Abstract
(DE)
Eine Komponente (3), die als Brennstoffleitung (5) oder Brennstoffverteiler (2) ausgebildet sein kann, dient für eine Brennstoffeinspritzanlage (1), welche zum Einspritzen von Brennstoff oder eines Gemisches aus Brennstoff und Wasser mit einem veränderbaren Wasseranteil dient. Die Komponente (3) weist einen Grundkörper (14; 60) auf, an dem ein Hochdruckeingang (15; 63) und zumindest ein Hochdruckausgang (16 - 19; 64) vorgesehen sind, wobei der Brennstoff beziehungsweise das Gemisch von dem Hochdruckeingang (15; 63) durch einen Innenraum (24; 65) des Grundkörpers (14; 60) zu dem zumindest einen Hochdruckausgang (16 - 19; 64) führbar ist und wobei in dem Innenraum (24; 65) ein Einlegekörper (25) angeordnet ist. Der Einlegekörper (25) ist zumindest teilweise aus zumindest einem Werkstoff gebildet ist, der einen Kompressionsmodul (K) aufweist, der zumindest im Wesentlichen entsprechend oder kleiner als ein Kompressionsmodul des Brennstoffs beziehungsweise des Gemisches und/oder kleiner als 30 GPa vorgegeben ist.
(EN)
A component (3) which can be designed as a fuel line (5) or fuel distributor (2) serves for a fuel injection system (1) which serves for injecting fuel or a mixture of fuel and water with a changeable portion of water. The component (3) has a main body (14; 60) on which a high-pressure input (15; 63) and at least one high-pressure output (16 - 19; 64) are provided, wherein the fuel or the mixture can be conducted from the high-pressure input (15; 63) through an interior (24; 65) of the main body (14; 60) to the at least one high-pressure output (16 - 19; 64), and wherein an insert (25) is arranged in the interior (24; 65). The insert (25) is at least partially formed from at least one material which has a bulk modulus (K) which is predefined so as to at least substantially correspond to or to be lower than a bulk modulus of the fuel or of the mixture and/or to be smaller than 30 GPa.
(FR)
Composant (3), réalisée sous la forme d’un conduit de carburant (5) ou d’un distributeur de carburant (2), étant destiné pour une installation d’injection de carburant (1), laquelle est destinée à l’injection de carburant ou d’un mélange de carburant et d’eau comprenant un taux d’eau variable. Le composant (3) comprend un corps de base (14, 60), sur lequel une entrée haute pression (15, 63) et au moins une sortie haut pression (16 - 19, 64), le carburant ou le mélange pouvant être guidé de l'entrée haute pression (15, 63) à travers un espace intérieur (24, 65) du corps de base (14, 60) vers l’au moins une sortie haute pression (16 - 19, 64) et un corps d‘insertion (25) étant disposé dans l’espace intérieur (24, 65). Le corps d’insertion (25) est au moins partiellement formé à partir d’un matériau, lequel présente un module de compression (K) qui est défini comme au moins essentiellement égal ou inférieur au module de compression du carburant ou du mélange et/ou inférieur à 30 GPa.
