Vehicle, particularly motor vehicle, has exhaust system, which has catalyst system operating according to principle of selective catalytic reduction with selective catalytic reduction-catalyst arranged in exhaust channel of exhaust system

The vehicle has an exhaust system (14), which has a catalyst system (20) with a selective catalytic reduction-catalyst (22) and has an ammonia storage system (24). The ammonia storage system has a storage, which is formed as a replacement cartridge (26) replaceable by a user of the vehicle. The ammonia-storage material of the replacement cartridge is selected from ammonia-complexed metal salts, particularly alkali, alkaline earth and transition metal salts, and ammonia adsorbing solids, particularly activated carbon and zeolite. Die Erfindung betrifft ein Fahrzeug (10) mit einer Abgasanlage (14), die ein nach dem Prinzip der selektiven katalytischen Reduktion (SCR) arbeitendes Katalysatorsystem (20) mit zumindest einem in einem Abgaskanal (16) der Abgasanlage (14) angeordneten SCR-Katalysator (22) und mit einem Ammoniakspeichersystem (24) aufweist, wobei das Ammoniakspeichersystem (24) zumindest einen Speicher (26, 54, 60) umfasst, der ein NH3-Speichermaterial enthält, das temperaturabhängig Ammoniak (NH3) freizusetzen vermag.
