Title (EN) ENGINE CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE MOTEUR
(JA) エンジンの制御装置
Abstract:
(EN) This control device is for an engine 1 provided with an injector 40. The injector 40 has a needle 42 that is displaced between a closed position for blocking flowing of fuel into a sack part 48 and an open position for permitting flowing of the fuel into the sack part 48. The control device has: a fuel injection control unit that controls a fuel injection period; and an injector control unit that controls the motion of the needle 42. The injector control unit executes control for reducing the moving speed of the needle 42 before the needle 42 reaches the closed position when the injection period ends.
(FR) La présente invention concerne un dispositif de commande destiné à un moteur (1) pourvu d'un injecteur (40). L'injecteur (40) comprend une aiguille (42) qui est déplacée entre une position fermée destinée à bloquer l'écoulement du carburant dans une partie sac (48) et une position ouverte destinée à permettre l'écoulement du carburant depuis la partie sac (48). Le dispositif de commande comprend : une unité de commande d'injection de carburant qui commande une période d'injection de carburant ; et une unité de commande d'injecteur qui commande le mouvement de l'aiguille (42). L'unité de commande d'injecteur exécute une commande destinée à réduire la vitesse de déplacement de l'aiguille (42) avant que l'aiguille (42) n'atteigne la position fermée lorsque la période d'injection se termine.
(JA) インジェクタ40を備えたエンジン1の制御装置である。インジェクタ40は、サック部48へ燃料を流入させない閉じ位置と、サック部48へ燃料を流入させる開き位置とに変位するニードル42を有している。制御装置は、燃料の噴射期間を制御する燃料噴射制御部と、ニードル42の動作を制御するインジェクタ制御部とを有している。インジェクタ制御部は、噴射期間終了時に、ニードル42の移動速度を減速させる制御を、ニードル42が閉じ位置に到達する前に実行する。
