Abstract
"VELA DE IGNIçãO". A presente invenção refere-se à vela de ignição utilizada, por exemplo, no motor de combustão interna atinente aos veículos automotivos. A vela de ignição precipuamente é constituída do castelo metálico (1), que atribui como polo de contacto, abriga isolador (2) cerâmico à base de alumina e por sua vez, dentro do qual resguarda-se o eletrodo central (3). Aplica-se a tensão entre o eletrodo central (3) e eletrodo lateral (4), que é a extensão do castelo (1), para importar centelhas na folga (g) existente entre a extremidade do eletrodo central (3) e do lateral (4), o que ocorre ordinariamente. Em condições especiais de funcionamento do motor pode ter falhas na ignição promovida pela carência de centelhamento, por "flash over", devido a uma série de fatores, tais como aumento excessivo de temperatura de operação ou impregnação de corpos estranhos na superfície do verniz ou problema de qualidade estrutural no tocante à resistência, obstando centelhamento normal. Há, por outro lado o fator impeditivo do uso de verniz com chumbo, largamente em uso corrente, principalmente, pela questão ambiental. A presente invenção visa substituir o chumbo com outros elementos na constituição do verniz, em quase sua totalidade, e ao mesmo tempo aumentar a performance da vela de ignição pertinente à ignição pelo centelhamento."Spark plug". The present invention relates to the spark plug used, for example, in the internal combustion engine for automotive vehicles. The spark plug precipitously consists of the metallic bonnet (1), which attaches as a contact pole, houses an alumina-based ceramic insulator (2) and in which the central electrode (3) is protected. The tension between the center electrode (3) and the side electrode (4), which is the extension of the bonnet (1), is applied to import sparks into the gap (g) between the end of the central electrode (3) and the side. (4), which occurs ordinarily. Under special engine operating conditions you may experience ignition failures due to lack of sparking, flash over due to a number of factors such as excessive operating temperature increase or impregnation of foreign bodies on the varnish surface or problem. structural quality with respect to resistance, preventing normal sparking. There is, on the other hand, the impeding factor of the use of lead varnish, largely in current use, mainly due to the environmental issue. The present invention aims at replacing lead with other elements in the constitution of the varnish almost in its entirety and at the same time increasing the performance of the spark plug pertinent to spark ignition.
