The aim of this study is to provide a detailed analysis of the relationship between the quantitative and qualitative performance parameters of a diesel engine lubrication system and the patterns of their change throughout the operational period. Understanding this dynamics is critical for enhancing the reliability and durability of diesel power units.
The methodology involved a comprehensive computational, analytical, and experimental investigation, utilizing physico-chemical analysis of motor oil samples and monitoring the engine's operational indicators.
It was established that ongoing changes in the physico-chemical composition of the motor oil are a key factor determining the dynamics of all quantitative and qualitative indicators within the lubrication system. The progression of oil aging (including polymerization) directly affects the rate of component degradation, significantly shortening its useful service life and necessitating strict adherence to replacement schedules.
The study also identified a specific risk: changes in the technical condition of the lubrication system can lead to oil fractions entering the fuel system. This constitutes a serious violation of operational standards, causing off-design operating modes and multiplying the risk of premature engine wear and failure.
In conclusion, the dynamics of change in lubrication system indicators is a complex, multifactorial dependency that can be represented by a graphical model. The practical value of this research lies in developing a foundation for optimizing maintenance strategies and increasing the operational efficiency of diesel engines.
