Definitions

  • a fuel rail to supply the fuel to the to arrange appropriate injectors.
  • a fuel distributor is known from WO 90-13740 known for fuel injection systems of internal combustion engines.
  • This fuel rail is usually a multifunctional component that carries the injectors, also with the corresponding electrical connections are provided and a feed for the Has fuel.
  • the fuel rail is screwed to one Intake pipe attached, the electrical distribution list is also fixed corresponding screw connections. With appropriate backup, there are Screw connections are extremely reliable, but the high disadvantage Assembly effort and the associated high manufacturing costs.
  • the invention is therefore based on the object of an intake manifold To create fuel rail to supply the fuel to an internal combustion engine which the assembly effort is significantly reduced. This task will start from the preamble of the main claim solved by its characteristic features.
  • the main advantage of the invention is that the fuel rail with a plug or Snap or snap connection is attached.
  • the assembly is therefore without tools possible and can be done manually or automatically in a simple manner.
  • connection is according to a further embodiment of the Invention further increased by the arrangement of an additional securing element.
  • securing element consists of a resilient, clamped Locking pin.
  • a self-tapping screw connection to provide or immediate locking via a snap-in connection on the fuel rail to make.
  • Suitable O-rings can be provided for the injection valve and fuel rail.
  • FIG. 1 it was known to have a distributor pipe (10) with a screw connection (19) to attach an intake pipe (20). Between manifold (10) and intake pipe (20) the injection valve (21) was inserted.
  • this type of attachment is very complex because in addition to the intake pipe (20), which is usually made of plastic Heat sink threaded bushings (22) are required, and spacer sleeves (23) are also on the plastic distributor pipe is necessary.
  • FIG. 2 shows a plan view of a fuel rail with an example of a solution according to the invention.
  • the fuel rail (10) is on two connection elements (11,12) of the suction pipe (17). Are between the fuel rail and intake manifold the injection valves (13, 14) are shown, spring clips (15, 16) are used as a plug-in fuse intended.
  • the fuel supply to the fuel rail (10) takes place via the Connection piece (24), the fuel distributor (10) shown is a return-free system.
  • Figures 3a-3i show different variants of a connector.
  • FIGS 3a and 3b show a fuel rail (10) on a connecting element (11) of the Intake pipe (17) is attached and held with a securing clip (15).
  • FIG. 3c is also a securing clip, but that is Clip not made of plastic according to Figures 3a and 3b but from a spring steel (25) or bronze sheet manufactured.
  • the locking pin (26) is riveted to the clip.
  • Figure 3d shows a securing element with a self-tapping screw (28).
  • Figure 3e (section I-I of Figure 3a) and 3f each show a locking pin (18) also a positive connection for attaching the fuel rail to the Represents intake pipe and is made for example of plastic.
  • Figure 3g shows a pin element (27) which is made of spring tape or spring wire.
  • Figure 3d shows a securing element with a self-tapping screw (28).
  • connection element (11) To provide snap or locking element (29,30).
  • Fuel distributor (10) In conjunction with a counterpart on the Fuel distributor (10) is also a reliable connection of the fuel distributor here and intake pipe (17) or the corresponding connection element (11) of the intake pipe achieved.
