FIELD: engines and shafts.
SUBSTANCE: internal combustion engine crankshaft incorporates intersecting oil feed holes in the main journals and oil feed holes in crank pins. The main journal oil feed holes are located in the same plane with holes feeding oil to crank pins of the crankshaft extreme cranks. The aforesaid plane is arranged at the angle formed, on the one side, by the axis passing through the first and the last cranks and, on the other side, by the plane accommodating the axes of holes feeding oil to the crank pins of the first and the last cranks.
EFFECT: improved manufacturability thanks to minimum number of hole boring.
