Definitions

  • the invention relates to an exhaust manifold for exhaust gas discharge from a Internal combustion engine with preferably six cylinders arranged in a row.
  • An exhaust manifold can be used in an in-line engine with more than three cylinders elongated tubular structure to be built, which extends along the row of Exhaust gas outlet openings of the internal combustion engine, wherein on Exhaust manifold opposite each exhaust opening of the internal combustion engine Inlet flange is arranged and at a central portion of the Exhaust manifold a common outlet flange is arranged. Due to the high exhaust gas temperature, the exhaust manifold stretches in its longitudinal extent much stronger than the associated internal combustion engine or cylinder head.
  • the exhaust manifold meets the mechanical loads based on the Withstands thermal expansion, the exhaust manifold must be very robust and therefore thick-walled and heavy, with a relative movement the inlet flanges of the exhaust manifold opposite the outlet openings of the Internal combustion engine must be possible to avoid cracks.
  • cast manifolds are single-walled, composite Exhaust manifolds and double-walled exhaust manifolds, so-called air-gap insulated Exhaust manifold (LSI exhaust manifold) known.
  • LSI exhaust manifold air-gap insulated Exhaust manifold
  • Single-walled and double-walled Exhaust manifolds are usually made of pipes, shells, flanges, etc. welded together.
  • a cast elbow has a thick wall, which is larger than 3 mm due to the manufacturing process which is a high mechanical strength against material overload, based on thermal expansion.
  • the high is a disadvantage Weight of the manifold and also the associated high heat capacity, which, especially in the warm-up phase of the engine, leads to a strong cooling of the Exhaust gas leads.
  • the manifold has a bad one Thermal insulation property, this means energy for the operation of a Exhaust gas turbocharger lost.
  • the light-off temperature becomes one Emission control device and / or the operating temperature of a Exhaust gas cleaning device only reached slowly.
  • Exhaust manifold is lighter than the cast manifold, its mechanical strength against material loads based on thermal expansion, however also less. It also has a welded, single-walled exhaust manifold poor thermal insulation properties and has the same in this regard Disadvantages, such as the manifold.

  • the disadvantage of the multi-part design is the high manufacturing effort and the associated high costs. Furthermore, the multi-part version unfavorable for turbocharged engines because the loader is not so close to Internal combustion engine can be placed, and thus energy loss through the Cooling of the exhaust gases must be accepted.

It is with it possible an air gap-insulated exhaust manifold with a low heat capacity to provide, thereby quickly reaching the operating temperature and thus a quick start of the exhaust gas aftertreatment on cold start can be achieved. Furthermore, the exhaust manifold has a good one Isolation effect, so that the heat losses of the exhaust gas are minimal, resulting in leads to a higher temperature level of the exhaust gases and thus a faster one Start of the exhaust gas aftertreatment on cold start as well as an increased if necessary Enthalpy offer for a possibly connected exhaust gas turbocharger causes. With the advantageous design of the present exhaust manifold, a lighter, heat-insulated exhaust manifold with a long service life available provided that even with a six-cylinder in-line engine, or in one piece can be trained.

  • the web can be made of one material be produced, which has a higher thermal expansion than the material of the remaining components of the exhaust manifold. In this way too Supporting the expansion of the central portion of the exhaust manifold become.
  • the inner shell has the task of removing the exhaust gases from direct the inlet flanges to the common outlet flange.
  • the inner shell is formed from several parts, the parts of the inner shell in areas are connected with great thermal expansion via a sliding seat.
  • the outer shell takes on the supporting function and is gas-tight. This design with sliding seats on the inner shell makes it possible for the Inner shell that is exposed to higher thermal operating voltages than that Outer shell to allow optimal freedom of movement. Furthermore can through this design, the outer shell can be made thinner because the Outer shell not with thermal expansion stresses of the inner shell is applied.
