SCR (Selective Catalytic Reduction System)
Principle of the SCR system(Reduction reaction by Urea)
1. Urea is injected by the Urea injection device.The Urea is decomposed into ammonia and carbon dioxide by the heat form exhaust gas.
2. Generated ammonia,nitrogen oxides and oxygen are decomposed into nitrogen and water by the catalyst in the reactor.
