Branch from these channels 19, 20 and from channel 17 Inclined channels 21 in the bearing bridge 2, the 22 to the storage locations Guide the crankshaft.
  • the inlet opening 22 of the oblique channels 21 are closer in FIG. 5 shown.
  • the inclined channels 21 can with the two transverse channels 14, 20th preferably have the same oil inlet opening 19a.
  • the inlet openings of channels 19 and 21 or 20 and 21 are separated.
  • the oil channel 16 has an inflow at 23, which is connected to an oil pump 24 is.
  • the oil flows through the through an intermediate oil filter 25 in the channel 16 Channel 18 on the housing side to the oil channel 15. Before entering this channel 15 the oil flows through an oil / water heat exchanger 26.
  • the cylinder head screws 9, 10 and 9a, 10a are in bores 30 of the housing 1 and the heads 4 and 5 arranged, which simultaneously oil bushings form. For this purpose, they have a larger diameter than the screws. From these bores branch off connecting channels 31 into the oil channel 15. Likewise are 6 connecting channels 32 of the holes in the second housing half Bolts 9, 10 are provided in the oil channel 17. As a result, the oil from the Oil channels 15 and 17 to each head side 4, 5 through the holes in the Cylinder head screws 9, 9a and 10, 10a flow, including the holes an inclined channel 33 arranged in the head branches off.
  • Oil channels 15, 16 and 17 almost over the entire length of the crankcase 1, wherein in the housing halves 5 on both long sides, the oil channels 15, 16 and the housing half 6 is arranged only on one long side of the oil channel 17.
  • Each half 5,6 of the cylinder crankcase 1 has at least one opposite cast-on cooling channels 35, 36. Between Cooling channels 35 of a housing side, a starter receptacle 37 is provided is assigned to the housing half 6 and ends with the parting plane a-a.
