Abstract

<B>"MéTODO PARA AVALIAR O COEFICIENTE ESTEQUIOMéTRICO PARA UM SISTEMA DE CONTROLE DE UM MOTOR DE COMBUSTãO INTERNA"<D> Trata-se de um método para avaliar o coeficiente estequiométrico do combustível para um sistema de controle de um motor de combustão interna que inclui um sensor de oxigênio (4, 26) disposto ao longo de um cano de escape (6) e aplica um sinal de composição (VI) e uma unidade de controle (5, 27) que inclui um controlador (10, 30) que fornece um parâmetro de controle (KO2) como uma função de uma magnitude de erro (VE, IE) e um bloco de avaliação (15, 31) que recebe um parâmetro de controle filtrado (KO2F) correlacionado com o parâmetro de controle (KO2), e fornece um coeficiente estequiométrico real (A/F)F. O método inclui os estágios de: detecção de um curso do parâmetro de controle filtrado (KO2F) (120-150, 220, 240) e cálculo do coeficiente estequiométrico real (A/F)F como uma função do curso detectado (160).
