    摘要： The present invention relates to a particulate filter which comprises a wall flow filter of length L and three mutually different catalytically active coatings X, Y and Z, wherein the wall flow filter comprises channels E and A that extend in parallel between a first and a second end of the wall flow filter and are separated by porous walls forming surfaces OE and, respectively, OA, and wherein the channels E are gas-tightly sealed at the second end and the channels A are gas-tightly sealed at the first end, characterized in that the coating X is located in the porous walls, the coating Y is located in the channels E on the surfaces OE and the coating Z is located in the channels A on the surfaces OA.

    摘要： The invention relates to a particulate filter for removing particles, carbon monoxide, hydrocarbons and nitrogen oxides out of the exhaust gas of combustion engines operated with stoichiometric air/fuel mixture, comprising a wall flow filter with length L and a coating Z, wherein the wall flow filter includes channels E and A which extend in parallel between a first and a second end of the wall flow filter and are separated by porous walls, which form surfaces OE or OA, and wherein the channels E are closed at the second end and the channels A are closed at the first end, characterised in that coating Z is located in the porous walls and extends from the first end of the wall flow filter over the entire length L, and includes active aluminum oxide, two different cerium/zirconium/rare earth metal mixed oxides and at least one platinum group metal.

    摘要： The present invention relates to a particulate filter which comprises a wall-flow filter of length L and two different catalytically active coatings Y and Z, wherein the wall-flow filter comprises channels E and A that extend in parallel between a first and a second end of the wall-flow filter and are separated by porous walls which form the surfaces OE and OA, respectively, and wherein the channels E are closed at the second end and the channels A are closed at the first end, and wherein the coatings Y and Z have the same oxygen storage components and the same carrier materials for noble metals. The invention is characterized in that the coating Y is located in the channels E on the surfaces OE and the coating Z is located in the channels A on the surfaces OA.
