Abstract

L'invention concerne un système d'alimentation en carburant (1) d'un moteur à combustion interne, en particulier d'un véhicule à moteur. Le système d'alimentation en carburant (1) comprend une pompe (4, 6) de refoulement du carburant dans un réservoir (2) et de génération d'une pression (préelle) dans le réservoir (2). Un capteur de pression (9) mesure une valeur réelle (Upréelle) de la pression (préelle) dans le réservoir (2) et une soupape de commande de la pression (10) modifie la pression (préelle) dans le réservoir (2). Un appareil de commande (11) comprend des moyens qui permettent de régler la pression dans le réservoir (2) sur une valeur nominale (Upnom). L'appareil de commande (11) comprend en outre des moyens qui permettent de remplacer le réglage de la pression dans le réservoir (2) par une commande.
