Abstract
The assembly for purification of exhaust gases comprises an upstream conduit and a downstream conduit positioned parallel to each other. A space has an exhaust gas inlet communicating with the upstream conduit and an exhaust gas outlet communicating with the downstream conduit. A middle line divides the inlet into first and second areas providing a same passage section to the exhaust gases. The assembly comprises a baffle covering at least 75% of the first area and covering less than 25% of the second area. The baffle and the space are laid out so that a portion of the exhaust gases penetrate through the first area of the inlet flows into the space along flow lines forming a cusp around the baffle.
Claims15
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 a same passage section to the exhaust gases;
- and
- a baffle 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.
