Combustion process and exhaust gas aftertreatment in the Mercedes-Benz Bluetec concept

In recent years, Mercedes-Benz has frequently reached important emission control milestones in diesel engines: In 1985, the world’s first serial production particulate filter for passenger cars, in 2003 the first modern particulate filter with additive-free regeneration, and, in October 2006, the United States market launch of the E 320 Bluetec. This vehicle is the first serial production diesel passenger car to exceed the requirements of U.S. Tier II Bin 8 standards. The Bluetec concept is based on several building blocks: the base engine with significantly reduced engine out emissions, the oxidation catalyst and particulate filter, the nitrous oxide aftertreatment, and the associated system control.In recent years, Mercedes-Benz has frequently reached important emission control milestones in diesel engines: In 1985, the world’s first serial production particulate filter for passenger cars, in 2003 the first modern particulate filter with additive-free regeneration, and, in October 2006, the United States market launch of the E 320 Bluetec.

Bluetec — Das Konzept für Dieselmotoren mit niedrigsten Emissionen

Im Oktober 2006 hat Mercedes-Benz mit der Markteinfuhrung des E-Klasse-Modells E 320 Bluetec in den USA den ersten Serien-Pkw mit Dieselmotor auf den Markt gebracht, der die US-Tier-2-Bin8-Abgasgrenzwerte erreicht hat. Noch im Jahr 2008 wird Mercedes-Benz die „Bluetec“-Offensive fortfuhren und den V6-Dieselmotor in der M-, GL- und R-Klasse in den USA mit SCR-/AdBlue-Technik anbieten. Damit werden diese Fahrzeuge die US-Tier-2-Bin5-Grenzwerte und damit alle derzeit weltweit gultigen Abgasvorschriften fur Diesel-Pkw unterschreiten.

Bluetec — The concept for diesel engines with lowest emissions

In October 2006 when Mercedes-Benz introduced the model E 320 Bluetec, it brought the first production diesel passenger car to the market that met US Tier 2 Bin8 emission standards. Mercedes-Benz will continue its Bluetec offensive in 2008, offering the V6 diesel engine in the M, GL and R Classes in the USA, using the SCR/AdBlue technology which meets the US Tier 2 Bin5 emission standards and thereby all currently valid emission standards for diesel passenger cars worldwide.

Diesel engines for the new E-Class

Following the 1997 launch of the first common rail 4-cylinder diesel engine in the C-Class, Mercedes-Benz added the 5- and 6-cylinder engines to the engine range in 1999. For the vehicles of the new E-Class, the 4-, 5- and 6-cylinder engines underwent extensive technical overhauling. With identical displacement, improved common rail injection and measures for reducing friction, these engines will also occupy a leading position among competitors of the new E-Class with respect to driving pleasure, fuel economy and comfort.
