Air gap insulated exhaust manifold

摘要

The manifold has an inside pipe (11) mounted on an outside pipe (10) only in an attachment area (15) which is arranged with respect to a longitudinal direction (3) approximately centrally between an outlet opening (4) and an inlet opening (5) which is at the greatest distance from the outlet opening. A flange (6) extends in the longitudinal direction. A collecting line (2) extends in a longitudinal direction (3). The outlet opening is oriented in the longitudinal direction. Multiple inlet openings are formed along the longitudinal direction.
