Claims

[Scope of utility model registration request]

An injection amount setting means that sets the fuel injection amount according to the engine operating state, and an injection start that sets the injection start time so that the injection end time is immediately before the intake valve opens according to the set fuel injection amount. a timing setting means, an acceleration operation state detection means for detecting an acceleration operation state, and correcting the injection end time according to the detected acceleration operation state so that the injection end time is in a valve open period in which the intake valve is open. An electronically controlled fuel injection device for an internal combustion engine, comprising a correction means and a drive control means for driving and controlling a fuel injection valve based on the corrected injection end timing.
