Abstract

CONTROLADOR DE SUPRIMENTO DE COMBUSTÍVEL PARA UM MOTOR DE COMBUSTÍVEL FLEXÍVEL. Um controlador de suprimento de combustível para um motor de combustível flexível no qual, quando uma mudança significativa na emissão de um sensor de concentração de álcool (25) é reconhecida e as condições de retroalimentação de proporção de ar-combustível são satisfeitas, uma seção de determinação de suprimento de combustível restante (41) determina que o combustível restante foi suprido, desde que a mudança significativa na emissão do sensor de proporção de ar-combustível (32) tenha continuado por um quarto período de limiar. Depois do reconhecimento da mudança significativa até a passagem do quarto período de limiar, a quantidade de suprimento básico Tm é convertida para a quantidade de suprimento convertido Tc com base em um valor de aprendizagem não atualizado; e depois da passagem do quarto período de limiar, a conversão é feita com base em um valor de aprendizagem atualizado, que é equivalente à concentração de álcool depois da mudança significativa.
