FIELD: engine building.
SUBSTANCE: piston (20) for reciprocating piston internal combustion engine includes piston head (5) and piston skirt (1). Piston head (5) has circumferential belt (6) of piston rings with at least one annular groove for piston ring, and also in area of belt (6) of piston rings—circumferential channel (2) of cooling. Cooling channel (2) extends from the piston ring belt to wall (10) of piston skirt (1). At that, cooling channel (2) in area of wall (10) of piston skirt (1) with at least one first through hole (31) is hydraulically connected to working sleeve for piston. Piston (20) has oil-ingot fin (41), which is located in cooling channel (2) such that part of oil, reciprocating back-and-forth spread in cooling channel due to piston movement, falls on oil catching rib (41) and is directed by oil shed rib (41) to said at least one first through hole (31). Also disclosed are a car and a system for supplying a vehicle piston with a lubricant.
EFFECT: technical result consists in reduction of friction of piston skirt.
