Abstract

L'invention concerne un procédé de fonctionnement d'une pompe haute pression (100) pour la production de haute pression dans un système de rampe commune d'un moteur à combustion interne, doté d'un dispositif de commande (9) électronique, qui effectue un contrôle quantitatif par l'intermédiaire d'au moins deux soupapes d'aspiration (1; 1') électriques; pour identifier la position de montage de la pompe haute pression (100) et l'affectation de la soupape d'aspiration électrique (1; 1') pendant le démarrage du moteur, l'une des soupapes d'aspiration électriques (1; 1') et la modification de la courbe de pression de rail qui en résulte, est détectée par un système de capteurs et attribuée à la soupape d'aspiration électrique (1; 1') concernée, et en raison de l'association unique d'une des soupapes d'aspiration électriques (1; 1'), celles-ci sont ensuite commandés dans la position angulaire correcte.
