BlueTec Project to Combat ObNOxious Greenhouse Gas

BlueTec is a joint project between Volkswagen,Audi, and Daimler-Chrysler, and is designed to establish the diesel engine further as the clean,low-consumption alternative in the American car market. And Volkswagen have demonstrated that a normal diesel fitted with a nitrogen oxide reservoir catalytic converter can substantially reduce emissions of nitrogen oxide.


Nitrogen oxide (NOx) is not often mentioned as an unwanted gas emission . Whereas, carbon dioxide is scarcely out of the news. It may seem strong to label NOx ,a colourless trace gas with a pleasantly sweetish odour and taste (as defined in the Britannia Concise Encyclopaedia), an unpleasant greenhouse gas.But when mixed in a cocktail with other greenhouse gases in the atmosphere, it may aggravate conditions tending to intensify the phenomenon of global warming leading to climate change. Not so good,then!

The catalytic converter being used in the Jetta with a 2.0 litre common rail diesel engine absorbs the NOx like a sponge. The engine runs more efficiently,too. The system is also regularly cleaned during normal motoring without the driver being aware.

This 'clean' engine when it goes into production during 2008 in the US will meet NOx emission requirements considered to be the most stringent worldwide,with up to 90 % less emissions.
