AdBlue is a high purity non-toxic solution of Urea in demineralised water used in the exhaust systems of Euro4 or Euro5 trucks to reduce harmful emissions. AdBlue is a trade mark owned by the VDA, most truck manufacturers use the SCR system which requires AdBlue. To protect the SCR system the vehicle manufacturers have issued a specification standard ISO 22241 for the quality of AdBlue.

AdBlue is stored in a separate tank on the vehicle. It is precisely metered into the hot exhaust manifold where the urea solution breaks-down into Ammonia and reacts with exhaust gasses in the presence of a catalytic converter. The oxides of nitrogen formed at combustion are converted into harmless elementary nitrogen and water. This method is called Selective Catalytic Reduction (SCR). It is a common misconception that AdBlue is a fuel additive.
