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. However, in commercial trucking, the ability to reduce emissions to near-zero levels while also delivering 3-5% fuel savings distinguishes SCR as one of the only emissions control technologies that are as good for business as it is for the environment.
SCR technology is designed to permit NOx reduction reactions to take place in an oxidizing atmosphere. It is called “selective” because it reduces NOx levels using ammonia as a reductant within a catalyst system. 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 every day. The reductant source is usually automotive-grade urea, otherwise known as DEF, which can be rapidly hydrolyzed to produce the oxidizing ammonia in the exhaust stream. SCR technology alone can achieve NOx reductions in excess of 90%.
