Insats i avgaskanal för skapande av turbulent flöde

摘要

An exhaust gas channel insert for generating turbulence and/or for mixing gas flowing through said channel (6; 9), said insert (1) partially covering the cross-sectional area of the exhaust gas channel. The invention is characterised in that the insert (1) includes a helical, elongate wire element where each wire turn (2) in the helix includes angled portions such that each turn will have an essentially star shape; in that the wire element has an extension int eh longitudinal axial direction of the helix along which the wire is unbroken; and in that the wire element is self-supporting.
