The use of alternative fuels is a key area in the research and development of sustainable energy sources. However, during their application in vehicles, they affect the properties of lubricating oils, modifying their kinematic viscosity, and the fuel can influence the quality of the tribological boundary layer formed on surfaces. In this study, 0W20 viscosity lubricating oils contaminated with ethanol from engine dynamometer tests were examined using Fourier-transform infrared spectroscopy. The analysis included the extent of dilution with fuel in different oil change intervals, along with the presence of oxidation and anti-wear additive (ZDDP).
Kivonat
Az alternatív tüzelőanyagok alkalmazása kulcsfontosságú terület a fenntartható energiaforrások kutatásában és fejlesztésében. A gépjárművekben történő alkalmazásuk során azonban hatással vannak a kenőolajok tulajdonságaira, módosítják azok kinematikai viszkozitását, illetve a tüzelőanyag befolyásolhatja a felületeken kialakuló tribológiai határréteg minőségét. Jelen kutatásban motorfékpadról származó etanollal szennyezett 0W20 viszkozitású kenőolajok vizsgálatára került sor Fourier-transzformációs infravörös spektroszkópia segítségével. Az oxidáció és kopásgátló adalék (ZDDP) jelenlétén kívül a különböző olajcsere periódusokban vett minták tüzelőanyaggal történő hígulásának mértéke is elemzésre került.
