What is AdBlue

AdBlue ®, also known as AUS 32, is a high purity chemical solution, comprised of 32.5% urea and 67.5% de-ionized water. Urea is produced by the synthesis of ammonia and CO2 (carbon dioxide). AdBlue ® is produced from Automotive grade Urea, a particularly pure grade of Urea, with low levels of metals, minerals, and other substances potentially harmful for the SCR system and catalyst. It is important to only buy products named AdBlue ®, manufactured according to the ISO 22241 standard. AdBlue ® is a registered trademark of the VDA (Verband der Automobilindustrie). VDA offers further information on its website www.vda.de under the theme “AdBlue ®” with a current list of licensees. Only buy AdBlue ® from a company that appears in the licensees list, or from a distributor of those brands.

SCR Technology

“SCR” stands for Selective Catalytic Reduction. It’s the name of a post-combustion technology treatment for diesel engines, which allows them to reduce their harmful emissions of NOx (nitrogen oxides). This technology was first introduced in the 80’s; power plants, cement , waste incinerators, glass factories and refineries have been utilizing an ammonia based reagent in a stationary SCR system to reduce NOx emissions in the atmosphere. During the years the size of the SCR system has been reduced and adapted to diesel vehicles. Moreover, instead of ammonia (dangerous and not easy to handle), the system now utilize Urea, ammonia safe carrier, diluted in de-ionized water. Almost all of the main engine manufacturers use this technology to meet the requirements of new legislation on NOx (Nitrogen oxides) emissions.

euro standards legislation

The European Parliament has introduced Emission control Standards
Euro 1 for Passengers cars and light commercial vehicles and Euro I for heavy duty trucks in 1992. During the following years more stringent regulations (Euro II and III) have lowered the limits of polluting agents in diesel engines emissions. With the introduction of Euro IV regulation for heavy duty truck in 2005 the limits were dramatically reduced; many engine producers have chosen to adopt SCR technology using AdBlue® in order to meet the new emission standards without compromising engine performance. Euro V standard introduced in 2008 has further reduced those limits.

Current legislation Euro VI has brought the limits to an outstanding reduction of 80% for NoX (Nitrogen Oxides) and 66% for PM (Particulate Matter) compared with previous limits. The new Standard has become effective on January 1st 2014.
