Spectrometric investigation of internal combustion engine oil

One of the ways to improve the efficiency of internal combustion engines is by reducing fuel and lubricant costs. The major cost of engine oil is due to the need to replace it regularly. Extending the service life of the oil based on the evaluation of its actual condition provides a significant reduction in operating costs. The article presents the results of the evaluation of changes in oil performance using spectrometric methods of oil sample analysis. Spectrometric methods allow to estimate promptly the intensity of accumulation of wear products, impurities, additives degradation degree, its viscosity index, oxidation, alkalinity in the oil. The results of spectrometric analyzes can also be used to assess the technical condition of the engine and the intensity of wear of its main parts. Results of researches confirm a possibility of scientific substantiation of prolongation of term of use of engine oils of internal combustion engines that provides decrease in operational expenses. The application of spectrometric methods of engine oil analysis also provides perfection of the engine maintenance system based on an objective estimation of the condition of the knots and mechanisms of the engine and the exception of not forced repairs and service. To increase the efficiency of the use of spectrometric methods of engine oil analysis, it is necessary to accumulate and generalize experience of their practical application and increase the duration of tests
