Definitions
- the invention relates to a fuel injection device for Internal combustion engines, especially two-stroke large diesel engines, according to the preamble of claim 1.
- a fuel injection device of this type is known from EP 0 606 371 B1 known.
- the central exhaust valve provided for the cylinder head must be Fuel injection devices generally in the area of Periphery of the combustion chamber can be arranged.
- the nozzle bores the nozzle head are arranged so that one after main injection direction on one side of the nozzle head results.
- the nozzle holes are in relation to the axis of the Blind hole not arranged radially, but have one for Main injection direction towards the course. this leads to different lengths of the nozzle bores with each other and to different bore lengths over the circumference of individual Holes.
- the measures according to the invention ensure that at all Nozzle holes almost the same conditions for one unimpeded entry of the fuel can be reached. Let it be yourself with the help of the entrance chambers in an advantageous manner achieve the same bore lengths for all nozzle bores. Likewise, the scope of the individual Nozzle bores reach unchanging jacket lengths.
- the Measures according to the invention therefore lead in an advantageous manner Way, overall at equal aspect ratios, resulting in a Uniformization of wall friction and flow velocities and thus a stable overall Injection jet leads.
- the Entrance chambers as hemispherical in cross section Recesses of the nozzle head can be formed.
- the hemispherical recesses allow advantageously Way of creating exactly the same wetting angle over the whole Scope of a nozzle bore. They are useful hemispherical recesses arranged so that you Center point on the axis of the assigned nozzle bore lies, so that this with respect to the center of the assigned Entrance chamber is centered.
- the formation of the entrance chambers as hemispherical Recesses of the nozzle head also ensure that a simple way to match each nozzle bore Entrance chamber can be assigned without the nozzle head would be weakened too much.
- Another advantage is the fact that the hemispherical Recesses can be arranged so that in the area between two neighboring ones Recesses each result in a standing web, which as Guide bar for the slide element can act, whereby it is protected against wear.
- Another advantageous embodiment of the parent Measures can be that the entrance chambers as annular segment-shaped recesses of the nozzle head are. This is a particularly inexpensive manufacture possible. The design also enables it to be achieved comparatively well adapted to a value of 90 ° contact angle in the transition area between a nozzle bore and the each assigned entrance chamber.
- Another advantage is that one of the others Nozzle holes flanked by the middle group of Nozzle holes assigned a common entrance chamber can be without the nozzle head being weakened too much.
- the injection valve 1 on which FIG. 1 is based consists of a box-shaped, tapering towards the front Jacket housing 2, which is provided with a blind hole 3
- Nozzle head 4 carries. This is supported by a rear one Flange on a front collar of the casing 2.
- the Nozzle head 4 closes with its rear end to one in Shell housing 2 received guide sleeve 5, which with one to the blind bore 3 of the nozzle head 4 coaxial Through hole 6 is provided.
- This has one step-shaped constriction, which is designed as a valve seat 7, with which cooperates a valve body 8, the one in the Guide sleeve 5 arranged shaft 9 protrudes.
- the diameter of the valve body 8 is smaller than the diameter of the shaft 9, so that a surrounding the valve body 8 for Bore 6 belonging annulus 10 results.
- the shaft 9 is connected to a central fuel line connected bore 11 which can be filled with fuel provided with the annular space 10 via tap holes 12 connected is.
- the valve body 8 is by the action of a not shown here, with the shaft 9 cooperating return spring to the sealing seat 7 pressed. With a corresponding pressure increase in the Annulus 10 pending fuel, the valve body 8 from assigned sealing seat 7 is lifted, which is a Connection of the area to which fuel can be applied with the Blind hole 3 of the nozzle head 4 results.
- the nozzle head 4 is in its lower area with several, approximately arranged at the same height next to each other, transverse to the axis of the Blind bore 3 extending nozzle holes 13 provided about which the fuel into an associated combustion chamber is injectable.
- annular slide element 15 is provided, the lower edge forms a control edge passing over the nozzle bores 13 which is arranged so that the nozzle bores 13 are open when the valve body 8 is lifted off the associated valve seat 7 and that the nozzle bores 13 are closed when the Valve body 8 rests on valve seat 7. This position is the figure 1 underlying.
- each several approximately in the direction of the axis of the blind bore 3 arranged at the same height, laterally offset from each other Nozzle bores 13 are provided, as in FIGS. 2 and 3 can be clearly seen.
- the nozzle bores 13 can Axially normal or, as in Figure 4, slightly outward be inclined. Because of the nozzle bores 13 in common generated injection jet should not diverge too much, are the No nozzle bores 13 with respect to the axis of the blind bore 3 arranged radially, but opposite to a radial Main injection direction turned so that there is a smaller Diverging or scattering angle results.
- the nozzle bores 13 up to without changing the cross section would go to blind hole 3, would be very strong divergent inflow ratios to the individual Nozzle bores 13 and also within individual ones Nozzle holes 13.
- the two outer ones Nozzle bores 13 of the four provided next to each other arranged nozzle holes 13 comprising row of holes would be significantly longer than the inner nozzle bores 13, whereby in the area of these outer nozzle bores 13 whose scope would also result in different lengths. This Conditions would lead to bad combustion and thus to high fuel consumption and too high Lead to pollutant emissions etc.
- the above are used to form mentioned entrance chambers starting from the blind bore 3, hemispherical recesses 17 of the nozzle head 4 intended.
- the hemispherical recesses 17 can simply by electrolytic material removal with the help of a according to the EDM (electrical discharge machining) process working device are manufactured.
- the nozzle bores 13 themselves are simply drilled using a laser beam.
- Recesses 17 are arranged so that their center each lies on the axis of the associated nozzle bore 13. On this results in centering of the nozzle bores 13 with respect to the assigned entrance chamber. This centering ensures that in the area of the transition between Entry chamber and nozzle bore 13 all over Hole circumference results in a roughly constant contact angle, as indicated in Figure 2 at 18.
- each assigned hemispherical recesses 17 are so dimensioned that between two adjacent hemispherical recesses 17 a web 19 remains, which acts as a guide bar for the annular slide element 15 can act so that this also in the area of Entrance chambers are reliably supported, which is advantageous affects the achievement of a long lifespan.
- Nozzle bores 13 are assigned to an input chamber 16. at that on which FIG. 2 is based, preferred Embodiment are all nozzle holes 13 through hemispherical recesses 17 formed entrance chambers assigned what particularly good combustion conditions and thus expect particularly low fuel consumption leaves.
- FIG. 3 is based the nozzle bores 13 as ring segment-shaped recesses 20 of the nozzle head 4 assigned input chambers.
- the radii of the ring segment-shaped recesses 20 are included so to the respectively assigned nozzle bore 13 or Nozzle holes 13 adapted that in the transition area between the input chamber and nozzle bore 13 as possible edge angle approximated to 90 ° results, as in FIG. 3 at 21 is indicated.
- each nozzle bore 13 it would be conceivable for each nozzle bore 13 to have its own one To assign ring segment 20 formed entrance chamber.
- the two middle nozzle bores 13 a common, formed by a ring segment 20 Assigned to the entrance chamber.
- This ring segment 20 corresponds a section of the axis of the blind hole 3 of the Nozzle head 4 coaxial ring groove and is characterized by the neighboring, assigned to the two outer nozzle bores 13 Ring segments 20, which have a smaller radius, limited.
- outer ring segments 20 are arranged so that you Center point on the axis of the assigned nozzle bore 13 is located, so that this with respect to the associated Entrance chamber is centered, resulting in an equalization of the Inflow conditions over the entire circumference of the bore contributes.
- the center of the two middle nozzle bores 13th assigned ring segment 20 is in the area between the two axes of the two associated nozzle bores 13.
- FIGS. 3 and 4 are based on an example larger diameter than the nozzle bores 13 Cutout 22 provided. This leads to a step-like Cross-sectional expansion with one to the respective bore axis normal ring surface surrounding the end of the bore 23.
- the Cutout 22 ensures that the nozzle bore 13th emerging beam experiences no interference.
