Definitions

  • the invention relates to a multi-cylinder internal combustion engine with liquid cooling, a cylinder head and a cylinder crankcase connected to the latter and comprising cylinder liners around which the cooling medium flows.
  • the object of the invention is to provide an internal combustion engine which is lightweight and compact with functional cooling.
  • the main advantages achieved with the invention can be seen in the fact that through the cooling medium guide transversely to the longitudinal direction of the internal combustion engine, a duct system surrounding the particularly warm areas of the internal combustion engine can be realized for a relatively small cooling medium volume, which has a weight-reducing effect.
  • the reduced volume of cooling medium also ensures that the internal combustion engine quickly reaches its operating temperature, which has a favorable effect on fuel consumption and exhaust gas emission.
  • a separate and needs-based supply of cooling medium to the cylinder head and the cylinder liners is possible through the supply channel.
  • the feed channel and the outlet channel can be provided in a simple manner between the said internal combustion engine components.
  • Cross bores are used to connect the feed channel to the ring channels of the cylinder liners, which not only can be easily introduced via the recesses, but also, if necessary, for calibration of the coolant flow, e.g. can be used for internal combustion engines of different performance. Due to the arrangement of the feed channel adjacent to the exhaust valves, the principle of directionally cooling warm zones of the internal combustion engines is additionally supported. The different volume of the medium chambers of the inlet and outlet valves also contributes to this.
  • the type of arrangement of the - separate - cylinder liners used in receptacles of the cylinder crankcase enables relatively small cylinder distances and shortens the overall length of the internal combustion engine, which also has a weight-reducing effect.
  • the narrow area between the cylinder liners, in which a groove is provided can be effectively sealed.
  • the sealing sections of the cylinder head gasket in the area of the feed and outlet channel simplify the sealing between the cylinder head and the cylinder crankcase.
  • the multi-cylinder, liquid-cooled internal combustion engine comprises a cylinder head 2 and a cylinder crankcase 3; both are assembled in a horizontal connection plane A-A and are held in position by means of screws, not shown.
  • a cylinder crankcase 3 Provided in the cylinder crankcase 3 are a plurality of cylinder liners 4, 5, for example made of gray cast iron, which according to FIG. 1 are formed by separate components inserted into the cylinder crankcase 3. 2, the cylinder liner 6 is integrally - cast - connected to the cylinder crankcase 3.
  • the cylinder head 2 comprises exhaust valves 7 and intake valves 8, which run in a V-shape with respect to one another and are actuated by means of camshafts (not shown).
  • the flow of the cooling medium is marked with arrows "a".
  • the inlet 10 and the outlet 12 are the cylinder crankcase assigned to 3; but these can also be attached to the cylinder head 2.
  • the supply duct 9 and the outlet duct 11 are integrated in the internal combustion engine and run on their longitudinal sides C and D between the cylinder head 2 and the cylinder crankcase 3.
  • the supply duct 9 and the outlet duct 11 are formed by recesses 13, 14 and 15, 16 in the cylinder head 2 and the cylinder crankcase 3, the recesses 13, 14 and 15, 16 being introduced from the connection plane AA into the respective internal combustion engine components.
  • Cross bores 19, 20 are provided between the feed channel 9 and the ring channels 17, 18 surrounding the cylinder liners 4, 5, 6 (FIGS. 1 and 3). Further cross bores 21, 22 connect the ring channels 17, 18 to the outlet channel 11.
  • the cross bores 19, 20 and 21, 22 are machined via the recesses 13 and 15, their machining direction extending obliquely to a central longitudinal plane EE of the internal combustion engine 1 (FIG. 1).
  • the feed channel 9 runs adjacent to the outlet valves 7.
  • the coolant passes from the feed channel 9 via transverse bores 23 into the medium chambers 24 surrounding the outlet valves 7 and then flows, previously passing through the medium chambers 25 above the inlet valves 8, into the outlet channel 11.
  • the medium chambers 24 of the outlet valves 7 are larger than the medium chambers 25 of the inlet valves due to the temperature conditions prevailing there in terms of volume.
  • the cylinder liners 5 have flats 27, 28 and essentially the same wall thicknesses. The flats 27, 28 are formed by reducing the wall thickness (FIG. 8).
  • receptacles 29 (FIG. 5) of the cylinder crankcase 3 into which the cylinder bushings 4, 5 are fitted.
  • the wall thicknesses of the cylinder liners 4, 5 and the receptacles 29 are approximately the same.
  • the wall thicknesses of the cylinder liners 4, 5 and the receptacles 29 are optimized in the area of the cylinder liners placed next to one another, i.e. with good strength as thin-walled as possible.
  • a groove 30 is provided (FIG. 5), into which a one-piece metallic cylinder head gasket 31 is inserted.
  • the groove 30 is formed by angular recesses 32, 33 of the cylinder liners 4, 5.
  • the groove 30 is continued outside the mutually facing cylinder liners 4, 5 (FIG. 4), where it is represented by a wall 34 of the cylinder crankcase 3 and the respective recess 32 or 33 of the cylinder liners 4, 5. At a distance from the recesses 32, 33, a collar 35 is provided on the cylinder liners 4, 5 and bears against a support 36 of the cylinder crankcase 3.
  • the cylinder head gasket 31 (FIG. 7) is provided with sealing sections 37, 38. These are effective between the cylinder head 2 and the cylinder crankcase 3, specifically in the area of the supply duct 9 and the outlet duct 11.
  • the sealing sections 37, 38 have a metallic extension 39 of the cylinder head gasket 31, which carries a sealing body 40 made of elastic material - silicone.
