EXPERIMENTAL CONFIRMATION OF THE PROJECT PERIOD TO REPLACE THE ENGINE OIL OF THE KAMAZ R6 ENGINE

The article is devoted to solving the actual scientific research task of confirming the design extended period for replacing engine oil for the advanced automobile diesel engine of the KAMAZ R6 family. The main goal of scientific research is to improve of consumer properties and efficiency of vehicle operation by increasing the frequency of their maintenance. The solution of the problem within the framework of this article is to assess the performance of a particular brand of modern high-tech engine oil from long-term operation and determine the period for its replacement in engines of the KAMAZ R6 family. The methodological apparatus for solving this problem was based on the developed algorithm for allowing motor oils to be used in KAMAZ engines. Based on the results of a complex of laboratory, bench and operational tests, the performance of the Lukoil Avantgarde Professional ACEA E4 / E7 SAE 5W-30 engine oil in the KAMAZ R6 family engines was positively assessed, and the declared replacement period of 150 thousand km was confirmed. The scientific novelty of the results obtained lies in the fact that new specific dependences of the quality indicators of modern high-tech engine oil Lukoil Avantgarde Professional ACEA E4 / E7 SAE 5W-30 on long-term operation during bench and operational tests of the KAMAZ R6 family diesel engine have been established. The theoretical value for the development of the branch of science “Operation of road transport” lies in the fact that the identified patterns contribute to the study of the efficiency and quality of operating materials, the patterns of changes in characteristics, performance indicators, the determination of consumption standards and rational service life of operating materials. The positive effect of this is the improvement of the processes of organizing the maintenance of vehicles, which helps to ensure their operational reliability and increase the efficiency of operation. The direction of further scientific research is the solution of the following complex problem - to investigate the patterns of consumption of engine oil and changes in the technical condition of the diesel engine of the KAMAZ R6 family from operating time to justify the optimal frequency of vehicle maintenance.
