Diesel Exhaust Fluid is a solution used in Selective Catalytic Reduction (SCR) systems on diesel engines to reduce nitrogen oxide (NOx) emissions. It is a non-toxic, colorless liquid composed of purified water and urea. The urea concentration is typically around 32.5% by weight.
This fluid’s primary benefit lies in its ability to significantly lower harmful pollutants released into the atmosphere, contributing to cleaner air and improved environmental health. Its implementation has become increasingly important due to stricter emissions regulations imposed on diesel vehicles and equipment globally. Historically, the need for such a fluid arose from efforts to combat the detrimental effects of NOx on air quality and public health.
