Definitions

  • the invention relates to a device according to the preamble of the main claim.
  • Fuel injection valves are already known in which the electrical contact is made by means of individual plugs which are successively plugged onto each assigned fuel injection valve.
  • Such connectors are known from document DE-A-3 220 090. This means a considerable effort in the assembly of the fuel injection valves on the internal combustion engine, since the fuel injection valves are first inserted into the individual openings provided on the individual intake pipes of the cylinders of the internal combustion engine and then by individual clamping claws, the fuel injection valves are axially fixed in these openings. Subsequently, the plug which is electrically conductively connected to the electronic control unit is plugged into each fuel injection valve.
  • the document US-A-4 570 601 discloses a device in which the supply of current to the fuel injection valves is carried out by means of a single contact strip. Both plug contact elements for contacting each individual valve and plug contact elements for connecting the control unit and electrical lines are mounted on this contacting strip. However, this device only discloses a contact strip that includes both power and fuel lines, which requires tighter tolerances.
  • the device according to the invention with the characterizing features of the main claim has the advantage that the electrical contacting of several fuel injection valves by means of the Contacting strip arranged plugs takes place simultaneously in one operation and, at the same time, a force can be exerted on the fuel injection valves in the axial direction, by means of which the fuel injection valves can be fixed in the axial direction.
  • the fuel injection valves can also be plugged into the plugs of the contact strip and then inserted together into the openings on the individual intake pipes or cylinders on the cylinder head of the internal combustion engine by means of the contact strip.
  • plugs from a first and second plug part and to connect the plug parts to one another such that one of the plug parts reaches through a plug opening in the contact strip and the contact strip is held between the two plug parts.

  • the contact pins 5 extend approximately in the direction of the longitudinal axis 6 of the fuel injection valve 1 and are electrically conductively connected to a magnet coil, not shown.
  • the contact pins 5 preferably have a rectangular cross section.
  • each Fuel injector 1 is assigned a connector 9.
  • the fuel injection valves 1 and the control unit 8 are components of a fuel injection system in which the quantity of fuel injected via the fuel injection valves 1 is dependent on the operating parameters of the internal combustion engine, such as intake air quantity 10, load 11, temperature 12 and others, which are input as a function of the electronic control unit 8.
  • the plugs 9 are arranged on a common contact strip 14, which can be made completely flat or, for example, have a trough-like shape according to the drawings and can be made of sheet metal.
  • an edge region 15 on the circumference of the entire contact strip is bent approximately at right angles to a flat inner region 16.
  • This bent edge region 1 can also only extend over a partial region of the circumference of the contact strip, for example only over one or both edge regions on the narrow sides of the contact strip or over one or both edge regions on the longitudinal sides of the contact strip 14.
  • the contact strip can be made of metal, plastic or Ceramic exist and has mounting holes 17 through which screws 18 can be inserted and screwed into the wall of the internal combustion engine for fastening the contact strip to the internal combustion engine.
