Definitions

  • the invention relates to an exhaust manifold for an exhaust system 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. Set directly on the cylinder head of the internal combustion engine, the exhaust manifold is used 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. Also by the DE 101 02 637 A1 known 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. On the exhaust gas inlet side inlet flanges are provided with inlet openings. At a central portion of the exhaust manifold, the over the Inlet flanges incoming exhaust gases combined on a common outlet flange.
