Definitions

  • the invention relates to an intake system for an internal combustion engine according to the preamble of claim 1.
  • an intake device for an internal combustion engine which comprises a plurality of intake pipes, which are each associated with a cylinder of the internal combustion engine, and a common collecting space for the intake pipes, via which the intake pipes are supplied with combustion air.
  • Each intake pipe is constructed in three parts, wherein a first intake manifold on the cylinder head side and a second intake manifold, which is connected to the air collector, are each longitudinally divided and complemented by a central intake manifold complementary.
  • This middle Saugrohrteil is designed to be interchangeable, which can be adjusted by changing the Saugrohrgeometrie this part different total lengths of the suction pipe.
  • the invention is based on the problem to provide a compact intake system, which can be adapted with little effort to different internal combustion engines.
  • the suction pipe is longitudinally divided, so that along a tube longitudinal plane at least two Saugrohrmaschine are formed, the air collector with one of the Saugrohrmaschine a contiguous, one-piece base part and the other Saugrohrteil is designed as a usable removable part, which forms a wall shell of the air collector.
  • the base part can be manufactured identically for different engine variants, whereas the interchangeable part can be adapted to the respective requirements, in particular with regard to the engine size and performance data. Due to the one-piece design of a Saugrohrerss with a wall portion of the air collector a particularly compact dimensions is achieved.
  • Suction tube part and wall part of the air collector may in particular also be integrally formed and produced for example by injection molding as a common plastic component.
  • the alternating part forming the suction tube part for example, by welding firmly and non-detachably connected to the base part.
  • the base part for example, by welding firmly and non-detachably connected to the base part.
  • the base part for example, by welding firmly and non-detachably connected to the base part.
  • a detachable connection into consideration.
  • a pipe end of the exchangeable intake manifold protrudes into the interior of the air collector.
  • the length of this projecting Saugrohrstutzens, which forms part of the exchangeable Saugrohrmaschines, determines the total length of the suction pipe. Therefore, it is basically sufficient to design intake manifold parts with differently sized pipe end stubs in order to vary the overall length of the intake manifold and to adapt it to different internal combustion engines.
  • the protruding into the air collector pipe end requires no additional space, which is a particularly compact design can be achieved.
  • a radially projecting stop can be provided, which is supported in the installed position on the inner wall of the air collector, whereby on the one hand a mounting relief is given and on the other hand, an airtight seal between the replaceable intake manifold and the air collector is supported.
  • a sealing element can be arranged between the stop and the inner wall of the air collector.
  • the exchangeable intake manifold forms an upper shell of the suction pipe and the wall part connected thereto a cover shell of the air collector.
  • the lower shell of the suction tube replaceable, in which case expediently only one wall side of the air collector is designed in one piece with the lower shell.
  • FIG. 1 illustrated intake system 1 for an internal combustion engine comprises an air collector 2 and a plurality of branched off from the air collector 2 suction pipes 3, of which in Fig. 1 however, only one is shown in section, wherein the suction pipes are guided to the cylinder inlets of the internal combustion engine and to be fastened via a flange 10 on the cylinder head of the internal combustion engine.
  • Both the air collector 2 and each suction tube 3 are formed in two parts.
  • Each suction pipe 3 is longitudinally divided and consists of two Saugrohr sculpture 4 and 5, of which the upper Saugrohrteil 4 a replaceable upper shell and the lower Saugrohrteil 5 forms a fixed lower shell.
  • the air collector 2 consists of a box 6 and a replaceable lid shell 7.
  • the lid shell 7 forms with the upper, interchangeable or insertable Saugrohrteil 4 a common, one-piece component.
  • the box 6 of the air collector 2 forms with the lower intake manifold 5 - the lower shell of the suction tube 3 - also a one-piece component.
  • Air collector and suction pipe are useful as a plastic injection molded component manufactured, wherein the cover shell 7 of the air collector 2 forms a common injection molded part with the upper Saugrohrteil 4 a common injection molded part and in a corresponding manner the box 6 of the air collector with the lower Saugrohrteil 5 a common injection molded part.
  • the cover shell 7 as well as the upper intake manifold part 4, which is connected to the cover shell, are detachable and exchangeable and can be connected via fasteners 11 and 12 respectively to the housing 6 and the lower intake manifold 5.
  • Upper and lower intake manifold can also be permanently connected to each other, for example by welding.
  • a pipe end 8 is formed, which protrudes into the assembly position in the interior of the air collector 2 and widens trumpet-like towards its open side.
  • This pipe end 8 is designed as circumferentially continuous circulating tube, whereas the portion of the upper Saugrohrmaschines 4 located outside the air collector is designed as a half-shell, which is complemented in the assembly position of the lower intake manifold 5 complementary to a common intake manifold.
  • the cover shell 7 of the air collector 2 in order to likewise achieve a change in the suction tube length and / or the air volume in the air collector and the suction tube; This case is also shown in the figures, in which the cover shell geometry differs.
  • a one-piece, radially projecting beyond the outer wall of the pipe end nozzle stop 9 is formed, which rests in the installed position on the inner wall of the box of the air collector 2.
  • the stop 9 represents a mounting relief.
