Beschreibung
Zusammenfassung:	The utility model relates to a piston cooling structure, and belongs to the technical field of automobile design and manufacturing. The piston cooling structure comprises a top cooling oil cavity, a long round hole is formed in the middle of the top cooling oil cavity and serves as an oil inlet hole of the cooling oil cavity, and round holes are formed in the two sides of the top cooling oil cavity and serve as oil outlet holes of the cooling oil cavity. The oblong hole is over against the oil injection range of the connecting rod small end oil hole; and the distance between the cooling oil cavity and the connecting rod small end is more than 3mm. The piston cooling structure can reduce the thermal load of the piston, reduce the phenomena of carbon deposition and piston ring clamping stagnation, reduce deflagration and improve the structural strength of the piston. 本实用新型涉及一种活塞冷却结构，属于汽车设计与制造的技术领域。本实用新型的活塞冷却结构包括顶部冷却油腔，所述顶部冷却油腔的中间设置有长圆孔作为冷却油腔的进油孔，所述顶部冷却油腔的两侧分别设置有圆孔作为冷却油腔的出油孔；所述长圆孔正对所述连杆小头油孔的喷油范围；并且所述冷却油腔与所述连杆小头之
