Title (EN) COMMON FUEL RAIL FUEL SYSTEM FOR LOCOMOTIVE ENGINE
(FR) SYSTÈME DE CARBURANT À RAMPE COMMUNE DE CARBURANT POUR MOTEUR DE LOCOMOTIVE
Abstract:
(EN) A common rail fuel injection apparatus (1) for a multi-bank, diesel locomotive engine (10). A common rail (20, 22) is disposed proximate each bank (20, 22) of cylinders (12) of the engine to provide high pressure fuel (30) to a fuel flow control apparatus (14) associated with each respective cylinder. A plurality of high-pressure fuel pumps (34) provides high-pressure fuel to at least one of the common rails. A fluid cross connection (38) is provided to convey high pressure fuel between the two common rails, thereby providing for the continued delivery of fuel to all cylinders in the event of a failure of one of the high pressure pumps. The high-pressure pumps are motivated by fuel lobes (64) located on camshaft sections (50a, 50b, 50c) adjoined at a gear driven end 58 of the camshaft (50). Camshaft sections (50d, 50e, 50f) adjoined at an idler end (60) of the camshaft carry lower torque loads than those sections having fuel lobes and may be formed from a lower strength material or may have a smaller shaft diameter.
(FR) La présente invention concerne un appareil d’injection de carburant à rampe commune (1) pour un moteur de locomotive diesel multibloc (10). Une rampe commune (20, 22) est disposée à proximité de chaque bloc (20, 22) de cylindres (12) du moteur afin de fournir un carburant à haute pression (30) vers un appareil de commande d’écoulement de carburant (14) associé à chaque cylindre respectif. Une pluralité de pompes à carburant à haute pression (34) fournit du carburant à haute pression à au moins l’une des rampes communes. Une interconnexion de fluide (38) est prévue pour transporter du carburant à haute pression entre les deux rampes communes, ce qui fournit ainsi l’acheminement continu de carburant vers tous les cylindres dans le cas d’une défaillance de l’une des pompes à haute pression. Les pompes à haute pression sont motivées par des lobes de carburant (64) situés sur des parties d’arbres à came (50a, 50b, 50c) attenantes à une extrémité entraînée par un engrenage (58) de l’arbre à came (50). Les parties d’arbre à came (50d, 50e, 50f) attenantes à une extrémité de roue folle (60) de l’arbre à came portent des charges de couple inférieures à celles des parties ayant des lobes de carburant et peuvent être formées à partir d’un matériau à plus faible résistance ou peuvent avoir un diamètre d’arbre plus petit.
