する内燃機関の電子制御燃料噴射装置。 Acceleration detection is equipped with a fuel injection valve in the engine intake system and detects the acceleration state of the engine at predetermined time intervals, in addition to the regular injection of fuel in an amount according to the engine operating state at a predetermined timing synchronized with the engine rotation. An electronically controlled fuel injection device for an internal combustion engine that injects fuel in an interrupt manner based on a signal from the means, comprising: a first interrupt injection means that injects fuel in an interrupt manner when the acceleration detection means detects the start of acceleration; a rotation measuring means for measuring the engine rotation after the interruption injection by the injection means; and a second rotation measuring means for injecting the fuel every two revolutions of the engine measured by the rotation measuring means while the acceleration detection means is detecting the acceleration continuation. An electronically controlled fuel injection device for an internal combustion engine, characterized in that it has an interrupt injection means.
