Definitions
- a fuel distributor for fuel injection systems of internal combustion engines is known from WO 90-13740.
- This fuel distributor is usually a multifunctional component which carries the injection valves, is also provided with the corresponding electrical connections and has a feed for the fuel.
- the fuel rail is fastened to an intake pipe with screw connections, the electrical distribution list is also fixed with the corresponding screw connections. With appropriate security, such screw connections are extremely reliable, but the high installation effort and the associated high manufacturing costs.
- the invention is therefore based on the object of providing an intake pipe with a fuel distributor for supplying the fuel to an internal combustion engine, in which the assembly effort is considerably reduced. Starting from the preamble of the main claim, this object is achieved by the characterizing features thereof.
- the main advantage of the invention is that the fuel rail is fastened with a plug or snap or snap connection.
- the assembly is therefore possible without tools and can be carried out in a simple manner manually or automatically.
- the reliability of such a connection is further increased by the arrangement of an additional securing element.
- the securing element consists of a resilient, clamped securing pin. It is also possible to provide a self-tapping screw connection or to directly secure it via a snap-in connection on the fuel rail.
- Suitable O-rings can be provided for the liquid-tight connection between the intake pipe and the fuel distributor or the injection valve and the fuel distributor.
- Figure 2 is a plan view of a fuel rail
- Figure 3a-3i different variants of a connector for a fuel rail
- FIG. 1 it was known to attach a distributor pipe (10) to a suction pipe (20) with a screw connection (19).
- the injection valve (21) was inserted between the distributor pipe (10) and the intake pipe (20).
- this type of attachment is very complex since the intake pipe (20), which is normally made of plastic, additionally requires heat sink bushings (22), and spacer sleeves (23) are also necessary on the plastic distribution pipe.
- 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 attached to two connection elements (11, 12) of the intake pipe (17).
- the injection valves (13, 14) are shown between the fuel distributor and the intake manifold; spring clips (15, 16) are provided as a plug-in fuse.
- the fuel supply to the fuel distributor (10) takes place via the connecting 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) which is attached to a connecting element (11) of the intake pipe (17) and is held with a securing clip (15).
- FIG. 3c is also a securing clip, but the clip is not made of plastic according to FIGS. 3a and 3b but from spring steel (25) or bronze sheet.
- 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) which is also a positive connection for attaching the fuel rail to the intake manifold and is made of plastic, for example.
- 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).
- FIGS. 3h and 3i there is also the possibility according to FIGS. 3h and 3i to provide a snap or locking element (29, 30) on the connection element (11).
- a reliable connection between the fuel distributor and the intake pipe (17) or the corresponding connecting element (11) of the intake pipe is also achieved here.
- additional securing elements are omitted.
