  • statically compressed fuel is stored in a pressure accumulator tube and distributed to the injectors or injection valves of a cylinder bank.
  • the DE 295 21 402 U1 discloses a fuel rail in which the tubular body of the accumulator tube is formed by forging with forged technically molded connection piece. On the connecting piece diametrically opposite lateral surface of the tubular body fasteners are formed. The fasteners form eyelets in which through holes are made by drilling.
  • the DE 10 2011 079 075 A1 discloses a fuel rail with a pressure accumulator tube, which has a tubular body with a longitudinal cavity and at least one connecting piece or an injector receptacle.
  • a pressure accumulator tube which has a tubular body with a longitudinal cavity and at least one connecting piece or an injector receptacle.
  • the connecting straps are located to the side of the pipe body.
  • the accumulator tube is preferably made by forging.
  • the pressure storage tubes are exposed to high loads. This also applies in particular to the area of connection of the pressure storage tubes to the cylinder head of an internal combustion engine.
  • the mounting points of the fuel rail on the engine block are specified by the manufacturer and vary from model to model.
  • moments are introduced into the connection.
  • the attachment between pressure accumulator tube and cylinder head is particularly difficult if it has to be inclined at an angle. As a result, the fastening means are additionally loaded.
  • EP 2 667 011 A2 includes a fuel rail to the prior art, which has a pressure accumulator tube for receiving pressurized fuel.
  • the pressure accumulator tube has a forged tube body on which injector attachment portions and bolt attachment portions are formed.
  • the pressure accumulator tube can be fixed via the bolt fastening sections by means of fastening screws on the cylinder head of an internal combustion engine.
  • a fuel rail with a pressure accumulator tube for receiving pressurized fuel can be fixed on the holder by means of fastening screws on the cylinder head of the internal combustion engine.
  • the holder can be made by casting or forging technology.
  • the holder is a sheet metal component. Both the holder and the Injektoritn are separate components which are joined to the pressure accumulator tube of the fuel rail.
  • the invention is based on the prior art, the task of creating a weight-optimized, production and assembly technology advantageous and improved in load behavior fuel distributor.
  • the fuel rail has an accumulator tube for receiving pressurized fuel.
  • the accumulator tube has a forged tubular body with a longitudinal cavity.
  • the longitudinal cavity usually has a circular cross-section.
  • Uniformly integrally formed on the tubular body support-shaped injector and supports are formed. The supports serve to fix the accumulator tube to a cylinder head of an internal combustion engine.
  • the accumulator tube is forged from a blank.
  • the material used is in particular a stainless steel alloy of the type 1.4307 or 1.4301.
  • the supports are formed in alignment with the injector receptacles on the tubular body.
  • This embodiment enables a forging technology production of the pressure storage tube, the forging blank is process reliably forgeable including the material uniformly integrally formed on the tubular body Injektoritn and the supports.
  • the supports are executed on the forging blank in an axis with the injector receivers within the parting plane of the forging tool. After forging, there is a mechanical processing, in particular a machining of the forged component, including the production of the holes for the longitudinal cavity in the tubular body and the connection holes in the Injektoritn.
  • the supports are aligned with the Injektoritied to this provided below the tubular body.
  • Below the tubular body means with respect to the mounting position of the pressure accumulator tube on the cylinder head that the supports point from the tubular body in the direction of the cylinder head.
  • a support has a leg section extending from the tubular body and, at its cylinder head end, a flange section with a passage for passing through a fastening screw.
  • the flange portion is located at the free end of a support, so it is displaced close to the region of the connection to the cylinder head. This shortens the span length of the fixing screws used to fix the fuel distributor on the cylinder head.
  • the support has, in particular in its leg portion, a recess extending in its longitudinal direction.
  • the recess is machined in the support, in particular the recess is milled out in the support.
  • the recess forms a free space for mounting the fastening screws.
  • the recess is located in the inner region of the support and ends at the flange portion. Cylinder head side, the recess is bounded by a clamping surface of the flange. The clamping surface is arranged on the side facing away from the cylinder head of the flange. At her lies the screw head of a fastening screw.
  • An essential aspect of the invention is that the screwing takes place via the flange section close to the connection region or the area of fixing the supports to the cylinder head. For this comparatively short screws can be used.
  • the installation of the mounting surface down to the cylinder head also reduces the compliance of the mounting screws.
  • the flange portion has a support surface adapted to the outer contour of the cylinder head.

  • the fuel distributor according to the invention reliably withstands deformations as a result of bending alternating stresses from operational, static and dynamic loads.
  • the fuel distributor is weight-optimized.
  • An advantageous and stress-optimized effect is when a support is arranged in each case between two injector receptacles in the longitudinal direction of the tubular body.
  • the overall functionality of the fuel distributor is further increased when integrally formed on the tubular body in one piece at least one, usually more coupling pieces for attachment of attachments.
  • the coupling pieces can serve, for example, for receiving sleeves and screw connection means, via which further system components, for example an intake module, can be mounted on the fuel distributor.
  • the fuel rail 1 belongs to the accumulator injection system of an internal combustion engine.
  • the pressure generation and the fuel injection are decoupled from each other in such storage injection systems.
  • a separate high-pressure pump continuously generates pressure. This pressure, which is built up independently of the injection sequence, is permanently available in the fuel distributor 1.
  • the fuel distributor 1 comprises a pressure accumulator tube 2 with a pump-side fuel inlet 3 and a plurality of injector ports 4, 5.
  • the statically compressed fuel is stored in the pressure accumulator tube 2 and distributed through the injector ports 4, 5 the injectors of a cylinder bank available.
  • the pressure accumulator tube 2 has a forged tubular body 6.

  • the longitudinal axes L1 of the supports 11 and the longitudinal axes L2 of the Injektoritn 4, 5 coincide.
  • supports 11 and injector 4, 5 allows an advantageous forging technology production of the tubular body 6.
  • Supports 11 and injector 4, 5 are arranged together in the parting plane of the forging tool or the forging tool halves and oriented rectified. As a result, the risk of tool breakage or cracks and folds in the forged supports 11 is counteracted.
  • Each support 11 has a leg portion 12 extending from the tubular body 6 and, at its cylinder head end 13, a flange portion 14 with a passage 15 for the passage of a fastening screw 16.
  • a leg portion 12 extending from the tubular body 6 and, at its cylinder head end 13, a flange portion 14 with a passage 15 for the passage of a fastening screw 16.
  • In the supports 11 and in the leg portion 12 of the supports 11 is in each case one in the longitudinal direction of the support 11 extending recess 17 is provided. This is machined by milling incorporated into the supports 11.

With the support surface 20 of the flange portion 14 abuts the cylinder head 10.
  • mounting screws 16 For mounting or fixing the fuel rail 1 on the cylinder head 10 short mounting screws 16 can be used. As a result, the flexibility of the screws 16 and thus in the screw connection is also reduced overall.
  • the fastening screws 16 are screwed via the recess 17 and the passages 15 into corresponding threaded bores in the cylinder head 10. In this case, the screw heads 19 come to rest on the clamping surface 18 of the flange section 14.
  • the support surface 20 of the flange portion 14 is particularly oblique. As a result, the area of the system between the flange portion 14 and the cylinder head 10 can be increased and thus the surface pressure can be reduced.
  • the outer contour of the cylinder head 10 is inclined correspondingly obliquely in the connection region of the fuel rail.
  • the screw axis L3 extending in the longitudinal direction of a fastening screw 16 and the longitudinal axis L1 of a support 11 extend at an angle ⁇ at an angle to one another.
