Definitions

  • the invention relates to a device for fastening a suction module to an internal combustion engine according to the preamble of claim 1.
  • a suction module is known from EP 0 448 431 A1, which is operatively connected by means of connection points occurs with a cylinder head or a cylinder head cover.
  • One oil filler neck and one Oil fill pipes are connected to the cylinder head channels for external oil supply.
  • a The screw is spatially supported separately from the oil filler line via an assigned to the suction module Protrusion on a counter surface of the cylinder head.
  • the two executed separately mentioned connection points have an unnecessary multiple fit, increased assembly effort great weight of the suction module, material tension for each screw connection, additional Seals or a complex manufacture or assembly result.
  • the filling line as a support device, an additional one is added to the filling line Support device saved.
  • This has a reduction in manufacturing effort, assembly effort, the component mass and assembly stresses.
  • the number of connection points between the suction module and cylinder head cover become.
  • the support device with the oil filler pipe that is, a hollow, for example annular, cross section is formed.
  • Such cross sections have low mass over a large area moment of inertia, so that lighter and cheaper Execution a great stiffness to avoid vibrations is guaranteed.
  • Advantageous in the embodiment according to the invention 2 is that separate by the one-piece multifunctional part Components can be saved, thereby reducing weight and a reduction in manufacturing costs can be achieved.
  • the support device can, for example made of a temperature-resistant plastic be the for the inlet side temperatures of the Internal combustion engine is suitable.
  • the suction module 2 is formed in one piece and comprises several side by side arranged and with each other via a molded web 5 connected suction pipes 6, at the upper ends 7 a Air collector 8 is attached.
  • the suction module 2 is over the lower one Ends 9 of the intake manifolds 6 on an inlet side 10 of the cylinder head 3 flanged and via a support device 11 the cylinder head cover 4 attached.
  • the suction module 2 extends essentially in the longitudinal direction 12 of the motor over the entire length of the cylinder head 3 and in approximately parallel to the direction of a motor vertical axis 13, the Suction module 2 in its upper region 14a in the direction of the cylinder head cover 4 is slightly curved.
  • the cylinder head cover 4 and the suction module 2 with the air collector 8 and the suction pipes 6 a partial limitation of a free space 15 for installing a Air filter and an exhaust gas turbocharger together with charge air compressor.
  • the motor not shown, is installed in an inclined position.
  • the focus of the suction module 2 is in the direction of the motor vertical axis 13 viewed, approximately laterally above the cylinder head cover 4. Due to the inclined mounting position acts on the suction module 2 a moment which the support device 11 counteracts.
  • the support device 11 for supporting the suction module 2 on the Cylinder head cover 4 is designed as a one-piece multifunctional part, an oil filler pipe 16, an oil filler neck 17, an oil separator 18, one associated with the cylinder head cover 4 first fastening means 19 and one associated with the suction module 2 includes second fastener 20.
  • the first fastener 19 has a mounting flange 21 and that second fastening means 20 comprises two fastening lugs 22a, 22b.
  • the fastening tabs 22a, 22b are on the oil fill line 16 molded in one piece.
  • the multifunction part injection molded which is a simple Even complex parts can be produced.
  • a material serves a temperature-resistant plastic.
  • the oil fill line 16 and the one facing the suction module 2 Page 23 of the oil filling line 16 arranged oil separators 18 are on the mounting flange 21 by means of screws 24 an upper side 25 of the cylinder head cover 4 in an end face 26 facing the cylinder head cover 4 and from a lower one Area 14b of the suction module 2 spaced area 27 attached.
  • the oil filler line 16 which is part of the support device 11 is designed for filling lubricating oil into the Lube oil circuit of the internal combustion engine.
  • the oil fill pipe 16 has at its free end 28a the oil filler neck 17, which can be closed with a lid 29, which has a Top 30 of the air collector 8 protrudes.
  • the oil fill pipe 16 has a kink 31 around an installation space for one not shown part of a charge air line from the air filter to create the charge air compressor of the exhaust gas turbocharger.
  • the suction module 2 Around to avoid strong vibrations of the suction module 2 the two at the upper end 28a of the oil filler line 16 mutually opposite fastening tabs 22a, 22b the suction module 2 on its end face 32 with the oil fill line 16 is connected.
  • a calming volume not shown arranged, which is designed as a channel and through a Opening is connected to the cylinder head 3.
  • the one in the cylinder crankcase existing, oil-containing blow-by gases via a timing chain shaft, not shown, and also Oil return lines, not shown, of the internal combustion engine in the cylinder head 3 and through said opening in the calming volume in the cylinder head cover 4.
  • the oil separator 18 is provided with an oil extraction line 33, which opens into the calming volume in the cylinder head cover 4.
  • the oil separator 18 removes the oil through the line 33 blow-out gases containing oil from the calming volume and separates the oil from the gases.
  • the return of the in the oil separator 18 oil collected in the oil circuit of the internal combustion engine via an oil return line opening out from the oil separator 18 34 with an inlet port, not shown, in the Cylinder head cover 4 is connected. So this is from the oil separator 18 separated oil back into the oil circuit of the internal combustion engine fed.
  • the oil separator 18 can also be provided as a separate component.
  • Suction module 2 also consist of several components.
