Definitions

  • the invention relates to a liquid-cooled internal combustion engine according to the preamble of claim 1.
  • the invention has for its object to achieve a uniform transverse flow around the cylinder liner in a generic internal combustion engine without guide devices in the cooling room over its entire height.
  • this object is achieved by the characterizing features of the first claim.
  • the height of the inlet slot - which is arranged in the crankcase wall surrounding the cooling chamber - corresponds exactly to the height of the cooling chamber. This eliminates the need for additional vents and pipes. The ventilation takes place through the inlet.
  • the slot-shaped inlet in the region of the upper crankcase cover plate is designed in the form of an arch. Through this arch-shaped design of the slot and a coolant distribution channel, which extends along a row of cylinders of an internal combustion engine, a rigid reinforcement of the crankcase cover plate and the cylinder liner support is achieved.
  • the bulkhead core in the area of the cylinder space in contrast to the solution with a coolant guiding device, is simple in design and manufacture. It may also be expedient to design the slot-shaped inlet in a wedge shape.
  • the tip side of the wedge is preferably arranged in the lower region of the inlet in order to cool the thermally most highly stressed zone in the region of the upper crankcase cover plate by a larger flow of coolant.
  • the cooling liquid preferably runs out of the cooling chamber through a further slot which is arranged on the side opposite the inlet in the region of the upper crankcase cover plate.
  • the drainage slot of the coolant is also advantageously arch-shaped in the area of the upper crankcase cover plate or oval. This design enables ventilation to be carried out into the area of the cylinder head without further ventilation openings and lines.
  • the arrangement of the outlet for the coolant in the area of the upper crankcase cover plate enables intensive cooling of the cylinder liner in its area which is subjected to the greatest thermal stress.
  • a cylinder liner 1 is shown, which is inserted into a crankcase 2. It is supported with an upper edge 3 on the upper crankcase cover plate 4.
  • grooves 5 are incorporated, into which sealing rings 6 are inserted, which seal the cylinder liner 1 against the crankcase 2.
  • a cooling space 7 is provided which is delimited by the cylinder liner 1 and the crankcase 2 and which surrounds the cylinder liner in a ring. The cooling space 7 extends approximately 3/5 of the total length of the cylinder liner 1.
  • an inlet 8 designed as a slot for cooling liquid is incorporated on one side, which extends over the entire height of the cooling space 7 in the exemplary embodiment shown.
  • a coolant distribution channel 9, not shown which extends along a row of cylinders of an internal combustion engine.
  • an outlet 10 is incorporated into the crankcase 2, approximately diametrically opposite the inlet 8.
  • the outlet 10 extends from the upper crankcase cover plate 4 starting at approximately 1/4 of the height of the cooling space 7.
  • the outlet 10 is followed by a coolant channel 11 in the crankcase 2, which drains the emerging coolant into the cylinder head interacting with the cylinder liner 1 . All liquid media such as water or oil are suitable as cooling liquid.
  • the inlet slot 8 shown in a detailed view in FIG. 2 has an approximately height-to-width ratio of 8: 1.
  • the slot 8 is tapered in both its upper and lower region. While this taper in the upper region 12 adjoining the crankcase cover plate 4 is arched, the slot 8 in its lower region 13 is approximately semicircular.
  • Such a design of the inlet slot 8 has proven to be favorable from a cooling, casting and production engineering point of view, although it may also be expedient to combine the arch-shaped design provided in the upper region 12 and the semicircular design of the inlet slot 8 provided in the lower region 13 swap or adapt each other in their form.
  • the detailed view of the drain 10 shown in FIG. 3 has an approximately height-to-width ratio of 5: 3.
  • the drain 10 is approximately oval in cross-section, the arched design provided in the upper region 14 abuts the upper crankcase cover plate 4, while the opposite side 15 is semicircular.
  • it can be useful to interchange the arched design of the upper region 14 with the semicircular design of the lower side 15 or to adapt the shape of the upper and lower training to one another.
