METHOD FOR OPERATING AN EXHAUST GAS AFTERTREATMENT SYSTEM OF AN INTERNAL COMBUSTION ENGINE, AN EXHAUST GAS AFTERTREATMENT SYSTEM FOR AN INTERNAL COMBUSTION ENGINE, AND AN INTERNAL COMBUSTION ENGINE COMPRISING SUCH AN EXHAUST GAS AFTERTREATMENT SYSTEM

摘要

This version will replace all prior versions in the application: A method for operating an exhaust gas aftertreatment system of an internal combustion engine, wherein at least one operating parameter is detected during the operation of the exhaust gas aftertreatment system, the operating parameter being associated with an oxidation state of an SCR catalyst material of the exhaust gas aftertreatment system, and at least one measure for preventing an ongoing reduction of the SCR catalyst material and/or at least one reoxidizing measure for reoxidizing the SCR catalyst material is introduced in accordance with the at least one operating parameter.
