Abstract: Of scientific and practical importance are the study of the effect of products formed during the preliminary temperature control on the processes occurring during the oxidation of engine oil and antiwear properties. For this purpose, a set of instruments was used including: a device for testing the heat resistance of oils in the temperature range from 160 to 300 °C; photometric device for direct photometry; a device for determining thermal and oxidative stability; low-volume viscometer; device for testing friction materials; digital microscope; laboratory scales, allowing to determine the optical properties, kinematic viscosity, evaporation and anti-wear properties of oxidized and thermostatically controlled oils.
This paper presents the results of a study of the effect of temperature decomposition products, preliminary thermostating on the anti-wear properties of Lukoil Super 10W-40 SG/CD partial-synthetic engine oil. The effect of preliminary thermostating on antiwear properties has been determined, optimal temperature of preliminary thermostating has been selected at which there is an increase in antiwear properties when comparing thermostatted engine oils at certain temperatures and commercial oil that is not exposed to temperature.
