Abstract

본 발명은 내연기관의 실린더에 장착되는 피스톤의 구조에 관한 것으로서, 피스톤링의 냉각성이 향상되도록 하기 위해, 하부가 개구되고 상단부 외주면에 피스톤링이 삽입되는 링홈이 형성되는 것에 있어서, 상기 개구된 하부와 연통되게 소정의 냉각통로(10a)가 내부에 형성되고, 상기 냉각통로 내부에서 상기 링홈부위에 냉각핀(10b)이 돌출되게 형성되어, 오일펌프에서 압송된 오일이 개구된 피스톤(10)의 하부를 통해 냉각통로(10a)로 비산되고, 냉각통로(10a)로 유입된 오일이 냉각핀(10b)에 접촉하게 되어, 피스톤(10)의 링홈부위가 냉각핀(10b)에 의해 열교환되어 냉각이 빠르게 이루어지도록 하는 내연기관의 피스톤 구조이다.The present invention relates to a structure of a piston mounted to a cylinder of an internal combustion engine, and in order to improve the cooling property of the piston ring, a ring groove is formed in which a lower part is opened and a piston ring is inserted into an outer circumferential surface of the upper end, wherein the opened lower part is formed. A predetermined cooling passage (10a) is formed in communication with the inside, and the cooling fin (10b) is formed to protrude in the ring groove portion in the cooling passage, the oil pumped from the oil pump of the opening (10) The oil flows into the cooling passage 10a through the lower portion, and the oil introduced into the cooling passage 10a comes into contact with the cooling fins 10b, so that the ring groove portion of the piston 10 is heat-exchanged by the cooling fins 10b for cooling. This is the piston structure of the internal combustion engine to be made quickly.
