Definitions

  • the invention relates to a holder of an exhaust gas recirculation line on the motor housing of an internal combustion engine according to Preamble of claim 1.
  • DE 35 29 543 C2 is already a generic bracket an exhaust gas recirculation line on the engine housing of an internal combustion engine known, the exhaust gas recirculation line from a branches off the exhaust pipe near the engine and with an intake pipe Internal combustion engine is connected. Via an additional engine-fixed The support is the exhaust gas recirculation line along with the exhaust gas recirculation valve held on the cylinder head of the internal combustion engine.
  • the invention has for its object a compact bracket to create which with optimal use of the existing Space is easy and inexpensive to manufacture, as well as a time and cost saving installation.
  • An advantage of the holder according to the invention is that by integrating the support into part of the exhaust gas recirculation line the bracket can be manufactured in a very compact design is.
  • the saving of a separate support also enables a reduction in manufacturing costs while reducing weight the bracket and a reduction in assembly effort.
  • the component is not only used to hold the Exhaust gas recirculation line on the engine housing of the internal combustion engine, but also the support of the mixing housing and the Suction module.
  • the component By attaching the component to the cylinder head cover and both on the mixing housing Bracket of the exhaust gas recirculation line as well as the support of the Suction module and the mixing housing on the engine housing of the internal combustion engine.
  • the component also enables a reduction the assembly effort, since only one support is to be installed is.
  • In a particularly advantageous construction of the Invention has the component axially extending stiffening ribs which counteract the forces acting on the component.
  • a preferred embodiment of the invention provides that the Mounting on the cylinder head cover using the anyway for the Fastening the cylinder head cover to the cylinder head of the internal combustion engine required fastening screws.
  • the exhaust gas recirculation line 1 is formed in two parts and includes a first line part 5, which is by means of a pipe clamp 6 is sealingly connected to a second line part 7.
  • a first line part 5 of the exhaust gas recirculation line 1 branches from one Exhaust pipe 8 close to the engine, which in a collecting space 9 a Exhaust manifold 10 opens, which via exhaust pipes 11 at a Exhaust side 3a of the cylinder head 3 of the internal combustion engine is flanged.
  • That connecting to the first line part 5 second line part 7 is connected via a flange connection 12 a mixing housing 13 in connection, which in turn with a Intake line 14 of the internal combustion engine is connected.
  • the suction line 14 is part of a on an inlet side 3b of the cylinder head 3 flanged intake module 15.
  • Das Suction module 15 extends in the direction of an engine longitudinal axis 23 essentially over the entire length of the cylinder head 3 and approximately parallel to the direction of a motor vertical axis 24.
  • the mixing housing 13 has a first, via an upper side 15a of the suction module 15 protruding vacuum box 16, the one Exhaust gas recirculation valve arranged in the mixing housing 13 controls.
  • the mixing housing 13 has connections 17 for connecting one second vacuum box, not shown here, which a throttle valve also arranged in the mixing housing 13 controls.
  • the exhaust gas recirculation line 1 is in its course over a engine-fixed support 18 held on the internal combustion engine, wherein according to the invention, the second line part 7 of the exhaust gas recirculation line 1 with the support 18 to form a component 19 is.
  • the component 19 is preferably formed by a cast part and has axially extending stiffening ribs 22. In the area of the support 18, the component 19 has one piece molded mounting flange 20 and is over this Flange 20 using fastening screws 21 on the cylinder head cover 4 attached to the internal combustion engine.
  • the motor which is only partially shown, is installed in an inclined position, whereby the focus of the suction module 15 in the direction the engine vertical axis 24 viewed, approximately laterally above the cylinder head cover 4 lies. Due to the inclined position of the Motors acts on the suction module 15 together with the mixing housing 13 for a moment, which counteracts the holder connected to the suction module 15.
  • the component 19 forming the holder thus serves not only for exhaust gas recirculation, but also at the same time Supporting the mixing housing 13 and the suction module 15.
  • the fastening screws 21 for fastening the bracket or the component 19 on the cylinder head cover 4 at the same time for attaching the cylinder head cover 4 to the cylinder head 3 Serve internal combustion engine so that separate screws are omitted can.
