Influence of seasonal conditions on the failure rate parameter of elements of the KAMAZ-43118 engine power supply system

Abstract

The reliability of the engine largely depends on the technical condition of the fuel equipment. It is known that the efficiency of cars depends on the operating conditions that change during the seasons of the year. The aim of the study is to establish the influence of seasonal operating conditions on the parameter of the failure rate of elements of the power supply system of KAMAZ-43118 car engines. The article presents a fragment of the research results. To achieve this goal, the theoretical part considers the factors affecting the reliability of the system under study. From the analysis of sources, it was found that with the change of the season of the year, road and transport conditions, natural and climatic factors significantly affect the food system. In this regard, the hypothesis of the study is put forward: natural and climatic factors significantly affect the reliability of the power supply system of KAMAZ-43118 car engines. At the first stage of experimental studies, statistical data on the operating time for failure of the power supply system of KAMAZ-43118 cars were processed, the elements of the system with the greatest number of failures were identified. At the second stage, the influence of air temperature on the parameter of the failure flow of the elements of the power supply system of KAMAZ-43118 car engines was established. With the help of correlation analysis, the significance of seasonal changes in natural and climatic factors is proved. At the third stage, a methodology for using the obtained data to adjust the volume of spare parts and materials in the warehouse is proposed. The scientific novelty of the research is to establish the regularities of the influence of air temperature on the parameter of the failure flow of fuel equipment elements of KAMAZ-43118 vehicles. The practical significance lies in the possibility of using the results of the study in the development of a methodology for optimizing the volume of spare parts and materials in the warehouse. Further research will be aimed at improving the reliability of the power supply system taking into account seasonal operating conditions by adjusting the frequency of maintenance.
