の電子制御燃料噴射装置。 The engine intake system is equipped with a fuel injection valve, and in addition to the regular injection of fuel in an amount according to the engine operating status at a predetermined timing synchronized with the engine rotation, it is also injected at predetermined intervals based on the amount of change in the throttle valve opening. In an electronically controlled fuel injection device for an internal combustion engine that injects fuel in an interruptive manner based on a signal from an acceleration determining means that determines acceleration or non-acceleration of the engine, the acceleration determining means counts the number of consecutive acceleration determinations made by the acceleration determining means. a first interrupt injection means for injecting fuel interruptively when the number of acceleration determinations by the acceleration determination number counting means reaches a predetermined value; and a comparison value for the number of acceleration determinations is variable in accordance with the engine rotational speed. and a comparison value variable means for determining the number of times of acceleration determination by the acceleration determination number counting means during the acceleration determination after the interrupt injection by the first interrupt injection means is a comparison value according to the engine rotation speed determined by the comparison value variable means. 1. An electronically controlled fuel injection device for an internal combustion engine, characterized in that the electronically controlled fuel injection device for an internal combustion engine has a second interrupt injection means for injecting fuel every time the fuel is injected.
