Tribotechnical Diagnostics – Analysis of Engine Oil Degradation Via Oil Properties of Sae 10w-30 in Tatra Phoenix During 9 Months of Use

This article discusses selected degradation elements in the context of tribodiagnostic measurement. Four engine oil (EO) measurements were made to monitor changes in selected properties during 4,546 km of operation. EO samples were taken from the Tatra 815 Phoenix at three-monthly intervals. All samples were measured in the tribodiagnostic laboratory of the Armed Forces Academy, Department of Mechanical Engineering, on SpectroVisc Q-3050, Spectro Q1000 Fluid Scan, SpectroCube, FeroCheck and an electron microscope to perform photo-documentation of the separation membrane and separation filter results. The paper presents the measurements on the SpectroCube, FeroCheck and the electron microscope in more detail.
