Verfahren und Vorrichtung zur katalytischen Beseitigung eines Schadstoffes aus dem Abgas einer Verbrennungsanlage

摘要

The invention relates to a method and device for catalytically removing a pollutant from the exhaust gas (6) of an internal combustion system (1), whereby a predetermined quantity of a reactant (10) is added to the exhaust gas (6) according to a concentration of pollutant per unit of time, said concentration being pre-calculated using a characteristics map comprised of operational relevant parameters. In addition, the invention provides that the concentration of the pollutant in the exhaust gas (6) is determined using a sensor, and the concentration determined with an essentially constant pollutant emission in the operational states of the internal combustion system (1) is used to correct the characteristics map.
