Definitions
- the invention relates to a fuel injection arrangement for the cylinder of an internal combustion engine with one on the cylinder head of the cylinder attached fuel injector.
- a fuel injection arrangement of the type mentioned is known from US 6 009 856.
- the fuel injector is used in this arrangement in a known manner to fuel to inject into the cylinder space of the internal combustion engine.
- strong vibrations occur during operation and noise emissions.
- US 6 009 856 the fuel injector by means of an elastic, noise-damping Embed the mass in a cylindrical sleeve. This sleeve is supported with its lower front end on the cylinder head, while the fuel injector over flanges and in the longitudinal direction of the fuel injector is screwed to the cylinder head.
- the fuel injector can be different pressed deep into the potting compound in the sleeve become.
- the screw connections are in the assembled state of the fuel injector so tight that the associated flanges on the top end of the sleeve seated.
- Such attachment of the fuel injector is very complex since it is completely embedded the fuel injector into an elastic mass and their Enclosure required by a sleeve. A renewal of the Embedding in the event of their damage or aging is included the previously known arrangement practically not possible.
- the fuel injection arrangement accordingly has a fuel injector on which one on the cylinder head of the cylinder Internal combustion engine is attached.
- the arrangement is thereby characterized that between the usually across - but also up to an angle of 45 ° - to the longitudinal axis of the fuel injector extending contact surfaces of Fuel injector on the one hand and cylinder head on the other a damping material is arranged.
- Holding forces is fixed - for example by in Axial screws - they are at right angles contact surfaces extending to the longitudinal axis of the fuel injector on the fuel injector on the one hand and the cylinder head on the other under a substantially perpendicular to the contact areas current load.
- This vertical Force load is from the damping material between the Contact areas added or forwarded, the Damping material advantageously a pure compression is subjected to shear forces.
- the damping material is preferably in the form of a washer formed, wherein the fuel injector is annular surrounds.
- Such an annular formation of the Damping material allows a particularly simple and at the same time secure attachment of the damping material to the fuel injector.
- the damping material from several layers.
- the layers can be different or consist of the same materials.
- By using different layers of damping material can change the thickness of the entire layer as needed can be set. Furthermore, by using different Materials with special properties set a specific desired damping behavior become.
- the layered damping material preferably has one Overall thickness of approx. 2 to 3 mm. With a multi-layer damping material this preferably consists of different ones Layers of the same thickness, for example from five layers with one Thickness of 0.5 mm each.
- the damping material can be metal, rubber and / or a plastic, in particular a tetrafluoroethylene material Act (Teflon®).
- Teflon® tetrafluoroethylene material Act
- the materials used must have the desired damping behavior for vibrations and noises generated in the fuel injector must have, on the other hand, they must be mechanical and be thermally sufficiently stable to withstand the loads to withstand which they during the operation of the fuel injection assembly are exposed. The above materials have been particularly beneficial in this regard proved.
- Figure 1 shows a side view of an internal combustion engine.
- the fuel injectors are from the associated ones Bores in the cylinder head 4 removed, being representative a fuel injector 1 in an exploded view is shown to the type of its attachment in the illustrated holes.
- the fuel injector 1 is an enlarged Side view shown in more detail. It can be seen that the fuel injector 1 is essentially cylindrical is constructed with a longitudinal axis L. Towards this The longitudinal axis L becomes the fuel injector 1 in the bores of the cylinder head 4 used. After striking the broadened trained middle section 6 of the fuel injector 1 on the edge of the hole in the cylinder head this becomes attached to the cylinder head using the stopper 3.
- the Stopper 3 has a central opening and sits with the edges of this opening at the top of the front Fuel injector 1 to this with an axial force (i.e. a force in the direction of the longitudinal axis L, see arrow in Figure 2).
- Figure 3 shows the washer 5 and 5a in cross section. It can be seen that the washer from - in the shown Example five - there are different layers with a single thickness of approx. 0.5 mm, a total thickness of 2.5 mm.
- the individual layers can be the same or also have different thicknesses. Furthermore, they can consist of the same or different materials, whereby the washer 5 is preferably made of metal, rubber and / or a plastic such as Teflon is made.
