The Relationship Between AdBlue & Euro 6 Standard

2020-08-04

Most countries and regions have enacted air quality protection standards that regulate vehicle pollutant emissions. The Euro standards (Euro 1 to Euro 6) regulate pollutant emissions from passenger cars. Manufacturers must comply with them to sell their vehicles in Europe.


Since September 2014 and the introduction of the Euro 6 standard, all new diesel passenger car are equipped with a nitrogen oxide (NOx) after-treatment system. The system most favoured by car manufacturers is the catalyst SCR (Selective Catalytic Reduction). This system works with AdBlue®, a product based on urea and demineralised water. Injected into the exhaust gases, AdBlue® reduces almost all nitrogen oxide emissions.





AdBlue® is a Diesel exhaust fluid for vehicles equipped with SCR technology. Made up of 67.5% deionized water and 32.5% high-purity urea, it meets the requirements of the ISO 22241 standard. AdBlue® is stored in an auxiliary tank separate from the Dieselfuel tank.
