Abstract
"ESTRATéGIA EMPREGANDO CONTRAPRESSãO DE EXAUSTãO PARA QUEIMAR FULIGEM CAPTURADA POR UM FILTRO DE PARTICULADO DE DIESEL". Um sistema de exaustão (16) de um motor a diesel (10) tendo um filtro de particulado de diesel (18) para tratar gás de exaustão. Quando a fuligem capturada acumulou na medida em que pode afetar o desempenho do filtro, um sistema de controle de motor (12) força a combustão de fuligem capturada aumentando a contrapressão de exaustão usando um dispositivo de controle (20) tal como uma válvula de controle de contrapressão ou palhetas de um turbocompressor de geometria variável.
