Summary

Description
English: regeneration process of a diesel particulate filter without additive in a Volkswagen 2008 1.9 TDI with pump-injectors

Legend:

  • Red: additional diesel injection mass
  • Green: filter load
  • Salmon: exhaust gas temperature before filter
  • Blue: exhaust gas temperature after filter
  • Brown: exhaust gas temperature before turbocharger

Stages:

  1. Start of the regeneration by igniting the carbon inside the filter with heated exhaust gas via additional diesel injection after the main combustion
  2. Ignition of the exothermic burning inside the filter slightly less additional fuel is injected
  3. Deceleration fuel cutoff resulting in increase of oxygen in the exhaust gas resulting in faster and hotter burning
  4. Additional fuel injection is cutoff and the remaining ignited carbon-particulate matter burns away
Deutsch: Regenerationsprozess eines additiv-losen Dieselpartikelfilters in einem 2008er 1.9L Volkswagen TDI mit Pumpe-Düse-Einspritzung

Legende: Rot: zusätzliche Diesel-Einspritzmenge Grün: Filterbeladung Hautfarben: Abgastemperatur vorm Filter Türkis: Abgastemperatur hinterm Filter Braun: Abgastemperatur vorm Turbolader

Stufen der Regeneration:

  1. Einleitung der Regeneration durch Anhebung der Abgastemperatur mithilfe von zusätzlichem, nach der Hauptverbrennung, eingespritztem Dieselkraftstoff
  2. Zündung der exothermen Partikelverbrennung durch Rücknahme der zusätzlichen Einspritzmenge
  3. Verzögerung (Motorschlepp) führt zu einer schnelleren Verbrennung im Filter, da sich der Sauerstoffanteil im Abgas erhöht
  4. es wird keine Zusätzlicher Kraftstoff mehr eingespritzt und die Verbrennung schreitet bis zum Erlöschen fort
