Definitions
- the invention relates to a suspension for fuel injection systems for connecting a fuel injection valve with a fuel-carrying component and a fuel injection system with such a suspension.
- the invention relates to the field of fuel injection systems for mixture-compressing, spark-ignited internal combustion engines.
- a fuel injection device with a sound-decoupling construction comprises a fuel injection valve, a receiving bore for the fuel injection valve in a cylinder head and a fuel distribution line with a connection piece.
- the fuel injector is partially inserted into the connecting piece.
- the fuel injector has a wire ring inserted in a groove in the area of its inlet connection.
- a connection body in the form of a locking nut is provided, which is screwed onto an external thread on the circumference of the connecting piece.
- the connecting body has a section containing an internal thread, to which an annular collar adjoins, which has a curved support surface in the form of a ball socket. With this support surface, the annular collar of the connecting body is supported on the wire ring, which is received with its curvature in the annular collar.
- the ones from the DE 10 2005 020 380 A1 The known embodiment of the fuel injection device has the disadvantage that vibrations can be transmitted between the connecting piece and the inlet connecting piece of the fuel injection valve via the wire ring. In particular, vibrations can be transmitted from the fuel injector to the connecting piece.
- valve tickers Especially with electromagnetic high-pressure injection valves, which are used in Otto engines with direct injection, a noticeable and annoying contribution to the overall noise of the engine can be made, which can be described as valve tickers.
- Such a valve ticking occurs due to the rapid opening and closing of the fuel injector, in which the valve needle is moved into the respective end stops with high dynamics.
- the impact of the valve needle in the end stops leads to short-term but very high contact forces which are transmitted via a housing of the fuel injector to the cylinder head and a fuel rail in the form of structure-borne noise and vibrations. This leads to a high level of noise on the cylinder head and on the fuel rail.
- the suspension according to the invention with the features of claim 1 and the fuel injection system according to the invention with the features of claim 8 have the advantage that an improved suspension of the fuel injector on the fuel-carrying component is made possible.
- noise can be reduced through targeted decoupling.
- a soft connection of the fuel injection valve to the fuel-carrying component can be achieved, which enables a noise reduction in the overall system with the fuel injection system.
- the suspension and fuel injection system are particularly suitable for gasoline direct injection applications.
- the fuel-carrying component is preferably designed as a fuel distributor, in particular as a fuel distributor strip.
- a fuel distributor can, on the one hand, serve to distribute the fuel to a plurality of fuel injection valves, in particular high-pressure injection valves.
- the fuel distributor can serve as a common fuel reservoir for the fuel injection valves.
- the fuel injection valves are then preferably connected to the fuel distributor via corresponding suspensions. During operation, the fuel injection valves then inject the fuel required for the combustion process under high pressure into the respective combustion chamber.
- the fuel is compressed by a high pressure pump and pumped into the fuel distributor in a quantity controlled manner via a high pressure line.
- the fuel injector in particular the fuel connector, is not part of the suspension according to the invention.
- the suspension according to the invention can also be manufactured and sold separately from the fuel injector.
- the connection body can be part of a fuel-carrying component.
- the connection body can be designed as part of a cup of a fuel distribution rail. In this case, however, the connection body can also be connected at a later point in time to a tubular base body or the like of the fuel distribution rail, for example by welding.
- the suspension according to the invention is not necessarily part of the entire fuel-carrying component and can also be manufactured and sold independently of such other components of a fuel-carrying component.
- a soft connection of the fuel injection valve to the fuel-carrying component in particular a fuel distributor, can be achieved.
- a significant noise reduction in the overall system with the fuel injection system is possible through a soft design of this interface.
- the soft connection of the fuel injector to the fuel-carrying component can take place with a target stiffness of not more than 50 kN / mm, whereby the strength requirements can be met over the lifetime.
- the advantage of the soft suspension is a significant reduction in the structure-borne noise transmitted from the fuel injector to the fuel-carrying component and, associated therewith, a reduction in the noise of the injection system.
- this noise-reducing measure can be used in addition to other noise-reducing measures, such as a hydraulic throttle at the valve inlet and a soft rail screw connection.
- the suspension can be used in an advantageous manner with no or only minor structural changes in existing structures. This results in a wide range of applications.
- a contact surface is configured on the inner collar of the connection piece, which is configured conically with respect to a longitudinal axis of the receiving space and faces the receiving space.
- Advantageous centering is ensured by the conical contact surface, which can have an opening angle from a range of approximately 10 ° to approximately 80 °, in particular of at least approximately 45 °, particularly with respect to the longitudinal axis.
- an angle tolerance compensation for the fuel injector with respect to the longitudinal axis of the receiving space can be ensured.
- the angle tolerance compensation can also be used here can be realized by elastic deformation of the elastically deformable element. An alignment of the elastically deformable element with respect to the longitudinal axis of the receiving space and thus the alignment of the fuel connector of the fuel injector takes place at least indirectly via the conical contact surface.
- annular support element is provided and that the elastically deformable element is supported by means of the annular support element on the inner collar of the connection piece.
- the conical contact surface is also provided on the inner collar of the connection piece.
- An alignment of the annular support element with respect to the longitudinal axis of the receiving space is thereby achieved.
- the annular support element preferably has a rounded outer contour in relation to the contact surface of the inner collar. This ensures tolerance compensation at the interface between the annular support element and the inner collar, with self-centering occurring during operation.
- the annular support element has an annular recess into which the elastically deformable element is at least partially inserted.
- the annular recess of the annular support element is designed to be open inward.
- elastic deformability of the elastically deformable element is also made possible in the radial direction, since radial support on the annular support element is ensured.
- direct contact between the annular support element and an outside of the fuel connector can be avoided as a result.
- deformation of the elastically deformable element can still be limited.
- the ring-shaped angle element rests on an outside of the fuel connector. This enables the annular angular element to be reliably fixed on the fuel connector, so that vibrations are transmitted directly to the elastically deformable element. Contact noises between the annular angle element and the fuel connector are thus prevented from the outset.
- the element connected to the fuel connector is materially connected to the fuel connector.
- the element connected to the fuel connector can be designed as a disk-shaped element that is welded to the fuel connector.
- a U-shaped connection bracket is provided, that the connection piece is connected to the connection body via the U-shaped connection bracket, that the connection body has at least one recess on its outside, that the connection piece has at least one recess on its inside which is assigned to the recess of the connection body, that the U-shaped connecting bracket engages inside the at least one recess of the connection body and outside the at least one recess of the connector and that the U-shaped connecting bracket is oriented at least approximately perpendicular to a longitudinal axis of the receiving space .
- the connection piece is connected to the connection body via the U-shaped connection bracket, that the connection body has at least one recess on its outside, that the connection piece has at least one recess on its inside which is assigned to the recess of the connection body, that the U-shaped connecting bracket engages inside the at least one recess of the connection body and outside the at least one recess of the connector and that the U-shaped connecting bracket is oriented at least approximately perpendicular to a longitudinal axis of
- the disk-shaped element can be connected to the fuel connector by welding.
- the fuel nozzle can be positioned together with the connector on the fuel-carrying component.

- the fuel injection system 1 can be used in mixture-compressing, externally ignited internal combustion engines.
- the suspension 2 is particularly suitable for such a fuel injection system 1.
- the fuel injection system 1 has a fuel-carrying component 3 which, in this exemplary embodiment, is designed as a fuel rail 3.
- the fuel rail 3 has a tubular base body 4 and a connection body 5.
- An elongated fuel chamber 6 is formed in the tubular base body 4, from which a connecting channel 7, which is guided through the connecting body 5, branches off.
- further connection bodies, which are configured in accordance with the connection body 5, are preferably attached to the tubular base body 4.
- the connection body 5 is part of the suspension 2.
- the connection body 5 can be connected to the tubular base body 4 in a suitable manner.
- the tubular base body 4 is not necessarily a component of the suspension 2, because the suspension 2 with the connection body 5 can also be manufactured and sold independently of the tubular base body 4.
- connection body 5 can then be connected to the tubular base body 4 together with further correspondingly configured connection bodies, which is possible, for example, by welding.
- the connection body 5 has an external thread 8.
- the suspension 2 has a connection piece 9 with an internal thread 10. At least in the area of the internal thread 10, the connection piece 9 is tubular.
- the connection piece 9 has an inner collar 12 on an end face 11.
- the connection piece 9 is screwed with its internal thread 10 onto the external thread 8 of the connection body 5.
- the connection piece 9 is thus designed in the form of a union nut 9.
- the connection body 5 is designed as a rail cup 5 in this exemplary embodiment.
- connection body 5 and the connection piece 9 are thus connected to one another.
- a receiving space 15 is formed inside the connection body 5 and the connection piece 9, in which a fuel connector 16 of a fuel injection valve 17 of the fuel injection system 1 is partially arranged.
- the fuel connector 16 has a collar 18 on which an inlet for the fuel is provided in order to guide the fuel from the connecting channel 7 into a fuel chamber 19 in the interior of the fuel injector 17.
- a sealing ring 20 is provided, which is located between the fuel nozzle 16 and the connection body 5 in order to form a seal.
- the sealing ring 20 is located between the collar 18 and a support ring 21.
- the support ring 21 encloses a tapered section of the fuel nozzle 16.
- a contact surface 22 is configured on the inner collar 12 of the connection piece 9.
- the contact surface 22 here faces the receiving space 15. Furthermore, the contact surface 22 is configured conically with respect to a longitudinal axis 23 of the receiving space 15. An opening angle for the contact surface 22 can be approximately 45 °, for example.
- annular support element 24 is provided on which a rounded edge 25 is configured.
- the annular support element 24 is arranged in the receiving space 15 and encloses the fuel connector 16.
- the rounded edge 25 of the annular support element 24 faces the contact surface 22 of the inner collar 18.

- the annular support element 24 also has an annular recess 26.
- the annular recess 26 is designed to be open inwards. This means that the annular recess 26 is designed to be open towards the fuel connector 16.
- An elastically deformable element 27 is partially inserted into the annular recess 26.
- the elastically deformable element 27 is thus indirectly supported on the inner collar 18.
- the elastically deformable element 27 can, however, also be supported directly on the inner collar 12 of the connection piece 9.
- annular element 30 is provided which is connected to the fuel connection 16 via a weld 31.
- the annular element 30 can also be designed as a snap ring 30 or be connected to the fuel connector 16 in some other way.
- a support surface 32 is configured on the annular element 30. In a modified embodiment, however, the support surface 32 can also be configured directly on the fuel connection 16, in particular a collar of the fuel connection 16.
- annular angle element 33 is provided that has an L-shaped profile into which the elastically deformable element 27 is partially inserted.
- the elastically deformable element 27 has a rectangular, in particular square, profile and is configured in the shape of a ring. The elastically deformable element 27 is thus arranged between the annular angle element 33 and the annular support element 24.
- the elastically deformable element 27 is therefore supported by means of the annular angle element 33 on the support surface 32 of the annular element 30.
- the elastically deformable element 27 is thus indirectly supported on the support surface 32 of the ring-shaped element 30.
- the elastically deformable element 27 can also be supported directly on the support surface 32 of the annular element 30.

- a material connection between the annular element 30 and the fuel connector 16 is formed via the weld seam 31.
- a positive connection can also be provided.
- Other connection options are also conceivable.
- the fuel connector 16 is thus supported on the inner collar 18 of the connection piece 9 at least via the elastically deformable element 27.
- a direct contact between the connection piece 9 and the fuel nozzle 16 is avoided here. This significantly dampens vibrations.
- An elastic mounting of the fuel injector 17 can therefore be realized in an advantageous manner.
- the elastically deformable element 27 can be realized here by a wire mesh, a plate spring, a special spring or in some other way.
- the elastically deformable element 27 can be designed in such a way that it also acts as an angle tolerance compensation element 27.

- the U-shaped connecting bracket 47 is oriented perpendicular to the longitudinal axis 23 of the receiving space 15. This means that the two arms 46, 48 lie in a plane which is oriented perpendicular to the longitudinal axis 23.
- connection piece 9 is thus connected to the connection body 5 via the U-shaped connecting bracket 47.
- connection piece 9 is designed as a cup-shaped connection piece 9.
