scr diesel exhaust
The SCR Diesel Exhaust or Selective Catalytic Reduction, is an advanced emissions control technology designed to reduce nitrogen oxide (NOx) emissions from diesel powered trucks and buses. This system breaks down NOx emissions into harmless nitrogen and water through a chemical reaction catalyzed by a catalyst. As a reductant, the system uses DEF (diesel exhaust fluid) which is added into the exhaust stream. Technological features of the SCR diesel exhaust include sophisticated sensors and control units which govern the process by which DEF is injected for optimal NOx conversion, as well as its rugged construction help to withstand harsh operation conditions. This technology is mainly used in the transportation field, especially heavy-duty diesel vehicles like trucks and buses and off-road equipment and Industrial machinery.
