Definitions

  • the invention is based on a spark plug with the features specified in the preamble of claim 1.
  • a spark plug is from the EP 0 954 074 B1 known.
  • Advanced gasoline engines require more space in the cylinder head for intake valves and exhaust valves, and this is one reason why spark plugs with smaller diameters than before are required today.
  • Lighter spark plugs need a slimmer insulator. This in turn requires higher demands on the mechanical strength and electrical insulation, namely the dielectric strength, of the existing in the spark plug insulator, which usually consists of an alumina ceramic.
  • the JP-A 63-190753 discloses an alumina ceramic insulator made by mixing 95% by weight of alumina powder having an average particle size of 0.1 ⁇ m to 0.5 ⁇ m with yttria, magnesia and lanthana, liquid phase pressing and sintering.
  • the yttria, magnesium oxide and lanthanum oxide together make up 5% by weight of the mixture and serve as a sintering aid by leading to a liquid phase during sintering, the melting point of which is far below the melting point of the aluminum oxide.
  • the liquid phase spreads at the boundaries of the alumina particles and is said to inhibit their growth in the sintering process so that the sintered insulator still has a very finely divided structure.
  • the preserved by the sintering aids fine structure leads to the disclosure of JP-A 63-190753 extending the aluminum oxide particles extending along the boundaries of the sintering aids enriched paths over which electrical charges would move when voltage breakdown, and thus leads to an increase in the dielectric strength of the insulator.
  • an adverse effect on the electrical breakdown strength the fine pores, which are particularly numerous in the finely structured sintered insulator and the number increases with increasing content of alumina in the insulator, because at the same time the proportion of sintering aids, by the formation of a liquid phase the pores could close, decreasing.
  • This insulator is prepared by mixing alumina powder having an average particle size of not more than 1 .mu.m with 0.3 to 5 wt .-% of a sintering aid, pressed and sintered at a temperature between 1450 ° C and 1700 ° C in the liquid phase.
  • the sintering aid is selected so as not to interfere with the growth of the alumina powder particles during sintering. The sintering process takes place until at least half of the aluminum oxide has grown to particles with a size of 20 microns or more.
  • the sintering aid forms a liquid phase during sintering, which is to favor a small pore volume.
  • the present invention aims to further improve the dielectric strength of the insulator in spark plugs both at room temperature and, in particular, at the high temperatures which occur when the gasoline engine is in operation.
  • the spark plug according to the invention has an insulator containing 0.01 wt .-% to 1 wt .-% magnesium oxide, at most 0.3 wt .-% natural and / or caused by the manufacturing process impurities and the balance alumina and is formed by solid phase sintering , so that it is largely free of glass phases.
  • the insulator of the new spark plug contains 0.03 wt% to 0.15 wt%.
  • Magnesium oxide Even small additions of magnesium oxide reduce the crystal growth of the alumina during solid-phase sintering. From a content of 0.03 wt .-%, this effect becomes technically significant. At a content of more than 0.15% by weight of magnesium oxide, this effect is no longer significantly increased.
  • the insulator contains only natural and / or process-related impurities.
  • the invention dispenses with the addition of any sintering aids such as sodium oxide, yttrium oxide, lanthanum oxide, silica, barium oxide, boron oxide and the like, which at temperatures at which alumina can be sintered in solid phase, would form a liquid phase, from which after solidification Glass phase would.
  • Any minimal glass phases which may be detectable in an insulator according to the invention, can therefore only from the natural and / or process-related impurities present in the alumina come. In this sense, the statement in claim 1 is understood that the insulator should be largely free of glass phases.
  • the insulator of the spark plug according to the invention preferably contains more than 99.7% by weight of aluminum oxide. In this case, glass phases caused by the remaining impurities can no longer appreciably affect the electrical breakdown strength of the insulator.
  • a density of at least 3.85 g cm -3 is preferred.
  • a high density can be achieved if one starts from a very fine alumina powder, which preferably has an average particle size of less than 1 micron, if the insulator blanks sufficiently compacted before sintering, in particular by isostatic pressing, and if the sintering temperature and the sintering time is coordinated so that an insulator is obtained in which 90 wt .-% of the alumina having particle sizes of less than 5 microns, even better, with particle sizes of less than 3 microns.
  • the temperature for the solid phase sintering is a temperature in the range of 1,600 ° C to 1,700 ° C, well below the melting temperature of alumina, which is above 2,000 °.
  • FIG. 1 shows in a partially sectioned side view of the typical structure of a spark plug according to the invention, which has a center electrode 1 and in its extension a firing pin 2, which are at a distance behind each other in an insulator 4 according to the invention, namely in a longitudinal channel, in which they by a electrically conductive glass phase 3 are interconnected.
  • the insulator 4 is inserted in a metallic body 5, in which it is fixed by crimping and electric diving.
  • a ground electrode 6 is mounted, which is bent towards the center electrode 1 and this opposite to form a discharge gap with a defined distance.
  • the insulator consists z. B. from 99.8 wt .-% alumina, about 0.1 wt .-% magnesium oxide and the balance of natural and / or process-related impurities. It is formed by solid-phase sintering and contains no glass-containing secondary phase that can be detected by X-ray analysis.
  • the insulator according to the invention can be mounted in a known manner in the body 5 of the spark plug, so that existing manufacturing facilities and methods for mounting the insulator 4 as well as the center electrode 1 and the firing pin 2 can be used.
  • the required ceramic-metal compound is effected by means of an electrically conductive composite glass.
  • the electrically conductive glass mass 3 ensures the electrical connection between the center electrode 1 and the firing pin 2 and moreover has the task of introducing the center electrode 1 into the isolator 4 in a pressure-tight manner.
