(FR) MOTEUR À COMBUSTION INTERNE À PLUSIEURS CYLINDRES
Abstract
(DE)
Brennkraftmaschine mit mehreren Zylindern, die zu mindestens zwei Zylinderbänken (B1, B2) zusammengefasst sind, wobei Kraftstoff mittels Injektoren (I1-I8) in Brennräume der Zylinder eingespritzt werden kann und wobei die Injektoren (I1-I8) jeweils mit einem von mindestens zwei Hochdruckrails (R1, R2) verbunden sind, wobei die Injektoren (I1-I8) einer Zylinderbank (B1, B2) mit unterschiedlichen Hochdruckrails (R1, R2) verbunden sind.
(EN)
Internal combustion engine having a plurality of cylinders which are combined to form at least two cylinder banks (B1, B2), wherein fuel can be injected by means of injectors (I1-I8) into combustion chambers of the cylinders, and wherein the injectors (I1-I8) are connected in each case to one of at least two high-pressure rails (R1, R2), wherein the injectors (I1-I8) of one cylinder bank (B1, B2) are connected to different high-pressure rails (R1, R2).
(FR)
Moteur à combustion interne à plusieurs cylindres, qui sont rassemblés en au moins deux bancs de cylindres (B1, B2). Du carburant peut être injecté au moyen d'injecteurs (I1-I8) dans des chambres de combustion des cylindres et les injecteurs (I1-I8) sont chaque fois raccordés à l'une d'au moins deux rampes à haute pression (R1, R2), les injecteurs (I1-I8) d'un banc de cylindres (B1, B2) étant raccordés à des rampes à haute pression différentes (R1, R2).
