Abstract

trata-se de um dispositivo de controle de razão entre ar e combustível que inclui um sensor de razão entre ar e combustível configurado de modo que um valor de corrente de saída do mesmo varie linearmente de acordo com uma concentração de oxigênio, e meios de controle de retroinformações de razão entre ar e combustível capazes de executar um controle de retroinformações de razão entre ar e combustível para controlar por retroinformações uma quantidade de injeção de combustível com base em um valor de detecção proveniente do sensor de razão entre ar e combustível de modo que o gás de escape de um motor de combustão interna alcance uma razão entre ar e combustível predeterminada. o dispositivo de controle de razão entre ar e combustível inclui, ainda, meios de proibição para proibir o controle de retroinformações quando a razão entre ar e combustível alcançar ou exceder uma razão entre ar e combustível rica predeterminada. o dispositivo de controle de razão entre ar e combustível permite o controle de retroinformações for a período predeterminado após a razão entre ar e combustível alcançar ou exceder a razão entre ar e combustível rica predeterminada.
