That was a compromise the Germans made with the wonks at CARB that set the emissions standards for the whole country. The EPA are just yes men to California Air Resources Board. I believe all the vehicles stuck with that goofy system get free refills for the period of the warranty. If I were to buy a Diesel Mercedes, I would get a used one prior to the blutec engine. Our tax dollars have paid to develop a much better system and it is only being used in other countries.

Replying to: agrawal (Oct 19, 2009 6:04 pm)  Urea plays an important role in the metabolism of nitrogen-containing compounds by animals, and is the main nitrogen-containing substance in the urine of mammals.wiki Seems that I read it is about 20% Urea in a water base. The BlueTec system, for example, injects water-based urea solution into the exhaust system. The ammonia produced by decomposition of the urea reacts with the nitrogen oxide emissions and is converted into nitrogen and water within the catalytic converter.

Replying to: gagrice (Oct 19, 2009 6:34 pm) Mazda’s latest four-wheel-drive likes a wee drink. The Mazda CX-7 uses a special man-made liquid similar to human urine to reduce emissions of oxides of nitrogen (NOx). The compound, called AdBlue, is a mixture of roughly one-third pure urea and two-thirds demineralised water. It is already widely used in the trucking industry in Europe and Australia and is common in diesel cars in Europe, but Mazda is the first to use the technology on a passenger vehicle in Australia. The technology, called selective catalyst reduction, involves injecting the urea-based liquid into the car’s exhaust system to turn NOx emissions into harmless nitrogen and water. http://www.theage.com.au/drive/motor-news/the-car-that-uses-urine-to-save-the-pl- anet-20091014-gwiy.html |

What Would It Take for YOU to buy a diesel car? Mercedes GLK220CDI or C220CDI BMW X3 2.0d or 320d Best next thing is VW, they have the 4cylinder diesel market cornered with the Golf and Jetta.

Replying to: mark_c (Oct 22, 2009 5:19 am) Apparently they have decided they need to sell 10K per year to break even on the investment necessary to make their diesel emissions-compliant. But they have another problem, similar to the one Honda had: currently their global diesel is manual-trans-only, and of course they have to have an automatic available for the soft Americans, or they will never hit their sales targets.... Since Mazda and VW sales are on the same order of magnitude, it seems like Mazda could probably sell small diesel models profitably here, since VW seems to be able to. But in their home market, there is a lot of pressure to be offering three kinds of hybrids and all-electrics as well, so their diesel program wouldn't serve them that well at home. |
