Abstract

<B>MéTODO DE CONTROLE DE UM SENSOR LINEAR DE OXIGêNIO<D> no qual o sensor (1) é locado ao longo de um duto de exaustão (2) de um motor de combustão interna (3) para receber em uma câmara separada (4) parte dos gases de exaustão e gerar um primeiro sinal (Vd) representativo da oscilação entre a composição de gases na câmara (13) e uma composição de referência estequiométrica; o primeiro sinal (Vd) sendo processado por circuito retroativo (15, 17, 19, 22) o qual controla uma corrente elétrica (lp) ao sensor (1) de tal maneira a gerar um mecanismo de drenagem de ions de oxigênio rumo a câmara (13) e para cancelar a oscilação; a corrente (lp) sendo convertida em um sinal de saída (Vout~ m~) o qual salva um erro devido a diferença de corrente (lp), sendo proporcional a quantidade de oxigênio presente nos gases de exaustão; o método apresentando a fase de cálculo (100, 110, 120) de um parâmetro de correção (kcorr) o qual é aplicado ao sinal de saída (Vout~ m~) para fazer o mesmo efetivamente proporcional a quantidade de oxigênio presente nos gases de exaustão; o cálculo do parâmetro (Kcorr) sendo efetuado com o sensor (1) localizado em uma atmosfera controlado por meio de processamento de um sinal externo (Vout~ m~) e por uma voltagem nominal (Vnom) definindo o valor teórico do sinal de saída (Vout~ m~) na presença de dita atmosfera controlada.
