Abstract

Procédé de controle de l'alimentation en essence á haute pression (HP) d'un ensemble d'injecteurs reliés á une chambre commune á haute pression, appelée « common rail » C dans un circuit d'Injection Directe d'Essence, appelé I.D.E., par une pompe (P) á haute pression, en agissant sur l'alimentation á basse pression (BP) de ladite pompe (P) au moyen d'une électrovanne á tiroir (E), pilotée par le calculateur gérant le fonctionnement du moteur consistant á aménager, á l'intérieur de l'électrovanne (E) une ou plusieurs fuites internes, soit de la haute pression vers la basse pression, soit de la basse pression en amont de l'électrovanne (E) vers la basse pression en aval ce qui permet de régler les problémes particuliers qui se posent pour les trois modes suivant de fonctionnement du moteur : frein moteur, arrét du moteur, ralenti.
