     摘要：从原理构思、结构设计、理论计算和试验测试等方面，对发明专利《ZL 2008 1 0150552.5，悬浮活塞连杆系统》技术，进行了探讨与实践。研究表明，针对燃油发动机活塞环与缸套的运行阻尼损耗，这种新型悬浮活塞压力润滑密封技术使传统燃油发动机摩擦损失功率的45.2%转化为有效输出功率。改变传统活塞飞溅的被动润滑为主动压力润滑，从结构设计上有效地保障了高温、高压燃气的密封，和润滑油消耗量的控制。结合实用新型专利《ZL 00237433.1，延长发动机使用寿命的活塞》的测试数据，对悬浮活塞技术做了充分的论证。

     Abstract: This paper investigates and practices the structural design concept, theoretical calculation and experimental test for the invention ZL 2008 1 0,150,552.5 A Suspension Piston and Rod System Technology. The result shows that this new pressure lubrication sealing technology based on suspension piston overcomes cylinder liner damping between the fuel engine piston rings and the cylinder liner, converting 45.2% power loss that is caused by frication in the conventional engines into effective output power. Different from the traditional passive splash lubrication, the active pressure lubrication can effectively seal air and gas at high temperature and control lubricating oil consumption. With test data of the utility patent ZL 00237433.1. To extend service life of piston engines, the suspension piston technology is fully demonstrated.
