Diesel Exhaust Fluid (DEF) is an aqueous solution used in Selective Catalytic Reduction (SCR) systems to lower Nitric Oxide (NOx) concentrations in the exhaust emissions. DEF is a stable, colourless, non-toxic, non-polluting and non-flammable substance that is classified as minimum risk for transportation.
