Exhaust aftertreatment system for treating exhaust gas of diesel engine of mobile working machine e.g. crane, has first feed system that is provided for supplying precursor product of reducing agent to exhaust gas

The exhaust aftertreatment system has a catalyst (2) that is provided for converting nitrogen oxide by reacting nitrogen oxide contained in the exhaust gas with a reducing agent such as ammonia to the exhaust gas added. A first feed system (4) is provided for supplying a precursor product of a reduc...

Beschreibung
Zusammenfassung:	The exhaust aftertreatment system has a catalyst (2) that is provided for converting nitrogen oxide by reacting nitrogen oxide contained in the exhaust gas with a reducing agent such as ammonia to the exhaust gas added. A first feed system (4) is provided for supplying a precursor product of a reducing agent to the exhaust gas. A second feeding system (5) is provided for the direct supply of the reducing agent to the exhaust gas. The first feed system is provided with a first metering system (6) for metering a quantity of the exhaust gas added previous product. Independent claims are included for the following: (1) a mobile working machine; and (2) a method for operating exhaust gas aftertreatment system. Die vorliegende Erfindung betrifft ein Abgasnachbehandlungssystem mit einem Katalysator (2) zur Umwandlung von NOx durch Reaktion von im Abgas enthaltenem NOx mit einem dem Abgas zugegebenen Reduktionsmittel, mit einem ersten Zuführungssystem (4) zur Zuführung eines Vorgängerprodukts des Reduktionsmittels zum Abgas, und mit einem zweiten Zuführungssystem (3) zur direkten Zuführung des Reduktionsmittels zum Abgas.
