aftermarket scr system
The aftermarket SCR system, or Selective Catalytic Reduction system, is a highly advanced emissions control device designed to reduce nitrogen oxide (NOx) emissions in diesel engines substantially. Its chief functions are to inject a liquid reducing agent into the exhaust stream that reacts with NOx over a catalyst and changes them into harmless nitrogen and water vapour. Mechanical features of the SCR system include accurately dosing the reductant, sophisticated thermal management for the best operation of catalysts and on-line monitoring of emissions levels. This system is commonly put into use with heavy goods vehicles such as trucks and buses, where it has become increasingly important in relation to environmental legislation. As an effective way to improve air quality and cut down on transport greenhouse gas emissions, the aftermarket SCR system is a vital supply for sustainable transportation.
