Exhaust treatment device and method to operate an exhaust treatment device

摘要

The catalyst (10) for the reduction of it components the exhaust gas of the internal-combustion engine is arranged by the waste gas system pre-aged a conditioning unit (11) and marked by the metering unit (12) to proportioned bringing of the agent into the catalyst. The element (14) exhibits a distance, which is co-coordinated with a cell density of the catalyst. The metering unit exhibits current up the discharge opening channels (16) a cavity (17) for the uniform distribution of the agent. An independent claim is also included for a method for the operation of an exhaust subsequent treatment device by using the above device.
