Auto SCR System Market Size, Share, Trend & Global Industry Analysis By 2032 | IMR

Diesel engines have the Auto SCR (Selective Catalytic Reduction) as its emissions control technology to lessen the nitrogen oxide (NOx) emissions. It works by injecting DEF, the urea-based solution into the exhaust stream. DEF reacts with NOx in the presence of a catalyst and this changes NOx to water and nitrogen which both have reduced environmental pollution. To meet tough emission standards modern diesel vehicles and machine equipment of today are equipped with SCR systems as a rule.
