Diesel Exhaust Fluid (DEF) is often referred to as AdBlue® in Europe and other markets. AdBlue®/DEF is required by many modern diesel engine applications using selective catalytic reduction (SCR) technology to reduce the levels of oxides of nitrogen emitted by an exhaust system.
AdBlue® is used worldwide for the purification of motor vehicle exhaust emissions. The product is a clear, non-toxic urea solution (AUS 32), and its use is both safe and environmentally friendly. AdBlue® is stored separately in proximity of the diesel tank; it is not added to the diesel fuel.
In order to be used in Euro 6 diesel engines, AdBlue® needs to meet the BS ISO 22241 specifications, which it does by having the required physical properties and chemical properties. The table below illustrates the properties AdBlue® needs to have.
Auditing and certification of AdBlue® manufacturers. In SCR systems (SCR=selective catalytic reduction), the chemical synthesis product urea AUS 32 (AdBlue®) is used to reduce NOx exhaust gases. For the worldwide distribution of urea AUS 32, the VDA has registered the trademark “AdBlue®” in all relevant automotive markets.
AdBlue is a diesel exhaust fluid (DEF) used in vehicles with Selective Catalytic Reduction (SCR) technology to reduce harmful gases being released into the atmosphere. AdBlue is a 32,5 % solution of high-purity, synthetically manufactured urea in de-mineralized water. It is a safe-to-use fluid.
