Definitions
- the invention relates to a plasma generating plug of the type used for spark ignition engines.
- FIG. 3 shows such a candle 1 comprising a base 2 of tubular shape, containing a dielectric insulator 3.
- the base 2 forms an electrode, generally connected to the ground.
- the isolator 3 comprises a central bore 30 in which is housed a central electrode 4.
- the isolator 3 separates the electrodes 2, 4 in the zone where the distance between them is the lowest; The sparks formed between the electrodes are thus guided on the surface of the insulator.
- the parts of the candle are assembled by interlocking. There is then a gap between them. In particular, there is a gap Jl between the base 2 and the insulator 3, and a gap J2 between the insulator 3 and the central electrode 4. It is found that sparks propagate in these interstices when the central electrode of the candle is powered with a high voltage radio frequency. This leads to an expenditure of energy which is not used to the useful function of the spark which is to ignite the gaseous mixture near the candle.
- the insulator to be at a relatively high temperature, for example 400 ° C.
- the carbon deposits disturb the proper functioning of the candle, creating current leakage lines. At this temperature, the carbonaceous deposits are destroyed by pyrolysis. By filling in gaps Jl and J2, the thermal resistances between the parts are reduced. The parts are therefore at more homogeneous temperatures, generally lower than that desired for the insulator.
- the candle is usually screwed by one of the electrodes in the cylinder head of the engine, itself cooled by the circulation of a coolant.
- the object of the invention is a radiofrequency plasma generation candle having at least two elements, one of the elements being a first metal electrode and the other being an insulator, one of the elements having a housing in which the other is mounted with a gap.
- the surface of the insulator facing the first electrode is metallized.
- the insulator and the electrode are housed one inside the other, contact inevitably occurs between the metal coating of the insulator and the electrode.
- the surfaces facing each other and separated by the gap are therefore at the same potential, which has the effect of preventing the spread of sparks in this area.
- the sparks thus occur entirely outside the insulator and serve entirely for igniting the surrounding gases.
- the partial metallization of the insulator makes it possible to reduce the point accumulation of electric charges, and thus to improve the resistance of the insulator. the insulator to breakdown phenomena. The insulator thus supports higher voltages.
- the candle according to the invention also retains the gap between the insulator and the electrode.
- the differential expansions do not induce mechanical stresses and the choice of materials for the electrode and the insulator is not constrained by the desire to avoid differential expansions.
- the interstice creates a thermal resistance between the insulator and the electrode, which avoids homogenizing their temperature. Even if the electrode is cooled by the fact that it is fixed to a solid element of the motor, the insulator is not cooled so intensely and can have a higher temperature, suitable for the pyrolysis of any carbonaceous deposits.
- the first electrode is cylindrical and housed in a bore of the insulator.
- the metallized portion is then the bore of the insulator.
- the spark plug has a second electrode surrounding the insulator, the surface of the insulator facing the second electrode being metallized.
- the insulator is, for example, ceramic.
- FIG. 1 is a sectional view of a plasma generation candle according to one invention
- FIG. 2 is a view of detail II of FIG.
- Figure 3 is a view similar to Figure 1 of a candle according to the prior art, and described above.
- a radiofrequency plasma generation candle 10 according to the invention is shown in FIGS. 1 and 2. It comprises, like the candle according to the prior art, a base 12 of tubular shape, containing a dielectric insulator 13.
- the base 12 forms an electrode, generally connected to the ground.
- the isolator 13 comprises a central bore 130 in which is housed a central electrode 14.
- the insulator is ceramic, for example silicon nitride, but it can be in vitro ceramic, or amorphous material such as quartz.
- the insulator 13 has surfaces coated with a metallization.
- a first zone A extends on a cylindrical part of the insulator facing the base 12.
- a second zone B extends into the bore 130 of the insulator 13. facing the central electrode 14.
- a gap 15 is provided between the base 12 and 13.
- a gap 16 is provided between the central electrode 14 and the insulator 13.
- the interstices have a width of the order of a few hundredths to a few tenths of a millimeter.
- the insulator 13 has a first metal layer 132 which extends over the entire first zone A.
- the insulator 13 comprises a second metal layer 133 which extends over the entire second zone B.
- the metal layers 132, 133 are obtained by any conventional method of ceramic metallization.
- metal salts are deposited on the zones A, B of the insulator 13, in the form of liquid solutions.
- the application is made for example by brush, roller or projection.
- the insulator 13 is passed through a reducing atmosphere furnace, for example with an atmosphere containing hydrogen. In this way, the metal salts are reduced and a thin layer of metal is formed on the zones A, B.
- metal layers 132, 133 are typically of the order of 5 to 50 ⁇ m.
