Motor oil spectral analysis for engine life-time prediction

Abstract

Technical diagnostics of the internal combustion engines, transmissions and other high-loaded units is a process regulated by technical requirements. However, depending on the intensity of operation and maintenance regulations, it is possible to change the technical and operational parameters of machine parts and mechanisms, as a result of frictional interaction of surfaces, temperature, ingress of aggressive chemical compounds and abrasive contaminants, as well as low physical and chemical quality indicators. The substantiation of the technology of spectral motor oil analysis to determine wear products is given in the paper. Determining the masses of metals in the motor oil during wear allows to predict the residual life of the engine and assess both the quality of the oil and the quality of the fuel.
