The Product:
Diesel Exhaust Fluid (DEF) is a urea-based fluid specifically engineered for diesel engines as the reducing agent in Selective Catalytic Reduction (SCR) systems, which is a new vehicle technology platform for reducing NOx emissions through exhaust after treatment. DEF is a solution made up of purified water and 32.5 percent urea that is used as a carrying agent for the ammonia needed to reduce nitrogen oxide (NOx) emissions from diesel engines into nitrogen, water and carbon dioxide (CO2).
