Mit dieser Methode lassen sich die im Abgas nur teilweise verbrannten oder noch unverbrannten Bestandteile des Kraftstoffs durch hohe Temperaturen nachverbrennen. So wird bei einem Motorbetrieb im fetten Bereich, z. B. in einem Bereich des Luft/Kraftstoffverhältnisses von λ = 0,7–0,9, bei Kaltstart über eine elektrische Sekundärluftpumpe Luftsauerstoff hinter die Auslassventile der Brennkraftmaschine in das Abgas eingeblasen, wo es zur stark exothermen Oxidation der austretenden teiloxidierten Bestandteile des Kraftstoffs kommt. Durch die thermische Nachbehandlung lassen sich zum einen die Schadstoffkonzentrationen im Abgas senken und zum anderen der Zeitpunkt bis zur so genannten light-off-Temperatur des Katalysators durch die bei der Nachverbrennung frei werdenden Wärmeenergie verkürzen.A known type of exhaust aftertreatment in internal combustion engines therein, the exhaust emissions through a thermal aftertreatment to diminish.
