Thanks to BMW BluePerformance technology, it is possible to further optimise the emissions response of diesel engines. In addition to the diesel particulate filter and oxidation catalytic converter, there is also a NOx catalyst storage which further reduces the level of nitrogen oxide in the exhaust gas. The combustion process itself is not affected and the diesel engines’ high degree of efficiency is preserved.
With some models, an additional method of nitrogen oxide reduction is used: the SCR catalytic converter (SCR = Selective Catalytic Reduction) with AdBlue® injection. A chemical reaction triggered by injecting the AdBlue® solution greatly reduces nitrogen oxide emissions.
This enables the diesel models to already meet the requirements of the EU6 emission norm that comes into effect in 2014. You can refill the AdBlue® solution yourself or can arrange an appointment with your BMW Service Partner. Continue reading
