NOx Exhaust Treatment System

NOx Exhaust Treatment System

The NOx storage catalyst, a combination of stainless steel catalytic converter and NOx storage components, allows nitrogen oxides to be temporarily stored. The resulting nitrogen oxides are oxidised to a higher valency and then removed from the exhaust gas flow.

At regular intervals, the nitrogen oxides stored in the converter are reduced to nitrogen and the catalyst is prepared for the next storage cycle.
