Definitions

  • the invention relates to an internal combustion engine with an engine, which has reciprocating pistons and a cylinder block, with a cylinder head and with a separate outer structure for sound reduction, which on its underside by a rigid component, e.g. a lead frame, is closed, so that the outer structure is significantly stiffened by forming a box closed on all sides.
  • a rigid component e.g. a lead frame
  • the invention has for its object to remedy these disadvantages, the construction effort should be kept as low as possible.
  • this is achieved in that the engine is connected to the outer structure only via the rigid cylinder head, the outer structure being attached to the cylinder head, e.g. is screwed tight.
  • the cylinder head, the cylinder block and the outer structure are additionally acoustically decoupled by a cylinder head gasket, which additionally significantly reduces the structure-borne noise excitation of the outer structure.
  • the outer structure can have a circumferential flange which carries the oil pan. This further increases the rigidity of the outer structure.
  • the size of the oil pan which preferably consists of layer material (sandwich sheet), can advantageously be adapted to the excitation center in order to minimize its noise emission.
  • the side parts of the outer structure can be connected to one another by means of at least one transverse screw connection passing through the crank chamber, as a result of which the level of rigidity of the outer structure can be advantageously influenced.
  • attachments, engine mountings and Gearboxes are attached to the engine and these spacers penetrate the outer structure and are decoupled from structure-borne noise via elastic seals.
  • the "box”, which is closed on all sides, is therefore not subjected to any additional force exceptions except for its own weight. The effect achieved is less sound radiation with less construction work.
  • the power-carrying engine 1 together with its outer structure 4 is screwed onto the cylinder head 3 via the cylinder head gasket 2.
  • the outer structure 4 is screwed onto the cylinder head 3 via the cylinder head gasket 2.
  • the rigid cylinder head 3 is additionally acoustically decoupled from the outer structure 4 via the cylinder head gasket 2.
  • the outer structure 4 is closed by a lead frame 5 in the form of a rigid shell with an opening 6 for dismantling the connecting rod cover 7 at the bottom.
  • the additional possible cross screw connections 20 mutually support the walls at suitable points.
  • the oil pan 8 is sealed as high as possible on a flange 9 on the outer structure 4.
  • the transmission-side flywheel housing 10 is fastened to the outer structure 4 and the lead frame 5 in order to increase the rigidity of the motor-transmission unit. This also reduces the structure-borne noise level introduced by the engine into the transmission.
  • the engine 1 consists of the moving parts: piston 11, connecting rod 12, crankshaft 13 and the cylinder block 14, the bearing bracket 15 and the bearing bracket 16.
  • a loader 17 is fastened to the outer structure 4 via a holder 19.
  • the transmission is attached to the engine 1 via cylindrical intermediate pieces 21.
  • the passage through the outer structure 4 is sealed by elastic seals 22. These can be vulcanized with the intermediate pieces 21 or designed in the manner of shaft seals.
  • the brackets 23 for the engine suspension can be screwed to the inner structure via such intermediate pieces 21.
  • the console 23 or similar components can also be used for receiving units 24. The result is a "box" which is closed on all sides and which, apart from its own weight, does not experience any additional force. The effect achieved is less sound radiation.
  • a turbocharger is provided, of which the supercharger 17 attached to the cylinder head 3 is shown.
  • the structure-borne noise decoupling between the charger 17 and the cylinder head 3 can be accomplished by an element 18 which is flexible in the axial direction.
