Abstract
aparelho de controle de quantidade de injeção de combustível para um motor de combustão interna. a presente invenção refere-se a um aparelho de controle de quantidade de injeção de combustível de uma modalidade de acordo com a presente invenção que compreende um sensor de razão ar-combustível 56 que fica disposto entre uma porção agregada de gás de descarga hk e um catalisador de três vias (43), e que emite um valor de saída correspondente a uma quantidade de oxigênio e uma quantidade de substâncias não queimadas contidas em um gás de descarga que atingge uma camada de eletrodo de lado de gás de descarga através de uma camada porosa (camada de resistência de difusão). esse aparelho de controle obtém uma razão ar-combustível detectada real ao corrigir o valor de saída do sensor de razão ar-combustível (56) com base em uma concentração de álcool de um combustível detectado pelo sensor de concentração de álcool (59) e um valor de indicação de desequilíbrio de razão ar-combustível que representa um grau de não uniformidade entre razões ar-combustível cilindro por cilindro. o aparelho de controle controla por realimentação uma quantidade de combustível de modo que a razão ar-combustível detectada real coincida com um valor almejado.
