The Euro 6 standard has applied throughout Europe for type tests of new cars since September 1, 2014 and since September 1, 2015 is binding on all newly registered vehicles. Further it has meanwhile been extended with further steps. As part of a Euro 6 c level RDE legislation (Real Driving Emissions) was produced.. The  RDE regulation became binding on new types of vehicle from September 2017 onwards, and for all new vehicles two  years later.

Above all with regard to nitrous oxide emissions, the RDE legislation is regarded as the greatest challenge facing diesel vehicles since the introduction of EU exhaust emissions standards. In addition to a further reduction in engine-out emissions, two systems have proven effective in reducing nitrous oxides for almost one decade now, depending on the vehicle weight and its engine: the NOx storage catalytic converter (NSC or LNT) and selective catalytic reduction, abbreviated as: SCR.

In SCR technology, aqueous diesel exhaust fluid, AdBlue® is injected into the exhaust stream using injection technology. Ammonia is released and, in the subsequent SCR catalytic converter, it reduces up to 80 percent of the nitrous oxides (NOx) into harmless nitrogen (N2) and water (H2O). Diesel models equipped in this way comply with the values of the Euro 6 exhaust emission standard with NOx post-treatment. AdBlue® is a significant component of this highly efficient and clean drive concept. SCR technology and AdBlue® have laid the foundation in vehicle technology for diesel-powered commercial vehicles to reduce their pollution emissions – especially of nitrous oxides.

In heavy vehicles, AdBlue® has proven itself as an effective solution for post-treatment of exhaust gases and is in widespread use. AdBlue®’s time has now also come for diesel-driven passenger cars. This is because a significant proportion of diesel cars that comply with the Euro 6 exhaust emission standard are  equipped with an SCR system.

. AdBlue® consumption depends on the vehicle weight and the individual driving style. On average, a car will consume about 1.5 liters per 1,000 kilometers.

The AdBlue® brochure published in German and English offers an overview of the product, its operating method, handling and infrastructure questions for anyone who is interested. The AdBlue® flyer contains all important information about the product and its practical handling in a clearly laid-out format for anyone who is interested. The flyer is also available in German and English.
