Definitions

  • a common rail injector fuel injector formed with the fuel supply components is shown schematically in longitudinal section.
  • the fuel injector comprises a holding body 1 and a nozzle body 2, which are clamped together by a clamping nut 3.
  • a two-part injection valve element 3 is mounted longitudinally displaceable.
  • the injection valve element 3 consists of a Nozzle needle 4, which is arranged longitudinally displaceably in the nozzle body 2 and a control rod 5, which is arranged longitudinally displaceable within the holding body 1.
  • the nozzle needle 4 controls the opening of at least one injection opening 6 by its longitudinal movement.
  • the fuel is supplied to the injection openings 6 from the nozzle chamber 7, which surrounds the nozzle needle 4 and which can be filled with fuel at high pressure via an inlet channel 8. If the nozzle needle 10 moves away from the injection openings 6 and thus moves into its open position, fuel, essentially under rail pressure, is injected from the nozzle chamber 7 via the injection openings 6 into a combustion chamber of an internal combustion engine, not shown in the drawing. If, however, the nozzle needle 10 is in its closed position, i. in contact with a valve seat, the openings 6 are closed by the nozzle needle 4.
  • a high-pressure pump 13 For supplying the fuel under high pressure, a high-pressure pump 13 is provided, which compresses the fuel from a reservoir 14 and a high-pressure accumulator 15 (Rail) supplies, in which the fuel is kept under high pressure. Via a high-pressure line 16 and a high-pressure port 17, which is formed on the fuel injector, the fuel under high pressure is supplied to the fuel injector and injected in the manner described via the injection openings 6 into the combustion chamber of the internal combustion engine.
