BlueTec is DaimlerChrysler's name for its two nitrogen oxide (NOx) reducing systems, for use in their Diesel automobile engines. One is a urea catalyst called AdBlue, the other is called DeNOx and uses an oxidising catalytic converter and particular filter combined with other NOx introduced the systems in the reducing systems. Both systems were designed to slash emissions further than ever before. Mercedes-BenzE-Class (using the 'DeNOx' system) and GL-Class (using 'AdBlue') at the 2006 North American International Auto Show as the E 320 and GL 320 Bluetec. This system makes these vehicles 45-state and 50-state legal respectively in the United States, and is expected to meet all emissions regulations through 2009. It also makes DaimlerChrysler the only car manufacturer in the the US committed to selling diesel models in the 2007 model year.

Efficient BlueTec diesel technology for Daimler commercial vehicles
BlueTec commercial vehicles have taken to the streets of Europe. highly-efficient BlueTec diesel Mercedes-Benz heavy trucks and Vario vans, Setra buses are all benefiting this technology. the EU4 and EU5, and Euro5 emissions standard are strictly met. This technology merges ecological requirements with economic factors.2 to 5% less diesel fuel is consumed by these vehicles. redesigned engines and a highly effective form of exhaust gas after-treatment form the core of blue tec technology. base engine emissions of soot and particulates have been reduced due to the combustion efficiency improvement. The oxides of nitrogen (NOx) are then converted into harmless nitrogen and water through a catalytic reaction occuring in the gas after-treatment system. This system uses the SCR ( Selective Catalytic Reduction) principle utilizing AdBlue, an aqueous urea solution. Reduction of base emissions was given priority in the process of engine redesign. But reducing the fuel consumption increased the levels of nitrogen oxides.
