Abstract

In einem Anfangszustand wird die Abgastemperatur an einem Katalysatoreinlass, basierend auf einer gespeicherten Abgastemperatur des vorherigen Abschaltens des Motors und einer abgelaufenen Zeit zwischen dem vorherigen Abschalten des Motors und dem folgenden erneuten Starten des Motors, vorhergesagt. In einem Dauerzustand wird die Abgastemperatur am Katalysatoreinlass durch Summieren der Basis-Abgastemperatur am Katalysatoreinlass und der Auspuffrohrtemperatur am Katalysatoreinlass mit einer vorbestimmten Rate vorhergesagt.
