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. |
