噴射装置。[Scope of Claim for Utility Model Registration] Racing detection that detects the racing state of an engine in an electronically controlled fuel injection system for an internal combustion engine that calculates the fuel injection amount from the intake air flow rate detected by an air flow meter and the engine speed. an intake air flow rate calculation means for calculating an intake air flow rate from the engine rotation speed and a predetermined charging efficiency during racing; and an intake air flow rate calculated from the engine rotation speed and charging efficiency during racing and the intake air detected by an air flow meter. 1. An electronically controlled fuel injection device for an internal combustion engine, comprising a fuel injection amount correction means for correcting the fuel injection amount based on the difference between the fuel injection amount and the flow rate.
