selective catalytic reducer
The selective catalytic reduction (SCR) is the most advanced emissions control technology at present which designed to dramatically reduce nitrogen oxide (NOx) emissions on diesel vehicles, while converting these harmful gases into harmless nitrogen and water during the operation. It does so by using a chemical process that converts these harmful gases into benign nitrogen and water anything else is left unrevealed. The primary functions of an SCR system are inject a liquid reductant agent into the exhaust stream to bind with the NOx, and then complete this conversion over a catalyst. The technological characteristics of SCR system include precise dosing and control systems to ensure that the proper amount of reductant is used for optimal conversion. SCR systems are widely used in the automotive industry, particularly in heavy-duty gasoline and diesel powered trucks, along with buses and farming equipment helping these industries to meet strict environmental regulations.
