Definitions
- the invention is based on a fuel injection valve according to the preamble of claim 1 and a method for Setting a fuel injector after Genus of claim 9.
- a comparable fuel injector is known for example from DE 41 23 787 A.
- DE 40 23 828 A1 describes a setting method a fuel injector and a Fuel injector known.
- Medium flow rate of an electromagnetically actuated Fuel injection valve is placed in a blind hole changing magnetic properties of the inner pole magnetically conductive material, for example in the form of a powder and thus the magnetic force varies until the measured actual flow rate of the medium matches the specified target quantity.
- DE 40 23 826 A1 proposed a alignment bolt in a blind hole Inner pole, which has a recess on its circumference, so far insert and thus vary the magnetic force until the measured actual quantity with the specified target quantity matches.
- DE 195 16 513 A1 also describes a method for Setting the dynamic flow rate of a medium Fuel injector known.
- One finds Adjustment of an adjusting element that is close to the Magnet coil arranged outside the medium flow path is.
- the size of the magnetic flux changes in the magnetic circuit and thus the magnetic force, so that the Medium flow rate can be influenced and adjusted.
- the Adjustment can be made both when wet and when dry fuel injector.
- DE 42 11 723 A1 describes a fuel injection valve or a method for adjusting the dynamic Medium flow quantity of a fuel injector proposed, in which a longitudinal slot Adjustment sleeve up to a predetermined press-in depth a longitudinal bore of a connecting piece is pressed in, the dynamic actual volume of the valve measured and with compared to a medium target quantity and the injected, under a tension acting in the radial direction Adjustment sleeve is pushed in until the measured Actual medium quantity with the specified medium target quantity matches.
- a disadvantage of the group of mechanical adjustment methods is particularly the high degree of inaccuracy of these procedures subject.
- the opening and closing times a fuel injector only at the expense of shorten electrical power, thereby reducing the electrical Load on the components increases and the control units be stressed more.
- the fuel injector according to the invention with the characterizing features of claim 1 and that Method according to the invention with the characteristic features of claim 9 has the advantage that eccentric holes in the bottom of the adjusting sleeve and in the inner sleeve used to adjust the static Flow depending on the desired amount of fuel to different degrees to a resulting Aperture cross section can be covered without the setting of the dynamic To influence flow and vice versa.
- adjusting sleeve and Inner sleeve are simple and inexpensive to manufacture.
- the inner sleeve is advantageously in the adjusting sleeve fixed with a snap ring, causing an adjustment the inner sleeve and thus a change in the resulting Aperture cross section during operation of the Fuel injector is avoided.
- the static The flow rate is set safely.
- the possibility of static is particularly advantageous Flow rate based on a preset middle aperture cross-section both by an enlargement of the aperture cross section to an unthrottled Increase maximum value as well as decrease the Reduce the aperture cross-section to almost zero.
- Fuel injector 1 is in the Form of a fuel injector 1 for Fuel injection systems from mixture-compressing, spark-ignition internal combustion engines.
- the Fuel injection valve 1 is particularly suitable for not directly injecting fuel into one Shown combustion chamber of an internal combustion engine.
- the fuel injector 1 consists of a Nozzle body 2, in which a valve needle 3 is arranged.
- the valve needle 3 is operatively connected to a Valve closing body 4 with one on one Valve seat body 5 arranged valve seat surface 6 into one Sealing seat interacts.
- the fuel injection valve 1 in the exemplary embodiment it is an inward opening fuel injector 1, which has a Spray opening 7 has.
- the nozzle body 2 is through a Seal 8 against an outer pole 9 of a magnet coil 10 sealed.
- the magnet coil 10 is in a coil housing 11 encapsulated and wound on a bobbin 12, which bears against an inner pole 13 of the magnet coil 10.
- the Inner pole 13 and outer pole 9 are through a constriction 26 separated from each other and not by one another ferromagnetic connecting member 29 connected.
- the Solenoid 10 is connected via a line 19 from one to the other an electrical plug contact 17 feedable electrical Current excited.
- the plug contact 17 is one Surround plastic sheath 18 on the inner pole 13th can be
- the valve needle 3 is in a valve needle guide 14 led, which is disc-shaped.
- a paired shim 15 is used for stroke adjustment the other side of the shim 15 is the Anchor 20.
- This stands over a first flange 21 non-positively in connection with the valve needle 3, which through a weld seam 22 with the first flange 21 connected is.
- One is supported on the first flange 21 Return spring 23, which in the present design of the Fuel injection valve 1 through an adjusting sleeve 24 Bias is brought.
- the position of the adjusting sleeve 24 is for the bias the return spring 23 and thus for the dynamic Flow rate through the fuel injector 1 responsible.
- Inner sleeve 34 is provided, which in the adjusting sleeve 24th is inserted.
- the inner sleeve 34 is cup-shaped formed and has in a bottom 35 of the inner sleeve 34 an eccentric bore 36.
- the adjusting sleeve 24 is is also pot-shaped and is in a bottom 37 the adjusting sleeve 24 also with an eccentric Provide hole 38. Eccentric holes 36 and 38 are attached so that they are made to coincide can be.
- FIGS. 2 and 3 A detailed description of the measures according to the invention and the functioning of Inner sleeve 34 is FIGS. 2 and 3 and the following See description.
- valve needle guide 14 in the armature 20 and on Valve seat body 5 run fuel channels 30a to 30c.
- the fuel is supplied via a central fuel supply 16 supplied and filtered by a filter element 25.
- the Fuel injector 1 is against by a seal 28 a fuel line, not shown sealed.
- a annular damping element 32 On the spray side of the armature 20 is a annular damping element 32, which consists of a Elastomer material is arranged. It's on one second flange 31, which has a weld seam 33 is non-positively connected to the valve needle 3.
- Fig. 2 shows that in an excerpted sectional view in Fig. 1 designated II detail of the invention designed fuel injector 1 without that Filter element 25, which in Fig. 1 in the central Fuel supply 16 is arranged.
- the adjusting sleeve 24 has a bottom 37 with an eccentrically arranged bore 38.
- an inner sleeve 34 which is also pot-shaped with a bottom 35, in an eccentric bore 36 is attached.
- the Inner sleeve 34 is dimensioned so that it means a snap ring 39 can be fixed in the adjusting sleeve 24.
- the adjusting sleeve 24 is slotted accordingly executed to the assembly of the inner sleeve 34 with the Allow snap ring 39.
- the flow rate is set accordingly against the holding force of the snap ring 39.
- the eccentric holes 36 and 38 are so in the bottoms 35 and 37 aligned that they have a common axis exhibit.
- the inner sleeve 34 has an engagement surface 40 for a corresponding tool, for example a polygon, by means of which the inner sleeve 34 is rotatable.
- the adjusting sleeve 24 is first so far pressed into the fuel injector 1 until a corresponding tension of the return spring 23 desired value of the dynamic flow has been reached.
- the static flow rate is between one unthrottled value with complete overlap of the Holes 36 and 38 and a minimum value at an almost closed aperture cross section 41 variable.
- This arrangement is particularly advantageous Possibility of static and dynamic flow through fuel injector 1 independently of each other adjust so that the steps described above can also be carried out in reverse order.
- Fig. 3 is a cross section through the adjusting sleeve 24 and the inner sleeve 34 shown, the section along the Line III-III in Fig. 2 is guided.
- the aperture cross section 41 can be changed at any time possible by removing the filter element 25 from the fuel supply 16 is removed and the inner sleeve 34 opposite the Adjusting sleeve 24 rotated with a suitable tool becomes.
- the fuel injector 1 does not need to be expanded in its entirety, components still need from the fuel injection valve 1 for setting the Flows are removed.
