Definitions

  • the invention relates to an internal combustion engine with at least one liquid-cooled cylinder, whereby a cooling space is provided between the cylinder and an outer casing, fluid is conveyed through the operation of the internal combustion engine, and an F lüsstechnikszufluß and having liquid drainage.
  • DE-OS 31 18 498 describes an internal combustion engine with liquid-cooled cylinders, the engine lubricating oil being used as the cooling liquid here.
  • the oil enters the cooling chamber in the upper part of the cylinder near the cylinder head and flows axially along the cylinder wall into the crankcase under laminar flow conditions.
  • the radial thickness of the cold room is in the range between 0.15 and 0.4 mm.
  • a disadvantage of this arrangement is the risk of K rackens of the cooling oil and a V erlackens kühlölbe Seriesten the side of the cylinder wall after the engine from the full load, because the cylinder stores of its high heat capacity, a temperature, once attained, too long.
  • the invention has for its object to design the cooling of the cylinder of an internal combustion engine such that even after stopping the engine erlacken from the full load, a cracking or V of the cooling oil is avoided.
  • the heat-emitting surface of the cylinder increases.
  • the coolant can absorb heat faster, which improves cooling.
  • the material advantageously has a porous or perforated structure for better liquid flow.
  • the material is pressure-resistant in the radial direction with respect to the cylinder.
  • This has the advantage that the cylinder can then be made thin-walled, since an internal pressure which occurs in the cylinder is passed on via the cylinder wall and the material to a fixed housing which essentially surrounds the cylinder and which only accepts the temperature of the coolant. Due to the small wall thickness and the associated lower thermal conductivity of the cylinder tube, only a small temperature gradient occurs in the cylinder wall; ie there is a large temperature difference between the outer wall of the cylinder and the coolant, which increases the amount of heat that can be dissipated compared to thicker cylinder walls and at the same time reduces the temperature of the inner wall of the cylinder.
  • the thin cylinder tube can prevent the cooling oil from cracking or the cooling oil-flushed side of the cylinder from laking after the engine has been switched off from full load. Furthermore, the small wall thickness of the cylinder enables weight to be saved, and this requires less expensive production.
  • the cooling space is completely filled with the material. This achieves better cooling of the entire cylinder and reduces the transmission of noise through the material.
  • the material is composed such that its thermal conductivity decreases in the direction of the cylinder axis from the cylinder head to the crankcase. Due to this design, the heat dissipation of the cylinder is greatest in the area of the cylinder head, so that this high-temperature area is kept at a lower temperature, whereby temperature stresses in the axial direction of the tube are avoided.
  • a similar effect can be achieved by increasing the permeability of the material in the direction of the cylinder axis from the cylinder head to the crankcase. Due to the higher flow velocity of the K yerflüs- stechnik in the area of the cylinder head, there is ensured a higher cooling than in the region of the end facing the crankcase.
  • a further embodiment of the invention provides that the cylinder liner and the filler material manufactured as a component are manufactured in the cooling chamber as a single unit, the cylinder liner preferably being made of a non-porous material and the component being made of a large-pore material Sintered metal body.
  • the drawing shows a cylinder liner 2 ', which is embedded in a housing 4. Between the cylinder liner and the housing there is an annular cooling chamber 3, which has a coolant inlet 9 on its side facing the cylinder head and is open on its end side facing the crankcase 8 and forms a coolant outlet 10 in the crankcase 8.
  • a collar 1 in the upper region of the cylinder liner 2 ' stiffens it, fixes the axial position of the cylinder liner 2' in the housing 4 and seals the cooling space 3 to the outside.
  • the refrigerator compartment 3 is liquid-permeable processing up to serving as a coolant supply ring channel 5 with a ylinderachsrich- in Z, filled with good heat conducting material.
  • the ring channel 5 is connected via a channel to a bore 6 in the housing 4, which runs axially parallel to the cylinder axis with respect to the cylinder axis, to a coolant distribution line 7.
  • the cylinder 2 can be cast as a unit with an integrated cooling space 3.
  • the liquid-permeable, in particular oil-permeable, material preferably has a porous or perforated structure and thereby enlarges the heat-emitting surface of the cylinder and thereby improves the cooling. If necessary, the material can also fill only part of the cooling space 3.
  • the material is pressure-resistant in the radial direction with respect to the cylinder axis.
  • the cylinder can be thin-walled because a pressure in the cylinder 2 is passed on to the housing 4 by the material.
  • the material has a structure which sets the coolant flow in turbulence and mixes the coolant well.
  • the thermal conductivity decreases in the direction of the cylinder axis from the cylinder head to the crankcase 8. It may also be appropriate that the permeability of the material increases in the direction of the cylinder axis from the cylinder head to the crankcase 8.
  • the material can be designed as one component and specifically the cylinder liner 2 'and the component as one structural unit.
  • An advantageous embodiment would then be to manufacture the cylinder liner as a non-porous and the component as a large-pore sintered metal body.
  • the coolant especially the filtered engine lubricating oil
  • the coolant distribution line 7 is pumped via the coolant distribution line 7 through the bore 6 into the ring channel 5. From there it flows through the porous or perforated material. Due to the increased surface area of the cylinder, the cooling liquid can absorb the heat better and flows into the crankcase 8 after it has passed through the material.
