  • the flow of the spray orifices is, above all things, evened out and more stable over time. Flow fluctuations in the spray orifices can be reduced, leaving the overall spray pattern a quieter impression. As a result, a cleaner and better combustion of the fuel in the combustion chamber is achieved. Combustion misfires, which could occur in the case of certain jet patterns or interpretations of the injection orifices in known cases in extreme cases, can be excluded according to the invention here.

  • a sealing ring 2, in particular of Teflon®, ensures optimum sealing of the fuel injection valve 1 with respect to the wall of the receiving bore 20 of the cylinder head 9.
  • a flat intermediate element 24 is inserted, which is designed in the form of a washer.
  • the fuel injection valve 1 has at its inlet-side end 3 a plug connection to a fuel distributor line (fuel rail) 4, which is sealed by a sealing ring 5 between a connection piece 6 of the fuel distributor line 4, which is shown in section, and an inlet connection 7 of the fuel injection valve 1.
  • the fuel injection valve 1 is inserted into a receiving opening 12 of the connection piece 6 of the fuel distribution line 4.
  • the connecting piece 6 is in this case e.g. in one piece from the actual fuel distributor line 4 and has upstream of the receiving opening 12 a smaller diameter flow opening 15 through which the flow of the fuel injection valve 1 takes place.
  • the fuel injection valve 1 has an electrical connection plug 8 for the electrical contacting for actuating the fuel injection valve 1.
  • a holding-down device 10 is provided between the fuel injection valve 1 and the connecting piece 6.
  • the hold-down 10 is as a bow-shaped component executed, eg as a punching-bending part.
  • the hold-down device 10 has a part-ring-shaped base element 11, from which a hold-down bar 13 extends, which abuts against a downstream end face 14 of the connecting piece 6 on the fuel distributor line 4 in the installed state.
  • FIG. 2 is the discharge-side end 17 of the fuel injection valve 1 according to FIG. 1 is shown with a plurality of fürström Suiteen 26 in the nozzle body 18 in an enlarged view.
  • the fuel injection valve 1 has at least one excitable actuator (not shown), such as an electromagnetic circuit, a piezoelectric or magnetostrictive actuator, and a valve element movable along a valve longitudinal axis 27.
  • the valve element, not shown (valve needle, valve closing body) cooperates sealingly with a valve seat 28 which is formed, for example, at the downstream end of a blind hole 29 in the nozzle body 18 itself. Upstream of the valve seat 28, a plurality of through-flow regions 26 are formed in the wall of the blind bore 29 of the nozzle body 18.
  • flow-through regions 26 are formed in the form of flow-through pockets which allow the fuel to flow unimpeded to the valve seat 28 when the valve element is installed.
  • reference numeral 18 is intended in particular a fixed to a nozzle body valve seat body, as in eg FIG. 2 the DE 10 2006 049 253 A1 is meant to be meant.
  • FIG. 3 shows a sectional view taken along the line III-III of in FIG. 2 From this view, it is clear that the naturalström Societye 26 form leksnutähnliche flow pockets, which are spaced from each other.
  • a guide region 30 for the axially movable valve element lies between the flow-through regions 26.
  • five flow areas 26 are provided in the nozzle body 18.
  • Downstream of the valve seat 28 are in a bottom portion 31 of the nozzle body 18 or in an alternative spray perforated disk, which is fastened to the nozzle body 18, a plurality of ejection openings 32 is formed by the fuel atomized finely atomized into the combustion chamber 25 is discharged.
  • the spray-discharge openings 32 are, for example, oriented in such a way that they extend obliquely inclined radially outward beyond the thickness of the bottom section 31 or the spray-perforated pane.
  • the fürström Schemee 26 are thus at a regular average distance of 72 ° to each other and are incorporated with the same circumferential width and radial depth in the nozzle body 18. Due to the different number of fürström Schemeen 26 and spray openings 32 arise depending on the valve design instabilities in the flow of the spray openings 32. This can ultimately lead to a large divergence of the jet and flow characteristics disadvantageously. Due to the ambiguous and temporally not necessarily stable quantity allocation, it can also lead to a restless "fluttering" spray pattern.
  • FIG. 4 is a first embodiment of a fuel injection valve 1 according to the invention in the region of its nozzle body 18 in a representation analogous to FIG. 3 shown.
  • at least two flow areas 26 differ in their circumferential width.
  • the flow-through regions 26 are now changed in width so that, for example, wider flow-through regions 26 are designed so that they safely and reliably cover the quantity required for two spray-discharge openings 32, while the narrow flow-through regions 26 are reduced in size compared with the known ones Solution according to FIG. 3 are that a sufficient amount of fuel for exactly one ejection opening 32 is provided.
  • FIG. 5 is a second embodiment of a fuel injection valve 1 according to the invention in the region of its nozzle body 18 in a representation analogous to FIG. 3 shown.
  • at least two flow areas 26 differ in their radial depth.
  • the flow-through regions 26 are now changed in their depth so that, for example, deeper flow-through regions 26 are designed such that they reliably and reliably cover the quantity required for two spray-discharge openings 32, while the flow-through regions 26 having a small depth thus become smaller compared to the known solution according to FIG. 3 are that a sufficient amount of fuel for exactly one ejection opening 32 is provided.
  • the maximum depth of the fürström Schemee 26 is determined inter alia by the compressive strength of the nozzle body 18 at its downstream end 17.
  • FIG. 6 is a third embodiment of a fuel injection valve 1 according to the invention in the region of its nozzle body 18 in a representation analogous to FIG. 3 shown.
  • at least two flow areas 26 differ in their circumferential width and their radial depth.
  • this variant represents a combination of the two embodiments described above.
  • the flow areas 26 are now changed in width and depth so that, for example, wider and at the same time deeper or, on the one hand, wider and, on the other hand, lower flow-through areas 26 are designed in that they reliably and reliably cover the quantity required for two ejection openings 32, while the narrower and at the same time having a shallower depth or, on the one hand, narrow and, on the other hand, flat flow-through regions 26 are thus reduced in comparison with the known solution according to FIG. 3 are that sufficient Amount of fuel for exactly one spray opening 32 is provided. In this way, a uniform and temporally stable flow of the ejection openings 32 can be optimized and thus a reduction in the scattering of the jet and flow characteristics can be achieved.
  • an asymmetrical distribution of the flow-through regions 26 can be generated over the circumference, so that a uniform distribution of the fürström Schemee 26 is abandoned, the geometry and the dimensions of the fürström Schemee 26 remain the same, the widths of the guide surfaces of the guide portions 30, however, vary.
