Definitions

  • the invention relates to an internal combustion engine with two rows of cylinders according to the preamble of claim 1.
  • a generic internal combustion engine is disclosed, the water pump of which is flanged to the cylinder block of a row of cylinders offset radially to the crankshaft at the front.
  • This pump conveys cooling water into the opposite row of cylinders via a connecting channel cast into one of the crankshaft bearings below the crankshaft.
  • the cooling jackets of the crankcase halves which are designed in open-deck design, are divided in half by a horizontal wall, so that the cooling water first flows through the bottom half, then in a U-shaped cross-flow through the cylinder heads and then through the top half of the cooling jackets.
  • the cooling water is routed via an outlet connection of the cylinder rows to a separate manifold, which is connected to the water cooler of the internal combustion engine.
  • the invention has for its object an internal combustion engine with two Rows of cylinders to improve the flow of cooling water is largely integrated into housing parts of the internal combustion engine and effective cooling is achieved at the same time.
  • the cooling water of both cylinder rows can advantageously be removed via a single, separate line arranged between a water / air heat exchanger and the internal combustion engine if the cooling water flows of the discharge channels are connected to one another via a transverse channel arranged in the upper wall. If this transverse channel is arranged adjacent to the end face of the internal combustion engine carrying the cooling water pump, the cooling water is first led from this end face along the supply channels in the direction of the opposite end face and from there back to the first end face for optimum cooling.
  • the cooling water flow leading can be in a particularly simple manner Integrate channels in the housing parts of the internal combustion engine, if this at be cast in directly during manufacture. As a modification to this, pipes be poured in.
  • An internal combustion engine with two rows of cylinders and a V-angle of 180 ° has a crankcase with two halves 1, 2 which are separated vertically along a division plane E - E and which comprise cylinder blocks 3, 4.
  • a longitudinal axis A runs in this plane E-E, which is also the axis of rotation of a crankshaft, not shown.
  • This is connected via connecting rods 5 to pistons 6, which move in a horizontal plane H - H.
  • Each cylinder bank is assigned a cylinder head 7 which is placed on a crankcase half 1, 2 in a parting plane T-T.
  • the heads 7 each have inlet and outlet channels 8 and 9 controlled by gas exchange valves, not shown.
  • the cylinders of each row of cylinders have cooling water jackets 10 and the heads 7 have cooling water channels 11.
  • a recess 13 for receiving a cooling water pump, not shown, is arranged on one end of the cylinder block 3.
  • This conveys cooling water to the cylinder rows 1, 2 via two outflow openings 14, one of these outflow openings 14 being designed as an inlet opening 15 into a feed channel 16 and the other being formed in a downward-directed outflow flange 17.
  • Both rows of cylinders have feed channels 16 arranged adjacent to the parting planes T - T below and parallel to the longitudinal axis A in a lower wall 18, 19. These channels 16 are connected to the cooling water jackets 10 and second connections 21 to the channels 11 via calibrated first connections 20 provided with a defined cross section.
  • the feed channel 16 which is spaced apart from the cooling water pump
  • the cylinder bank is connected to the outflow flange 17 by means of a connecting channel 22 connected.
  • a section 23 of this channel 22 is used as a heat exchanger tube 24 formed and runs with cooling fins 25 provided on its outer jacket in an oil pan 26 of the internal combustion engine.
  • the tube 24 bridges the Partition plane E - E and is on another, in the lower wall 19th trained section 27 of the connecting channel 22 connected.
  • corresponding discharge channels 30 arranged are connected to the cooling jackets 10 and the channels 11 of the cylinder heads 7.
  • Adjacent to the end face 12 is a collecting channel designed as a transverse channel 31 arranged in the walls 28, 29, which with an outlet 32 with a water / air heat exchanger, not shown, is connected.
  • the feed and discharge channels 16 and 30, the transverse channel 31 and the section 27 of the connecting channel 22 are cast into the walls 18, 19, 28, 29.
  • the cooling water pump conveys along the drawn arrows a cooling water flow over the inlet opening 15 or the connecting channel 22 into the feed channels 16, of which the Water flow from the end face 12 along the axis A according to the Cross sections of the connections 20 and 21 to the cooling jackets 10 and Cylinder heads 7 is divided.
  • the heads 7 are traversed in cross flow and the heated partial flows are fed to the discharge channels 30.
  • Drainage channels 30 the water flows back to the adjacent to the End face 12 lying transverse channel 31 and to its outflow connection 32.
  • the water flowing through the heat exchanger tube 24 heats the oil sump indicated by an oil level line S, so that the internal combustion engine reaches its operating temperature more quickly and as a result the pollutant emission is reduced. Due to the larger heat storage capacity of water compared to oil, the ribbing is arranged lying in the oil to achieve the best possible heat transfer. During continuous operation of the internal combustion engine, the oil reaches a higher temperature than the water flowing through the pipe 24, so that the oil is cooled.
