Exhaust gas purification device for cleaning exhaust gas flow of combustion engine of motor vehicle, has exhaust gas guide unit with catalytic unit, and storage unit arranged in direct heat transfer contact and adjacent to catalytic unit

摘要

#CMT# #/CMT# The exhaust gas purification device (1) has a storage unit (7), by which a reducing agent (9) for selective catalytic reduction is stored. A heating unit (11) is provided for heating the storage unit. An exhaust gas guide unit (13) is provided for guiding the exhaust gas flow (3). The entire exhaust gas flow is directly bypassed to the storage unit by the exhaust gas guide unit. The exhaust gas guide unit comprises a catalytic unit (15) designed for carrying out selective catalytic reduction. The storage unit is arranged in direct heat transfer contact and adjacent to the catalytic unit. #CMT# : #/CMT# Independent claims are included for the following: (1) a method for operating an exhaust gas purification device; and (2) a motor vehicle with an exhaust gas purification device and a software designed for operating an exhaust gas purification device. #CMT#USE : #/CMT# Exhaust gas purification device for cleaning an exhaust gas flow of a combustion engine of a motor vehicle (Claimed) by selective catalytic reduction. #CMT#ADVANTAGE : #/CMT# The entire exhaust gas flow is directly bypassed to the storage unit by the exhaust gas guide unit, where the exhaust gas guide unit comprises a catalytic unit designed for carrying out the selective catalytic reduction, and the storage unit is arranged in a direct heat transfer contact and adjacent to the catalytic unit, and thus enables a simple and compact structure of the exhaust gas purification device, and ensures quick and efficient cleaning of the exhaust gas flow without circulation of an auxiliary heat conveying medium. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an exhaust gas purification device. 1 : Exhaust gas purification device 3 : Exhaust gas flow 5 : Combustion engine 7 : Storage unit 9 : Reducing agent 11 : Heating unit 13 : Exhaust gas guide unit 15 : Catalytic unit.
