Exhaust gas pipe system for a motor vehicle has a wall as a composite component made from multiple adjacent interconnected foil-type layers

摘要

Arranged with clearances in sections, adjacent metal-foil-type layers (38) lie flat close to each other. Lagged for air gaps, an exhaust gas pipe (36) has inner (40) and outer (42) pipes consisting section by section of interlinked foil-type layers. Between these pipes there is an air gap (20).
