Abstract

filtro de partículas. um objetivo da invenção é eliminar o depósito dos resíduos de combustão em um filtro de partículas com fluxo na parede enquanto reduzindo as quedas na taxa de captura da pm. para atingir o objetivo acima, a invenção apresenta um filtro de partículas com fluxo na parede delimitado por paredes de divisão porosas tendo poros de um tamanho que permite que os resíduos e os agregados dos resíduos atravessem. no filtro, uma camada de cobertura tendo poros menores do que os poros das paredes de divisão são fornecidos em uma região das paredes de divisão, de uma extremidade a montante sua até uma posição antes de uma extremidade a jusante sua.
