Analysis of degradation factors of motor oil in mining dump trucks

The main directions of improving the maintenance of dump truck engines and the relevance of studying the nature of engine oil degradation and simplifying diagnostic procedures are considered. The oil in each particular car will break down at its own pace, taking into account many factors that are not always controllable. A review of literary sources shows that most authors prioritize the negative impact of dusty roads, too cold or too hot conditions, and slopes exceeding 80%. Methods for assessing the condition of lubricating oil are considered, most of which are standardized. The degree of degradation of the engine oil is fairly reliably assessed using the above methods, however, the tribo-stresses of the engine should also be assessed. Please note that when changing the oil, information about previous wear will not be available. It is advisable to begin understanding the nature of degradation with a functional analysis of the engine elements and its lubrication subsystem. Next, it is necessary to describe the influencing factors and their limiting values. It is important to understand that in a complex technical system, factors work together to enhance the destructive effect. To clarify the rate of oil degradation, formulas for assessing the abrasive, corrosive and adhesive wear of engine components are proposed, in addition to existing methods. The direction of further research is the study of indicators of abrasive, oxidative and adhesive wear, as well as the development of predictive models for determining the limiting state of engine components.
