Abstract

The annular earth electrode is in the form of the conventional earthing electrode but with the outer end in the form of a ring with a hollow centre. The hollow centre is placed immediately above the centre electrode of the spark plug. The spark spreads sideways as in a conventional spark plug, but also spreads into the hollow centre of the earth electrode, increasing the area of the spark in contact with the air/fuel mixture.

Description

DESCRIPTION
Electrode de masse annulaire peur bougie d'allumage.DESCRIPTION
Annular ground electrode for spark plug.

@a présente invention concerne un dispositif permettant d'obtenir une électrode de masse en forme d'anneau qui coiffe l'électrode centrale d'une beugie d'allumage. @a present invention relates to a device for obtaining a ground electrode in the form of a ring which covers the central electrode of a spark plug.

L'étincelle d'une beugie classique est masquée par son électrode de mase traditionnelle, véritable bouclier qui porte préjudice à la propagation du front de flamme, notamment pour les moteurs à explosion. The spark of a classic candle is masked by its traditional mase electrode, a real shield which damages the propagation of the flame front, especially for internal combustion engines.

Selon l'invention, le dispositif permet de remédier à cet inconvénient
Avec son électrode de masse annulaire et son puits ouvert sur l'électrode centrale, l'étincelle est mise en évidence, au bénéficie de la combustion, du rendement et de l'économie d'énergie. De par sa constitutien cylindrique, l'électrode de nasse annulaire permet t l'étincelle de ne pas se produire au même encrait, en se déplaçant autour du cercle, retardant l'usure des électrode et favorisant la durée de vie de la bougie.According to the invention, the device makes it possible to remedy this drawback
With its annular mass electrode and its well open on the central electrode, the spark is highlighted, to the benefit of combustion, efficiency and energy saving. Due to its cylindrical structure, the annular trap electrode allows the spark not to occur at the same ink, by moving around the circle, delaying the wear of the electrodes and promoting the life of the spark plug.

Le dispositif, selon l'invention, est particulièrement destiné aux bougies d'allumage des noteurs à explosion.  The device, according to the invention, is particularly intended for spark plugs of explosion rating agents.
