FIELD: engine building.
SUBSTANCE: invention can be used in internal combustion engines (hereinafter – ICE). A device for lubrication of connecting rod bearing (46) on crankshaft (24) of ICE is proposed. The device includes piston (10) with working fluid channel (12), in particular lubricating-cooling fluid (for example, oil), and outlet channel (26) connected to channel (12) via fluid. The device includes connecting rod (22) connected to piston (10) by a pivot connection, large hole (44) in a connecting rod head, and connecting channel (48). Large hole (44) in the connecting rod head is made for accommodation of connecting rod bearing (46). Connecting channel (48) forms a direct connection via fluid between outlet channel (26) and large hole (44) in the connecting rod head, due to which working fluid is supplied from channel (12) to large connecting hole (44) through outlet channel (26) and connecting channel (48). Thereby, connecting rod bearing (46) is lubricated with cooling oil from working fluid channel (12) in piston (10).
EFFECT: it is possible to refuse from labor-intense and durability-reducing holes in crankshaft (24) for equipping connecting rod bearing (46).
