Description

Electrode de masse améliorée pour bougie.
L'invention concerne une bougie d'allumage pour moteur à combustion interne et se rapporte plus particulièrement à l'électrode de masse constitutive de pareille bougie.
Généralement l'électrode de masse se présente sous la forme d'une tige de section rectangulaire faisant saillie d'un côté de la masse annulaire formant culot fileté de la bougie, recourbée, en forme de L, vers l'axe de la bougie pour s'approcher à un intervalle approprié au dessus de l'électrode centrale généralement concentrique audit axe.
Cette tige est le plus souvent de section droite rectangulaire. L'électrode est mise à la masse par l'intermédiaire du culot fileté qui se fixe sur le moteur.
Il est connu de varier la forme et la configuration de l'électrode de masse afin d'obtenir un effet sur l'étincelle électrique et/ou l'inflammation et/ou le mouvement ou la turbulence des gaz dans le cylindre du moteur.
On a ainsi proposé des électrodes de masse de forme et/ou de configuration complexe, p. e. annulaire autour de l'électrode centrale, ou comportant des trous, fentes ou rainures ou encore présentant plusieurs branches. Il a été également proposé une bougie comportant plusieurs électrodes en L,
<Desc/Clms Page number 2>
déformée par torsion se présentant sous forme d'hélice. Cette dernière configuration particulière permettrait d'obtenir un effet de turbulence favorable.
La présente invention propose une électrode de masse améliorée pour moteur à combustion interne caractérisée en ce qu'elle présente en section droite un profil élancé et aérodynamique par rapport au côté du cylindre opposé à la bougie.
La forme proposée serait ainsi susceptible de provoquer un flux laminaire de gaz, durant la phase de compression, au niveau et de part et d'autre de l'élément faisant office d'électrode de masse.
Selon un mode de réalisation préféré par sa simplicité de mise en oeuvre, l'électrode de masse se situe de manière classique à une distance appropriée au dessus de l'électrode centrale, mais la tige la constituant présente une section droite triangulaire, une des surfaces de l'élément prismatique constituant la tige étant perpendiculaire ou sensiblement perpendiculaire à l'axe de la bougie.
La section droite triangulaire susmentionnée peut comporter des angles plus ou moins arrondis.
<Desc/Clms Page number 3>
Selon un autre mode de réalisation la section droite de la tige ou élément équivalent faisant fonction d'électrode de masse peut avoir la forme d'une'tête d'obus'vue en section longitudinale.
La fig. l représente une configuration d'électrodes classiques comportant un corps principal tubulaire 1, un culot fileté 2, une électrode de masse 3 et 3', une électrode centrale 4 entourée de l'élément isolant 5.
La fig. 2 représente une vue correspondante avec l'électrode de masse améliorée selon un des modes de mise en oeuvre de l'invention. La fig. 3 est une vue correspondante illustrant le cas où la section présente une forme en tête d'obus.
Selon une variante de l'invention, la tige faisant fonction d'électrode peut présenter une face d'extrémité inclinée vers l'extérieur de la bougie, présentant ainsi une surface oblique par rapport à l'axe de la tige, comme illustré dans la fig. 4. Cette dernière est une vue correspondante aux fig. précédentes mais ou la tige d'électrode est vue longitudinalement, figure où la configuration normale est reprise en traits interrompus.
Il est bien entendu que la composition et la configuration de l'électrode peut varier comme déjà décrit dans l'art antérieur. L'électrode peut se présenter ainsi de manière classique en forme de tige en L, comme illustré dans les
<Desc/Clms Page number 4>
figures et exemples susmentionnées, ou selon une autre configuration connue. Une bougie peut notamment comporter plusieurs électrodes selon l'invention.
Par ailleurs, il est avantageux que les éléments supportant éventuellement ou constituant la partie non active de l'électrode de masse présente un profil également aérodynamique par rapport au côté opposé à celui ou se produit l'explosion, par exemple un profil triangulaire comme déjà mentionné. Il en est ainsi en particulier de la partie parallèle à l'axe de la bougie et de la partie courbée de la tige recourbée classique formant électrode de masse.
Il a été constaté de manière surprenante que le profil particulier de l'électrode de masse selon l'invention permet d'obtenir une performance du moteur bien supérieure, en de nombreux paramètres, à ce qui est observé avec une bougie classique (encrassement-pollution-consommation-rendement énergétique-puissance-souplesse-température de la bougie).
Les performances au démarrage du moteur et la possibilité d'utiliser un mélange plus pauvre en essence constituent des avantages particuliers.
<Desc/Clms Page number 5>
Sans vouloir être lié d'une quelconque manière par une interprétation théorique de l'effet observé, on peut envisager que la forme particulière de l'électrode selon l'invention permet au flux de qaz, durant la phase de compression, d'engendrer un phénomène de vortex avantageux entre l'électrode de masse et l'électrode centrale. Par ailleurs, durant la phase d'explosion, la bougie selon l'invention permettrait d'éviter la formation de zone d'ombre de combustion imparfaite se situant du côté de l'électrode de masse opposé à celui où se produit l'étincelle.
L'invention n'est pas limitée par les modes de mise en oeuvre susmentionnée et peut varier dans ses détails et son élaboration.

Improved ground electrode for spark plug.
The invention relates to a spark plug for an internal combustion engine and relates more particularly to the mass electrode constituting such a spark plug.
Generally the ground electrode is in the form of a rod of rectangular section projecting from one side of the annular mass forming threaded base of the spark plug, curved, in the shape of an L, towards the axis of the spark plug. approach at an appropriate interval above the central electrode generally concentric with said axis.
This rod is most often of rectangular cross section. The electrode is grounded through the threaded base that attaches to the engine.
It is known to vary the shape and configuration of the ground electrode in order to obtain an effect on the electrical spark and / or the ignition and / or the movement or the turbulence of the gases in the cylinder of the engine.
Ground electrodes of complex shape and / or configuration have thus been proposed, eg. e. annular around the central electrode, or having holes, slots or grooves or even having several branches. A candle has also been proposed comprising several L-shaped electrodes,
<Desc / Clms Page number 2>
torsionally deformed in the form of a helix. This latter particular configuration would make it possible to obtain a favorable turbulence effect.
The present invention provides an improved ground electrode for an internal combustion engine, characterized in that it has, in cross section, a slender and aerodynamic profile relative to the side of the cylinder opposite the spark plug.
The proposed shape would thus be capable of causing a laminar flow of gas, during the compression phase, at and on either side of the element acting as a ground electrode.
According to a preferred embodiment by its simplicity of implementation, the ground electrode is conventionally located at an appropriate distance above the central electrode, but the rod constituting it has a triangular cross section, one of the surfaces of the prismatic element constituting the rod being perpendicular or substantially perpendicular to the axis of the candle.
The aforementioned triangular cross section may have more or less rounded angles.
<Desc / Clms Page number 3>
According to another embodiment, the cross section of the rod or equivalent element acting as a ground electrode can have the shape of a shell head seen in longitudinal section.
Fig. l represents a configuration of conventional electrodes comprising a tubular main body 1, a threaded base 2, a ground electrode 3 and 3 ′, a central electrode 4 surrounded by the insulating element 5.
Fig. 2 shows a corresponding view with the improved ground electrode according to one of the embodiments of the invention. Fig. 3 is a corresponding view illustrating the case where the section has a shape at the top of the shell.
According to a variant of the invention, the rod acting as an electrode may have an end face inclined towards the outside of the spark plug, thus having an oblique surface relative to the axis of the rod, as illustrated in the fig. 4. The latter is a view corresponding to FIGS. previous but where the electrode rod is seen longitudinally, figure where the normal configuration is repeated in dashed lines.
It is understood that the composition and configuration of the electrode can vary as already described in the prior art. The electrode can thus be conventionally in the form of an L-shaped rod, as illustrated in the
<Desc / Clms Page number 4>
above figures and examples, or according to another known configuration. A candle may in particular have several electrodes according to the invention.
Furthermore, it is advantageous that the elements possibly supporting or constituting the non-active part of the ground electrode have a profile also aerodynamic with respect to the side opposite to that where the explosion occurs, for example a triangular profile as already mentioned. . This is particularly the case for the part parallel to the axis of the spark plug and for the curved part of the conventional curved rod forming a ground electrode.
It was surprisingly found that the particular profile of the ground electrode according to the invention makes it possible to obtain a much higher engine performance, in many parameters, than what is observed with a conventional spark plug (fouling-pollution). -consumption-energy efficiency-power-flexibility-temperature of the spark plug).
The start-up performance of the engine and the possibility of using a leaner fuel mixture are particular advantages.
<Desc / Clms Page number 5>
Without wishing to be linked in any way by a theoretical interpretation of the observed effect, it can be envisaged that the particular shape of the electrode according to the invention allows the flow of qaz, during the compression phase, to generate a advantageous vortex phenomenon between the ground electrode and the central electrode. Furthermore, during the explosion phase, the spark plug according to the invention would make it possible to avoid the formation of a shadow zone of imperfect combustion lying on the side of the ground electrode opposite to that where the spark occurs.
The invention is not limited by the above-mentioned modes of implementation and may vary in its details and its development.
