Arrangement with exhaust system for internal combustion engine

摘要

A tubular part (2) connects to the terminating outer part of the exhaust pipe (1) and is joined to a screw spring-shaped part (3) extending from its free end part. A plate-shaped part (4) forms an outer limiting plane. The plate-shaped part has one or more through holes or recesses. By manual activation, the spiral spring-shaped part free length extend can be shortened or extended to reduce or increase the outlet area from the exhaust system located between adjacent windings in the screw spring-shaped part. The screw spring-shaped part is formed from a strip material with a rectangular cross-section, and with inner and outer limiting surfaces forming the narrower size surfaces.
