Abstract

Un système d'injection de carburant (1) pour moteur alternatif comprend des injecteurs de carburant (2) pour injecter du carburant dans des cylindres du moteur, des pompes d'injection (3) pour acheminer du carburant jusqu'aux injecteurs (2), chaque pompe d'injection comprenant au moins un élément de pompe (5) pour mettre sous pression le carburant à injecter. Chaque injecteur (2) est relié à un élément de pompe séparé (5) par le biais d'une conduite de carburant (4). Une conduite de retour (10) est reliée à la conduite de carburant (4) et est pourvue d'une soupape de commande de pression (12) pour réguler la pression du carburant dans la conduite de carburant (4). Le système d'injection de carburant (1) est pourvu d'une unité de commande (29) conçue pour commander la soupape de commande de pression (12).
