算出し、これに相応する噴射パルスによりスロツ
トル弁上流に設けた燃料噴射弁を駆動して燃料を
噴射する一方、減速時には燃料噴射を停止し、該
停止中に設定回転数以下となつた時に燃料噴射を
再開するようにした内燃機関の電子制御燃料噴射
装置において、燃料噴射の再開時には噴射パルス
を増大補正して出力する手段と、燃料噴射再開後
に機関回転数が所定回転数以下になつた時に噴射
パルスの増大補正を解除する手段とを設けたこと
を特徴とする内燃機関の電子制御燃料噴射装置。 The fuel injection amount is calculated based on the intake air amount and the engine rotational speed, and a corresponding injection pulse is used to drive a fuel injection valve installed upstream of the throttle valve to inject fuel, while stopping fuel injection during deceleration. In an electronically controlled fuel injection device for an internal combustion engine, which restarts fuel injection when the rotation speed becomes lower than a set rotation speed during the stop, there is provided a means for increasing and outputting an injection pulse when restarting fuel injection, and restarting fuel injection. 1. An electronically controlled fuel injection device for an internal combustion engine, comprising means for canceling the injection pulse increase correction when the engine speed later becomes less than a predetermined speed.
