Abstract

DISPOSITIVO ELETRôNICO PARA O CONTROLE DA RELAçãO AR/COMBUSTíVEL DA MISTURA FORNECIDA A UM MOTOR DE COMBUSTãO INTERNA. Dispositivo de controle no qual um sensor linear de oxigênio 20 disposto no duto de exaustão de gases 5 de um motor a combustão interna 2 a montante de um conversor catalítico 8 gera um sinal fornecido a um circuito de conversão que gera um sua saída um parâmetro medido <sym>m representado a relação ar/combustível da mistura fornecida ao motor 2. O parâmetro medido <sym>m é comparado com um parâmetro alvo <sym>o de forma a calcular um parâmetro de erro o qual é usado, de acordo com o método de operação, quando necessário, para gerar um sinal simulado variável entre um valor positivo de saturação P1 e um valor negativo de saturação -P1 de forma a modelar a saída de um sensor de oxigênio de tipo on/off. O sinal simulado é também processado de forma a calcular um parâmetro de correção (KO2) destinado a ser utilizado para a correção de um valor teórico Qb de uma quantidade calculada de combustível 40, obtendo uma quantidade corrigida de combustível Qbt de um sistema de injeção 10 do motor.
