Summary

For bringing diesel vehicles into compliance with EU6(b) regulation (effective September 2014), a combination of NOx-storage catalyst (NSC) and diesel particulate filter (DPF) is a widespread solution. Upcoming legislation in Europe in general massively extends the operating range in which the emission limits must be adhered to. Since the new legislation aims at reducing Real-Driving-Emissions (RDE), emission limits will not only have to be met in defined cycles on vehicle test beds but also in real driving conditions under various operating conditions. However, high dynamic loads in real driving conditions require high conversion rates (especially of NOx), including areas where NOx-conversion is insufficient with current NSC technologies commonly used for series produced vehicles.
