Abstract (en)
A catalysed soot filter (10) comprises a filter body having a plurality of inlet channels (22) and outlet channels (24) separated by porous walls (16) and arranged so that particle-laden gas to be filtered is forced to flow from said inlet channels (22) to said outlet channels (24) through said porous walls (16). A catalyst coating is provided in said inlet channels (22) on said porous walls (16). The catalyst coating is applied in such a way that said inlet channels (22) comprise at least two channel portions (U,D) with a different catalyst content. <IMAGE>
