Definitions

  • the invention relates to a liquid-cooled cylinder crankcase according to the preamble of claim 1.
  • Crankcases can be manufactured using die casting technology.
  • the volume of the cooling water space is the Requirements of the mold set. This volume can therefore not optimally designed for cooling the cylinders will.
  • the object of the invention is to provide a cylinder crankcase Generic type in which the cooling of Cylinder is optimized.
  • the displacer causes furthermore a significant reduction in the amount of cooling water, whereby a quick warm-up of the internal combustion engine positive effects on pollutant emissions Friction power, driving comfort and the response behavior of the Heating is achieved and the water pump output is reduced can be, which has a positive impact on fuel consumption affects.
  • the amount of cooling water can be further reduced if the Shape of the displacer to the shape of the cooling water space is approximated so that essentially only the gap between the displacer and the cylinders or the cylinders containing cylinder block is flowed through by cooling water.
  • a spoiler can be arranged, which is directed towards the Cooling water inlet connector extends and the cooling water flow divided into two sub-streams through through openings on both sides of the spoiler along the cylinders or the Cylinder block on one side and on the other side of the Cylinder crankcase are directed.
  • the land areas between the cylinders particularly at risk. To ensure good cooling of these areas ensure the inner wall of the displacer extend to close to these areas so that the Cooling water flow is forced to paint these areas and dead water zones are avoided.
  • the displacement body should preferably have a low heat capacity have what through an appropriate material, e.g. Plastic, and / or can be achieved in that the displacement body is designed as a hollow body.
  • the cylinder crankcase 1 has outer walls 2 which are upper Form flange surface 3 for a cylinder head, not shown and enclose a cooling water space 4, which to the flange surface 3 is open so that the crankcase in die casting technology can be manufactured.
  • a cylinder block 5 summarized cylinder 6 arranged in the cooling water room 4 in the cooling water room 4 in the cooling water room 4 in the cooling water room 4 are closed.
  • the cylinder block 5 is in one piece with the housing 1 and lies at a distance from the outer walls 2.
  • In the Cooling water chamber 4 opens into a cooling water inlet connection 7.
  • a displacer 8 is inserted into the cooling water chamber 4, the shape of which approximates the shape of the cooling water chamber.
  • the inner wall 9 of the displacer 8 limits with the Outer surface 10 of the cylinder block 5 a relatively narrow Gap 11, which with the inlet connection 7 via openings 12 (Fig. 2) in the wall of the displacer 8 in connection stands.
  • a spoiler 13 formed which is in Direction extends to the inlet nozzle 7 and the Splits the cooling water flow into two sub-flows through the openings 12 provided on each side of the spoiler in the Enter gap 11 and of which the one partial flow along the cylinder block 5 on one side and the other Partial flow along the cylinder block 5 on the other side of the cylinder crankcase 1 flows through the gap 11.
  • the inner wall 9 of the displacer extends 8 at a relatively short distance from the outer surface 10 of the cylinder block 5 and especially from the land areas 14 between adjacent cylinders 6, so that the cooling water is forced on the outer wall 10 of the cylinder block 5 to flow along and intensive cooling in particular also causes the critical web areas.
