Title: DEVICE FOR TREATING EXHAUST GASES, EXHAUST LINE AND CORRESPONDING MANUFACTURING METHOD
Abstract:
The device for treating exhaust gases comprises: - at least one purification member (3, 85), with a substrate (11, 87) for purifying exhaust gases; - a heat exchanger (5) axially located beyond an axial end of the substrate (11, 87); - a body (29); - a valve (7) comprising a flap (31) arranged in the internal volume of the body (29). The exchanger inlet (25) and the exchanger outlet (25) open into the internal volume. At least 45% of a volume of the body (29) is in a virtual space (E) located in the axial extension of the one or more purification substrate(s) (11, 87). The body (29) comprises at least one first orifice (39) in fluid communication with the purification member outlet (20), and a second orifice (41) defining an outlet for the exhaust gases.
