doi:10.3969/j.issn.1000-1093.2018.02.019

Abstract

Abstract: The different surface textures of cylinder liner has a significant effect on the performance of diesel cylinder liner-piston ring friction pairs, thus affecting the service life, reliability and economy of diesel engine. In order to improve the tribological properties of cylinder liner-piston ring friction pairs，the cylinder liners with different surface textures are test to obtain the friction characteristic data under the conditions of same speed and different loads. The tset results show that the friction characteristic parameters of cylinder liner are obviously different. The tribological properties of cylinder liners with surface textures under different running conditions are compared and analyzed. It is concluded that the cylinder liner with annular square groove is more suitable to run under low load, while anyway tank is more fit to run under medium and high loads. Key
