Title
(DE) Komponente, insbesondere Brennstoffleitung oder Brennstoffverteiler, und Brennstoffeinspritzanlage
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. embedded image
