Title
(EN) A FUEL FEED SYSTEM FOR AN INTERNAL COMBUSTION ENGINE
(FR) SYSTEME D'ALIMENTATION EN CARBURANT D'UN MOTEUR A COMBUSTION INTERNE
Abstract
(EN)
A fuel feed system for an internal combustion engine (17) which has unit injectors (18) supplied by a fuel rail (20). The fuel system comprises a fuel tank (11) and a motor driven feed pump (14) situated in an auxiliary reservoir (13). A return pipe (19) delivers fuel back to the auxiliary tank (13) through a venturi type top-up pump (21) which draws fuel from a main reservoir (12) through a non-return valve (27). A venturi type recirculation pump (33) causes fuel to be recirculated through a recirculation duct (34), this duct being connected to the return pipe (19). In a modification (figure 2) the recirculation pump is electric motor driven. In a further modification the recirculation pump comprises an additional pumping element on the feed pump.
(FR)
Un système d'alimentation en carburant d'un moteur à combustion interne (17) comprend des injecteurs unitaires (18) alimentés par un conduit d'acheminement de carburant (20). Ce système comprend un réservoir (11) et une pompe d'alimentation entraînée par un moteur (14) et placée dans un réservoir auxiliaire (13). Un tuyau de renvoi (19) renvoie le carburant au réservoir auxiliaire (13) par une pompe d'appoint de type venturi (212) qui aspire le carburant d'un réservoir principal (12) par l'intermédiaire d'un clapet de non-retour (27). Une pompe de recirculation de type venturi (33) fait recirculer le carburant dans un conduit de recirculation (34), ce conduit étant raccordé à un tuyau de renvoi (19). Dans une autre variante (Fig. 2), la pompe de recirculation est entraînée par un moteur électrique. Selon encore une autre variante, le pompe de recirculation comprend un élément de pompage supplémentaire placé sur la pompe d'alimentation.
