METHOD AND DEVICE FOR REDUCING THE EMISSIONS OF NITROGEN OXIDES AND AMMONIA IN AN EXHAUST GAS POST-PROCESSING SYSTEM OF A HEAT ENGINE DURING CHARGE ALTERNATIONS

摘要

The invention relates to a method and an apparatus for the reduction of nitrogen oxide emissions in the exhaust of an internal combustion engine, wherein in a powered with the internal combustion engine vehicle data to a route in a navigation system and / or at least one driver assistance system can be provided. According to the invention, Ss is provided that even in transient operating conditions of the engine from the data of the expected route, an engine-load profile and thus a nitrogen oxide emission of the internal combustion engine, a nitrogen oxide conversion of the catalyst and / or a need of the metered for nitrogen oxide reduction are predicted and this data are considered correctively in the dosage of Reduktionsmittell or the timing and duration of loading and regeneration phase of the NOx storage catalytic converter can be influenced.
