Selective Catalytic Reduction (SCR) is one of the most cost-effective and fuel-efficient vehicle emissions control technologies available to reduce diesel engine emissions. For passenger cars and light duty trucks, the ability to meet strict emissions and fuel efficiency guidelines affordably without compromising driving power and performance is attractive. In commercial trucking, the ability to reduce emission to near-zero levels while also delivering a 3-5% fuel saving distinguishes SCR as one of the only emissions control technologies that is as good for business as it is for the environment.

SCR technology is designed to permit nitrogen oxide (NOx) reduction reactions to take place in an oxidizing atmosphere. The reducing agent reacts with NOx to convert the pollutants into nitrogen, water and tiny amounts of carbon dioxide (CO2) – natural elements common to the air we breathe everyday. The reductant source is usually automotive-grade urea, otherwise known as Diesel Exhaust Fluid, which can be rapidly hydrolyzed to produce the oxidizing ammonia in the exhaust stream. SCR technology along can achieve NOx reductions in excess of 90%.

SCR will reduce:

  • NOx emissions by up to 90%
  • Hydrocarbons (HC) and carbon monoxide (CO) emissions by 50-90%
  • Particulate matter (PM) emissions by 30 – 50%

Using Diesel Exhaust Fluid (DEF) to convert NOx emissions into pure nitrogen and water vapor, two natural component of the air we breathe, SCR systems can also be combined with a diesel particulate filter (DPF) to achieve even great emissions reductions for PM.
