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

摘要

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).
