Exhaust guide system for internal combustion engine, has sealing element comprising sealing portion, which makes gastight connection with exhaust guide element, where initial tension is provided in sealing element by elastic deformation

摘要

The system (10) has an exhaust guide element (12) comprising a tubular projection with a seal surface rotating in a region of an interface (30) with respect to a geometric axis (24). A sealing system (40) includes a metal mold part as a sealing element, which is applied with a sealing seam at the seal surface of the guide element. An initial tension is provided in the sealing element by elastic deformation and leads to a force on the sealing seam towards the seal surface. The sealing element comprises a sealing portion, which makes a gastight connection with another exhaust guide element (14).
