AdBlue
Making diesel cleaner and more efficient.
Diesel exhaust fluid (DEF), commonly referred to as AdBlue in Europe and standardised as ISO 22241 is an aqueous urea solution made with 32.5% high-purity urea (AUS 32) and 67.5% deionized water. DEF is used as a consumable in selective catalytic reduction (SCR) in order to lower NOx concentration in the diesel exhaust emissions from diesel engines.
