Definitions
- the invention relates to a fuel supply device specified in the preamble of claim 1 species and a method for producing such a fuel supply device specified in the preamble of claim 9 Art.
- EP 1 772 60 B1 discloses a generic device for fastening a high-pressure fuel accumulator to a cylinder head with a high-pressure fuel accumulator, which has a main line running along a longitudinal axis. Furthermore, the device comprises a plurality of fluid-tight passages, which are completely formed extending through said high-pressure fuel accumulator and extend substantially perpendicular to the longitudinal axis, and a plurality of screws, which are to be inserted through the respective plurality of fluid-tight passages.
- the fastening elements can be attached to the cylinder head, as a result of which the high-pressure fuel accumulator is fastened to the cylinder head.
- the fluid-tight passages are completely formed by the said main line of the high-pressure fuel accumulator.
- This device has the disadvantage of an increased risk of leaks, allowing fuel to escape from the high pressure fuel reservoir, unless otherwise precautions are taken.
- a fuel supply device for attachment to a cylinder head of an internal combustion engine with at least one fuel distributor element extending along a longitudinal direction and with at least one transverse, in particular perpendicular, to the longitudinal direction connecting element, via which the fuel distribution element is connectable to the cylinder head, characterized by at least one stiffening element which is connected on the one hand with an outer circumferential surface of the fuel distribution element and on the other hand with the connecting element outside, in particular exclusively outside, of the fuel distribution element.
- the stiffening element By the stiffening element, the connection between the fuel distribution element, which is also referred to as a fuel rail, stiffened and the connecting element. It follows that the probability of an occurrence of leaks and thus leakage of fuel received in the fuel distribution element is significantly reduced.
- the stiffening element is connected to an outer circumferential surface of the fuel distribution element, a particularly large connecting surface between the stiffening element and the fuel distribution element is available. This results in lower stresses in this interface with very high pressure fuel in the fuel distribution element. This is advantageous in particular when the stiffening element is materially connected, in particular soldered, to the fuel distribution element and / or to the connecting element. Due to the large available connection surface, the mechanical stress is low, for example in the soldering seam. Even with a very high internal pressure of the fuel distribution element and in the presence of biasing forces of the fuel supply device cooperating injectors, the large connection surface is less heavily loaded, whereby a low probability of failure, for example, the solder seam and thus destruction of the entire fuel supply device is given.
- the advantages outlined here can be achieved without increasing a wall thickness of the fuel distribution element and thus its weight. This keeps the total weight of the fuel supply device in a small frame. Also, the number of attachment points and connecting surfaces between the connecting element and the fuel distribution element can be kept low, which in turn leads to a low weight and low cost of the fuel supply device.
- a connecting surface between the stiffening element and the connecting element is particularly large, with low voltages and due to the large connecting surface even at a high in the fuel distribution element prevailing internal pressure, in the presence of mechanical preload forces by fastened injection valves and connected to the cylinder head fuel supply device low voltages and so that there is a low load in the connection surface. If the stiffening element and the connecting element are soldered to one another, this means a low load on the soldered seam, which has a positive effect on the functional performance of the fuel supply device.
- the stiffening element is formed as a stiffening plate, which advantageously has a corresponding to an outer contour of the fuel distribution member receptacle in which the fuel distribution element is at least partially received, and which extends obliquely, in particular transversely to the longitudinal direction of the fuel distribution element.
- the stiffening element thus has a collar shape, through which the fuel supply device is stiffened in the connecting region between the fuel distribution element and the connecting element. The functional performance of the fuel supply device is given in a particularly high degree when the connecting element with the fuel distribution element materially connected, in particular soldered, is.
- a particularly strong and rigid connection with a long service life is realized in a particularly preferred embodiment of the invention in which a receiving space is formed between the stiffening element and the connecting element and / or between the stiffening element and the fuel distribution element, in which a connecting means, in particular, a connecting means for integrally joining the stiffening element with the connecting element and / or the stiffening element is received with the fuel distribution element, such as solder, adhesive and / or the like.
- a particularly large area for forming, for example, a soldering seam is available, whereby the stresses in the soldering seam are extremely low.
- the stiffening element has at least one passage opening into the receiving space, through which the connecting means, such as the solder, is introduced.
- the connecting means such as the solder
- the fuel supply device comprises two stiffening elements which are connected on the one hand to the outer lateral surface of the fuel distribution element and on the other hand to the connecting element outside, in particular exclusively outside, of the fuel distribution element.
- the connecting element penetrates the fuel distribution element and projects beyond it in the axial direction of the connecting element on both sides, ie on both an upper and on an underside by a certain distance.
- One of the two connecting elements is now arranged, for example, on the upper side of the fuel distribution element and on the one hand connected to the outer lateral surface thereof and on the other hand to the connecting element.
- the second of the stiffening elements is then arranged on the underside and connected on the one hand to the outer circumferential surface of the fuel distribution element and on the other hand to the connecting element.
- the connection of the connecting element with the fuel distribution element is particularly strong.
- the stresses in respective connecting surfaces between the respective stiffening elements and the connecting element or the fuel distribution element are very low, resulting in a long service life of the fuel supply device.
- the invention also includes a method for producing a fuel supply device for attachment to a cylinder head of an internal combustion engine having at least one fuel distribution element running along a longitudinal direction and having at least one transverse, in particular perpendicular, to the longitudinal direction connecting element via wherein the fuel distribution element is connectable to the cylinder head, wherein in a step of the method, a receiving space between an extension piece and the fuel distribution element and / or the connecting element for a connecting means for connecting the extension piece with the fuel distribution element and / or the connecting element is formed.
- the connecting means can be arranged or introduced, whereby a particularly large connecting surface between the extension piece and the fuel distribution element and / or the connecting element is given. This, too, keeps the load on the connection surface, in particular stresses in it, low, as a result of which a fuel supply device is created which has a high functional performance safety and thus a long service life.

- FIG. 1 shows a high-pressure fuel accumulator 10 with a fuel distribution pipe 12 for a direct-injection gasoline or diesel engine.
- fuel is pressurized by a high-pressure pump and fed into the fuel distribution pipe 12, which distributes it to injectors.
- the injectors inject the fuel into respective cylinders.
- receptacles 14, 16, 18 and 20 of the high-pressure fuel accumulator 10 are provided, in each of which an injector is inserted and thus can be supplied with fuel from the fuel distribution pipe 12.
- the high-pressure fuel accumulator 10 comprises sleeves 22 and 24 for connecting the high-pressure fuel accumulator 10 to a cylinder head of the Otto or Diesel engine.
- the sleeve 22 penetrates the fuel distribution pipe 12 completely, is thus passed through corresponding passage openings in an outer circumferential surface 26 of the fuel distribution pipe 12 and penetrates these through holes.
- the sleeve 22 is inserted into a corresponding receptacle of the sleeve 24. So that no fuel can escape between the sleeves 22 and 24, a sealing element 28 is provided in the axial direction of the sleeves 22 and 24 according to a directional arrow 27 between them.
- the high-pressure fuel accumulator 10 includes stiffening plates 30, wherein the respective stiffening plate 30 is soldered on the one hand to the outer circumferential surface 26 and on the other hand exclusively outside of the fuel distribution tube 12 with the sleeve 24.
