Abstract
"ISOLADOR PARA VELA DE IGNIçãO E VELA DE IGNIçãO DOTADA DESTE ISOLADOR". A presente invenção refere-se à vela de ignição utilizada como fonte de ignição da mistura de ar e combustível do motor de combustão interna, e ao isolador utilizado para a vela de ignição. No estado da técnica, o isolador da vela de ignição, via de regra, é constituído de alumina (Al~ 2~O~ 3~) e os componentes de auxiliar de sinterização, compostos de SiO~ 2~, CaO e MgO, os quais formam dentro da estrutura a fase vítrea, subsidiando abaixamento da temperatura de sinterização. A formação aleatória da fase vítrea dentro do conceito traz problemas de isolação à alta temperatura, principalmente nos motores de alto desempenho em que exige isolação à alta temperatura, superior a 700 °C na câmara de combustão operando temperatura da reação de 2.000 a 3.000 °C, no tocante à ruptura dielétrica, em cujo ponto crítico reside o desempenho do isolador da vela de ignição. Embora haja patentes no sentido de superarem o impasse, persiste a questão da resistência às condições extremas de operação em relação alta isolação dielétrica dada a temperatura elevada. A presente invenção fundamentada na relação molar, óxido de alumínio e os componentes de auxiliar de sinterização estipulando determinada faixa, resolve-se a questão de modo satisfatório.
