled fuel injection device for an internal combustion engine, characterized by comprising:
