Abstract

APARELHO DE CONTROLE DA RAZãO AR - COMBUSTìVEL E MéTODO DE CONTROLE DA RAZãO AR - COMBUSTìVEL PARA MOTOR DE COMBUSTãO INTERNA. é descrito um aparelho de controle da razão ar - combustível para um motor de combustão interna, em que uma quantidade de correção de alimentação, obtida de acordo com um desvio de uma razão ar - combustível em relação a uma razão ar - combustível estequiométrica, e uma quantidade de correção de realimentação, calculada com base em um valor de saída de um sensor de razão ar - combustível e sujeita a um processamento de segurança, são adicionadas a uma quantidade de injeção de combustível base correspondente à razão ar - combustível estequiométrica para decidir uma quantidade de injeção de combustível. Um limite superior e um limite inferior da quantidade de correção de realimentação são ajustados com base em uma concentração de álcool e na quantidade de correção de alimentação.
