Definitions

  • the invention relates to an exhaust manifold for attachment to a cylinder head of an internal combustion engine according to the features in the preamble of claim 1.
  • An exhaust manifold is a component of an exhaust system of internal combustion engines, in particular of internal combustion engines in motor vehicles. Attached directly to the cylinder head of the internal combustion engine, the exhaust manifold serves to merge the exiting from the individual cylinders exhaust and forward an exhaust gas outlet. An exhaust manifold is therefore often referred to as exhaust manifold.
  • An air gap insulated exhaust manifold counts by the US 5,729,975 A to the state of the art. This has an inner tube system and a surrounding the inner tube system at a distance outer shell and an inlet flange and an outlet flange.
  • the DE 101 02 637 A1 an exhaust manifold to Exhaust system.
  • the exhaust manifold has an inner tube system, there formed as an inner shell, which is surrounded by an outer shell, so that between the inner shell and the outer shell, an air gap is formed.
  • the exhaust gases flowing in via the inlet flanges are brought together on a common outlet flange.
  • an air gap insulated exhaust manifold which consists essentially of three components: an outer shell, an inner shell and a fixable on the cylinder head of the engine flange.
  • the outer shell and the inner shell are each hood-shaped and each have a circumferential collar, wherein the outer shell collar is connected to the flange and the inner shell collar is clamped between outer shell collar and flange.
  • a plurality of knob-shaped or wave-shaped bulges are formed on the inner shell collar, which are punctiform supported against the outer shell collar and / or the flange.
