  • NSC nitrogen storage catalyst
  • Exhaust gas particulate filter A particulate filter DPF mechanically absorbs the soot particles produced during combustion through special filter structures. To ensure the proper function of the particulate filter permanently, the filter must be regenerated regularly. In this case, a regeneration temperature is set, which is several 100K above the prevailing exhaust gas temperature in normal operation. A DPF regeneration phase takes about 5 to 10 minutes.
  • Particulate filters modern vehicles include an emission reduction system that consists essentially of an ECU with an emission management algorithm (EMA) and a number of sensors.
