Definitions

  • the invention relates to an intake system for an internal combustion engine according to the preamble of claim 1.
  • each intake pipe is made up of three parts, a first intake manifold part on the cylinder head side and a second intake pipe part, which is connected to the air collector is, are each longitudinally divided and by a middle one The intake manifold part can be complemented.
  • This middle one The intake manifold part is interchangeable, with one change the intake manifold geometry of this part different overall lengths of the suction pipe can be adjusted. hereby is an intake manifold length adjustment with relatively simple measures while maintaining the air collector geometry to different Internal combustion engines possible.
  • the invention lies Problem based on creating a compact intake system, which with little effort to different internal combustion engines can be customized.
  • the intake pipe is longitudinally divided, so that at least two along a longitudinal pipe plane Intake pipe parts are formed, the air collector with a the intake manifold parts a coherent, one-piece base part forms and the other intake manifold part as an interchangeable part is executed, which forms a wall shell of the air collector.
  • the base part can be identical for different engine variants be made, whereas the interchangeable part to the respective Requirements especially with regard to the motor size and - performance data can be adjusted. Because of the one-piece Execution of a suction pipe part with a wall section of the Air collector is a particularly compact size.
  • suction pipe and wall part of the air collector can in particular also be formed in one piece and for example by injection molding manufactured as a common plastic component become.
  • an interchangeable intake manifold part with modified geometry different intake manifold lengths or Intake manifold volumes can be realized that match the respective internal combustion engine are adjusted.
  • the remaining intake manifold parts and the remaining wall sections of the air collector - the base part - can are retained unchanged, which on the one hand means the variety of parts and thus the tool costs are reduced and on the other hand also the design and size of the intake system in the Mainly be maintained.
  • the intake manifold part forming the interchangeable part can for example by welding firmly and indissolubly to the Base part to be connected. However, there may also be one detachable connection into consideration.
  • a pipe end piece protrudes of the interchangeable intake manifold part into the interior of the air collector.
  • the length of this protruding intake manifold, which is part of the interchangeable intake manifold part forms, determines the total length of the intake manifold. Therefore it is generally sufficient to use different intake manifold parts long pipe end piece to form the total length of the To vary intake manifold and to different internal combustion engines adapt.
  • the pipe end fitting protruding into the air collector requires no additional space, which makes it special compact design can be achieved.
  • a radially projecting stop can be provided on the pipe end connector be in the installed position on the inside wall of the Air collector supports, which on the one hand facilitates assembly is given and on the other hand an airtight seal between the interchangeable intake manifold part and the air collector is supported. Between the stop and the inner wall of the Air collector, a sealing element can be arranged.
  • the exchangeable intake manifold part expediently forms an upper shell of the suction pipe and the wall part connected to it a cover shell of the air collector.
  • the lower shell of the suction tube interchangeable, with in In this case, only one wall side of the air collector is expediently in one piece with the lower shell.
  • the intake system 1 shown in FIG. 1 for an internal combustion engine comprises an air collector 2 and several, from the air collector 2 branching suction pipes 3, of which, however, in Fig. 1 only one is shown in section, with the suction pipes too led and over the cylinder inlets of the internal combustion engine to attach a flange 10 to the cylinder head of the internal combustion engine are.
  • Both the air collector 2 and each suction pipe 3 are formed in two parts.
  • Each suction pipe 3 is divided lengthways and consists of two intake manifold parts 4 and 5, one of which the upper intake manifold part 4 an exchangeable upper shell and that lower suction tube part 5 forms a fixed lower shell.
  • the air collector 2 consists of a box 6 and an interchangeable one Lid shell 7.
  • the lid shell 7 forms with the upper, exchangeable or insertable intake manifold part 4 a common one-piece component.
  • Box 6 of the air collector 2 forms with the lower intake manifold part 5 - the lower shell of the Intake pipe 3 - also a one-piece component.
  • plenum and intake manifold are useful as a plastic injection molded component manufactured, the lid shell 7 of the air collector 2 with the upper intake manifold part 4 is a common injection molded part and in accordingly the box 6 of the air collector with the lower one Intake pipe part 5 forms a common injection molded part.
  • the lid shell 7 and that related to the lid shell upper suction tube part 4 are detachable and replaceable and can with fasteners 11 and 12 with the box 6 and the lower intake manifold part 5 are connected.
  • Upper and lower intake manifold part can also be inseparable from each other are connected, for example by welding.
  • a Rohrendstutzen 8 formed, which in the assembled position in protrudes the interior of the air collector 2 and open to it Expanded like a trumpet.
  • This pipe end connector 8 is designed as a continuous circumferential tube, whereas the section outside the air collector the upper intake manifold part 4 designed as a half-shell is complementary in the assembled position of the lower intake manifold part 5 is supplemented to a common intake manifold.
  • the total length by varying the length of the pipe end connector 8 of the suction pipe 3 can be varied, the other The geometry of the intake system can be retained unchanged can. If necessary, it can also be useful, alternatively or additionally the geometry of the lid shell 7 of the Air collector 2 to vary, also to change the Suction pipe length and / or the air volume in the air collector and to reach the intake manifold; this case is also in the figures shown, in which the lid shell geometry differs.
  • At the pipe end piece 8 is a one-piece, radially over the outer wall stop 9 protruding from the pipe end fitting, which is installed on the inside wall of the air collector box 2 is present.
  • the stop 9 makes installation easier represents.
