In order to purify the air and clean the environment, a technology called SCR (Selective Catalytic Reduction) is introduced. It is a clean, simple and reliable technology because:
1.Clean: It is certified by the U.S. Environmental Protection Agency (EPA or USEPA) and meet all its new standards.
2.Simple: It is built on the base of existing technology and simply adds an exhaust fluid to exhaust system for reducing harmful particulates.
3.Reliable: Since 2006, Europe is using SCR technology. Over 6000,000 commercial vehicles with SCR technology are running in Europe. Now it is spreading across North America.
SCR system inject Diesel Exhaust Fluid (DEF) into the exhaust gas and then filters it with the help of a catalyst. In this way, the harmful oxides of Nitrogen (NOx) are reduced into nitrogen and water.
DEF is an aqueous solution which is composed of 32.5% pure urea and 67.5% deionized water. People often have misconceptions that DEF is a fuel additive. However, it is never added to…
