SCR EXHAUST GAS AFTERTREATMENT DEVICE

摘要

An SCR exhaust gas aftertreatment device in which a urea-water solution is injected into an exhaust gas line is provided. At least one component of the device (e.g., a filter element) lies in an area of an internal space, and is bounded by an elastomer membrane that is embedded in a frost equalization foam. This prevents freezing damage even over a very long period of time and a large number of freezing cycles.
