Beschreibung
Zusammenfassung:	The system (56) has an air intake opening for suction of ambient air, an air filter for removing particulate and/or gaseous components from air, and an air discharge opening communicating with a vehicle for introducing air that is treated by the air filter into the vehicle interior. A separation device separates ammonia, and is designed to be activated as required during exceedence of a predetermined threshold for ammonia-concentration in air, where the device is not active in an initial state. The device comprises an ammonia-sensor that produces signal based on the concentration. The selective catalytic reduction (SCR) catalyst system exhibits an ammonia storage system with a storage containing a NH3-storage material, which is selected from a group consisting of ammonia-complex metallic salts e.g. alkali and alkaline earth metallic salts such as Magnesium chloride and ammonia composisition, Calcium chloride and ammonia composisition and Strontium chloride and ammonia composisition, and ammonia-absorbing solids such as activated carbon and zeolite. An independent claim is also included for a vehicle comprising a selective catalytic reduction catalyst system. Die Erfindung betrifft eine Lüftungsanlage (56) zur Luftversorgung eines Fahrzeuginnenraums (64) für ein mit einem SCR-Katalysatorsystem (28) ausgestattetes Fahrzeug (10), wobei die Lüftungsanlage (56) eine Lufteinlassöffnung (60) zur Ansaugung von Umgebungsluft, zumindest einen Luftfilter (68) zur Entfernung von partikulären und/oder gasförmigen Bestandteilen aus der Luft und eine mit dem Fahrzeuginnenraum (64) kommunizierende Luftauslassöffnung (62) zur Einleitung der durch den zumindest einen Luftfilter (68) behandelten Luft in den Fahrzeuginnenraum (64) aufweist sowie ein Fahrzeug (10) mit einem SCR-Katalysatorsystem (28) und mit einer Lüftungsanlage (56) zur Luftversorgung eines Fahrzeuginnenraums (64). Es ist vorgesehen, dass die Lüftungsanlage (56) eine Einrichtung (70) zur Abtrennung von Ammoniak (NH3) aufweist, wobei die Einrichtung (70) eingerichtet ist, bedarfsweise aktiviert zu werden, und in einem Grundzustand nicht aktiv ist.
