Abstract
APARELHO PARA CONTROLE DE GÁS DE ESCAPAMENTO PARA MOTOR DE COMBUSTÃO INTERNA. A presente invenção se refere a um controle rico para diminuir temporariamente uma proporção ar-combustível do gás de escapamento descarregado de uma câmara de combustão de motor que é realizado por um combustível adicional sendo injetado em um cilindro em um curso de expansão ou um curso de escapamento em um estado onde um grau de abertura do acelerador é comutado de um grau base de abertura do acelerador para um grau de abertura do acelerador para o controle rico e uma taxa EGR é comutada de uma taxa EGR para uma taxa EGR para o controle rico. O controle rico é terminado retornando o grau de abertura do acelerador (VTH) para o grau base de abertura do acelerador (VTHB), interrompendo a injeção do combustível adicional (Qa), e aumentando temporariamente a quantidade de um combustível principal (Qm). Então, um grau de abertura da válvula de controle EGR (VEGR) é controlado de maneira que a taxa EGR (REGR ) seja retornada para a taxa EGR base (REGRB).
