Abstract

Ein Abgassystem eines Fahrzeugverbrennungsmotors hat mehrere Abgaskatalysatoren (C¶1¶ bis C¶n¶), die unterschiedliche Arbeitstemperaturbereiche haben. Das Abgas wird abhängig von seiner Temperatur zu dem- oder denjenigen Katalysatoren (C¶1¶ bis C¶n¶) gelenkt, in deren Arbeitstemperaturbereich die Abgastemperatur fällt.
