The invention relates to the construction of engines and, more precisely, the exhaust arrangements for internal combustion engines. The arrangement contains an exhaust pipe (1) and at least one connection piece (4), which is connected to the latter and has a passage (5) with an inlet cross-section (6) and an outlet cross-section (7), the inlet cross-section (6) and the outlet cross-section (7) being situated on both sides of the axis (9) of the exhaust pipe (1). The angle (10) between the rectifying plane (11) which extends via the first tangent (14) to the axis (12) of the passage (5) of the connection piece (4) at the intersection of the axis (12) of the passage (5) with its outlet cross-section (7), perpendicularly to the principal normal (15) of the axis (12) of the passage (5) at the same intersection (13), and the second tangent (16) to the axis (9) of the exhaust pipe (1) at the intersection (17) of the rectifying plane (11) with the axis (9) of the exhaust pipe (1) is 20-45 DEG . The angle between the osculating plane extending via the said first tangent (14) and the said principal normal (15) and the third tangent to the axis (9) of the exhaust pipe (1) at the intersection of the said osculating plane with the axis (9) of the exhaust pipe (1) is 1-22 DEG . <IMAGE> |
