Abstract

"VELA DE IGNIçãO". A presente invenção refere-se à vela de ignição utilizada para ignição de motores de combustão interna como motor de automóvel, etc. No estado da técnica, a vela de ignição provida do isolador (2) constituído de cerâmica à base de alumina, etc., alojado na parte interna do castelo metálico (1), onde é fixado o eletrodo de terra (4), e na parte interna do dito isolador (2) encontra-se inserido o eletrodo central (3). O isolador (2) está revestido de camada do vitrificante, composto de PbO, causador de poluição ambiental, e sujeito a situações como de elevação da temperatura da vela, aliada à elevação da umidade do meio, podendo ocorrer o fenómeno de descarga disruptiva (flasb over), perdendo a sua função primordial, que consiste na disposição da fonte de ignição da mistura na câmara de combustão. A presente invenção visa oferecer a vela de ignição provida de camada do vitrificante composto de uma quantidade desprezível de Pb, mas que pode ser vitrificado à temperatura relativamente baixa com excelente propriedade isolante, e além disso, provê facilidade em obter uma superfície vitrificada lisa, e promover a boa resistência mecânica do isolador com camada do vitrificante e obstando incidência de flash over.
