| description | Use of catalytically active particle filters containing a filter body and a catalytically active coating, which consists of two layers, where the second layer is directly contacted with the incoming exhaust gas and the first layer is completely covered on exhaust gas side, and both layers contain aluminum oxide, where the aluminum oxide in the first layer is catalytically activated with palladium during which second layer contains rhodium as catalytically active components, for removing of particles, carbon monoxide, hydrocarbon materials and nitrogen oxide from the waste gas. Use of catalytically active particle filters containing a filter body and a catalytically active coating, which consists of two layers arranged one above the other, where the second layer is directly contacted with the incoming exhaust gas and the first layer is completely covered on exhaust gas side, and both layers contain aluminum oxide, where the aluminum oxide in the first layer is catalytically activated with palladium during which second layer contains rhodium as catalytically active components, and only the second layer additionally contains an oxygen-storing cerium/zirconium mixed oxide, for removing of particles, carbon monoxide, hydrocarbon material and nitrogen oxide from the waste gas by internal combustion engine operated with stoichiometric air/fuel mixture. Independent claims are included for: (1) use of an exhaust gas purification device for cleaning of exhaust gas by internal combustion engine operated with stoichiometric air/fuel mixture, comprising the catalytically active particle filters, which are arranged close to the engines; and (2) purification of exhaust gas by internal combustion engine operated with stoichiometric air/fuel mixture, comprising conducting the exhaust gas over the catalytically active particle filters for removing of carbon monoxide, hydrocarbon material, nitrogen oxide and particles. |
