Exhaust gases after-treatment system for Otto combustion engine of motor car, has exhaust gas cylinders that are dependent on operating point of combustion engine by completely through exhaust gas particulate filter

摘要

#CMT# #/CMT# The system has an exhaust gases device (12) assigned with exhaust gas cylinders (10) through an exhaust gas manifold. The exhaust gases device comprises an exhaust gas particulate filter (14) connected parallel to a catalyst (15). The exhaust gas cylinders are dependent on an operating point of a combustion engine by completely through the exhaust gas particulate filter, partially across the exhaust gas particulate filter or partially guided the catalyst. A check valve is associated with another exhaust manifold depending on the operating point of the combustion engine. #CMT#USE : #/CMT# Exhaust gases after-treatment system for a combustion engine i.e. Otto combustion engine, of a motor car. #CMT#ADVANTAGE : #/CMT# The exhaust gas cylinders are dependent on the operating point of the combustion engine by completely through the exhaust gas particulate filter, partially across the exhaust gas particulate filter or partially guided the catalyst, thus reducing exhaust gas particle emission. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an exhaust gases after-treatment system for a combustion engine of a motor car. 10 : Exhaust gas cylinders 11 : Cylinder group 12 : Exhaust gases device 14 : Exhaust gas particulate filter 15 : Catalyst.
