Abstract
Description
Die Erfindung betrifft eine Kraftstoffeinspritzvorrichtung für eine Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a fuel injection device for an internal combustion engine according to the preamble of claim 1.
Es
ist eine Hochdruck-Kraftstoffeinspritzvorrichtung bekannt,
In
der
Es ist Aufgabe der Erfindung eine Kraftstoffeinspritzvorrichtung mit einer sicheren Halterung der Einspritzventile zwischen einem Zylinderkopf und einer Kraftstoffverteilerleitung zu schaffen, die die auftretenden Toleranzen gezielt ausgleicht.It Object of the invention with a fuel injection device a secure mounting of the injectors between a cylinder head and a fuel rail to provide the occurring Balances tolerances.
Dies wird nach der Erfindung mit den Merkmalen des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.This is according to the invention with the features of claim 1 solved. Further, the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass die Einspritzventile lagesicher zwischen der Kraftstoffverteilerleitung und dem Zylinderkopf festgelegt sind, dergestalt, dass die auftretenden hohen Einspritz- und Verbrennungsdrücke funktionsgerecht aufgenommen werden. Dabei werden die in Längsrichtung der Kraftstoffverteilerleitung sich ergebenden Fertigungs- und Temperaturtoleranzen durch Längenausgleichselemente der Kraftstoffverteilerleitung mit vertretbarem Aufwand wirkungsvoll ausgeglichen. Dies wird auch noch durch die Dichtvorrichtungen, die zwischen der Rohrleitung und den Schiebehülsen bzw. den äußeren Steckhülsen und den inneren Steckhülsen vorgesehen sind, unterstützt. Dass die Dichtvorrichtung mehrere Dichtringe aufweist, trägt zur guten Funktion der Dichtvorrichtung bei. Die Rohrleitung, die Schiebehülsen und die Steckhülsen sind leicht gestaltbare Bauteile, die auf einfache Weise herstellbar sind. Schließlich ist das Zusammenwirken der Rohrstücke mit den Bohrungsstutzen und die Befestigung der besagten Rohrstücke an den Bohrungsstutzen aufwandsarm realisierbar.The with the invention mainly The advantages achieved are the fact that the injectors are secure in position set between the fuel rail and the cylinder head are such that the high injection and combustion pressures occurring are functional be recorded. In this case, the longitudinal direction of the fuel rail resulting manufacturing and temperature tolerances by length compensation elements the fuel rail with reasonable effort effectively balanced. This is also due to the sealing devices, between the pipe and the sliding sleeves and the outer receptacles and the inner sockets are supported. The fact that the sealing device has a plurality of sealing rings contributes to the good Function of the sealing device at. The pipeline, the sliding sleeves and the receptacles are easily customizable components that can be produced in a simple manner are. After all is the interaction of the pipe sections with the Bohrungsstutzen and the attachment of said pipe pieces to the bore neck Effortless realizable.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher beschrieben wird. In The drawing is an embodiment of the invention, which will be described in more detail below.
