Friction force measuring system between cylinder and piston ring

摘要

The present invention relates to a system for reducing the friction between the cylinder and the piston ring which greatly affects the performance of the engine, it is almost impossible to directly measure the friction force between the piston ring and the cylinder inserted in the piston moving up and down at high speed Since there is a problem, the hydraulic pressure is supplied to the frictional force generating device 12 that generates the frictional force between the piston ring and the cylinder, the drive unit 11 that drives the frictional force generating device 12, and the frictional force generating device 12. Friction force measuring unit 10 consisting of a hydraulic pump 13, a load cell 14 for detecting the vibration generated by the friction force generating device 12, and a bracket 14 'for supporting the load cell 14 ) And a display unit 20 that displays the friction force detected by the friction force measuring unit 10 so that the tester can check the vibration force of the oil film formed on the outer circumferential surface of the cylinder liner 12b. The friction force between the cylinder and the piston ring can be expected to improve the engine performance by optimizing the lubrication characteristics according to the lubrication characteristics. will be.
