Abstract

In der Warmlaufphase wird das Abgasverhältnis von Kraftstoff zu Sauerstoff vor einem Katalysator in Abhängigkeit von der Temperatur des Katalysators eingestellt. Die Kraftstoffmenge wird über die Einspritzzeit bemessen. Die Einspritzzeit berechnet sich aus einer Basiseinspritzzeit, die mit einem Wichtungsfaktor gewichtet wird. Der Wichtungsfaktor hängt von der Sekundärluftmasse, die in den Abgastrakt eingeblasen wird, und einem vorgegebenen Sollwert für das Abgasverhältnis (μ-Wert) von dem Katalysator ab. Die Sekundärluftmasse wird abhängig von der angesaugten Motorluft vorgesteuert.
