Thermal-oxidative stability control of motor oils by thermal energy with cyclic temperature change
Abstract
The results of the study of the thermo-oxidative stability of Castrol Magnatec R 10W-40 SL/CF partially synthetic engine oil with cyclic test temperature changes from 150 to 180 °C and from 180 to 150 °C taking into account the thermal energy absorbed by the products of oxidation and evaporation are presented. The graphical dependences of the decimal logarithm of the thermal energy absorbed by thermostatic products on the decimal logarithm of the test time are obtained, which are described by linear equations in the cycles of increasing and lowering the test temperature, which made it possible to determine the effect of time on the indicators of thermo-oxidative stability.
