Definitions

  • the invention relates to an intake module for an internal combustion engine according to the preamble of the main claim.
  • the conventional manufacturing processes for molding three-dimensional pipe structures made of plastic are for example a so-called lost-core process or the prefabrication of half-shells after assembly overmolded with plastic again.
  • a core e.g. made of a tin / bismuth alloy
  • This Core is overmolded with the plastic and then melted out so that the hollow tube remains.
  • This known method is disadvantageous because of the pressure-resistant core material high demands are made and the manufacturing process is very complex and time-consuming is.
  • the prefabrication of half shells as another manufacturing option causes relatively high tool costs and is also disadvantageous in that the necessary tight connection of the two half shells or additional flanges makes further manufacturing steps necessary.
  • DE-A-2 457 155 discloses an intake module with an air intake pipe made of plastic and a flange connection for Air inlet known to a cylinder head housing.
  • the air intake pipe lies in a housing part of the intake module the air outlet of the air intake pipe in a connection area of the housing part led to the cylinder head housing and is located at the connection area of the housing part there is a flange integral with the housing part with which the housing part seals against the air inlet of the cylinder head housing is attachable.
  • a disadvantage of this intake module is the complex manufacturing process of the air intake pipe and the process reliability when connecting the Air intake pipe with the housing.
  • thermoplastic To design material using the blowing process.
  • a special one Design of intake modules is this state of the art not to be removed.
  • the invention has for its object a suction module for an internal combustion engine according to the preamble of the main claim in a simple way so that a simple Manufacturing is possible and thus a well-sealed Suction device can be built.
  • the suction module according to the invention solves the task with the characteristics specified in the label of the main claim.
  • This suction module according to the invention is advantageous in that by using a plastic blow molded part a simple manufacturing process as an air intake pipe also applicable for more complex three-dimensional pipe structures is.
  • the necessary tight connection of the intake pipe to the cylinder head housing of the internal combustion engine in advantageously ensured that the housing tightly attached to the suction device via a splash is, the suction pipe is held in the housing and itself no tight connection to the cylinder head housing needed.
  • the suction module is assembled in a simple manner by fastening the intake pipe, for example by means of a leaf or clamp spring in at least one of the Half-shells of the housing, by joining them tightly together the half shells of the housing and the subsequent assembly of the flange of the intake module housing on the cylinder head housing of the internal combustion engine.
  • the housing of the intake module is advantageously made of very temperature-tested glass fiber reinforced polyamide and the intake pipe made as a blowpipe made of polyamide.
  • the flexible attachment of the intake pipe enables simple Way the optimal selection of an intake pipe regarding the geometric design and in particular the Use of a suction pipe with an adapted length in the largely unchanged housing.
  • FIG. 1 In the figure is a section through a housing 1 of an intake module for one here, except for a mounting surface on Cylinder head housing 2, internal combustion engine, not shown shown a motor vehicle.
  • Through the intake module becomes an air flow according to arrow 3 towards the inlet openings sucked into the cylinder head housing 2.
  • the raw air in the inlet 4 of the intake module through an air filter 5 led into the clean room area 6 of the intake module.
  • the air intake pipe 8 In the lower housing part 7 of the housing 1 there is an air intake pipe 8 inserted, completely as a blowpipe made of polyamide is made.
  • the length of the suction pipe 8 can also be adapted to the conditions of the internal combustion engine and, for example, also include an extension 8 '.
  • the air intake pipe 8 is, for example, via a Leaf or clamp spring 9 held on the lower housing part 7.
  • the air outlet area of the lower housing part 7 is formed as a flange 10 which has one end 11 of the inside Air intake pipe 8 receives and outside on the cylinder head housing 2 is attachable.
  • a seal 12 available by means of a fastening device 13 the cylinder head 2 is pressed.
  • the air drawn in can thus come from the clean room area 6 via a clean air outlet 15 to a not shown here Throttle valve and then via a clean air inlet 14 in that, particularly with regard to Sound emission spatially optimized, air intake pipe 8 and then go directly into the inlet on cylinder head 2.
  • a sealing attachment is only between the flange 10 made of very resilient and temperature-resistant material Housing part 7 and the possibly quite high temperatures generating cylinder head housing 2 necessary, a tight Arrangement between the air intake pipe 8 made of polyamide and the cylinder head housing 2 is not required here.
  • a seal between the air intake pipe 8 and the lower one Housing part 7 is not critical as a possible Secondary air is only drawn in from the clean room area 6.
