DNOx®

DNOx® - an EGR-based emission control system

DNOx® is a low pressure EGR*-system which recirculates particulate free exhaust gas in order to, among others, reduce NOx by 40-50%. The reduction rate depends on engine characteristics and type of particulate filter.

DNOx® reduces legislated emissions:
Carbon Monoxide
Hydrocarbon
Particulate Matter
Nitrogen Oxides
CO
HC
PM
NOx

DNOx® is suitable for both OEM** and aftermarket installations and for different applications like trucks, buses and off-road machinery.

DNOx® has been delivered since 1999 to customers in Europe, Asia and USA.
