#CMT# #/CMT# The method involves oxidizing carbon compound present in an exhaust gas flow in a catalytic manner and forming ammonia from components of the exhaust gas flow in a diesel oxidation catalyzer (14) in a catalytic manner. Particles present in the exhaust gas flow are filtered, and the formed ammonia is stored in combined component (16). A nitrogen oxide compound present in the exhaust gas flow is reduced in the combined component under application of the stored ammonia as reducing agents. An internal combustion engine is operated in an operating phase. #CMT# : #/CMT# Independent claims are also included for the following: (1) a device for post-treatment of exhaust gases of combustion engine of a motor vehicle, comprising a diesel oxidation catalyzer (2) a motor vehicle comprising a control device. #CMT#USE : #/CMT# Method for post-treatment of exhaust gas of an internal combustion engine i.e. diesel engine, of a motor vehicle (all claimed) for reducing a portion of nitrogen oxide in an exhaust gas flow of the engine. #CMT#ADVANTAGE : #/CMT# The method reduces external supply of ammonia, and nitrogen oxide emissions in the exhaust gas flow of the diesel engine of the motor vehicle, thus lowering unwanted exhaust gas components in the internal combustion engine in an easy and effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a device for post-treatment of exhaust gases of an internal combustion engine of a motor vehicle.'(Drawing includes non-English language text)' 10 : Diesel engine 14 : Diesel oxidation catalyzer 16 : Combined component 20 : Diesel particulate filters 24 : Exhaust section. |
