Abstract

Diese Halterung für eine Einspritzdüse eignet sich insbesondere für Brennkraftmaschinen mit Direkteinspritzung. Die Einspritzdüse (9) weist einen Düsenkörper (11) auf, dessen zylindrische erste und zweiten Endstücke (12,13) mit ersten und zweiten Bohrungen (14,15) von Komponenten der Brennkraftmaschine zusammenwirken. Zur einfachen Montage und systemdichten Festlegung der Einspritzdüse greift am Düsenkörper eine Spanneinrichtung (16) an, die das erste Endstück (12) mit definierter Vorspannung in der ersten Bohrung (14) eines Zylinderkopfs (2) in Lage hält. Dabei arbeitet das zweite Endstück (13) vorzugsweise unter Vermittlung einer Zwischenhülse (17) mit der zweiten Bohrung (15) einer Sauganlage (3) zusammen.This holder for an injection nozzle is particularly suitable for Direct injection internal combustion engines. The injector (9) has a nozzle body (11), the cylindrical first and second End pieces (12, 13) with first and second bores (14, 15) from Components of the internal combustion engine interact. For easy assembly and system-tight definition of the injection nozzle engages the nozzle body a tensioning device (16) with the first end piece (12) defined preload in the first bore (14) of a cylinder head (2) holds in place. The second end piece (13) preferably works by means of an intermediate sleeve (17) with the second bore (15) a suction system (3) together.
