Abstract

Die Erfindung bezieht sich auf ein Common Rail Einspritzsystem. Ein Common Rail Einspritzsystem besteht im wesentlichen aus einer Hochdruckpumpe, den Einspritzleitungen und den Injektoren. Um das Common Rail Einspritzsystem möglichst montagefreundlich zu gestalten wird erfindungsgemäß vorgeschlagen, die Einspritzleitungen durch ein einziges Rail 2 zu ersetzen und dieses Rail mittels Schrauben 3 und Pratzen 4 direkt am Zylinderkopf 1 zu befestigen. Die Pratzen 4 bilden mit dem Rail 2 eine bauliche Einheit. Diese Einheit kann mittels der Schrauben 3 zur Abdichtung gegen ein Druckrohr 6 gepreßt werden. Zwischen Rail 2 und Druckrohr 6 kann noch ein Durchflußbegrenzer 7 vorgesehen sein. Durch die bauliche Einheit von Rail 2 und den Pratzen 4 ergibt sich eine äußerst günstige Montagemöglichkeit ( Fig. 2 ) .
