ABSTRACT:
An open particulate trap for purifying exhaust gases from mobile internal combustion engines includes at least one at least partially structured metal foil and at least one high-temperature-resistant fiber layer having metal fibers defining the open particulate trap for purifying exhaust gases from mobile internal combustion engines. The fiber layer has a section and, at least in the section, a catalytically active coating being an SCR catalyst. An exhaust system of an automobile internal combustion engine includes an exhaust pipe defining a flow direction and at least the following components disposed in succession in the flow direction: a reducing-agent feed for supplying liquid urea and the particulate trap.
