Abstract

"AQUECEDOR CERâMICO E VELA DE INCANDESCêNCIA CERâMICA". A presente inveção refere-se ao aquecedor cerâmico (1) a ser utilizado nas velas de incandescência cerâmicas, que são montadas no motor a diesel. Convencionalmente a vela de incadescência cerâmica a ser fixada no motor a diesel é notório aquele constituído de corpo do aquecedor cerâmico isolante revestido de cilindro externo metálico e de aquecedor resistivo metálico ou não e de fio para puxamento do eletrodo nele inserido, cuja estrutura apresenta em 2 grupos, ou seja, aquele que possui o intervalo entre o eixo central com uma das extremidades soldadas dentro do castelo metálico da vela incadescência e o fio de ligação para puxamento do eletrodo do aquecedor cerâmico é intermediado pelo resistor para controle da temperatura, e aquele, o eixo central diretamente ligado ao fio de ligação. O primeiro permite estabelecer uma elevação rápida de temperatura do aquecedor resistivo inserido e também, gerar um calor suficiente para a partida do motor, porém o custo de fabricação lhe é elevado, e já o segundo não se condiz com o desenvolvimento rápido da elevação de temperatura proporcionada pelo aquecedor resistivo embutido no corpo do aquecedor resistivo embutido no corpo do aquecedor cerâmico, trazendo-nos problemas em ambos os casos. A presente invenção com a introdução da relação de estabelecimento da dimensão entre o comprimento do aquecedor resistivo (6") inserido no corpo do aquecedor cerâmico (2) no sentido axial do aquecedor cerâmico (1) e o comprimento do aquecedor resistivo (6") da parte do cilindro externo metálico (4), que fixa o dito corpo de aquecedor cerâmico (2) resolve os problemas citados.
