Abstract (English):
The paper discusses the issues of increasing the service life of automotive internal combustion engines by stabilizing the lubrication mode of crankshaft bearings. The study objective is to assess comprehensively the impact of lubrication parameters and structural features of bearings on their durability and engine life. The task of the work is to find out optimal lubrication conditions for increasing the service life of bearings. Methods of theoretical analysis, calculation of durability according to SKF method, as well as field tests of production engines were used. The novelty of the study is in a comprehensive assessment of the influence of lubrication parameters, design and materials on the life of bearings. As a result, it is found that stabilization of the lubrication mode makes it possible to increase the life of crankshaft bearings by 18-25%. The results of the research confirm the possibility of introducing the proposed engineering solutions into mass production to improve the reliability of automotive engines.
