Title (EN) ELECTRONIC CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE ÉLECTRONIQUE
(JA) 電子制御装置
Abstract:
(EN) Provided is an electronic control device with which it is possible to achieve a desired injection amount of an injector at all times by limiting a change in the valve opening time of the injector, regardless of a change (decrease) in a power supply voltage for opening a valve of the injector. A pre-charge current amount during pre-charge control is varied in steps on the basis of a voltage of an injector valve-opening power supply device 10 during pre-charge control.
(FR) L'invention a trait à un dispositif de commande électronique avec lequel il est possible d'obtenir une quantité d'injection souhaitée d'un injecteur à tout moment en limitant un changement dans le temps d'ouverture de soupape de l'injecteur, indépendamment d'un changement (diminution) d'une tension d'alimentation électrique pour ouvrir une soupape de l'injecteur. Une quantité de courant de précharge pendant la commande de précharge est modifiée en étapes sur la base d'une tension d'un dispositif d'alimentation électrique d'ouverture de soupape d'injecteur 10 pendant une commande de précharge.
(JA) インジェクタを開弁するための電源電圧の変化(低下)によらず、インジェクタの開弁時間の変化を抑えて、常に所望のインジェクタ噴射量を実現することのできる電子制御装置を提供する。 プリチャージ制御を行う際のインジェクタ開弁用電源装置10の電圧に基づいてプリチャージ制御時のプリチャージ電流量を段階的に変化させる。
