Claim Text:
1. An assembly for purification of exhaust gases, the assembly comprising: an upstream conduit in which is housed a first unit for purification of exhaust gases; a downstream conduit in which is housed a second unit for purification of exhaust gases, the upstream conduit and the downstream conduit being positioned parallel to each other; a space having an exhaust gas inlet communicating with the upstream conduit and an exhaust gas outlet communicating with the downstream conduit, a middle line dividing said inlet into first and second areas providing respective equal passage sections to the exhaust gases; and wherein the assembly comprises a baffle comprising a first face turned towards the inlet and a second face facing away from the inlet, the baffle being arranged in the space facing the inlet, the baffle in an orthogonal projection on the inlet covering at least 75% of the first area and covering less than 25% of the second area, the baffle and the space being laid out so that a portion of the exhaust gases penetrating through the first area of the inlet flows into the space following flow lines forming a cusp around the baffle, the exhaust gases penetrating through the first area of the inlet, flowing along the first face of the baffle, then flowing in a reverse direction along the second face of the baffle.
