Abstract
resumo aparelho de controle de gás de exaustão para motor de combustão interna trata-se de um catalisador de três vias (20) e um catalisador de adsorção de nox (22) dispostos em uma passagem de exaustão de motor. em uma área de operação de motor de carga baixa predeterminada, a combustão em uma câmara de combustão (5) é executada em uma razão de ar-combustível de base pobre e uma razão de ar-combustível na câmara de combustão (5) é alterada para uma faixa rica no momento de descarga de nox do catalisador de adsorção de nox (22). em uma área de operação de motor de carga alta predeterminada, a razão de ar-combustível na câmara de combustão (5) é controlada para uma razão de ar-combustível teórica de uma maneira que envolve a retroalimentação. em uma área de operação de motor de carga intermediária predeterminada, a combustão na câmara de combustão (5) é executada na razão de ar-combustível base menor que a razão de ar-combustível base na área de operação de motor de carga baixa e a razão de ar-combustível na câmara de combustão (5) é alterada para a faixa rica com um período mais curto que um período rico da razão de ar-combustível para descarga de nox na área de operação de motor de carga baixa.
