  • the invention is based on the object in the preamble of claim 1 fuel injector so to design that a simple constructive structure achieved becomes.
  • the fuel injector according to the invention has the advantage that the maximum stroke for pilot injection is simple constructive way is achieved.
  • Another advantage of the invention is that both in the pilot injection as well as in the main injection through an optimally adapted spray hole diameter the beam processing can be improved.
  • Figure 1 is the combustion chamber of an internal combustion engine protruding tip 10 of the nozzle body 12 of a fuel injection nozzle shown enlarged in section.
  • the top 10 of the nozzle body 12 are two axially spaced rows 14, 16 formed by injection holes through which the fuel from the nozzle body 12 under pressure in the combustion chamber of the Internal combustion engine is injected.
  • a nozzle needle 20 is arranged in the nozzle body 12 of the injection valve.
  • the nozzle needle 20 has on it Tip a conical surface 22 with which, if that Injector is closed, above the injection holes on the conical inside 24 of the tip 10 of the nozzle body 12 is applied so that no fuel from the interior 26 of the Nozzle body 12 reaches the injection holes.
  • the interior 26 is with a fuel line, in particular with a Fuel storage connected.
  • the nozzle needle 20 due to increased fuel pressure in the interior 26 of the nozzle body 12 and / or a control the fuel injector lifts off the valve seat, the conical inside 24 of the tip 10 of the nozzle body 12 for the conical surface 22 of the nozzle needle 20, the way for the fuel to the injection holes is cleared. The injection begins and continues until the Nozzle needle 20 back down on the valve seat in the Tip 10 of the injector moves too.
  • An insert body 30 is inserted into the tip of the nozzle needle 20.
  • the cone at the tip of the nozzle needle 20 is for this cut off at right angles to the axis of the nozzle needle 20, and the nozzle needle 20 has a cut off tip recess extending axially into the nozzle needle 20 on.
  • the relatively short insert body 30 is regarding the nozzle needle 20 inserted axially movable in this recess; it points one out of the nozzle needle 20 in the axial direction protruding cone body 32 and one located in the nozzle needle 20 Guide 34 on.
  • the insert body 30 is one Actuated spring 36, which is arranged in a recess 75 is and the insert body 30 in the axial direction from the nozzle needle 20 pushed out.
  • the insert body 30 has a radially circumferential second Pressure area 84 on the in the closed position of the insert body 30 at the level of the top row 14 of injection holes is arranged.
  • the shape of the second printing surface 84 corresponds essentially to an outward-facing one Cone shape.
  • the conical surface 22 of the nozzle needle 20 is in the closed state of the injection valve above the upper row 14 of injection holes on the conical inside 24 of the top 10 of the Nozzle body 12, that is in the direction of flow of the fuel in front of or above the first, upper row 14 of injection holes.
  • the axially from the nozzle needle 20th protruding insert body 30 lies with its conical body 32 between the upper row 14 and the lower row 16 of the Injection holes on the inside 24 of the tip 10 of the nozzle body 12, the insert body 30 by a distance a pressed against the action of the spring 36 in the nozzle needle 20 is.
  • the conical surface 22 rises the nozzle needle 20 by the one acting on the nozzle body 12 Fuel pressure from the inside 24 of the top 10 of the Nozzle body 12 from. If the conical surface 22 of the nozzle needle 20 begins to lift off from the inside 24 of the crest 10, remains due to the action of the spring 36 (and possibly additionally due to the rear of the cone body 32 acting fuel pressure) of the cone body 32 of the insert body 20 on the inner surface 24 in plant. The fuel can thus past the conical surface 22 only up to the top row 14 of the injection holes. About these injection holes the pilot injection takes place. During the pilot injection remains the lower row 16 of the injection holes closed. The shape of the second pressure surface 84 in this position of the insert body 30 ensures that the fuel spreads evenly on the injection holes top row 14 distributed.
  • the shoulder 38 on the insert body 30 comes to a stop 39 the nozzle needle 20 to the system.
  • the insert body 30 is subsequently carried along by the movement of the nozzle needle 20.
  • the cone body 32 thereby lifts from the inside 24 the top 10 of the nozzle body 12, so that the path of the Fuel to the second, lower row 16 of the injection holes becomes free. The main injection takes place via these injection holes.
  • the insert body is formed by the shape of the second pressure surface 84 30 by the flow of fuel caused thereby adjusted in the center so that misalignment is avoided. This causes an even supply of fuel for the injection holes of the lower row 16 when the insert body is lifted off 30th
  • the lower row 16 of the injection holes opens accordingly delayed, the extent of the stroke a or Movement of the insert body 30, which determines the deceleration, the pilot injection quantity can be dosed precisely.
  • the spray hole diameter can be used for both pilot injection as well the main injection is precisely adapted and thus the jet preparation be optimized.
  • the geometry is also preferred the injection holes of the upper row 14 to the pilot injection, which represents a pre-injection.
  • the geometry of the injection holes is preferably the lower row 16 adapted to the function of the main injection, the cross-section of the injection holes of the top Row 14 is smaller than the cross section of the injection holes the bottom row 16.
  • Figure 2 shows the overall structure of an injection valve for a Diesel injection system, which is designed as a common rail system is.
  • the nozzle body shown in Figure 1 is shown only schematically in FIG.
  • the nozzle needle 20 is in a second recess 76 in the nozzle body 12 out.
  • the upper end of the nozzle needle 20 is with a coupling rod 74 in connection.
  • the coupling rod 74 is arranged symmetrically in the injection valve.
  • the coupling rod 74 is in the lower area in a stop plate 51 performed, which also the maximum stroke H of the nozzle needle 20 sets.
  • the distance a is smaller than the maximum stroke H and thus distance a defines the maximum stroke of the nozzle needle 20 for the pre-injection.
  • the coupling rod 74 rests on a control piston 52 on, which is arranged in a piston recess 53.
  • the Control piston 52 is sealingly guided in the piston recess 53 and adjoins a control chamber 74 which has a Inlet throttle 55 with a high pressure line 50 and one Flow restrictor 56 communicates with a valve chamber 78.
  • the inlet throttle 55 has a smaller cross section than the flow restrictor 56 on.
  • a closing member 57 is arranged, which from a third spring 79 biased against a sealing seat 80 is.
  • the sealing seat 80 is at the entrance of a drain hole 59 formed, which connects the valve chamber 78 with a return 81.
  • the return 81 is, for example, with the fuel tank in connection.
  • a valve rod 58 is guided in the drain hole 59 is actuated by a piezo actuator 71.
  • the piezo actuator points Control lines 72 on which he from an engine control unit is controllable.
  • the injector works as follows: In the closed position, the piezo actuator 71 is not energized and the closing member 57 rests on the sealing seat 80, so that in the control chamber 54 has the same fuel pressure as in the high pressure line 50 that has a fuel accumulator communicates. The high pressure in the control chamber 54 presses over the control piston 52 and the coupling rod 74 Nozzle needle 20 on the valve seat on the inside 24. The Insert body 30 is also on the inside by the spring 36 24 pressed. In this position are the top and the lower row of injection holes 14, 16 closed.
  • the piezo actuator 71 is energized for the pre-injection. As As a result, the piezo actuator 71 expands and presses over the valve rod 58 the closing member 57 away from the sealing seat 80. Thus, fuel flows from the control chamber 54 through the drain throttle 56 from. At the same time flows through the inlet throttle 55 Fuel too. However, since the cross section of the inlet throttle 55 is smaller than the cross section of the discharge throttle 56, the fuel pressure in the control chamber 54 drops the force decreases from the control chamber 54 to the nozzle needle 20 acts. At the same time lies on a printing surface 82, which in the lower region of the nozzle needle 20 is formed, a high Fuel pressure on. The force on the pressure surface 82 acts the force emanating from the control chamber 54.
  • the force also acts on the second pressure surface 84 further lift off the nozzle needle 20 against the valve seat.
  • the nozzle needle 20 remains after the stroke with the Line a stand at shoulder 38 so that the bottom row remains closed by injection holes 16.
  • the piezo actuator 71 is energized longer, so the pressure difference between the control chamber 54 and the interior 26 is correspondingly large that the nozzle needle 20 with the insert body 30 lifted from the inside 24 and thus an injection over the top row 14 and the lower row 16 of injection holes.
  • the injection is stopped by the piezo actuator 71 is released and thus shortened and thus the closing member 57 again via the third spring 79 onto the sealing seat 80 is pressed and thus the sequence via the flow restrictor 56 is interrupted.
  • the nozzle needle 20 is at a maximum moves the stroke H up, which is determined by the game between the top of the nozzle needle 20 in Closed position and the lower stop surface of the stop plate 51 is present.
  • the nozzle needle is at maximum stroke H. 20 on the stop plate 51.
  • the maximum stroke for the pre-injection by the distance a between the shoulder 38 of the guide 34 and the stop 39 of the Nozzle needle 20 set, the nozzle needle 20 and the Insert insert 30 against inside 24.
  • FIG. 3 shows a further shape of the insert body 30 with a Ring recess 40.
  • the insert body 30 has a radial encircling ring recess 40 in the closed position of the insert body 30 at the level of the upper row 14 of Injection holes is arranged.
  • the shape of the ring recess 40 corresponds essentially to one towards the center of the insert body 30 directed cone shape.
  • the part of the cone surface is over the insert body from the surrounding fuel pressure down is pressed towards the inside 24, larger than the part of the cone surface that separates the nozzle needle from the surrounding one Pushes fuel pressure upwards from the inside 24.
  • the insert body is also in this embodiment 30 towards the inside 24 through the surrounding Fuel pressure depressed.
