Description
DEF (Diesel Exhaust Fluid) is an aqueous 32.5% nitrogen solution of high-purity urea in deionized water and is key components of selective catalytic reduction (SCR) systems, which help diesel vehicles meet stringent emission regulations. DEF is a liquid reducing agent that reacts with engine exhaust in the presence of a catalyst to convert smog-forming nitrogen oxides (NOx) into harmless nitrogen and water vapor.
