The Internal Combustion Engine Piston Ring - Cylinder Liner Friction And Wear Performance Study

The paper is mainly focused on the abrasion process between piston ring and cylinder. Piston ring, which is apt to be worn out, is the key part of engine. The quality of piston ring affects the capability of engine. Abrasion between piston and cylinder is mainly abrasive wear.After the discussion of some fundamental theory and research ways about abrasive wear, the paper deeply studies the mode and specialty of abrasion between piston ring and cylinder. By studying the design of other experiment machine, I took drill machine as the base and power, and then devised the measure equipment and experiment equipment that is can be used to research the friction and abrasion between piston ring and cylinder. The equipment provides more experiment ways. On the base of the equipment we can design more research project under variable condition, load and rotate speed. I analyzed the experiment results produced by the equipment and found it accorded with the wear law. At the same time I acquired the abrasion characteristic about the wear between piston ring and cylinder. I reached the due study aim and result.
