Abstract
"VELA DE IGNIçãO". A presente invenção refere-se à vela de ignição para motor de combustão interna utilizado nos veículos automotivos. No estado da técnica tem-se o isolador (2) constituído de cerâmica de alumina resguardado no castelo metálico (1) provido de eletrodo de terra (4) e dentro do isolador encontra-se inserido o eletrodo central (3), que se projeta num dos lados onde se desencadeia centelhas, quando se imprime a alta tensão, entre eletrodos, e no outro lado, do lado oposto, está o terminal onde se conecta a tensão requerida. O isolador (2) do lado do terminal é revestido da camada de verniz (2d) para eximir-se de "flash over" durante o funcionamento normal do motor além disso o verniz serve para adquirir lisura da superfície, que dificulta a impregnação de corpos estranhas e, podendo proporcionar-lhe vantagem no tocante ao ataque químico e aumento da resistência mecânica. Na composição do verniz tem sido largamente aplicado o composto de chumbo, que traz problemas ambientais, destarte a presente invenção visa substituílo ou reduzir sua presença drasticamente pela utilização de SiO~ 2~, B~ 2~O~ 3~, ZnO, BaO ou SrO, Al~ 2~O~ 3~, Na~ 2~O, K~ 2~O ou Li~ 2~O, de teor definido de modo que a rugosidade da superfície da camada revestida seja delimitada.
