Abstract RU 2260721 C2

FIELD: mechanical engineering.

SUBSTANCE: system comprises the inlet opening of the oil passage in the crankshaft located from bellow in the bottom insert of the main journal when the crankshaft is in the intermediate position of the working stroke and output opening of the oil passage located in the top insert of the crankpin when the crankshaft is in the same position. The groove in the top connecting rod insert is made to be bypassed around the openings for supplying oil to the top head of the connecting rod to prevent against the pressure drop in the lubricant system.

EFFECT: increased service life of crankshaft and inserts of main journal and crankpins.
