Title (EN) SPARK PLUG AND METHODS OF CONSTRUCTION THEREOF
(FR) BOUGIE D'ALLUMAGE ET PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)A spark plug and method of construction is provided, wherein the spark plug has a generally annular ceramic insulator and a metal shell surrounding at least a portion of the insulator. A ground electrode is operatively attached to the shell, wherein the ground electrode has a ground electrode sparking surface. The spark plug further includes a center electrode having an elongate body with a center electrode sparking surface. The sparking surface of the center electrode and the ground electrode sparking surface provide a spark gap. A brazed joint bonds at least one of the insulator to the shell or the center electrode to the insulator.
(FR)L'invention concerne une bougie d'allumage et un procédé de fabrication. Ladite bougie comporte un élément d'isolation généralement annulaire en céramique et coque métallique entourant au moins en partie cet élément. Une électrode de masse est reliée opérationnel à la coque, et comporte une surface d'allumage propre. Ladite bougie comporte en outre une électrode centrale à corps allongé qui présente une surface d'allumage propre. Les deux surfaces d'allumage en question permettent d'établir un intervalle d'allumage. Un joint brasé assure la liaison soit entre l'élément isolant et la coque soit entre cet isolant et l'électrode centrale.
