BLUETEC WAVE

[Abdul]

BLUETEC® is a modular emissions control system that reduces nitrogen oxides in particular. These are exhaust components from diesel engines, which, as a result of the constraints inherent in the diesel combustion process, exceed the levels generated by petrol engines. Mercedes-Benz has developed two versions of BLUETEC®. In the E Class, an oxidation-type catalytic converter and particulate filter are combined with an improved, extremely durable NOx storage catalytic converter and an additional SCR catalytic converter. The second BLUETEC® version is even more efficient: AdBlue, an aqueous urea solution, is injected into the exhaust gas flow, a process that releases ammonia, which converts up to 80 per cent of the nitrogen oxides into harmless nitrogen and water in the downstream SCR unit.

Available at last in USA: low-sulphur diesel fuel

In order to be completely effective, BLUETEC® technology for passenger cars and light trucks requires low-sulphur diesel with a sulphur content of less than 15 ppm. This clean fuel, which became available in USA in the autumn of 2006, also reduces the emissions from all diesel engines currently on the market and therefore plays a key role in cutting emission levels in general.

BLUETEC® technology was subjected to a particularly challenging endurance test in the autumn of 2006 when a total of 33 E Class models, including three E 320 BLUETEC vehicles, drove from Paris to Beijing in 26 days. In an impressive demonstration of the robustness and quality of this technology, the vehicles performed outstandingly well under extreme conditions on the 13,600 km trip.

Recognition for BLUETEC®

Die BLUETEC has met with an extremely positive response in USA: respected American science and technology magazines recognised the Mercedes-Benz-developed BLUETEC® technology at the end of 2006. Scientific American selected BLUETEC as one of the top 50 scientific and technological innovations of 2006. Popular Science, the oldest and best-known American science magazine included BLUETEC in its annual "Best of What's New" list. And Ward's Automotive Group, a leading publisher of a number of media and trade magazines for the automotive industry, has nominated the E 320 BLUETEC engine for its list of ten best drive systems in 2007.
