Title (EN) CONTROL DEVICE AND CONTROL METHOD FOR FUEL INJECTION VALVE
(FR) DISPOSITIF DE COMMANDE ET PROCÉDÉ DE COMMANDE POUR SOUPAPE D'INJECTION DE CARBURANT
Abstract: front page image
(EN) A control device for a fuel injection valve includes a drive circuit that controls open/close operation of the fuel injection valve by passing an exciting current through a solenoid of the fuel injection valve and an ECU that reduces a peak current value as a fuel pressure in a delivery pipe at timing of a start of energization of the fuel injection valve decreases. The ECU reduces the peak current value as an amount of fuel discharged from a high-pressure fuel pump to the delivery pipe reduces.
(FR) L'invention concerne un dispositif de commande pour une soupape d'injection de carburant comprenant un circuit d'attaque qui commande l'opération d'ouverture/de fermeture de la soupape d'injection de carburant en faisant passer un courant d'excitation à travers un solénoïde de la soupape d'injection de carburant et un ECU qui réduit une valeur de courant de crête lorsqu'une pression de carburant dans une conduite de distribution au moment d'un début d'alimentation en courant de la soupape d'injection de carburant diminue. L'ECU réduit la valeur de courant de crête lorsqu'une quantité de carburant évacuée d'une pompe de carburant à haute pression vers la conduite de distribution diminue.
