Claims (1)
する内燃機関において、各燃料噴射弁を同一噴射
タイミングで駆動するとともに、各燃料噴射弁の
針弁のリフト量をその気筒の吸気量に応じて設定
することにより、同一噴射時間での燃料噴射量を
気筒ごとに調節して各気筒の空燃比をバランスさ
せるように構成した燃料噴射制御装置。 In an internal combustion engine that has multiple cylinders each with a fuel injection valve, each fuel injection valve is driven at the same injection timing, and the lift amount of the needle valve of each fuel injection valve is adjusted according to the intake air amount of that cylinder. A fuel injection control device configured to adjust the fuel injection amount for the same injection time for each cylinder and balance the air-fuel ratio of each cylinder by setting the fuel injection amount.
