Beschreibung
Zusammenfassung:	An SCR exhaust gas aftertreatment device in which a urea-water solution is injected into an exhaust gas line (1) is provided. A component-a specific filter element lies in an area of an internal space (50), and is bounded by an elastomer membrane (42) that is embedded in a frost equalization foam (43). This prevents freezing damage even over a very long period of time and a large number of freezing cycles.
