Definitions

  • the present invention relates to a spark plug, in particular for use in Internal combustion engines, with a spark plug housing and a Ground electrode carrier housing and a method for producing such Spark plug.
  • the known in the prior art spark plugs have a Ground electrode carrier housing, with which the spark plug z. B. in the cylinder head an internal combustion engine is introduced. Usually the ground electrode carrier housing Threaded on its outer surface, with which the spark plug into the cylinder head can be screwed. However, they are also spark plugs with smooth cylindrical Mass electrode carrier housings known which clamped in the cylinder head or z. B. attached to it with a bayonet lock. At the combustion chamber side End of the ground electrode carrier housing are one or more ground electrodes intended. The ground electrode carrier itself is integral with the rest Spark plug housing executed or thereto by resistance welding welded. In the known in the prior art spark plugs occur on combustion chamber end of the ground electrode carrier housing often problems with the There extremely high temperatures. It always comes back to the hot corrosion in the area the ground electrode carrier housing and thus to the negative impact or for Destruction of the spark plug.
  • the object of the invention is therefore to provide a spark plug, in which a Hot corrosion of the ground electrode carrier housing is prevented.
  • ground electrode carrier housing at least two mutually different materials having ground electrode carrier housing sections has and / or the ground electrode carrier housing other material than having the spark plug housing.
  • the invention is in the area in which the largest heat on the Ground electrode carrier housing occurs, a special material provided through which the Hot corrosion is effectively prevented.
  • the remaining structure of the spark plug can in the previously known form and using the hitherto conventional materials and thus usually be carried out inexpensively. There is both the possibility a part of the ground electrode carrier housing, as well the whole ground electrode carrier housing made of a different material than that Spark plug housing or the remaining part of the remaining To perform ground electrode carrier housing.
  • a suitable method for producing a spark plug according to the invention provides in that the ground electrode carrier housing is provided with at least two ground electrode carrier housing sections is formed, these having different materials and / or the ground electrode carrier housing made of a different material than that Spark plug housing is formed.
  • a particularly cost-effective Spark plug according to the invention prepared starting from a commercial spark plug when used on a commercial spark plug with a Ground electrode carrier housing at its in the installed position to a combustion chamber pointing end part of the ground electrode carrier housing or the entire Ground electrode carrier housing and optionally the existing ground electrode there or ground electrode assembly is removed and then a Ground electrode carrier ring on the remaining part of the ground electrode carrier housing or placed on the spark plug housing of the commercial spark plug or on it is welded, wherein the ground electrode carrier ring other material than the remaining part of the ground electrode carrier housing or the spark plug housing the commercial spark plug has.
  • the spark plug has an insulator body 1 and a this comprehensive spark plug housing 2.
  • the ground electrode carrier housing 3 which in the commercial spark plug shown in Fig. 1, the thread 9th carries, with the spark plug z. B. in the cylinder head of an internal combustion engine is screwed in.
  • a hook electrode 4 At the combustion chamber side or to the combustion chamber facing end 10th of the ground electrode carrier case 3 is a hook electrode 4 as a ground electrode arranged.
  • the center electrode 5 protrudes from the end of the hook electrode 4 Insulator body 1.
  • the connection contact 7 is provided.
  • ground electrode carrier housing 3 together with the Spark plug housing 2 is made of one and the same material, sees a first variant of the present invention, as shown in Fig. 2, at least two different Ground electrode carrier housing sections 3 'and 3 ", which from each other have different material. Both ground electrode carrier housing sections 3 ' and 3 "wear in the example shown a thread 9. It is also conceivable that only one Section 3 'or 3 "or no section carries a thread 9. The distance between the both sections 3 'and 3 "is chosen so that both sections together in a Standard thread can be screwed.
  • ground electrode carrier housing section 3 Conveniently, a higher thermal conductivity than the other ground electrode carrier housing section 3 ', whereby the occurring at the combustion chamber end 10 heat can be dissipated quickly.
  • the Combustion chamber-side ground electrode carrier housing portion 3 " as a ring on the other Ground electrode carrier housing portion 3 'mounted or welded thereto.
  • One Favorable method provides for that of the commercial spark plug according to FIG. 1 First, the area 6 of the ground electrode carrier housing 3 together with the ground electrode 4th removed and then the other material having ground electrode support ring 3 " on the remaining in the commercial spark plug ground electrode carrier housing section 3 'placed and conveniently welded thereto.
  • a second variant according to the invention consists of the entire ground electrode carrier housing 3 a different material than the spark plug housing 2.
  • the pulsed or unpulsed laser welding process a preferred Welding process.
  • Ground electrode carrier housing portion 3 carries a ground electrode 8 or one Ground electrode carrier arrangement.
  • a particularly reliable spark plug is hereby achieved when the ground electrode 8 or the ground electrode arrangement substantially inside of the spark plug pointing to a combustion chamber in the installed position Ground electrode carrier housing portion 3 "and the ground electrode carrier housing 3rd is arranged.
  • FIG. 3 The integrated ground electrode 8 is seated while inside the section 3 ", is conveniently made of the same material as the Section 3 "and can be made in one piece with this. the wall of the ground electrode carrier housing 3 or its combustion chamber side Section 3 "conveniently protrudes beyond the firing location 12 (see Fig.
  • the center electrode 5 and / or the ground electrode 8 can - as known per se - a Wear electrode plate 11, preferably made of precious metal, as an electrode.
  • a wear electrode plate 11 preferably made of precious metal, as an electrode.
  • a particularly preferred nickel-based alloy is under the material name "Inco Alloy 600" sold material number: 2.4816.
  • the Spark plug housing 2 and the optionally present section 3 'of Ground electrode carrier housing 3 can be made of the usual, usually cheaper Be made of materials.
  • Fig. 4 shows a section along the straight line AA through the combustion chamber end of the Ground electrode carrier housing 3.
  • tilt angle ⁇ of about 30 ° are preferred.
  • a further improvement of the mixture accessibility to the ignition point 12 is as in FIG. 5 exemplified by recesses 15 at the combustion chamber end of the Section 3 "and the ground electrode carrier housing 3 reached.
  • the ground electrode carrier housing 3 and his sections 3 'and 3 "each carry a thread 9 the invention is not on limited such spark plugs. Even with spark plugs, where the Ground electrode carrier housing 3 carries no thread and / or is shaped differently, can the invention can be realized. Furthermore, there are many different ones Ground electrode configurations possible. In addition to the two sections shown 3'and 3 " For example, the ground electrode carrier housing 3 may also have other sections with other ones in turn Have materials.
