An oil ling of the piston for engine prevents that the oil is flowed into the combustion chamber. An oil ling of the piston for engine comprises a spacer(221) installed at the outside circumference surface of the piston(200), a rail(222) in which a plurality of oil inductive grooves(223) is formed while being installed to be near to the inner wall of the cylinder(210) in order to change the movement route of the oil to the columnar direction. The oil ling of the piston for engine forms the oil film to scratch out the oil supplied to the cylinder inner wall. |
