The line (2) has a joint (7) interposed between a depollution system (3) and an exhaust conduit (8). The joint consists of two surfaces (S1, S2) respectively managed along planes (P1, P2), which are connected together to form an angle (A) strictly ranging between 90 and 180 degrees. One of the surfaces is arranged in a conical portion (9), where the conical portion and a cylindrical portion are provided in same revolution axis (A1). The joint is equipped with a ring (11) with a cylindrical part (12) and a conical part (13).

Exhaust line for internal combustion engine e.g. diesel engine, of motor vehicle, has joint consisting of two surfaces managed along planes, which are connected together to form angle strictly ranging between specific values

The line has a particle filter (4) contained in a metallic envelope (5) and an outlet bell mouth (6) placed between an outlet of the filter and an inlet of an exhaust pipe (7). The bell mouth includes a heat exchanger to decrease heat energy of gas stream issued from the filter and canalized through the bell mouth towards the inlet of the exhaust pipe. The exchanger accelerates the exhaust speed of the gas stream from the filter. The exchanger includes blades (8) placed according to a generatrix of the bell mouth and fixed on an outer surface of the bell mouth.
