What does diesel exhaust fluid do?


Ultraclear Diesel Exhaust Fluid (DEF) is a urea-based fluid engineered for diesel engines as the reducing agent in Selective Catalytic Reduction (SCR) systems. SCR systems have been installed to meet all EPA2010 standards on diesel engine vehicles since March or 2010.  This system is a new effort to protect the environment decreasing harmful exhaust emissions and increasing diesel engine performance. 

An SCR system is a diesel engine vehicle technology dedicated to reducing environmentally harmful NOx emissions through exhaust after treatment.  A mist for DEF is injected into the SCR system.


Once the diesel fuel has gone through the engine and is on its way out the exhaust pipe it now first passes through the SCR system to be treated. The treatment is a special fluid (DEF) that must combined with the burned exhaust gasses to form a chemical reaction. This chemical reaction dramatically reduces environmentally harmful pollutants, specifically nitrogen oxide. 


DEF is a solution made from purified water and 32.5 percent urea formulation that is used as a carrying agent for the ammonia needed to reduce nitrogen oxide (NOx). DEF is stored onboard the vehicle and used at a rate of consumption of approximately 2%-4% of diesel fuel consumption.  


Through this process of introducing diesel exhaust fluid in the SCR system a significant amount of harmful gasses are virtually turned into welcomed gases such as pure nitrogen, water and carbon dioxide (CO2).
