Definitions

  • the present invention relates to an air gap-insulated exhaust manifold for an exhaust system of an internal combustion engine, in particular of a motor vehicle, having the features of the preamble of claim 1.
  • an air gap insulated exhaust manifold having a housing having a plurality of inlet openings and a common outlet opening.
  • the outlet port communicates with the inlet openings.
  • the housing consists of an inner shell and a shell surrounding the inner shell to form an insulation gap outer shell.
  • an intermediate shell is arranged in the insulating gap between the inner shell and outer shell, which is supported by spacer elements on the inner shell and on the outer shell.
  • the intermediate shell is in this case assembled from two intermediate shell parts which are inserted into one another in a connection region, wherein in the connection region the one intermediate shell part has an outer end section, while the other intermediate shell part has an inner end section which projects into the respective outer end section.
  • a dividing plane in which the two intermediate shell parts are inserted into one another extends parallel to an exhaust gas main flow direction of the inner shell.
  • the spacer elements are arranged in the known manifold outside the connection region.
  • Such an exhaust manifold is exposed to extreme changes in temperature, so that the dimensions of the individual components can change significantly by heating and cooling relative to each other.
  • deep-drawn projections or embossed beads which serve as spacers, thereby deform plastically, whereby play and distances arise.
  • Vibrations and vibrations during operation of the exhaust system as well as when exposed to pulsating exhaust gas flow can cause unwanted noise.
  • the individual shells can get into vibration, being exposed to an increased risk of damage, especially in the field of natural resonances.
