METHOD AND DEVICE FOR CATALYTIC REMOVAL OF A POLLUTANT CONTAINED IN THE EXHAUST GAS OF AN INTERNAL COMBUSTION SYSTEM

The method and the device are configured for the catalytic removal of a pollutant contained in an exhaust gas of a combustion system using a reagent. A temporal mean, or time average, is formed for the concentration of the pollutant in the exhaust gas. The catalytic converter is laid out for complet...

Beschreibung
Zusammenfassung:	The method and the device are configured for the catalytic removal of a pollutant contained in an exhaust gas of a combustion system using a reagent. A temporal mean, or time average, is formed for the concentration of the pollutant in the exhaust gas. The catalytic converter is laid out for complete conversion if the reagent is introduced stoichiometrically. Here, the reagent is introduced in substoichiometric proportions with respect to the time average of the pollutant content.
