Definitions
- the present invention relates to a spark plug for plasma generation, used in particular for igniting internal combustion engines by electric spark between the electrodes of a candle.
- a radiofrequency spark plug of an internal combustion engine comprising two plasma generation electrodes separated by an insulator, one of the two electrodes may consist of all of the yoke and the base of the candle.
- Plasma-generation spark plugs are high-frequency, multi-spark ignition systems capable of ensuring the ignition of spark ignition engines under the best conditions, while reducing pollutant emissions, especially in lean mixtures. They are subject to fouling, especially cold.
- the present invention aims to adjust the thermal index of a multi-spark plug, so that it can quickly rise in temperature, without subsequent risk of pre-ignition.
- the chamber is disposed between the base and the insulator.
- the chamber may contain a dilation piece capable of opening or closing its inlet to hot gases.
- FIG. 1 illustrates the state of the prior art
- FIGS. 2, 3, 4A-4B and 5A-5B illustrate four embodiments of the invention.
- FIG. 1 shows a multi-spark spark plug 1 of known type, comprising two plasma generating electrodes 2, 3 separated by an insulator 4 made of a dielectric material such as a ceramic.
- the two electrodes 2, 3 constitute respectively an outer cap 3 surrounding the insulator, and a central electrode 2, housed in a central bore of the insulator 4.
- the base 3 conventionally has an external thread 3a for screwing the candle in the cylinder head of the engine.
- carbon deposits disturb the operation of the candle, creating areas of current leakage. From a certain temperature, of the order of 400 ° C., the carbonaceous deposits are destroyed by pyrolysis.
- the candle of FIG. 2 additionally has a dead volume 6 constituting an open chamber towards the outside.
- the chamber 6 extends between the base 3 and the insulator 4.
- the chamber may advantageously have a first tubular sector 6a connected to a second circular sector 6b open on the outside.
- the walls of the chamber 6 may be metallized.
- the layer, or metal sleeve 7, applied to the insulator, is then in direct contact with the hot gases, and particularly oxidants in lean mixture ("lean - AT -
- This metal layer 7 may for example consist of a sleeve brazed to the ceramic, which will ensure the resistance thereof to the oxidizing gases.
- the thickness of the sleeve may be a compromise between its resistance to thermochemical erosion, its thermal resistance and its cost of production. Indeed, if the sleeve is too thick, its thermal resistance will be too low, and the ceramic will not heat up enough to destroy the deposits by pyrolysis.
- the material of the sleeve will also be chosen according to its conductivity and its coefficient of expansion, which must be compatible with that of the ceramic and the mechanical properties of the latter.
- the metal layer may itself be protected by an inert deposition, a thin ceramic layer, or other metal deposit particularly resistant to oxidation, such as nickel.
- FIG. 3 illustrates a second embodiment of the invention, according to which the chamber 6 is a simple tubular opening formed in the mass of the base 3.
- the chamber no longer extends between the base and the insulator , as before, but constitutes a cut in the mass of the base.
- the application of a metal layer 7 is imperative to avoid the formation of a plasma.
- the metallization will be applied simply on the bonding interface between the ceramic 4 and the base 3, independently of the chamber 6.
- FIGS. AA to 5B illustrate additional provisions making it possible to automatically adapt the behavior of the chamber to the temperature conditions of the candle, so as to further improve the "non-linear" setting of the thermal index of the candle, in particular to that it behaves like a very hot candle when the engine is still cold, and like a warm candle, when the engine is hot, especially under heavy load.
- the chamber 6 may contain a dilation piece 8, 9 capable of opening or closing its inlet to hot gases.
- the expansion chamber is contracted, and opens the passage to hot gases that provide a thermal flow accelerating the operation of the candle.
- the room is expanded and closes the hot gas passage.
- the candle reaches its thermal equilibrium at a lower temperature than if the chamber had remained open.
- the expansion member 8 is a corrugated sleeve, one end is fixed and the other end carries a cylindrical flap 8a closing the inlet of the chamber 6 when the sleeve is expanded.
- the expansion part 9 is a double wall sleeve containing a relatively low temperature fusible metal 9a: the expansion of the liquid metal 9a causes the sleeve 9 to swell, thus blocking the passage of the hot gases.
