Abstract

"VELA DE IGNIçãO". A presente invenção refere-se à vela de ignição tipo calafetagem de vidro, a ser fixada no motor de combustão interna. A vela de ignição, no estado da técnica, tipo calafetagem vítrea é obtida pelo encaixe do eletrodo central (101) no furo axial (103) do isolador (102) , do vidro em pó n 1 resitor e do vidro em pó n 2 , os quais se fundem, e se solidificam por resfriamento. Nesse proceso o ângulo do corne da reigião de assentamento do eletrodo central (104) é de 20 a 40° , figura 5, cuja cofiguração traz dinimuição da folga entre o flange (105) e a parede interna do eletrodo central (106), tornando-se estreita e profunda e provocando mau escoamento do vidro de calafetagem (108), que implica na variação no grau de preenchimento da região de calafetagem (109), acarretando a má condutividade ao calor, que correlaciona à pré- ignição da vela de ignição. A presente invenção com a introdução da nova configuração, alterando o ângulo do cone da região de assentamento (251), figura 2 , de 20 a 40° para 45 a 85° bem como a faixa de tolerância referente ao angulo do assentamento (521) do cone do flange (52), resolve-se o problema da fusibilidade e espalhamento uniforme do vidro, conseq³ente melhora na pré-ignição da vela de ignição no funcionamento do motor de combustão interna."Spark plug". The present invention relates to the glass caulking spark plug, to be attached to the internal combustion engine. The spark plug, in the state of the art, with glass caulking is obtained by fitting the central electrode (101) to the axial hole (103) of the insulator (102), the powder glass n 1 resistor and the glass powder n 2, which fuse, and solidify by cooling. In this process, the cornet angle of the central electrode seating region (104) is from 20 to 40 °, figure 5, whose co-configuration brings dynamization between the flange (105) and the internal wall of the central electrode (106), making it is narrow and deep and causes poor flow of the caulking glass (108), which implies a variation in the degree of filling of the caulking region (109), resulting in poor heat conductivity, which correlates to the pre-ignition of the spark plug . The present invention with the introduction of the new configuration, changing the angle of the cone of the seating region (251), figure 2, from 20 to 40 ° to 45 to 85 ° as well as the tolerance range referring to the seating angle (521) the flange cone (52) solves the problem of fusibility and uniform glass spreading, consequently improving the spark plug pre-ignition in the internal combustion engine operation.
