It has been established that in the process of hydrodynamic treatment of oil, the size of the particles of contamination decreased to 5 microns or smaller sizes. Such particles can significantly improve the anti-wear properties of the lubricating oil. Besides, during hydrodynamic dispersion, it is significantly heated due to throttling in connection with a sharp transition of the kinetic energy of the oil jet into the thermal energy. It was proved that such heating during hydrodynamic dispersion led to structural transformations of the oil, namely: the number of free radicals and the time of their chemical activity decreased. This resulted in improved antifriction and anti-wear properties of the oil. This was proved quite convincingly by the results of wear tests on the SMC-2 and FBM friction machines: the wear of friction samples decreased on average by 1.34 times.
