Definitions

  • the present invention relates to a mounting sleeve for a spark plug in the Wall of the mounting sleeve arranged, substantially in Spark plug longitudinal coolant channels.
  • the function of such a mounting sleeve is to make a spark plug safe and secure to anchor in the cylinder head.
  • the fastening sleeve in the front area an extension pointing in the direction of the through-channel of the fastening sleeve in which a thread is incorporated.
  • the spark plug is in this thread screwed in.
  • the mounting sleeve also dissipate the heat generated during ignition.
  • you have the wall of the prior art (Fig. 1) Fastening sleeve usually provided with straight coolant channels. These straight coolant channels could easily be made by drilling become. Practical experience shows, however, that the construction of the Fastening sleeve ensures good anchoring, but in the increasingly required cooling due to the ongoing Performance increase of the engines hardly reached the required values. A however, inadequate cooling leads to faster spark plug wear.
  • the object of the present invention is now a fastening sleeve offer a longer due to a further improved heat dissipation Ensures the life of the spark plugs.
  • fastening sleeve from one metallic material whose thermal conductivity is over 60 W / m ° C, is preferably above 80 W / m ° C.
  • Particularly suitable materials are brass or nickel as well as those formed with them Alloys.
  • the prechamber is made by one Ring channel is surrounded, in which the coolant channels open.
  • a preferred embodiment provides that the coolant channels in the front, preferably a thread for screwing in the area of the spark plug Mounting sleeve are approximated to the spark plug.
  • the coolant channels move thus closer to the place of greatest heat and can heat discharge more efficiently.
  • a variant provides that the coolant channels in the front area of the Have extensions pointing towards the spark plug. Practical Experiments have shown that despite the weakening of the front area Fastening sleeve through the extensions still have sufficient stability is given to securely anchor the spark plug.
  • the weakening of the front area can be avoided in that the Course of the coolant channels in the front area of the mounting sleeve on the contour the spark plug is adjusted.
  • the adaptation to the contour of the spark plug increased however, the manufacturing costs for the manufacture of the coolant channels.
  • Optimal cooling results are achieved if the remaining wall thickness in the front Part of the mounting sleeve between the spark plug and coolant channels is less than 5 mm, preferably about 2 to 3 mm.
  • the fastening sleeve 2 serves to hold a spark plug 1 in the Anchor cylinder head 9.
  • the mounting sleeve 2 is between one and Exhaust valve 8 arranged.
  • the fastening sleeve 2 is reinforced in its front area 2a. In this area 2a, a thread 5 is provided, into which the spark plug 1 is screwed.
  • cooling channels 3 run through the wall of the mounting sleeve.
  • these cooling channels 3 are straight cylindrical bores educated. They lead from a manifold 10 straight to the ring channel 7, which Pre-chamber 6 arranged in front of the spark plug 1 on the fastening sleeve 2.
  • the coolant thus comes closer to the largest Heat development in the front area of the spark plug 1.
  • the fastening sleeve 2 can be made of brass, of a brass alloy, of nickel, made of a nickel alloy or another metallic material be produced if the thermal conductivity is above 60 W / m ° C., preferably above 80 W / m ° C. At the same time it must have sufficient strength for a safe Anchoring of the spark plug 1 may be given.
  • the thermal conductivity of brass and Nickel is about three times that of the high-alloy steel used previously, whereas the strength values are only slightly worse. For brass and Nickel also speaks the better machinability.
  • the antechamber 6 which is soldered to the fastening sleeve 2 (FIG. 2) or screwed on (Fig. 5), consists of a nickel-chromium alloy with about 30% Chromium content. This alloy makes the prechamber 6 particularly heat-resistant.
  • FIG. 5 differs from FIG. 2 in addition to the different connection of Prechamber and mounting sleeve in that the extensions 4 in the form of Additional holes are made. These additional holes are manufacturing technology particularly easy to carry out. Again, the remaining wall thickness is strong reduced.
  • the extensions 4 arrive at a distance of about 2 to 3 mm the spark plug 1.
