Abstract

resumo filtro de purificação de gás de escape um filtro de purificação de gás de escape (4) que é adequado para arranjo em uma passagem de escape de um motor de combustão interna e para coletar matéria particulada contida no gás de escape compreende: passagens de influxo de gás de escape e passagens de descarga de gás de escape que são dispostas de forma alternada; e divisórias porosas (6) que separam as passagens de influxo de gás de escape e as passagens de descarga de gás de escape uma da outra. cada uma das divisórias é dividida em uma zona revestida (cz) na qual uma superfície de uma base de divisória é revestida com uma camada de revestimento que tem um diâmetro médio de poro menor do que o diâmetro médio de poro da base de divisória e uma zona não revestida (ncz) que está localizada em um lado a jusante da zona revestida e em que uma superfície da base de divisória não é revestida com a camada de revestimento. um diâmetro de poro das divisórias é definido de tal modo que a cinza contida no gás de escape é capaz de passar através das divisórias na zona não revestida. uma resistência à passagem de uma porção de divisória localizada na zona revestida, a resistência à passagem estando em uma direção de espessura da porção de divisória localizada na zona revestida, é menor do que uma resistência à passagem de uma porção de divisória localizada na zona não revestida, a resistência à passagem sendo em uma direção de espessura da porção de divisória localizada na zona não revestida.
