Definitions
- the invention relates to a fuel injection valve for internal combustion engines, as it is preferably used for the injection of high-pressure fuel directly into a combustion chamber of an internal combustion engine.
- a fuel injection valve for internal combustion engines as it is preferably used for the injection of high-pressure fuel directly into a combustion chamber of an internal combustion engine.
- use in the fuel injection of self-igniting internal combustion engines is advantageous.
- Valve needles as they are known for example from the published patent application DE 100 24 703 Al, are guided in a central guide section in the pressure chamber of the injection valve, wherein the fuel is passed by two, three or four polishes on the valve needle.
- the resulting throttling point results in a pressure drop in this area, so that the pressure in the pressure space upstream of the guide portion is higher than downstream of the guide portion, which causes a permanent closing force on the valve needles and partially compensates for the above-mentioned disadvantages.
- the throttling action depends on the viscosity of the fuel, which in turn is a function of the pressure and the temperature.
- a defined throttle point is created, which causes a pressure drop independent of the Reynolds number of the fuel, so that the throttle effect is independent of the temperature of the fuel.
- a sharp-edged gap throttle is formed between the valve needle and the wall of the pressure chamber, which causes a pressure drop independent of the Reynolds number of the fuel with suitable dimensioning.
- the Reynolds number depends, among other things, on the density and the dynamic viscosity, which in turn are essentially determined by the temperature of the fuel. Due to the independence of the Reynolds number, the damping effect of the gap choke is independent of the temperature and thus constant, which causes a constant closing force on the valve needle.
- the gap throttle is formed in a first advantageous embodiment of the subject invention by a collar having a sharp edge at its outer edge, so that between the edge of the collar and the wall of the pressure chamber, the sharp-edged gap choke is formed.
- the collar can be formed both upstream and downstream of the guide section.
- one or more bevels are formed on the collar, which also have a sharp edge, so that the independence of the Reynolds number is maintained. Due to the size of the polished sections, the flow and thus the throttle effect of the gap throttle and the closing force can be determined.
- a substantially triangular cross-section of the collar is advantageous, which is achieved by three bevels.
- the federal government can be integrally formed with the valve needle or even after completion of the valve needle glued to this, welded or shrunk.
- an inventive fuel injection valve is shown. It shows: 1 shows a longitudinal section through a fuel injector with an injection valve according to the invention,
- FIG. 2 shows the injection valve shown in FIG. 1, wherein only the part on the combustion chamber side with the essential components is shown schematically, and
- Figure 3c different embodiments of the collar and thus the gap choke.
- the fuel injector includes a fuel injection valve 1 and an injector body 100 including a control valve 30 for controlling the injection.
- the injector body 100 is connected to the fuel injection valve 1, which comprises a valve body 2 and are provided in the injection ports 8, through which the fuel is ejected.
- a valve needle 3 is arranged, which is connected to a piston rod 32, wherein the piston rod 32 with its Stirnsei- te limits a control chamber 36, which is formed in a sleeve 38.
- the control chamber 36 is connected via an outlet throttle 42, which can be opened or closed by the control valve 30, with a non-pressurized leakage oil space connectable.
- an armature 31 of the control valve is attracted by an electromagnet 33, so that the outlet throttle 42 is opened and fuel can flow from the control chamber 36 into the leakage oil space.
- the energization of the electromagnet 33 is switched off, and the armature 31 slides spring-loaded back into its initial position and closes the outlet throttle 42.
- the inlet throttle 44 the drained fuel in the pressure chamber 36 is replaced.
- the compressed fuel is made available in a high-pressure accumulator 34, the so-called rail, and fed via a high-pressure line 35 to the fuel injection valve.
- FIG. 2 the fuel injection valve of FIG. 1 is shown enlarged in longitudinal section, wherein only the part of the injection valve is shown, which faces the combustion chamber in the installed position.
- the fuel injection valve 1 comprises a pressure chamber 5 which is filled with fuel under high pressure and the
- Combustion chamber is limited to the valve seat 7, which is formed substantially conical and emanating from the multiple injection openings 8.
- the valve needle 3 is arranged longitudinally displaceable, which is formed in a piston-shaped with an axis 9.
- the valve needle 3 is guided in a guide section 10 in the pressure chamber 5, so that it is always oriented with respect to the conical valve seat 7 exactly in the middle.
- the fuel which flows into the injection openings 8, flows through the annular gap remaining between the valve needle 3 and the wall of the pressure chamber 5 and is guided in the region of the guide section 10 through a plurality of bevels 12, which provide a sufficiently large flow cross-section.
- At its valve seat facing end is at the
- Valve needle 3 a sealing surface 11 is formed, with which the valve needle 3 cooperates with the valve seat 7.
- the fuel flow is interrupted from the pressure chamber 5 to the injection openings 8 and only turned on when the valve needle 3 lifts off the valve seat 7 when planting the valve needle 3 on the valve seat 7.
- a collar 17 is formed on the valve needle 3, which extends annularly over the entire circumference of the valve needle 3.
- the collar 17 is formed sharp-edged on its outer side, wherein the thus formed edge 20 has a length L. This results in a sharp-edged gap throttle 15 between the wall of the pressure chamber 5 and the edge 20th
- the valve needle 3 At the beginning of the injection cycle, the valve needle 3 is in its closed position, that is in contact with the valve seat 7.
- the valve needle 3 is by a closing force, which is hydraulically the pressure in the control chamber 36 is generated, pressed against the valve seat 7.
- fuel In the pressure chamber 5 fuel is at high pressure, but due to the closing force no resulting force in the longitudinal direction on the valve needle 3 exerts. If an injection, the closing force is reduced, and the valve needle 3 lifts off from the valve seat 7 and outputs a fuel flow from the
- Bund 17 is formed. This resulting hydraulic force on the collar 17, which is directed in the direction of the valve seat 7, helps to close the valve needle 3 faster than would be the case with pure increase of the closing force on the valve seat 3 facing away from the valve seat.
- the amount of this closing force depends crucially on the size of the pressure drop across the gap throttle 15.
- the height of the pressure drop is in turn dependent on the cross section of the gap throttle 15 and the viscosity of the fuel, which is a function of the temperature and the pressure in the pressure chamber 5.
- the sharp-edged design of the edge 20 ensures that the pressure drop and thus the damping at the gap throttle 15 is independent of the Reynolds number and thus also independent of the viscosity and temperature of the fuel. This results in an always constant closing force on the valve needle 3 and a reproducible closing behavior independent of the operating point and independent of the temperature of the fuel.
- FIG 3a shows a plan view of the collar 17 and the gap throttle 15. Important for the function is that the gap throttle 15 is formed by a sharp edge 20.
- the size of the hydraulic diameter D Hyc decisive, which is given by the flow-through cross-section and the flow-through design length, wherein the boundary length is the sum of the inner and outer boundary length. It applies generally
- the gap throttle 15 is an annular gap with an outer diameter D a and an inner diameter D, wherein the outer diameter D a the inner diameter of the pressure chamber 5 and the inner diameter D, the diameter of the collar 17 corresponds.
- the hydraulic diameter D Hyc is then given in a good approximation by
- Fig. 3b shows an alternative embodiment of the collar 17, in which lateral slits 25 are provided, which give the collar 17 in cross-section a substantially triangular shape.
- the polished sections 25 are exaggerated here for the sake of clarity, and the length K of these polished sections 25 naturally depends on the length L of the collar 17.
- a larger number of polished sections 25 may also be provided be, for example, 4, 5 or 6 poles 25th
- S is the arc length of the bevel 25
- K is the edge length of the bevel 25
- A is the surface formed by one of the bevels 25 between the bevel 25 and the wall of the pressure chamber 5, then D Hyd results
- Fig. 3c shows a further embodiment of the collar 17, wherein here the gap throttle 15 is realized by a plurality of grooves 27 in the collar 17 and the maximum
- Length L of the collar 17 in this case depends on the dimensioning of the grooves 27.
- the remaining gap between the valve needle 3 and the wall of the pressure chamber 6 is dimensioned between the grooves 27 so that there is practically a seal and the fuel thus flows exclusively through the grooves 27.
- the boundary of the grooves 27 is sharp-edged, so that the independence of Reynolds number is maintained.
- the embodiment according to FIG. 3c is calculated as follows: If b is the width of the groove 27 and h is the depth, then
- the gap choke 15 can be arranged inside or outside the guide section 10.
- a gap choke On one side of the gap reactor 15 forming components may have a sharp edge and on the other side a smooth wall, as in the above example, the wall of the pressure chamber 5. It can also be provided that the gap choke 15 by a sharp edge on both sides is formed, for example, by the sharp-edged collar 17 in the above embodiment of FIG. 3a, a sharp-edged burr on the inner wall of the pressure chamber 5 faces. In a not too large opening stroke of the valve needle 3, the effect is maintained throughout the opening process.
- collar and ridge are aligned with each other so that the maximum damping effect acts only in the open state of the nozzle needle 3, so the collar and ridge are exactly opposite, while at the beginning of the opening stroke only a small damping acts on the gap choke, which favors the pressure build-up at the injection openings 8.
