Title (EN) ENGINE HAVING COMMON RAIL INTENSIFIER AND METHOD
(FR) MOTEUR AYANT UN MULTIPLICATEUR DE PRESSION PLACÉ EN AMONT DE LA RAMPE COMMUNE ET PROCÉDÉ CORRESPONDANT
Abstract: front page image
(EN)An internal combustion engine (12) includes an engine housing (16), a common rail (14), and a pressurization device (40) for the common rail fuel system (14) which includes a plurality of intensifier pistons (51, 53), and an hydraulically actuated control valve (60) movable between a first position at which it fluidly connects a source of pressurized actuation fluid (32) with one of said intensifier pistons (51) but not a second one of the intensifier pistons (53), and a second position at which it fluidly connects the at least one fluid inlet with the second one of the intensifier pistons (53) but not the first one (51) of the intensifier pistons (51).
(FR)L'invention concerne un moteur à combustion interne (12) comprenant un carter (16), une rampe commune (14) et un dispositif de pressurisation (40) pour la rampe commune (14) qui comprend une pluralité de pistons multiplicateurs (51, 53) et une soupape de commande hydraulique (60) pouvant se déplacer entre une première position où elle raccorde de manière fluidique une source de fluide d'actionnement pressurisé (32) à l'un des pistons multiplicateurs (51), et une seconde position où elle raccorde de manière fluidique au moins un orifice d'admission du fluide à l'autre piston multiplicateur (53).
