Abstract

método para determinação de uma resistência de fluxo através de um filtro particulado (3) localizado a jusante de um motor de combustão interna (1) em um sistema de exaustão. o método compreende um primeiro diferencial de pressão (¿p1) sobre o filtro particulado, medição de um segundo diferencial de pressão (¿p2) a jusante do filtro particulado, determinando uma razão de pressão (¿p1/¿p2) entre primeiro diferencial de pressão e o segundo diferencial de pressão, e a partir da dita razão de pressão, determinar uma resistência de fluxo sobre o filtro particulado. o segundo diferencial de pressão é medido sobre um sistema de redução catalítica seletivo (4).
