AdBlue®-powered diesel models are better for the environment
The Euro VI European standard has imposed even stricter limits on nitrogen oxide emissions
The European Union regulates CO2 and nitrogen oxide emissions from a variety of sources in order to protect the environment. “Euro standards” are regulations that impose limits on harmful gas emissions for motor vehicles. The first standard, Euro I, affected vehicles put into circulation on 1st January 1993. Subsequent revisions have lowered the acceptable levels of emissions. Today, the Euro VI c standard establishes a threshold of 80 mg/km for nitrogen oxide emissions for diesel vehicles. To meet these ever stricter requirements, manufacturers are turning more and more to SCR (Selective Catalytic Reduction) technology that works with AdBlue®. Ultimately, this technology will be the only one that enables diesel vehicles to stay within the limits set by the European standard.
How AdBlue® helps diesel vehicles cause less pollution
AdBlue® is injected into the exhaust pipe between a car’s engine and SCR catalyst to help diesel vehicles stay within the limits for nitrogen oxide (NOx) emissions. At high temperatures, this colourless liquid turns into ammonia and carbon dioxide. The nitrogen oxides react inside the catalyst with the ammonia, and the NOx molecules are converted into nitrogen (N2) and water (H2O): NOx + NH3 = H2O + N2.
