Definitions
- the invention is based on a fuel injector with an integrated spark plug according to the preamble of claim 1 and claim 6.
- DE-OS 196 38 025 a fuel injection valve with an integrated spark plug for the direct injection of fuel into the combustion chamber of an internal combustion engine and for igniting the fuel injected into the combustion chamber.
- an externally opening valve closing body interacts with a valve body to form a sealing seat.
- the valve closing body is formed in one piece with a valve needle which extends in the interior of the sleeve-shaped valve body.
- the valve needle is guided on the one hand by the valve closing body and on the other hand by a guide ring provided on the inlet side.
- An electrical high voltage can be applied to the valve body via a high-voltage cable and has an ignition electrode on its spray-side end.
- the valve body is radially surrounded by a ceramic insulation body, which in turn is surrounded by a metallic housing body which has a further ignition electrode.
- the valve needle and the valve closing body which is formed in one piece with the valve needle, is actuated in the opening direction by an armature which interacts with a magnetic coil.
- the armature acts via a plunger on an insulating intermediate piece which lies against the guide ring of the valve needle.
- valve needle has no high-voltage insulating element.
- the isolation is therefore carried out by the intermediate piece described, which is only non-positively, but not positively connected to the valve needle.
- This The design is therefore only suitable for fuel injectors that open from the outside. Since only an opening force, but not a closing force, can be transmitted via the valve needle to the valve closing body via the intermediate piece, a valve closing spring must be integrated in the valve body to generate the closing force. This leads to a relatively complex structural design and thus to relatively high manufacturing and assembly costs.
- the fuel injector according to the invention with an integrated spark plug with the characterizing features of claim 1 has the advantage that an insulating section which is insulating in the axial direction and which separates two metallic guide sections from one another is integrated in the valve needle.
- the guidance of the magnetic needle takes place through the metallic guide sections which, for. B. can be made of hardened steel, and are therefore precisely manufactured and whose surfaces have a low coefficient of friction.
- a first guide section is arranged on the spray side and can be formed in one piece with the valve closing body.
- the second metallic guide section is arranged on the inlet side with respect to the insulation section arranged between the guide sections and is guided in the insulation body.
- the guide sections are not only positively but also positively connected to the insulation section, so that a force transmission via the valve needle is possible both in the opening direction and in the closing direction.
- the integration of a return spring within the valve body is therefore not necessary.
- the result is a structurally simple configuration that can be produced with little manufacturing and assembly effort.
- the insulation body can be manufactured as a molded ceramic part with little manufacturing effort. Since the insulation section only takes over the insulation, but not the guidance of the valve needle, the production accuracy and the abrasion resistance of the insulation section are not particularly demanding.
- the fuel injector according to the invention with an integrated spark plug with the characterizing features of claim 6 has the advantage that the valve needle formed with the valve closing body as a one-piece ceramic component can be made particularly short, since no metallic components are used and the entire length of the valve needle serves as an insulation path. The shortening of the valve needle results in a significant weight reduction, which in turn leads to relatively short switching times.
- connection between the guide sections and the insulation section is preferably made via connecting pins which engage in corresponding recesses.
- the connection can be made by friction flow, gluing or partly by shrinking.
- valve closing body is preferably spherical or partially spherical in order to avoid material splintering in the seating area.
- the insulation body preferably has a lateral recess, through which a high-voltage cable is led to the valve body and is connected to it in an electrically conductive manner. It is advantageous to shed the recess by an electrically insulating casting compound, since this provides a particularly good protection of the z. B. formed by welding or soldering connection of the high-voltage cable to the valve body. An electrical erosion resistor or a high-voltage-resistant insulation film for improved insulation of the soldering or welding point can also be cast into the casting compound in a particularly advantageous manner. drawing

- the valve needle 9 and the valve closing body 10 are formed in one piece.
- the valve closing body 10 When the valve closing body 10 is lifted off the valve seat surface of the valve body 7, the valve closing body 10 releases an outlet opening 12 formed in the valve body 7, so that a conical spray jet indicated by the line 13 is sprayed off.
- at least one swirl groove 14a is provided in the swirl insert 14 in the exemplary embodiment shown.

- the valve needle 9 is guided a second time in the insulation body 6 by means of the second guide section 9b.
- the outer surface 19 of the second guide section 9b interacts with a bore 20 in the insulation body 6.
- the guide sections 9a and 9b serving as guides are designed as metallic components and can be manufactured with the manufacturing accuracy required for the guide. Due to the low surface roughness of the metallic components, there is only a low coefficient of friction on the guides.
- the insulation section 9c can be produced as a molded ceramic part. Since the insulation section 9c does not serve to guide the valve needle 9, only small demands are made on the dimensional accuracy and the surface roughness. A revision of the spray ceramic part is therefore not necessary.
- the guide sections 9a and 9b are connected to the insulation section 9c not only in a force-locking manner but also in a form-fitting manner.
- the guide sections 9a and 9b each have a pin 21 or 22, which is respectively inserted into a recess in the insulation section 9c designed as a bore 23.
- the connection between the pins 21 and 22 of the guide sections 9a and 9b is preferably by a frictional connection O
- the guide section 9b has a recess into which a pin of the insulation section 9c can be inserted.
- the metallic guide section 9b can then be heated before shrinking on, and the pin of the insulation section 9c can be inserted into the recess when the guide section is heated.
- the guide section 9b cools, it contracts, so that there is a firm connection with the insulation section 9c.
- the insulation section 9c is preferably sleeve-shaped.
- the material saved compared to a solid body results in a weight saving, which leads to shorter switching times of the fuel injector 1.
- valve needle 9 and the valve closing body 10 are formed as a one-piece, ceramic component.
- the valve needle 9 can be made shorter compared to the embodiment shown in the drawing, since the valve needle 9 has insulation properties over its entire length. This results in a weight saving of the valve needle 9, which leads to shorter switching times.
- the valve needle 9 and the valve closing body 10 are formed as a one-piece ceramic component, it is advantageous if the valve closing body 10 is spherical or partially spherical, so that material splintering on the sealing seat is avoided.
- Silicon nitride or zirconium oxide is particularly suitable for achieving a particularly low weight for the insulation section 9 c or for the valve needle 9 with the valve closing body 10, which is formed as a one-piece ceramic component in accordance with the alternative exemplary embodiment.
- the second guide section 9b is connected to an armature 24, which cooperates with a magnet coil 25 for the electromagnetic actuation of the valve closing body 10.

- a locking sleeve 38 serves to secure the setting of the adjustment sleeve 36.
- the fuel continues to flow through a longitudinal bore 39 in the second guide section 9b of the valve needle 9 and enters an cavity 40 of the insulation body 6 at an axial recess 40. From there, the fuel flows into a longitudinal bore 42 of the valve body 7, in which the valve needle 9 also extends, and finally reaches the swirl groove 14a already described in the swirl insert 14.
- the first ignition electrodes 15 connected to the housing body 2 have ground potential, while the second ignition electrodes 16 connected to the valve body 7 can be subjected to a high voltage potential for generating ignition sparks.
