scr chemical reaction
In diesel engines, the SCR (Selective Catalytic Reduction) chemical reaction is used to reduce nitrogen oxide (NOx) emissions. Here, a liquid-reductant agent, usually urea, is injected into the exhaust stream upstream of a catalyst. The main functions include the breaking down of NOx into clean nitrogen and water vapor. Technological features include precise injection systems and advanced catalyst materials that make the reaction take place at ideal temperatures. Applications are wide-ranging in such industries as heavy-duty vehicles and power generation. Their objective is to meet steadily more stringent environmental regulations. The SCR system's efficiency and effectiveness have made it a cornerstone of clean energy technology. It offers sustainability without sacrificing power.
