- the present invention relates to a preassemblable assembly of a fresh air system for an internal combustion engine, in particular of a motor vehicle.
- the invention also relates to a fresh air system equipped with at least one such assembly.
- Internal combustion engines in particular in motor vehicles, have a fresh air system, which as a rule have a distributor space from which individual fresh air ducts emanate to combustion chambers of cylinders of the internal combustion engine. Furthermore, modern internal combustion engines have a fuel injection system that inject fuel with injectors directly into the combustion chambers of the cylinder or in the aforementioned, leading to the combustion chambers fresh air ducts. To operate the injectors or injectors electrical wiring is required, the power lines and / or signal lines for driving or for operating electrical coils and the like. The assembly of internal combustion engines is comparatively expensive, especially when individual components for maintenance purposes to be accessible or easily disassembled.
- the present invention is concerned with the problem of pointing for an internal combustion engine a way for a simplified structure, which is characterized in particular by an inexpensive manufacturability and / or easy maintenance.

- the electric unit has an electric coil for actuating a fuel injection valve for a plurality of cylinders of the internal combustion engine.
- the electrical unit comprises an electrical wiring for actuating the coils. It has a plurality of mutually parallel oriented, each one of the coils coaxially penetrating plug openings.
- the electrical unit has a plastic body which is molded onto the coils and to the wiring.
- the fuel unit for each coil has a tubular connecting piece for receiving in each case an injection valve.
- the fuel unit comprises a distributor housing which contains a fuel distributor chamber which has connection openings and to which the connection nozzles are welded or soldered in such a way that they are aligned parallel to one another and communicating with the distributor space.
- the fuel unit and the electrical unit are matched to one another such that, for mounting purposes, the connecting pieces of the fuel unit can be inserted coaxially into the plug openings of the electrical unit.
- the two independently independent, separately preassembled units can be assembled to form an assembly, which then comprises the electrical components and the fuel components and which can be completely pre-assembled independently of the fresh air system.
- the assembly process can be simplified as a whole.
- the electrical unit for each coil has a tubular body which is arranged coaxially to the respective coil, which protrudes on a side remote from the fuel unit in the mounted state with an end portion of the plastic body and forms a portion of the associated plug-in opening ,
- the connecting pieces are dimensioned so that they extend in the assembled state through the respective plug-in opening and protrude in particular over the end portion of the respective tubular body.
- FIG. 1 is a perspective view of a pre-assembled assembly
- Fig. 3 is a perspective view as in Fig. 1, but in transparent
- FIG. 5 shows a simplified cross section of a fresh air system in the region of an assembly mounted thereon
- Fig. 6 is a greatly simplified longitudinal section through a connecting piece in a preferred embodiment.
- a preassemblable subassembly 1 comprises a fresh air system 2 of an internal combustion engine, which is partially shown in FIG can be located in particular in a motor vehicle, an electrical unit 3 and a fuel unit 4.
- the assembly 1 is completely pre-assembled and can be grown according to FIG. 5 to the fresh air system 2. It forms with respect to the fresh air system 2 a separately producible unit.
- the electric unit 3 has for several, not shown here cylinder of the internal combustion engine in each case an electric coil 5, by means of which a fuel injection valve, not shown here in each case can be actuated.
- the electric unit 3 comprises four coils 5.
- the electrical unit 3 also includes an electrical wiring 6, with the aid of the coils 5 can be actuated.
- the wiring 6 comprises a plurality of lines 7 and expediently a common electrical plug connection 8.
- the electric unit 3 is also equipped with a plastic body 9, which is shown transparent in FIGS. 3 and 4, around the components of the electrical unit accommodated therein or embedded therein 3 to better represent.
- the plastic body 9 is molded onto the coils 5 and to the wiring 6.
- all the coils 5 and all lines 7 are thereby completely enveloped by the plastic of the plastic body 9, in particular also the plug connection 8, apart from a plug-in side.
- the electrical unit 3 also has coaxially with each coil 5 an insertion opening 10 which passes through the respective coil 5 coaxially.
- the plug-in openings 10 are arranged with respect to their longitudinal central axes 11 parallel to each other or parallel to each other.
- the fuel unit 4 has for each coil 5 a tubular connecting piece 12, which is designed to receive in each case an injection valve.
- the fuel unit 4 also has a distributor housing 13 which contains or surrounds a fuel distributor chamber 14 which can be seen in the sectional representation of FIG. 5.
- the distributor housing 13 has a connection piece 12 for each Connection opening 15.
- the connecting pieces 12 are fastened directly to the distributor housing 13, in each case in the region of one of the connection openings 15, in particular by welding or soldering.
- the connecting pieces 12 may also be glued to the distributor housing 13 or formed integrally thereon, in particular in a production of plastic.
- the connecting pieces 12 are aligned parallel to each other. Their longitudinal central axes 16 thus extend parallel to each other. In the inserted state, the longitudinal center axes 11 of the staking openings 10 coincide with the longitudinal center axes 16 of the connecting stubs 12.
- the fuel unit 4 and the electric unit 3 are mounted on each other, such that the connecting pieces 12 are respectively inserted coaxially into the insertion openings 10.
- the electrical unit 3 also has at least one tubular body 17 for each coil 5. This is arranged coaxially to the respective coil 5 and is in the mounted state on a side facing away from the fuel unit 4 side or on a housing 18 of the fresh air system 2 side facing away with an end portion 19 from the plastic body 9.
- the respective tubular body 17 forms a portion of the respective plug-in opening 10.
- the connecting pieces 12 are now, in particular in terms of their axial length, dimensioned so that they hineinerarranged in the assembled state into the end portion 19 of the tubular body 17.
- the connecting pieces 12 extend through the respective plug-in opening 10 and are even axially projecting beyond the end section 19 of the respective tubular body 17.
- the electric unit 3 also comprises molded on the plastic body 9 or trained seating areas 20. These are each arranged coaxially with one of the plug openings 10. If the electrical unit 3 or the module 1 as in 5 is attached to the housing 18 of the fresh air system 2, said seating areas 20 each cooperate with a complementarily shaped counter seating area 21 formed on the housing 18.
- the respective seat region 21 encloses in each case a fuel injection port 22 which, in the example, passes over a fuel injection channel 23 into a fresh air channel 24 of the housing 18 or the fresh air system 2.
- fuel can flow directly from the fuel valve or from the associated connecting piece 12 into the injection channel 23 when the injection valve is inserted into the respective connecting piece 12, without the fuel coming into contact with a component of the electrical unit 3.
- the tubular body 17 of the electric unit 3 may be arranged coaxially with one of the seating areas 20, respectively, according to the preferred embodiment shown here. Furthermore, they each carry at their projecting end portion 19 a ring seal 25.
- the respective end portion 19 may be equipped with a radially projecting circumferential collar 26 for this purpose.
- the respective ring seal 25 immersed in the installed state in the seat portion 21 and there causes a radial seal between the injection channel 23 and the end portion 19. In this way, on the one hand a false air intake and on the other a fuel emission can be avoided.
- the tubular body 17 is in each case designed such that it has a support section 27 arranged in the interior of the plastic body 9, which encloses the respective coil 5.
- electrical connections can be formed on this support section 27, which on the one hand electrically contact the coil 5 arranged in the interior of the support section 27 and, on the other hand, the lines 7 extending outside the support section 27.
- the fuel unit 4 is also equipped with an inlet pipe 28, which is attached to the distributor housing 13.
- the supply pipe 28 is welded or soldered to the distributor housing 13.
- the manifold 28 is communicatively connected to the distribution chamber 14.
- the supply pipe 28 leads to a fuel pump.
- the assembly 1, for example, by means of webs 29 are attached to the housing 18 of the exhaust system 2.
- these webs 29 have through openings, which allow a screwing of the assembly 1 to the housing 18.
- the webs 29 are attached to the fuel unit 4, and preferably attached to the distributor housing 13, for example, welded thereto or soldered thereto.
- the electrical unit 3 thereby fixed exclusively by a plug connection to the housing 18, but not directly attached thereto.
- the fuel unit 4 is fixed by a plug connection to the electric unit 3, but not directly attached thereto. Via the webs 29, a fixation of the fuel unit 4 is now achieved on the housing 18, which indirectly also a fixation of the fuel unit 4 to the electric unit 3 and a fixation of the electric unit 3 is realized on the housing 18.
- connection stubs 12 can contain a latching safety device 30, which is designed such that an injection nozzle which is inserted axially into the connection stub 12 engages with sufficient insertion depth.
- the latched on the latching fuse 30 injection nozzle is then axially secured in the connection piece 12. That is, the respective injection nozzle can not be easily pulled out of the connection piece 12 axially.
