Abstract
Description
Die Erfindung geht aus von einer Brennstoffeinspritzvorrichtung nach der Gattung des Anspruchs 1.The The invention is based on a fuel injection device the genus of claim 1.
Bekannt
ist bereits aus der
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Brennstoffeinspritzvorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, dass die Körperschallübertragung vom Brennstoffeinspritzventil in den Zylinderkopf deutlich reduziert ist. Dies wird erfindungsgemäß dadurch erreicht, dass das Brennstoffeinspritzventil direkt an die Brennstoffverteilerleitung über einen Verbindungskörper angebunden ist, aber weitgehend von der Aufnahmebohrung des Zylinderkopfes abgekoppelt ist. Das Brennstoffeinspritzventil ist in der Aufnahmebohrung des Zylinderkopfes derart angeordnet, dass es anlagefrei zu allen nicht achsparallel zum Brennstoffeinspritzventil verlaufenden Flächen bzw. Wandungen der Aufnahmebohrung eingebracht ist.The Fuel injection device according to the invention with the characterizing features of claim 1 has the advantage that the structure-borne sound transmission significantly reduced from the fuel injector into the cylinder head is. This is inventively characterized achieved that the fuel injection valve directly to the fuel rail via a connecting body Tailored, but largely from the receiving bore of the cylinder head disconnected. The fuel injection valve is in the receiving bore of the cylinder head arranged such that it is not aplict free to all axially parallel to the fuel injection valve extending surfaces or Walls of the receiving bore is introduced.
Der erfindungsgemäße Verbindungskörper ermöglicht in vorteilhafter Weise eine Kippbewegung des Brennstoffeinspritzventils zum radialen Toleranzausgleich zwischen Zylinderkopf und Brennstoffverteilerleitung.Of the inventive connection body allows in Advantageously, a tilting movement of the fuel injection valve for radial tolerance compensation between cylinder head and fuel distributor line.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Brennstoffeinspritzvorrichtung möglich.By in the subclaims listed activities are advantageous developments and improvements in the claim 1 specified fuel injection possible.
Besonders vorteilhaft ist es, zusätzlich zur Entkopplung des Brennstoffeinspritzventils vom Zylinderkopf Dämpfungsscheiben im Verbindungsbereich von Brennstoffverteilerleitung und Zylinderkopf vorzusehen. Diese Dämpfungsscheiben können einfach oder doppelt im Bereich jeder Verschraubung der Brennstoffverteilerleitung am Zylinderkopf eingesetzt werden, so dass das Hochdruckeinspritzsystem zum Zylinderkopf hin noch wirksamer entkoppelt und schallisolierter ist.Especially It is advantageous in addition for decoupling the fuel injection valve from the cylinder head damping discs provide in the connection area of the fuel rail and cylinder head. These damper discs can single or double in the area of each screw connection of the fuel distributor line be used on the cylinder head, so that the high-pressure injection system for Cylinder head even more effective decoupled and soundproofed is.
Von Vorteil ist es, den Niederhalter als Stanz-Biege-Teil auszuführen und derart zu formen und in der Brennstoffeinspritzvorrichtung zu verbauen, dass die durch Biegespannung beanspruchten Flächen der Schrägabschnitte und Anlageabschnitte des Niederhalters senkrecht zu den Schnittkanten verlaufen, die beim Herauslösen des Rohlings für den Niederhalter aus dem entsprechenden Blech entstehen. Auf diese Weise lässt sich die dauerhafte Belastbarkeit der auf Biegung beanspruchten Abschnitte des Niederhaltebügels des Niederhalters erhöhen und eine optimale Niederhaltekraft auf das Brennstoffeinspritzventil zur sicheren Fixierung in der Aufnahmebohrung erzielen.From The advantage is to run the hold-down as punching-bending part and so mold and build in the fuel injector, that claimed by bending stress surfaces of the inclined sections and abutment sections of the hold-down run perpendicular to the cut edges, the leaching out of the blank for the Hold-downs from the corresponding sheet arise. In this way let yourself the permanent load capacity of the sections subjected to bending of the hold-down bar of the hold-down and an optimal hold-down force on the fuel injection valve for secure fixation in the receiving bore.

Niederhalter
Bei bekannten Brennstoffeinspritzvorrichtungen sind Brennstoffeinspritzventile derart in Aufnahmebohrungen eines Zylinderkopfes eingebaut, dass diese unmittelbar oder indirekt über Stützringe an radial verlaufenden Schultern der Aufnahmebohrungen anliegen. Ein solcher Aufbau hat zur Folge, dass sowohl durch die Niederhaltekraft von federnden Niederhaltern und Verschraubungen oder Verspannungen der Brennstoffverteilerleitung am Zylinderkopf als auch durch den in der Brennstoffverteilerleitung innen anliegenden Hochdruck des Brennstoffs das Brennstoffeinspritzventil derart in den Zylinderkopf gedrückt wird, dass eine unerwünscht hohe Körperschallübertragung vom Brennstofeinspritzventil in den Zylinderkopf erfolgt, die in negativer Weise deutlich hörbar sein kann.at known fuel injectors are fuel injectors installed in such receiving bores in a cylinder head that this directly or indirectly via supporting rings abut on radially extending shoulders of the mounting holes. Such a structure has the consequence that both by the hold-down force of resilient hold-downs and fittings or tension the fuel rail on the cylinder head and through the in the fuel distributor line inside high pressure of the Fuel is pressed, the fuel injection valve in the cylinder head, that one undesirable high structure-borne sound transmission from the fuel injection valve into the cylinder head takes place in negative way clearly audible can be.
