Definitions

  • the fuel pump 12 is controlled by the control unit 24 so that it is switched off when reaching or exceeding an upper pressure threshold p 0 of the fuel pressure in the fuel supply line 13, at which the pressure accumulator 18 has its maximum filling pressure and after the fuel pressure has dropped in the fuel supply line 13 at or below a lower pressure threshold p u for filling or recharging the accumulator 18 is turned on again.
  • an upper pressure threshold p 0 6 bar
  • the lower pressure threshold p u 4 bar.

Abstract

La présente invention concerne un dispositif d’alimentation en carburant pour un moteur à combustion interne (10) dans un véhicule à moteur, le dispositif comportant un réservoir de carburant (11), une pompe à carburant électrique (12) pour le transport du carburant dans une conduite d’amenée du carburant (13), un accumulateur de pression (18) et une unité de commande électronique (24) qui commande la pompe à carburant (12), en fonction de la pression dans la conduite d'amenée du carburant (13), de telle sorte que la pompe soit arrêtée en cas de dépassement d'un seuil de pression supérieur et soit mise en route dans le cas où la pression descendrait en dessous d'un seuil de pression inférieur. Pour réduire la consommation de carburant, l’unité de commande (24) met en route la pompe à carburant (12) même dans le cas où il y a une décélération du moteur à combustion interne (10) et dans le cas où la pression dans la conduite d’amenée du carburant (13) descendrait en dessous du seuil de pression supérieur.
