Definitions

  • Fuel distributors are used on internal combustion engines, which serve to accommodate injection valves, via which the individual combustion chambers of the internal combustion engine are supplied with fuel. The aim is for the fuel to be distributed as evenly as possible to the individual injection valves, which should be valid both for conventional fuel supply systems and for return-free fuel supply systems.
  • Injectors used on fuel rails are retrofitted to the fuel rail by safety clips. Then the injection valves are electrically contacted via individual plugs from the wiring harness of the internal combustion engine.
  • DE 37 25 980 A1 relates to a device for making electrical contact with electromagnetically actuated fuel injection valves.
  • the individual plugs assigned to each fuel injection valve are arranged on a common contact strip.
  • the common contact strip can be fastened to the internal combustion engine by means of screws.
  • the common contact strip is to be connected to the electronic control unit via a cable harness.
  • DE 39 07 764 A1 relates to a fuel distributor for fuel injection systems of internal combustion engines.
  • This comprises at least one fuel injection valve and a valve carrier, which has at least one axially open one and with a fuel supply line connected stepped receiving bore for the fuel injector.
  • the receiving bore is surrounded by an end flange on which the fuel injection valve is axially supported by means of a collar element.
  • the end flange of the valve carrier and the collar of the fuel injection valve are designed as corresponding parts of a bayonet catch.
  • DE 43 25 980 A1 relates to a device for the common electrical contacting of several electrically excitable units on internal combustion engines.
  • the device for common electrical contacting of several units comprises contact pins for electrical contacting. Furthermore, a printed circuit board is provided, which runs over all units and is provided with a housing protecting the printed circuit board, which extends in the longitudinal direction of the printed circuit board and at least partially surrounds it.
  • the plurality of electrically excitable units in particular electromagnetically actuated fuel injection valves, are connected directly to the conductor tracks of the printed circuit board via the contact pins, the printed circuit board comprising elastic expansion loops for length compensation.
  • the contact pins of the units are inserted into contact pin receiving openings in the printed circuit board and connected to the conductor tracks by welding.
  • DE 195 46 441 A1 discloses a fuel distributor for fuel injection systems of internal combustion engines, with which at least two fuel injection valves are supplied.
  • the fuel distributor contains a fuel supply channel with a number of valve receptacles corresponding to the number of fuel injectors to be supplied.
  • the valve receptacles comprise valve receptacle openings which are directly connected to the fuel supply channel and into which the fuel injection valves can be inserted in such a way that the valve receptacles at least partially surround the fuel injection valves.
  • Electrical lines for the electrical contacting of the at least two fuel injection valves in the fuel distributor designed as a molded plastic part are integrated directly into the latter, the electrical lines being encased in plastic over most of their extent.
  • the electrical lines run in the form of flat strips in the fuel distributor.
  • the electrical lines run largely along the longitudinal extent of the fuel distributor, ie along the fuel supply channel, each electrical line having an angled course in the region of a valve receptacle in order to be supplied to contact elements of the fuel injection valves.
  • the solution proposed according to the invention allows the injection valve function group to be integrated into the fuel distributor function group, without the need for assembly components, such as securing terminals or individual plug connections to the individual injection valves.
  • the injection valve function group is integrated into the fuel rail function group, the geometry of the respective assembly is not changed.
  • the electrical and hydraulic contacting can now be carried out with the saving of several intermediate steps, so that a rationalization of the production of fuel supply lines with fuel distributors can be achieved.
  • the method proposed according to the invention further reduces the fuel permeation through the connection point between the fuel distributor and the injection valve assembly, since this is now taken up directly on the fuel distributor component either via a material connection or by encapsulation of the sealing ring with a flared material connection.
  • the integration of the injection valve assembly directly into the fuel distributor component also leads to an increase in the rigidity of the fuel distributor and thus to a better dynamic behavior of the fuel distributor in the event of vibrations and vibrations which inevitably occur during operation of a motor vehicle.
  • material savings can also be achieved in that partial wiring harnesses and individual feeder connections to the individual injection valves of the internal combustion engine in the cylinder head area can be dispensed with.

  • the valve body of the injection valve 2.1 is connected to the fuel distributor 1 in a material or positive connection, so that an improvement or a reduction in the fuel permeation can be achieved by connecting the injection valves directly to the fuel distributor 1.
  • FIG. 3 shows a fuel meter in longitudinal section with several injection valves integrated in it.
  • the fuel distributor 1 which can be made of plastic, for example, contains a cavity 12 which can be filled with fuel via a connection 23 to a fuel reservoir (not shown here) or a fuel pump via an interposed filter element 24.

  • the integral connection 18 can be produced, for example, by ultrasonic welding, for which purpose a special connection geometry of the fuel distributor 1 and the injection valve body 22 in the form of an annular projection 21 is to be provided.
  • the injection valve 2.1 is electrically contacted by moving the lead frame 17 accommodated in the connector receptacle 16 into one another with the connector tabs 19 protruding from the injection valve body 22 (cf. detailed illustration in FIG. 3.2) ).
  • the fuel entering via the connection 23 flows through the through bore 4 in the direction of the injection valve 2.1, wherein several injection valves 2.1 or 2.2 or 2.3 can be integrated into a fuel distributor 1 perpendicular to the plane of the drawing shown in FIG. 3.1 ,
  • FIG. 3.2 shows the electrical contacting of the injection valve on an enlarged scale.
