Title (EN) FUEL SYSTEM FOR A COMBUSTION ENGINE, COMBUSTION ENGINE WITH SUCH A FUEL SYSTEM, VEHICLE WITH SUCH A FUEL SYSTEM, AND METHOD FOR DAMPING PRESSURE FLUCTUATIONS IN A FUEL SYSTEM
(FR) SYSTÈME DE CARBURANT POUR MOTEUR À COMBUSTION, MOTEUR À COMBUSTION DOTÉ D'UN TEL SYSTÈME DE CARBURANT, VÉHICULE DOTÉ D'UN TEL SYSTÈME DE CARBURANT ET PROCÉDÉ D'ATTÉNUATION DES FLUCTUATIONS DE PRESSION DANS UN SYSTÈME DE CARBURANT
Abstract:
(EN) The invention relates to a fuel system (4) for a combustion engine (2), which system (4) comprises a fuel filter device (24) situated between a low-pressure pump (22) operated by electric motor and a high-pressure pump (26), which device (24) comprises a filter housing (46) in which a filter element (32) and, integrated therewith, an accumulator (34) for damping pressure fluctuations in the fuel system (4) are situated. The fuel filter device (24) is provided with an electrically operable valve (36) for controlling the accumulator (34). The invention relates also to a combustion engine (2) with such a fuel system (4), a vehicle (1 ) with such a fuel system (4) and a method for damping pressure fluctuations in a fuel system (4).
(FR) L'invention se rapporte à un système de carburant (4) pour un moteur à combustion (2), ledit système (4) comprenant un dispositif filtre à carburant (24) situé entre une pompe basse-pression (22) actionné par un moteur électrique et une pompe haute-pression (26), ledit dispositif (24) comprenant un boîtier (46) de filtre dans lequel se trouvent un élément filtrant (32) et, intégré à celui-ci, un accumulateur (34) pour atténuer les fluctuations de pression dans le système de carburant (4). Le dispositif filtre à carburant (24) est doté d'une soupape électrique (36) destinée à commander l'accumulateur (34). L'invention se rapporte aussi à un moteur à combustion (2) doté d'un système de carburant (4), à un véhicule (1) doté d'un tel système de carburant (4) et à un procédé destiné à atténuer les fluctuations de pression dans un système de carburant (4).
