Exhaust-gas conduction component |
摘要 |
An exhaust-gas conduction component that is effective as a vibration decoupling element and can be installed in an exhaust-gas system for conducting the exhaust gases of a motor vehicle internal combustion engine. The exhaust-gas conduction component (1) has an outer pipe (2) with a corrugated metal tube section (3; 4) and an inner pipe (8) that is coaxial with the outer pipe (2) and separated from the latter by an annular gap. The outer pipe (2) also has a smooth central section (5), first and second corrugated metal tube sections (3; 4) and smooth first and second end sections (6; 7). The inner pipe (8) is permanently fixed to the outer pipe (2) by a continuous joint (9) extending around the central section (5) and the rectilinear exhaust-gas conduction component (1) is approximately axially symmetrical in relation to a central transverse axis (10). The exhaust-gas conduction component is especially suitable in utility vehicles for linking an emission control unit to an internal combustion engine. |
