Definitions

  • the invention relates to a liquid-cooled internal combustion engine according to the preamble of claim 1.
  • a generic internal combustion engine is known from DE-A 28 28 466, the aim of which is to achieve a flow as uniform as possible around the cylinder liners.
  • the supply of coolant takes place via a coolant supply channel, while the actual distribution of the coolant around the cylinder liner takes place through longitudinal channels which are specially formed in the cooling chamber.
  • the longitudinal channel and the coolant supply channel must be specially formed by appropriate cores during the casting process of the crankcase and cause considerable expenditure in terms of shape.
  • the invention is based on the object of designing the inlet to the cooling chamber in a generic internal combustion engine in such a way that a different cooling capacity can be achieved over the axial height of the cooling chamber, the crankcase together with the inlet being designed to be structurally simple and rigid at the same time.
  • the inlet into the cooling space is incorporated as a simple slot in the crankcase area surrounding the cylinder tube.
  • the slot in the crankcase wall can optionally be machined after the casting process and the wedge-shaped design, by means of which a different cooling capacity is achieved over the height of the cooling chamber, can be varied according to the requirements. For example, it is conceivable to enlarge the slot in a supercharged internal combustion engine of a series by simple mechanical reworking in the area of the upper end of the slot, so that a higher cooling capacity is achieved in this area.
  • the simultaneous arched design of the slot in this area made it possible to introduce the forces exerted by the cylinder head onto the crankcase in a favorable, in particular stress-free manner.
  • 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 chamber 7 extends over 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.
  • 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 about about 1/4 of the height of the cooling chamber 7.
  • a cooling liquid channel 11 At the outlet 10 joins in the crankcase 2, a cooling liquid channel 11 at which derives the exiting cooling liquid in the cooperating with the cylinder liner 1 cylinder head . All liquid media such as water or oil are suitable as cooling liquid.
  • the inlet slot 8 has an approximately height-to-width ratio of 8: 1.
  • the slot 8 is tapered in both its upper and lower region. While this tapering is formed in the shape of an archway in the upper region 12 adjoining the crankcase cover plate 4, the Slit 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 manufacturing point of view.
  • the detailed view of the outlet 10 shown in FIG. 2 has an approximately height-to-width ratio of 5: 3.
  • the outlet 10 is approximately oval in cross-section, the arched design provided in the upper region 14 adjoining 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.
