Description


  description

Fuel injector with ignition

The present invention relates to a

Fuel injector with integrated ignition.

Reducing vehicle weight, in addition to optimizing the combustion process, plays an important role in reducing both fuel consumption and exhaust emission of automobiles. This also applies in particular to internal combustion engines themselves, which have become considerably more compact and thus also lighter in the past decades in relation to the drive power generated by them.

The reduction of the dimensions of one

Internal combustion engine also requires downsizing of all components used in and on the engine, such as fuel injectors, spark plugs, etc.

   Another

Reducing the dimensions of the components, however, set a limit, which is given by the respective function of the component. For example, the considerable forces that occur in the switching operation of a piezoelectric injector, no significant reduction in the wall thickness of the outer housing.

One approach is to merge multiple functions into one component. Thus, the functions of spark plug and injector can be integrated into a common housing.

From DE 103 37 630 Al is a fuel injection valve with a housing arranged in a piezoelectric actuator, a cylindrical valve body against the action of a

Spring moves and thus controls a fuel leak, and known with an integrated spark plug.

   The valve body is hollow and receives the high voltage electrode of the spark plug, which terminates at least approximately flush with the valve body. An ignition transformer with primary and secondary windings is arranged in the housing. The spark plug generates a spark in the region of a fuel outlet opening between a high voltage and a ground electrode.

In one embodiment, the primary and secondary windings are seated on a bobbin disposed between the piezoactuator and the valve body.

A disadvantage of this prior art is that the primary and secondary windings require additional structural length.

Petrol engines also inject more and more directly into the combustion chamber and / or use stratified charge processes.

   In these, a greater flexibility in terms of the burning time, the energy of the spark and the possible sequence of sparks in quick succession desired. A known ignition possibility, which offers these features, is the high-frequency plasma ignition, as described for example in DE 10 2004 058 925 Al.

   In this case, a resonant circuit, consisting of a coil as inductance and a capacitance excited by a high-frequency source resonant, up to the

Capacitor-performing electrodes ignites a high-frequency plasma.

In this case, the resonant circuit must be arranged directly in proximity to the electrodes of an ignition device, since even the small capacity of the mutually insulated electrodes sufficient and another distance brings an undesirably large capacity of the required longer leads with it.

It is therefore an object of the present invention to provide a fuel injection valve with integrated ignition, which allows a high-frequency plasma ignition,

   It is compact in its construction and has no much larger mass than a pure fuel injection valve.

This object is achieved by a fuel injection valve having the features of claim 1. Advantageous developments are specified in the subclaims.

It is advantageous when using a fuel injection valve according to the invention in a

Internal combustion engine only a passage through the engine block in the combustion chamber necessary. The

Internal combustion engine can thus be either built more compact or by a second implementation of another component, such as a combustion chamber pressure sensor, are used. The coil can be arranged concentrically around the piezoactuator since it does not have a core, e.g. needed from soft iron. The high hysteresis of a core would be rather annoying in the high frequency resonant circuit.

   This arrangement of the coil is therefore possible only at a high frequency plasma ignition. Also, the short lead to the first electrode is sufficient as a capacitance. As a result, a very compact design is possible, which consumes little more space than a conventional Brennstoffeinspritventil.

In a favorable embodiment, the first ignition electrode is passed through the hollow valve needle and the hollow valve body.

Thereby, e.g. a central ignition electrode can be arranged in the valve needle. The ignition energy of the plasma discharge is then available exactly at the point at which the fuel exits the fuel injection valve. Thus, the ignition of the fuel can be done with a minimum of electrical energy. It no longer has to be so high demands on the quality of the electric resonator.

   As a result, the burnup of the ignition electrode, which is extremely large due to the extremely high temperatures of the plasma discharge, is reduced to an acceptable level. In lean burn combustion engines or stratified charge combustion engines, an ignitable mixture can also be achieved more easily in the area of ignition or

   first formed by an additional injection.

In an advantageous embodiment, the valve needle and the valve body on an enclosing insulating layer, which may consist of ceramic.

Due to the electrically insulating ceramic, which is also temperature resistant and mechanically resistant, the spark from the tip of the first ignition electrode through the outlet region of the fuel through to a

Housing of the fuel injection valve and / or be directed to the mass of the internal combustion engine.

In an advantageous embodiment, a unit of the piezoelectric actuator, a Piezoaktuatorgehäuse and the

Valve needle and the valve body supported by an insulating body with respect to the fuel injection valve and isolated.

The Piezoaktuator is of a Piezoaktuatorgehäuse, usually formed by a bourdon tube,

   surround. On one side of the piezo actuator it is connected to the valve needle and on the other side to a hydraulic compensator. If this unit is isolated from the hydraulic compensator and the valve needle is also isolated, then the ignition spark can be easily fed to the first ignition electrode by a suitable electrical connection.

The coil is advantageously connected to the first ignition electrode via a wire connected to the piezo actuator housing on the side of the insulating body.

   As a result, the wire is not or only slightly burdened by the mechanical movements when operating the Brennstoffeinspritventils.

In an advantageous embodiment, the ignition voltage is coupled without contact to the first ignition electrode of the coil via a capacitive coupling element, wherein the coil is electrically connected to the first ignition electrode via this.

The high-frequency electrical energy is coupled purely capacitively into the metallic core of the valve needle.

   Thus, the possibly problematic wire connection can be omitted in the interior of the fuel injection valve.

A housing of the fuel injection valve can serve as a second ignition electrode.

The path from the tip of the first ignition electrodes to the outer edge of the housing then serves as a spark gap.

In a favorable embodiment, the

Fuel injection valve on a double-walled housing, wherein between an inner wall and an outer wall, the fuel is supplied to a sealable from the valve body sealing seat, and the coil between the inner wall and the outer wall is arranged.

The coil is then arranged in the space traversed by fuel between the inner and outer walls of the housing of the Brennstoffeinspritventils.

   This allows for a more compact design, on the other hand, the flowing fuel is forced by the spiral winding of the coil on a helical path. This improves due to the twist, the thermal coupling of the fluid to the surrounding walls, thus improving the cooling of the fuel injection valve. Alternatively, the coil may be disposed within the inner wall.

The present invention will be explained in more detail by means of embodiments with reference to the accompanying drawings.

   It shows

1 is a schematic sectional view of a first embodiment according to the invention,

Fig. 2 is a schematic sectional view of a second inventive embodiment and

Fig. 3 is a schematic sectional view of a third embodiment according to the invention.

1 shows an exemplary embodiment of a first fuel injection valve 1 according to the invention, in which a high-frequency plasma ignition system is integrated. A coil 2 is arranged inside an inner wall 3 of a housing 4 and around a tube spring 5 of a piezoactuator 7 forming the piezoelectric actuator housing. A valve needle 6 is connected to the piezoactuator 7 and has a valve body 8, which forms a sealing seat 11 with a sealing seat surface 10 arranged on a neck 9 of the housing 4.

   The valve needle 6 consists of an outer part, which consists of electrically insulating ceramic 13, and a first ignition electrode 12, which leads the ignition voltage in the region of the combustion chamber, not shown. The tube spring 5 of the piezo actuator 7 is connected via an insulating body 14 with a hydraulic compensator 15. Via a fuel supply 16, fuel is passed into a gap between the inner wall 3 of the housing 4 and an outer wall 16 of the housing 4 and finally fed to the sealing seat 11.

   The coil 2 as part of a

High-frequency resonant circuit outputs its electrical voltage via a wire 17 to a cover plate 18 of the tube spring 5 of the piezoelectric actuator 7, which does not move mechanically or at least only slightly when the piezoactuator 7 is actuated. An electrically conductive connection between the coil 2 and the first ignition electrode 12 in the valve needle 6 is thus produced via the tubular spring 5.

   The coil 2 is connected via an electrical supply line 20 with a high-frequency voltage source, not shown.

When a voltage is applied to the piezoactuator 7, the length of the piezoactuator 7 increases and the valve needle 6 lifts the valve body 18 out of the sealing seat 11 so that fuel is supplied via the fuel supply 19 and the gap between the inner wall 3 and outer wall 16 of the housing 4 the sealing seat 11 flows and is injected from there into a combustion chamber, not shown. At the same time, the hydraulic compensator 15 compensates for differences in length of the housing 4 due to the heat. Via the electrical supply line 20, a resonant circuit, which consists of the inductance of the coil 2 and the capacitance of the first ignition electrode 12 relative to the neck 9 of the housing 4, excited.

   This causes the ignition of a high-frequency

Plasma arc between the first Zündel electrode 12 and serving as the second ignition electrode neck. 9

FIG. 2 shows a further exemplary embodiment of a fuel injection valve 21 according to the invention, into which a high-frequency plasma ignition system is integrated. 1 corresponding components are designated by the same reference numerals. A coil 22 is disposed in the intermediate space between the inner wall 3 and the outer wall 16 of the housing 4 and connected via the electrical lead 20 to a high-frequency voltage source, not shown. The valve needle 6 with the valve body 8 is connected to the piezoactuator 7 and the tube spring 5. The sealing seat surface 10 on the neck 9 of the housing 4 forms with the valve body 8 the sealing seat 11.

   The valve needle 6 has an outer, electrically insulating ceramic 13 and receives the first ignition electrode 12. The Bourdon tube 5 of the piezoactuator 7 rests on the insulating body 14 on the hydraulic compensator 15. Via a fuel supply 16, fuel is introduced into a gap between the inner wall 3 of the housing 4 and the outer wall 16 of the housing

4 and finally fed to the sealing seat 11.

   The coil 22 as part of a high-frequency resonant circuit outputs its electrical voltage via a wire 23 to the cover plate 18 of the tube spring 5 of the piezo actuator 7.

The coil 22 in the space traversed by fuel between the inner wall 3 and outer wall 16 of the housing 4 of the

Fuel injection valve 21 allows a more compact design and the fuel flowing therethrough is forced by the spiral winding of coil 22 to a helical path. This improves due to the twist, the thermal coupling of the fluid to the surrounding walls 3,16 and thus improves the cooling of the fuel injection valve.

3 shows a third exemplary embodiment of a fuel injection valve 24 according to the invention with integrated high-frequency plasma ignition.

   Here, the previous figures corresponding components are designated by the same reference numerals. The arranged between the inner wall 3 and the outer wall 16 of the housing 4 coil 22 is connected to the electrical supply line 20. The valve needle 6 with the valve body 8 is connected to the piezoactuator 7 and the tube spring 5, has an outer, electrically insulating ceramic 13 and receives the first ignition electrode 12. The sealing seat surface 10 on the neck 9 of the housing 4 forms with the valve body 8, the sealing seat 11. The Bourdon tube

5 of the piezo actuator 7 abuts on the insulating body 14 on the hydraulic compensator 15.

   Instead of using a wire to make an electrically conductive connection to the first ignition electrode 12, in the present embodiment, the first ignition electrode 12 is of a capacitive

Surrounding coupling element 25 which is connected to the coil 22. When a high-frequency voltage is supplied via the electrical supply line 20, the ignition energy is transferred capacitively to the first ignition electrode 12.

   It can therefore not come to a breaking of a wire due to multiple alternating loads or vibrations.
