Abstract
Description
Die Erfindung bezieht sich auf ein Einspritzventil für eine Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an injection valve for an internal combustion engine the preamble of claim 1.
Es
ist ein Brennstoffeinspritzventil für eine Brennkraftmaschine bekannt,
Aus
der
Aufgabe der Erfindung ist es, eine sichere Lagerung für ein Einspritzventil einer Brennkraftmaschine mit vertretbaren Mitteln zu schaffen, mit dem Kraftstoff unter hohem Druck bspw. direkt in einen Brennraum einspritzbar ist. Dabei sollte aber auch den auftretenden Bauteil- und Wärmedehnungstoleranzen Rechnung getragen werden.task The invention is to provide a secure storage for an injection valve Internal combustion engine with reasonable means to create, with the fuel For example, it can be injected directly into a combustion chamber under high pressure. But also the occurring component and thermal expansion tolerances should Be taken into account.
Nach der Erfindung wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.To The invention achieves this object by the features of the patent 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 das Einspritzventil in der ersten Ventilbohrung des Zylinderkopfs und der zweiten Ventilbohrung einer sich in Längsrichtung des Zylinderkopfs erstreckenden Kraftstoffverteilerleitung funktionsgerecht gehalten wird. Dies wird noch dadurch unterstützt, dass das Befestigungsauge für die Befestigungsschraube mit der Kraftstoffverteilerleitung eine aus einem Stück hergestellte Baueinheit bildet. Der Pressring trägt dazu bei, dass hohe Kraftstoffdrücke –160 bar – realisierbar sind und Toleranzen – Fertigung und Temperatur – in Längsrichtung der Kraftstoffverteilungsleitung und in axialer Richtung des Einspritzventils gezielt ausgeglichen werden. Toleranzgünstig wirkt sich darüber hinaus aus, dass die Werkstoffe der Kraftstoffverteilungsleitung und des Zylinderkopfs in etwa gleiche Ausdehnungskoeffizienten aufweisen. Die Anordnung der rohrförmigen Kraftstoffleitungen in der Kraftstoffverteilerleitung ermöglicht es, letztere bezüglich ihres Widerstandsmoments vorteilhaft auszulegen. Schließlich lässt sich der Pressring mit gängigen Mitteln verwirklichen, und er zeichnet sich durch eine gute Funktion aus.The with the invention mainly achieved advantages are the fact that the injection valve in the first valve bore of the cylinder head and the second valve bore one in the longitudinal direction of Cylinder head extending fuel rail work properly is held. This is further supported by the fact that the fastening eye for the Fixing screw with the fuel rail one off one piece made constructional unit. The press ring helps to achieve high fuel pressures of -160 bar are and tolerances - manufacturing and temperature - in longitudinal direction the fuel distribution line and in the axial direction of the injection valve be specifically compensated. Tolerance also has an effect, that the materials of the fuel distribution line and the cylinder head have approximately the same coefficients of expansion. The order the tubular Fuel lines in the fuel rail make it possible the latter with respect their drag torque advantageous interpreted. Finally, you can the press ring with common Realize means, and it is characterized by a good function out.
