AdBlue®-Diesel Exhaust Fluid (AdBlue) packaging container

What is AdBlue?

Diesel engines are now required to meet tough NOx standards to help control air pollution. The preferred method involves injecting a high purity fluid called Diesel Exhaust Fluid (AdBlue) into the exhaust system.

AdBlue is used by modern diesel engines which use Selective Catalytic Reduction (SCR) to control NOx emissions. SCR is the leading technology in emission regulations. It has been successfully used in Europe for several years and can now be seen as standard on the following – VW, BMW, Mecedes Benz, Opel, Ford, Toyota and Peugeot.

How does an SCR System Work?

The purpose of the SCR system is to reduce levels of Nox that are harmful to our health and our environment. The AdBlue is injected as a fine mist into the exhaust stream where a chemical reaction takes place in the presence of a catalytic converter to convert the nitrogen oxides to inert nitrogen gas.

AdBlue® is a high purity operating fluid, used in the emissions removal systems of diesel engined vehicles and equipment. Chemically speaking AdBlue® is a 32.5% solution of Urea in purifed water. The AdBlue® is stored in a tank on the vehicle and from there dosed automatically by the ECU directly into the exhaust gas at a rate in relation to the amount of Nitrous Oxides (NOx) being produced by the engine. Following mixing, the AdBlue® and exhaust gas mixture passes into a catalyst system where a chemical reaction takes place converting the NOx to harmless Nitrogen and Water, which are then expelled from the end of the exhaust. During the reaction the AdBlue® is consumed and needs to be replaced by refilling the tank periodically. AdBlue® consumption is related to engine load, engine size, travelling terrain and temperature.
