57	Abstract	AB	Die Erfindung betrifft ein Kraftfahrzeug mit einer Brennkraftmaschine und einer Abgasnachbehandlungseinrichtung sowie ein Verfahren zur Partikel- und Stickoxidverminderung.$A Die Abgasnachbehandlungseinrichtung umfasst einen Partikelfilter (4) sowie einen NOx-Adsorber (5) und einen in Abgasströmungsrichtung dem NOx-Adsorber (5) nachgeschalteten SCR-Katalysator (6), wobei der NOx-Adsorber (5) zumindest unterhalb einer vorgegebenen Desorptionstemperatur (T↓D↓) aus ihm zugeführten oxidierenden Abgas NOx durch Einspeicherung entfernen und bei Überschreiten der Desorptionstemperatur (T↓D↓) gespeichertes NOx thermisch desorbieren und an das Abgas abgegeben werden kann.$A Erfindungsgemäß sind die Desorptionstemperatur (T↓D↓), die Anspringtemperatur (T↓LO↓) des SCR-Katalysators (6) und die Anordnung des NOx-Adsorbers (5) und des SCR-Katalysators (6) derart gewählt, dass ausgehend von einem Zustand der Abgasnachbehandlungseinrichtung, bei welcher der NOx-Adsorber (5) eine Temperatur unterhalb der Desorptionstemperatur (T↓D↓) und der SCR-Katalysator 6 eine Temperatur unterhalb der Anspringtemperatur (T↓LO↓) aufweisen, bei einer Aufheizung der Abgasnachbehandlungseinrichtung durch Zufuhr von erhitztem Abgas zum NOx-Adsorber (5) der SCR-Katalysator (6) die Anspringtemperatur (T↓LO↓) zu einem früheren Zeitpunkt erreicht als der NOx-Adsorber (5) die Desorptionstemperatur (T↓D↓).
