Elbow assembly for post-treatment of the exhaust gases of a combustion engine comprising an internal diffuser

摘要

#CMT# #/CMT# The assembly has a selective catalytic reduction (SCR) reducer introduction unit (5) with an opening located in a bend (3) of a casing. A converging portion (8) is provided inside a housing (1) between an oxidation catalyst (2) and the bend, and emerges opposite to the opening of the introduction unit. The converging portion covers the entire cross section of the casing such that gas flow penetrates the converging portion. The converging portion includes walls partially perforated by orifices. The converging portion is welded into the housing. #CMT#USE : #/CMT# Assembly for post-treatment of exhaust gases of an internal combustion engine of a vehicle i.e. car. #CMT#ADVANTAGE : #/CMT# The converging portion is provided inside the housing between the oxidation catalyst and the bend, and emerges opposite to the opening of the introduction unit, thus enabling post-treatment of exhaust gases of an internal combustion engine in a cost-effective manner. The assembly is manufactured with light-weight. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an assembly for post-treatment of exhaust gases of an internal combustion engine. 1 : Housing 2 : Oxidation catalyst 3 : Bend 5 : SCR reducer introduction unit 8 : Converging portion.
