BlueTec is DaimlerChrysler's name for its two nitrogen oxide (NO_x) reducing systems, for use in their Diesel automobile engines. One is a urea based reductant called AdBlue, the other is called DeNO_x and uses an oxidising catalytic converter and particulate filter combined with other NO_x reducing systems. Both systems were designed to slash emissions further than ever before. Mercedes-Benz introduced the systems in the E-Class (using the 'DeNO_x' 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. DaimlerChrysler has entered an into agreement with Volkswagen and Audi to share BlueTec technology with them. Together they try to push diesel technology to the masses in the United States. DaimlerChrysler AG (ISIN: DE0007100000) headquartered in Stuttgart, Baden-Württemberg, Germany, Auburn Hills, Michigan, USA and Japan is a prominent automobile and truck manufacturer and financial services provider (through DaimlerChrysler Financial Services). ... The term nitrogen oxide is a general term and can be used to refer to any of these oxides (oxygen compounds) of nitrogen, or to a mixture of them: Nitric oxide (NO), nitrogen(II) oxide Nitrogen dioxide (NO2) Dinitrogen monoxide (N2O) (Nitrous oxide) Dinitrogen trioxide (N2O3) Dinitrogen tetroxide (N2O4) Dinitrogen...

The BlueTec system was created because the processes that give diesel engines efficient fuel economy also create extra emissions. High compression ratios and lean air-fuel mixtures make high combustion temperatures, which results in more nitrogen oxides and Diesel Particulate Matter (also known as smoke) being released into the atmosphere. While the particulate matter can be controlled with higher injection pressures and particulate filters, the big challenge is limiting NO_x (Tier 2 regulations in the US are 0.05 gram per mile of NO_x, which is ⅛ of the 0.40 limit in the European Union). Bold text The compression ratio is a single number that can be used to predict the performance of any engine (such as an internal-combustion engine or a Stirling Engine). ... Diesel particulate matter (DPM) refers to the particulate components of diesel exhaust, which include diesel soot and aerosols such as ash particulates, metallic abrasion particles, sulfates, and silicates. ...

The Bluetec system will use two catalytic converters specifically targeting NO_x. The first converter traps the NO_x, and later releases it to the second converter which then converts it to nitrogen (N₂) and water (H₂O). This will make a diesel car legal in 45 states. But to make it pass the more stringent regulations of California, Maine, Massachusetts, New York and Vermont, AdBlue (NH₄) will have to be introduced into the system, making the conversion more complete.

The whole exhaust system would work like so:

1. A Diesel oxidation catalyst reduces carbon monoxide (CO) and hydrocarbons (HC) released from the exhaust.
2. A DeNO_x catalytic converter begins a preliminary removal of oxides of nitrogen.
3. A particulate filter will trap and store smoke particles, burning them off when the filter gets full.
4. A Selective Catalytic Reduction (SCR) catalytic converter will take the remaining nitrogen oxides and covert them to nitrogen and water. AdBlue will be injected into it to help the conversion.
