Abstract
A catalytically active diesel particulate filter with ammonia trap action is presented, which, in addition to an oxidation-active coating (), comprises a coating () which is catalytically active in the SCR reaction. By means of this inventive diesel particulate filter, it is possible to make exhaust gas aftertreatment systems for removing nitrogen oxides and particulates from the exhaust gas of lean engines considerably simpler and less expensive.
