Abstract

SENSOR DE GáS, CONTROLADOR DE RAZãO AR-COMBUSTìVEL, E APARELHO DE TRANSPORTE. Trata-se de um sensor de gás que inclui uma seção de detecção de gás, um aquecedor cujo valor de resistência elétrica é alterado de acordo com a temperatura, e uma seção de controle disposta para controlar a operação do aquecedor e realizar o fornecimento de energia do aquecedor para aquecimento. A seção de controle inclui uma seção de fornecimento de corrente para fornecer uma corrente ao aquecedor em um período durante o qual o fornecimento de energia do aquecedor para aquecimento é interrompido, uma seção de detecção de voltagem disposta para detectar uma voltagem de ponta a ponta do aquecedor enquanto uma corrente está sendo fornecida ao aquecedor da seção de fornecimento de corrente, e uma seção de ajuste de corrente disposta para ajustar o nível da corrente, durante um período frio do aquecedor, que é fornecido da seção de fornecimento de corrente com base na temperatura ambiente e na voltagem de ponta a ponta do aquecedor como detectado pela seção de detecção de voltagem.
