Selective Catalytic Reduction (SCR)
Selective Catalytic Reduction (SCR) is the process by which nitrogen oxides (NOx) are removed from diesel engine exhaust gas. An aqueous solution of ammonia (AdBlue) is used to reduce nitrogen monoxide (NO) and nitrogen dioxide (NO2) converting them to water and nitrogen. This reaction occurs over a specially formulated catalyst in the SCR system.
When used in conjunction with a CRT® (Continuously Regenerating Trap) the combined Eminox SCRT® system can virtually eliminate Particulate Matter (PM) Hydrocarbons (HC) and Carbon Monoxide (CO) as well as reducing Nitrogen Oxides (NOx).
