Definitions

  • the German patent DE 40 01 140 C1 shows and describes a coolant guide in a cylinder crankcase shown in sections in cross section of a liquid-cooled V-engine.
  • V space of this V engine are in Machine longitudinal direction molded and lockable by a separate cover Coolant channels for a coolant inlet and a coolant outlet with respect to the cooling jackets provided in the cylinder banks. Consequently one of the cylinder banks is the coolant inlet channel and the other cylinder bank is the Coolant drain channel assigned adjacent, both coolant channels in the essentially separated by a solid rib, triangular in cross section are.
  • Each of the coolant channels is in the same with the adjacent cooling jacket limiting cylinder bank via openings in the cylinder bank limits in direct connection, each coolant channel with the cooling jacket of the another, spaced-apart cylinder bank via angular channels arranged in the rib is in a coolant-carrying connection.
  • the invention is based, for a generic, in particular the task engine designed as a V-engine to show improved coolant management with a much simpler construction with better heat distribution.
  • connection of the inlet line and the connection are in an embodiment of the invention the drain line substantially averaged to the longitudinal center plane of the cylinder crankcase arranged, which advantageously in one at a Front side of the cylinder crankcase arranged coolant pump at different V-angles achieved a uniform pump arrangement and design is.
  • the drain line is used to automatically support the ventilation of the coolant rooms cover that closes in the longitudinal direction of the machine in the direction of the connection trained for the coolant pump increasing.
  • a liquid-cooled internal combustion engine in particular designed as a V-engine 1 with cylinder banks 2, 2 'arranged inclined to one another comprises a cylinder crankcase 3 and the cylinder banks 2, 2 'separately assigned cylinder heads 4, 4 '.
  • the coolant flows according to a cross flow indicated by the arrows "B" of the cylinder heads 4, 4 'into the inner cooling jackets adjacent to the V space 8 7, 7 'of the cylinder banks 2, 2' from which the coolant through throttle openings 11 in cylinder bank boundaries 12 in the lower section of the V space 8 into a by means of transverse walls 13, 13 'on the housing end and a separate one Cover 14 trained drain line 15 passes.
  • connection 17 of the feed line 9 for a coolant pump 18 a geodetically arranged connection 19 of the Drain line 15 is assigned to the coolant pump 18.
  • connection 17 of the inlet line 9 and the connection 19 of the outlet line 15 substantially averaged to the longitudinal center plane 20 of the cylinder crankcase 3 arranged, with which on an end face of the cylinder crankcase 3 arranged coolant pump 18 one at different V angles uniform pump arrangement and pump design can be achieved.
  • the drain line 15 is from one in the direction Coolant pump connector 19 closed cover 14 rising. Further ventilation points are at geodetic high points in the Cylinder heads 4 and 4 'are provided.
