Abstract

resumo “sistema de controle de motor de combustão interna” a presente invenção se refere a um dispositivo de controle para um motor de combustão interna, o referido dispositivo de controle implementando um controle pobre, com o que a relação de ar para combustível do gás de exaustão que flui para dentro de um catalisador de purificação de exaustão é ajustada para uma relação de ajuste de ar para combustível pobre, e a controle rico, com o que a relação de ar para combustível do gás de exaustão que flui para dentro do catalisador de purificação de exaustão é ajustada para uma relação de ajuste de ar para combustível rica. quando a quantidade de oxigênio absorvido pelo catalisador de purificação de exa-ustão durante o controle pobre alcança ou excede um critério de quantidade de ar-mazenamento, um controle é executado para alternar para o controle rico. adicio-nalmente, a controle é executado para ajustar a relação de ajuste de ar para com-bustível pobre para uma primeira quantidade de entrada de ar de modo a ser mais rica do que a relação de ajuste de ar para combustível pobre para a segunda quan-tidade de entrada de ar que é menor do que a primeira quantidade de entrada de ar.
