The Euro VI European standard reinforces adoption of AdBlue® for diesel vehicles
Euro VI: do you understand the new regulations?
The new Euro VI regulation came into force in September 2015 and aims to reduce CO2 emissions and, above all, nitrogen oxide (also known as NOx) emissions for diesel passenger vehicles. The standard was ratified after additional evidence was put forward regarding health risks associated with urban air pollution linked specifically to NOx, and a disappointing reduction of these emissions in cities.
Emission limits have been reduced from 180 mg/km (Euro V) to 80 mg/km. This new regulation affects all models of vehicles released from September 2014 onwards, and all passenger cars from September 2015 onwards. By September 2017, new On-Board Diagnostics (OBD) systems, which manage all visual warnings for engine emissions and record any defects, will need to be updated to reflect stricter limits and monitor the new systems concerned.
How AdBlue® can help comply with these new regulations
AdBlue® works at the outlet from the diesel engine to purify the flow of exhaust gas containing pollutants such as nitrogen oxides. AdBlue® reacts with the nitrogen oxides to convert them into nitrogen and water. AdBlue® combined with an SCR (Selective Catalytic Reduction) tank can eliminate up to 95% of the nitrogen oxides contained in the exhaust gas at the engine outlet.
