Spectroscopic Study and Analysis of the Content of Residue Elements in Marinol RG 1240 Oil after Working in Various Types of Engines

Abstract

During exploitation, the engine oil undergoes the irreversible aging process that is – degradation. The speed of this process is affected by many factors such as high temperature, pressure, power output, oxygen from the air, mechanical shear forces, type, structure, and technical condition of the engine, time and conditions of work and also used fuel. In the article, the author shows that also the purpose of the engine influences the degradation of the engine oil. Using the method of optical emission spectrometry in accordance with ASTM D 6595 standard, the concentration of trace elements like: Ag, Al, B, Ba, Ca, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, Si, Ti, V, Zn, was determined. The samples of engine oil – Marinol RG 1240 were checked after various periods of use in three different engine types Cegielski – Sulzer.
