scr system in diesel engines
The Selective Catalytic Reduction (SCR) system is one of the most important elements in today's diesel engines. It has been developed principally to reduce emissions. It's job is mainly to decompose nitrogen oxides (NOx), harmful pollutants into harmless nitrogen and water. To achieve this, a urea-based liquid is injected and reacts with the nitrogen oxides in a catalytic process. Def fluid, which is commonly called Diesel Exhaust Fluid (DEF) can be used. Technological features include def precise injection, a catalyst design which is ideal for very high conversion rates and integrated sensors that monitor and control the process. SCR systems can be found on heavy-duty vehicles of all kinds, ranging from trucks to tour buses. It is essential for them to comply with rigorous emission regulations as well. Off-road vehicles and industrial equipment also make use of SCR systems. Wherever they are used it reduces dramatically their environmental effects.
