Zhuravel' D. Increasing of use efficiency of mobile period agricultural engineering by prolongation of expectancy of motor oils

The object of researches is the processes of changes of tribotechnical and chemmotological properties of engine oils at farm machinery operation. The purpose is the de-crease of engine oil consumption by the prolongation of its service life. The plant YBOM-200 and mobile module for restoration of engine oil chemmotological properties are designed at TSAA and introduced into operation. The re-sults of the work are introduced to the farm enterprises of Pogrebischensk region, Vinnitsk oblast and Novokahovsk agrotechnical college of Kherson oblast. The efficiency of introduction of engine oil service life prediction method equals 104,2 grn per a tractor. The results may be used by scientific research and design institutions in the system of technical maintenance
