Abstract

L'invention concerne un procédé de fonctionnement d'une soupape magnétique (10), en particulier d'une soupape d'injection d'une installation d'injection de carburant. La soupape magnétique (10) comprend un élément de soupape qui inclut une aiguille de soupape (20) et un induit (14) pouvant se déplacer avec un électroaimant (13) et la course d'ouverture de l'induit (14) est limitée par une butée de course (18). Le procédé comprend les étapes suivantes : (a) détermination du début de l'attaque de l'électroaimant (13) ; (b) détermination de la fin de la course (52) (information d'impact) de l'élément de soupape, à la fin de la course d'ouverture ; (c) détermination d'une temporisation de levée (32) en utilisant le début de l'attaque (38) déterminé, la fin de course (52) déterminée et un temps de déplacement (56) de l'élément de soupape, déterminé au préalable.
