Title (EN) PRESSURIZED FUEL SYSTEM FOR AN ENGINE, AND METHOD FOR OPERATING A PRESSURIZED FUEL SYSTEM FOR AN ENGINE
(FR) SYSTÈME DE CARBURANT SOUS PRESSION POUR MOTEUR, ET PROCÉDÉ D'UTILISATION D'UN SYSTÈME DE CARBURANT SOUS PRESSION POUR MOTEUR
Abstract:
(EN) A pressurized fuel injection system for an engine includes a pressure sensor in a low pressure rail, an electronic pressure regulator valve in flow communication with and downstream from the low pressure rail and in flow communication with and upstream from a fuel supply, and a controller configured to receive a pressure signal from the pressure sensor and to control the electronic pressure regulator valve in response to the pressure signal to maintain a target pressure in the low pressure rail.
(FR) L'invention concerne un système d'injection de carburant sous pression destiné à un moteur et comprenant un capteur de pression dans une rampe à basse pression, une soupape de régulation de pression électronique en communication fluidique avec la rampe à basse pression et en aval de celle-ci, et en communication fluidique avec une alimentation en carburant et en amont de celle-ci, et un dispositif de commande conçu pour recevoir un signal de pression provenant du capteur de pression et pour commander la soupape de régulation de pression électronique en réponse au signal de pression pour maintenir une pression cible dans la rampe à basse pression.
