Definitions

  • Figures 1 and 3 show three different embodiments of the sealing of the valve seat 16 with respect to the intake pipe 3 and another cylinder head module.
  • an axial seal 28 is shown, which is introduced at the lower end face 29 of the valve seat 16 in a sealing groove 32.
  • the seal 28 is designed with a round or rectangular cross-section.
  • the valve seat 16 is widened by the introduction of such an axial seal 28 flange.
  • a Axialeinstich 30 in the groove bottom of the seal groove 32 is useful.
  • Figure 4 shows a relation to Figures 1 and 3 rotated by 90 ° view of the fuel injection system, in which an electrical connection option of the fuel injection valve 1 is illustrated.
  • the valve seat 16 has, in the region of its flattened outer contour, a lateral recess 40, through which the electrical contacting of the fuel injection valve 1 takes place.
  • the electrical contacting of the individual fuel injection valves 1 via a contact rail 41, which connects all fuel injectors 1 together.
  • the contact rail 41 made of plastic, in which all necessary electrical lines are integrated, represents an elongated flat plate.
  • the z. B. is five-pin designed to be contacted fuel injectors 1, attached.
