Definitions

  • the invention relates to an intake system for a multi-cylinder internal combustion engine, the intake system being held in a vibration-decoupled manner above the cylinders on the internal combustion engine.
  • DE-36 41 811 C1 discloses an intake system for a multi-cylinder internal combustion engine, which is held on the cylinder head in a vibration-decoupled manner with the interposition of elastic bearing elements.
  • the bearing elements are stressed between the intake system and supports on the cylinder head by means of screw connections.
  • the invention has for its object to design an intake system so that a simple and quick installation on the internal combustion engine is ensured and at the same time optimal vibration decoupling of the intake system from the internal combustion engine is achieved.
  • the arrangement of a decoupling element acting between the intake system and the cylinder head, which is subjected to tensile stress, and a further decoupling element which is arranged between the cylinder head and individual intake pipes of the intake system and which is subjected to pressure makes it possible to assemble the intake system in a few steps to disassemble. All that is required for this is access from above, vertically penetrating the intake system Clamping means, whereby the intake system is already connected to the internal combustion engine elastically and vibration-decoupled via the decoupling element supported on the cylinder head.
  • the forces transmitted from the clamping means to the intake system are based on the further decoupling elements which are placed between the intake system and the cylinder heads before the assembly of the intake system.
  • an intake manifold socket is arranged between the further decoupling elements, which simultaneously act as a seal, and a flange surface, the decoupling elements being supported on the flange surface via fastening pipes between adjacent suction tube sockets. This means that no further machined flange surface on the cylinder head is required to support these mounting pipes.
  • the individual intake manifold connecting pieces of a row of cylinders leading to each cylinder are formed in one piece together with the fastening pipes as a bridge.
  • these bridges are screwed to the flange surface by means of a fastening pipe arranged between the first and the second and between the third and the fourth intake manifold socket.
  • the decoupling elements are held on arms which are formed in one piece with the fastening pipes and which extend transversely to the bridge in the immediate vicinity of the cylinder heads.
  • the tension screws can thus easily penetrate an external area of the intake manifold, for example an air collector. To below the To reach the intake system in the V of the internal combustion engine, all that is required is to loosen four clamping screws, which makes the intake manifold removable.
  • the intake system is held on the internal combustion engine with dampers which comprise a pot-like housing detachably connected to the internal combustion engine.
  • dampers which comprise a pot-like housing detachably connected to the internal combustion engine.
  • a rubber-elastic mass is arranged, which is penetrated by a clamping sleeve provided with an end disc, which is detachably connected to the intake system.
  • the intake system and clamping sleeves are connected with lag screws which penetrate receptacles formed in the intake system almost vertically. This ensures good access to the connection.
  • a stop arranged in the receptacle limits the forces transmitted by the screwing of the adapter sleeve to the rubber-elastic mass, so that a desired identifier of the damper can be set.
  • the internal combustion engine 1 is formed together with an intake system 3 symmetrically to a perpendicular plane E, which receives a crankshaft, not shown.
  • the cylinder bank 2 has a cylinder head 4 (only indicated) with a hood 5 and a flange surface 6, into which inlet channels 7 formed in the cylinder head 4 open.
  • the intake system 3 which has an intake manifold 9, consisting of air collectors 10 and individual intake pipes 11, and intake manifold nozzles 12 arranged between the individual intake pipes 11 and the flange surfaces 6.
  • the intake manifolds 12 of a row of cylinders 2 are formed in one piece as a bridge 13, which forms part of the intake system 3.
  • the bridge 13 has two fastening pipes 14 formed integrally therewith. Arms 15 cast onto the fastening pipes 14 extend transversely to the plane E up to the vicinity of the cylinder heads 4.
  • the arms 15 releasably connect to them, designed as dampers 16, pot-like decoupling elements.
  • the dampers 16 have as a unit within a closed volume V a rubber-elastic mass 17, which is penetrated by an internally threaded 18 clamping sleeve 19, the lower end of which is formed by a disc 20 in contact with the mass 17.
  • the bridges 13 When mounting the intake system 3 on the internal combustion engine 1 for the first time, the bridges 13 are first screwed to the flange surface 6 by means of the fastening pipes 14 and further openings 28 formed in a flange 27.
  • the bridges 13 point Fuel supply lines 30 and injection valve receptacles 31, which are not explained in detail.
  • a sealing strip 26 is placed on each bridge 13.
  • a damper 16 is detachably connected to an arm 15 by a screw 33 accessible through the internal thread 18. Subsequently, the intake manifold 9 with the individual intake pipes 11 is placed on the sealing strips 26.
  • tensioning means designed as tension screws 35 are guided up to the clamping sleeve 19 and screwed to their internal thread 18.
  • An abutment shoulder formed as a stop 44 in the receptacle 34 limits the compression of the mass 17 to an optimum dimension for effective decoupling.
  • the entire intake manifold 9 can be detached from the internal combustion engine by the arrangement described above by loosening only four lag screws 35.
  • lag screws 35 e.g. quick-release elements provided with a bayonet lock are also used, which clamp the intake manifold 9 and damper 16 to one another with a rotation of 180 °.
  • the decoupling elements are only subjected to tension irrespective of the type of clamping means, the tensile forces transmitted by the damper 16 by means of the screw 33, the arm 15 and the fastening pipes 14 being supported in the flange surface 6 of the cylinder head 4.
  • the forces transmitted from the tensioning means to the intake manifold 9 are also supported on the flange surface 6 via the further decoupling element and the intake manifold stubs 12 which are thereby subjected to pressure.
  • FIG. 4 A second embodiment of the invention is shown in FIG. 4. Identical reference symbols denote the same components in both versions.
  • the intake system 3 is held on the internal combustion engine 1 in a vibration-decoupled manner with dampers 16.
  • the dampers 16 have a pot-like housing 36 which is detachably fastened to the internal combustion engine 1 with screws 33.
  • the rubber-elastic mass 17 penetrated by the clamping sleeve 19 is arranged, which is supported on a cover 38 held in a bead 37 of the housing 36.
  • Recesses 39 are arranged in the upper side of the mass 17 facing the cover 38, into which cut-out lugs 40 of the cover 38 forming two claws engage.
  • radially two sloping ribs 42 run radially on the disk 20, which engage in corresponding recesses 43 in the mass 17.
  • the assembly or disassembly of the intake system takes place with respect to the damper 16 in an analogous manner as in the first embodiment of the invention.
  • the mass 17 fills the volume V almost completely and thereby presses the disk 20 against the bottom of the housing 36 opposite the cover 38.
  • the clamping sleeve 19 is pulled out of the damper 16 and presses the mass 17 onto it a measure setting a certain identifier. This dimension is limited by an abutment shoulder formed in the receptacle 34 as a stop 44.
  • the clamping sleeve 19 is prevented from rotating with respect to the mass 17 or the mass 17 is rotated with respect to the housing 36 by the ribs 42 engaging in the recesses 43 or by the lugs 40 engaging in the recesses 39 .
  • the forces introduced by the tension screws 35 into the air collector 10 are supported, for example, via suction pipes (not shown) of the intake system 3.
