Abstract[English]
An aftertreatment unit for an exhaust aftertreatment system includes an aftertreatment housing and a sampling assembly. The aftertreatment housing defines a cavity and an exit opening. The sampling assembly is coupled to the aftertreatment housing. The sampling assembly includes a bowl and a sampler. The bowl is coupled to the aftertreatment housing on a first side of the exit opening. The bowl defines an exhaust aperture configured to provide exhaust into the cavity. The sampler is coupled to the aftertreatment housing at a location on a second side of the exit opening opposite the first side. The sampler includes a sampler tube and a first sampler aperture. The sampler tube is coupled to the bowl, extends into the cavity and across the exit opening, and is configured to provide the exhaust into the bowl. The first sampler aperture is configured to provide the exhaust into the sampler tube.[French]
L'invention concerne une unité de post-traitement pour un système de post-traitement de gaz d'échappement, comprenant un boîtier de post-traitement et un ensemble d'échantillonnage. Le boîtier de post-traitement définit une cavité et une ouverture de sortie. L'ensemble d'échantillonnage est raccordé au boîtier de post-traitement. L'ensemble d'échantillonnage comprend un bol et un échantillonneur. Le bol est raccordé au boîtier de post-traitement sur un premier côté de l'ouverture de sortie. Le bol définit une ouverture d'échappement conçue pour alimenter la cavité en gaz d'échappement. L'échantillonneur est raccordé au boîtier de post-traitement à un emplacement situé sur un second côté de l'ouverture de sortie, opposé au premier côté. L'échantillonneur comprend un tube d'échantillonnage et une première ouverture d'échantillonnage. Le tube d'échantillonnage est raccordé au bol, s'étend dans la cavité et traverse l'ouverture de sortie, et est configuré pour alimenter le bol en gaz d'échappement. La première ouverture d'échantillonnage est configurée pour alimenter en gaz d'échappement le tube d'échantillonnage.
