| 摘要 |
The invention relates to an internal combustion engine having a piston-cooling arrangement ( 1 ) which has at least one spray device ( 2, 27; 2, 39 ) which is supplied with a coolant/lubricant via at least one supply passageway ( 3 ). The supply passageway ( 3 ) is arranged in a module ( 4 ) composed of a crankshaft-bearing structural element ( 6 ) and a crankshaft-bearing cap ( 7 ). The spray device ( 2, 27; 2, 39 ) is coupled to the crankshaft-bearing cap ( 7 ), a crankshaft-bearing shell ( 14 ) in the region of the supply passageway ( 3 ). Supply passageway ( 3 ) also connect to through-opening ( 16 ), so that coolant/lubricant can be directed via the supply passageway ( 3 ) to both the spray device ( 2, 27; 2, 39 ) and a crankshaft ( 17 ). The spray device ( 2 ) is designed as an oil-spray nozzle ( 27 ) or alternatively as a spray hole ( 39 ) integrated in the crankshaft-bearing cap ( 7 ).
