The term identifies a range of diesel engines and related technologies employed by a prominent German automotive manufacturer to reduce emissions. The system incorporates several components, including particulate filters, oxidation catalysts, and Selective Catalytic Reduction (SCR) systems, utilizing Diesel Exhaust Fluid (DEF) to convert nitrogen oxides into less harmful substances. As an example, a vehicle bearing this designation often exhibits reduced levels of pollutants compared to earlier diesel models.
The significance of these systems lies in their contribution to meeting increasingly stringent environmental regulations. Benefits include improved air quality and a reduction in the environmental impact of diesel-powered vehicles. Its historical context involves the manufacturer’s response to growing concerns about diesel emissions and a proactive approach to developing cleaner vehicle technologies.
