Abstract

Kraftstoffeinspritzsystem mit einer Kraftstoffhochdruckquelle (5) und wenigstens einem Injektor (12), der wenigstens eine Einspritzöffnung (15) aufweist, durch die Kraftstoff in einen Brennraum einer Brennkraftmaschine einspritzbar ist. Hierbei ist die Kraftstoffhochdruckquelle (5) und die wenigstens eine Einspritzöffnung (15) über einen kraftstoffführenden Hochdruckkanal (9) miteinander verbindbar. An einem Körper (10; 12), in dem der Hochdruckkanal (9) ausgebildet ist, ist ein Dehnungssensor (20; 20'; 20'') angeordnet, mit dem sich die durch den Druck im Hochdruckkanal (9) bewirkte elastische Formänderung des Körpers (10; 12) bestimmen lässt.
