AdBlue®...what is it?
Adblue® is an ultra pure solution of urea in demineralised water, used in the new generation of commercial diesel vehicles for the removal of environmental pollutants.
Euro 4 emission regulations introduced from October 2006 further limit the amounts of Nitrous Oxides (NOx) and particulates that commercial diesel vehicles can emit. These limits will reduce again with the introduction of Euro 5 in October 2009.
To reach these standards, the majority of truck manufacturers have chosen the Selective Catalytic Reduction (SCR) system as a common solution. The fuel for the SCR system is called AdBlue®.
The good news for vehicle operators is that by using the SCR system the engine can be tuned for maximum fuel economy, extracting every last drop of energy from the fuel...giving a fuel saving that should be more than enough to cover the cost of the AdBlue®.
To protect the SCR system and keep the vehicle functioning correctly, the vehicle manufacturers have issued a standard specification, DIN 70070 for the quality of AdBlue®.
Urea is produced synthetically using Ammonia and Carbon Dioxide. Its main use is in fertilizers and chemical manufacture, but it is also found in everyday products such as hair conditioners, skin creams, food and adhesives.
