Definitions

  • the invention relates to an internal combustion engine according to the preamble of claim 1.
  • an internal combustion engine which has a cooling space between the cylinder or cylinder liner and a crankcase, through which coolant is conveyed during operation of the internal combustion engine.
  • a pressed sheet metal part is slid onto the outside of the cylinder or the cylinder liner, which is in particular designed as a snap ring or spring washer.
  • Spiral channels are arranged on the sheet metal part, through which the coolant is passed.
  • a disadvantage of this arrangement is that, despite the complex production, the pressed sheet metal part does not cause sufficient heat transfer from the cylinder to the cooling liquid.
  • the object of the invention is to improve the heat transfer in the cylinder by means of an easy-to-insert component, which requires a higher coolant speed and an enlarged surface.
  • the turbulence plates have turbolators, which by piercing and bulging individual sections of the turbulence plate, an easy-to-insert component is created, which improves the heat transfer due to a higher coolant speed and an enlarged surface.
  • the turbulence plates are advantageously corrugated in order to increase the turbulence-exciting effect of these plates.
  • the turbolators are arranged on one side of the turbulence plate. It is advantageous to fix the turbulence plates firmly to the cylinder or cylinder liner e.g. to be joined by spot welding, soldering or gluing.
  • the turbolators expediently have a square shape and protrude from the turbulence plate at an angle between 45 and 90 °.
  • turbolators are formed by approximately disk-shaped punchings in the turbulence plate. It is also expedient if the turbolators consist of two parallel recesses with subsequent bulging of the intermediate layer.
  • the turbulence sheets are advantageously produced from lubricating oil-resistant plastics or from aluminum.
  • FIG. 1 shows an internal combustion engine with a cooling chamber 3 arranged between cylinder 7 and crankcase 4, through which cooling liquid is conveyed during operation of the internal combustion engine.
  • An inflow 5 to the cooling space 3 is located at the end of the cooling space 3 facing the crankcase 4, while an outflow 6 is arranged at the end of the cooling space 3 facing the cylinder head, not shown.
  • a turbu is located within the cooling space 3 bilge sheet 1, which is pushed onto the outside of the cylinder 7. With this turbulence plate 1 it is achieved that the cylinder 7 is better cooled by the cooling liquid.
  • the turbulence plate 1 completely fills the radial width of the cooling space 3, while the turbulence plate 1, viewed in the axial direction of the cylinder 7, is located only in the upper end of the cooling space 3 facing the cylinder head. As a result, this part is cooled more intensively than the lower part of the cooling space 3 facing the crankcase 4.
  • Turbulators 2 are arranged on the turbulence plate 1, which have a square shape and protrude from the tubulence plate 1 at an angle a between 45 and 90 °. The angle, as can be seen in this figure, is advantageously approximately 80 °.
  • the cooling liquid flows around the cylinder 7 in the circumferential direction, the inflow 5 and the outflow 6, as already described, being arranged diametrically opposite one another.
  • the arrangement of the turbolators 2 on the turbulence plate 1 is such that the turbolators 2 are located on the turbulence plate 1 in different, superimposed planes, as seen in the circumferential direction of the cylinder.
  • the respective turbolators 2 adjacent in the axial direction of the cylinder 7 are arranged between the turbolators 2 located above and below.
  • a particularly advantageous swirling and thus cooling of the cylinder 7 results for the coolant flow.
  • FIG. 2 shows a turbulence plate 1 according to FIG. 1, in which case the turbolators 2 are arranged symmetrically on the turbulence plate 1, that is to say the sides of the turbolators 2 each pointing in one direction are all parallel to one another. It is also advantageous to arrange the turbolators 2 only on one side of the turbulence plate 1.
  • Fig. 3 shows a turbulence plate 1 with turbolators 2, which are formed by approximately disc-shaped punchings in the turbulence plate.
  • FIG. 3 a) shows these turbolators 2 with a different diameter d, while in FIG. 3 b) all turbolators 2 have the same diameter d.
  • turbolators 3 b) are arranged symmetrically to one another, ie the center points 9 of the turbolators 2, which are at an axial height of the cylinder, are all to be connected by a straight line.
  • the turbolators are arranged apparently without order on the turbulence plate.
  • certain parts of the cylinder can be cooled particularly intensively by the arrangement and shape of the turbolators 2.
  • FIG. 4 shows a corrugated turbulence sheet 1, the turbolators 2 in FIGS. 4a) and 4b) consisting of two parallel recesses with subsequent bulging of the intermediate layer 8.
  • 4b) shows an advantageous embodiment of the turbulence plate 1 according to FIG. 4a), the turbolators, ie the intermediate layer 8, being bulged out of the turbulence plate 1 against the curvature thereof.
  • the solid line denotes the turbulence plate 2 and the dashed line denotes the turbolators 2, ie the bulges from the turbulence plate 1.
  • the turbolators consist of circular punchings in the turbulence plate 1.
  • turbulence plates 1 It is advantageous to produce the turbulence plates 1 from substances that are resistant to lubricating oil. Furthermore, it makes sense to manufacture the turbulence plates 1 from aluminum.
