Definitions
- the invention relates to a decoupling element for a fuel injection device according to the preamble of the main claim.
- FIG 1 an example of a known from the prior art fuel injection device is shown in which a flat intermediate element is provided on a built-in bore in a cylinder head of an internal combustion engine fuel injector.
- such intermediate elements are stored as support elements in the form of a washer on a shoulder of the receiving bore of the cylinder head.
- manufacturing and assembly tolerances are compensated and ensured a lateral force-free storage even with slight misalignment of the fuel injector.
- the fuel injector is particularly suitable for use in fuel injection systems of mixture-compression spark-ignition internal combustion engines.
- the intermediate element is a sub-ring having a circular cross-section which is frusto-conical in a region in which both the fuel injection valve and the wall of the receiving bore in the cylinder head are frustoconical run, arranged and serves as a compensation element for storage and support of the fuel injection valve.
- intermediate elements for fuel injectors u.a. also known from DE 100 27 662 A1, DE 100 38 763 A1 and EP 1 223 337 A1. These intermediate elements are characterized by the fact that they are all constructed in several parts or multi-layered and z.T. Should take over sealing and damping functions.
- the known from DE 100 27 662 Al intermediate element comprises a base and carrier body, in which a sealing means is used, which is penetrated by a nozzle body of the fuel injection valve.
- a multilayer compensating element is known, which is composed of two rigid rings and a sandwiched therebetween elastic intermediate ring. This compensating element allows both a tilting of the fuel injection valve to the axis of the receiving bore over a relatively large angular range as well as a radial displacement of the fuel injection valve from the central axis of the receiving bore.
- a likewise multi-layer intermediate element is also known from EP 1 223 337 A1, wherein this intermediate element is composed of several washers, which consist of a damping material.
- the damping material made of metal, rubber or PTFE is chosen and designed so that a noise attenuation of the vibrations generated by the operation of the fuel injection valve and noise is made possible.
- the intermediate element must, however, include four to six layers to achieve a desired damping effect.
- US 6,009,856 A also proposes to surround the fuel injector with a sleeve and to fill the resulting gap with an elastic, noise-damping mass. This type of noise reduction is very complex, easy to install and expensive.
- the decoupling element according to the invention for a fuel injection device with the characterizing features of claim 1 has the advantage that in a very simple design improved noise reduction is achieved by insulation.
- the decoupling element has a non-linear, progressive spring characteristic, resulting in several positive and advantageous aspects when installing the decoupling element in a fuel injection device with injectors for direct fuel injection.
- the low stiffness of the decoupling element at the idling point allows effective decoupling of the fuel injector from the cylinder head and thereby significantly reduced in noise-critical idling operation introduced into the cylinder head body scarf performance and thus the radiated from the cylinder head noise.
- the high stiffness at nominal system pressure provides low overall fuel injector movement during vehicle operation thereby assuring the durability of the gaskets which serve as a combustion chamber gasket and seal against the fuel rail and a stable spray point of the fuel spray in the combustion chamber. which is crucial for the stability of some firing processes.
- the spring characteristic of the decoupling element according to the invention by adjusting the geometric parameters (rolling radii Ri and R 2 , Aufstands sacrificer in the undeformed state Di and D 2 , component height Hi) can be designed specifically progressive.
- the decoupling element is characterized by a low height, making it similar to a plate spring can be used even in a small space.
- the decoupling element also has a high fatigue strength even at high temperatures. As a rotationally symmetrical component, both the design calculation and the production are easily possible for the decoupling element.
- the same decoupling element can also be installed so that the upper boundary surface of
- Decoupling element in the undeformed state in a large diameter region with a contact diameter Di rests against the valve housing of the fuel injection valve, while the lower boundary surface of the decoupling element contacts the receiving bore in a small diameter region with a contact diameter D 2 .

- the fuel injection valve 1 is part of the fuel injection device.
- the fuel injection valve 1 which is designed in the form of a direct-injection injector for injecting fuel directly into a combustion chamber 25 of the internal combustion engine, is installed in a receiving bore 20 of a cylinder head 9.
- a sealing ring 2, in particular of Teflon®, ensures optimum sealing of the fuel injection valve 1 with respect to the wall of the receiving bore 20 of the cylinder head 9.
- the fuel injection valve 1 has at its upstream end 3 a
- the fuel injection valve 1 is inserted into a receiving opening 12 of the connection piece 6 of the fuel distribution line 4.
- the connecting piece 6 is in this case e.g. in one piece from the actual fuel distributor line 4 and has upstream of the receiving opening 12 a smaller diameter flow opening 15 through which the flow of the fuel injection valve 1 takes place.
- the fuel injection valve 1 has an electrical connection plug 8 for the electrical contacting for actuating the fuel injection valve 1.
- a holding-down device 10 is provided between the fuel injection valve 1 and the connecting piece 6.
- the hold-down 10 is designed as a bow-shaped component, e.g. as a punching and bending part.
- the hold-down device 10 has a part-ring-shaped base element 11, from which a hold-down bar 13 extends, which abuts against a downstream end face 14 of the connecting piece 6 on the fuel distributor line 4 in the installed state.
- the object of the invention is to achieve over the known insectsieri treatmentsen in a simple manner improved noise reduction, especially in noise-critical idling operation, by a targeted interpretation and geometry of the intermediate element 24.
- the authoritative source of noise of the fuel injection valve 1 in the direct high-pressure injection are introduced during the valve operation in the cylinder head 9 forces (structure-borne sound), the lead a structural excitation of the cylinder head 9 and are emitted from this as airborne sound.
- a minimization of the introduced into the cylinder head 9 forces should be sought. In addition to reducing the forces caused by the injection, this can be achieved by influencing the transmission behavior between the fuel injection valve 1 and the cylinder head 9.
- the bearing of the fuel injection valve 1 can be mapped on the passive intermediate member 24 in the receiving bore 20 of the cylinder head 9 as a conventional spring-mass damper system, as shown in Figure 2.
- the mass M of the cylinder head 9 can be assumed to be infinite compared to the mass m of the fuel injection valve 1 in the first approximation.
- the transmission behavior of such a system is characterized by a gain at low frequencies in the range of the resonant frequency f R and an isolation range above the decoupling frequency f E (see FIG. 3).
- Isolation as much of the audible frequency spectrum includes. This can be achieved via a lower rigidity c of the intermediate element 24. 2. Increase the damping properties (e.g., friction) of the intermediate element
- the aim of the invention is the design of an intermediate element 24 under the priority use of the elastic isolation (decoupling) for noise reduction, especially in idling mode of the vehicle.
- the invention encompasses, on the one hand, the definition and design of a suitable spring characteristic taking into account the typical requirements and boundary conditions in direct fuel injection with variable operating pressure and, on the other hand, the design of an intermediate element 24 which is capable of reproducing the characteristic of the spring characteristic defined in this way and of a Choice of simple geometric parameters can be adapted to the specific boundary conditions of the injection system.
- Decoupling element 240 is called, in addition to the small space by a restriction of the permissible maximum movement of the fuel injection valve 1 during engine operation difficult.
- the following quasi-static load conditions typically occur in the vehicle: 1. the static hold-down force F NH applied after assembly by a hold-down device 10,
- the functional requirements for the spring characteristic of the decoupling element 240 are:
- a non-linear spring characteristic with a progressive profile for the decoupling element 240 is proposed according to the invention, as sketched in FIG.
- the characteristic of this spring characteristic allows a noise decoupling with the aid of a low spring stiffness (S NVH ) in idling mode and allows the rapid increase in stiffness compliance with the maximum movement of the fuel injection valve 1 between idle and system pressure.
- the decoupling element 240 is inventively similar to a plate spring formed due to the special geometric Design of their cross-sectional geometry generates a significantly progressive spring characteristic.
- it differs significantly from conventional disc springs, which basically initially have only a linear or degressive characteristic curve.
- a progressive course is achieved only when they are almost completely loaded on "block".
- FIGS. 5 and 6 show two embodiments of decoupling elements 240, which are distinguished by a lenticular cross-sectional geometry and, due to their specific geometry, the desired progressive one Cause spring characteristic.
- the progressivity of the decoupling element 240 can be easily designed by adapting a few geometric parameters, as indicated in FIG. 5.
- the lenticular cross-sectional geometry of the decoupling element 240 is selected such that an upper boundary surface 30 has a convex curvature with a first radius Ri and an opposing lower boundary surface 31 has a convex curvature with a second radius R 2 .
- radially inward and outward decoupling element 240 is limited in each case, for example, by vertical end faces 32, 33, which thus define the inner diameter D 3 and the outer diameter D 4 of the decoupling element 240 in the undeformed state.
- the end faces 32, 33 are not functionally relevant and can therefore also deviate from a vertical course.
- the decoupling element 240 has a component height Hi.

- Di and D 2 are also referred to as Aufstands mismesser in the undeformed state.
- the non-linear, progressive spring characteristic of the decoupling element 240 is realized by a shortening of the lever arm, which is defined by the radial distance of the upper and lower contact point at Di and D 2 , with increasing load of the decoupling element 240.
- a smaller lever arm causes a higher rigidity of the decoupling element 240.
- the Hebelarmverkürzung is achieved by the unrolling of the decoupling element 240 with its two convex boundary surfaces 30, 31 on the respective contact partners, ie cylinder head 9 and valve housing 22.
- progressive spring characteristic can also be adapted very specifically to the respective application by means of more complex rolling geometries by providing different radii on the upper limiting surface 30 and / or on the lower limiting surface 31, so that transitions between different rolling radii are produced.
- a Hebelarmverkürzung by the unwinding of the decoupling element 240 in the loaded state with a comparable noise-reducing effect is also possible if the decoupling element 240 is installed in the reverse position in the fuel injection device.
- the upper boundary surface 30 of the decoupling element 240 with the first radius Ri in the built undeformed state in the fuel injector in a large diameter portion Di on the shoulder 21 of the valve housing 22 of the fuel injection valve 1 while the lower boundary surface 31 of the decoupling element 240 with the second radius R 2 in the installed state, the shoulder 23 of the receiving bore 20 in the cylinder head 9 in a small diameter portion D 2 touches.
- Inner diameter D 3 and the outer Aufstandrete close to the outer diameter D 4 and the inner radial distance between the Aufstandriosen at Di and D 2 (lever arm length) is greater than the respective outer radial distances from the Aufstandsriosen at Di and D 2 to the inner diameter D. 3 or outer diameter D 4 -
- Hebelarmverkürzung can also be realized with non-parallel bearing surfaces (paragraph 21, shoulder 23), if, for example, the fuel injection valve 1 and / or the receiving bore 20 in the cylinder head 9 in the region of the decoupling element 240 to be introduced frusto-conical walls.
- a two-part solution is useful, as shown in FIG.
- a support element 35 may be provided, which towards the decoupling element 240 towards a paragraph 21 'similar to the paragraph 21st of the fuel injection valve 1, while the fuel injector 1 inwardly, the support member 35 has a curved contact surface 36 to which the fuel injection valve 1 can be supported, for example, with a frusto-conical valve housing 22.
- the rigidity of the additional support element 35 must also be taken into account.
