Dependence of the Dielectric Parameters of the Motor Oil on the Soot Content

Abstract

Reduction of noxious emissions and increase in oil drain intervals which reduce the maintenance cost of the vehicles and decrease a negative impact on the environment is one of the main trends in the modern automobile industry. The goals are achieved through introduction of the new systems and modes of engine operation, which in turn increases the rate of oil pollution and speeds-up degradation of the motor oils. Periodic monitoring of the oil characteristics can prevent the engine failure and reveal a decrease in the motor oil performance in due time which entails the necessity of developing the new methods for rapid analysis of motor oils. The development of the element base and increase in the accuracy of measuring devices provide their adaptation for determination of the qualitative characteristics of the motor oil. Nowadays, there are available measuring devices providing measuring of the dielectric characteristics of the motor oil within a wide range. The possibility of using measurement data for determination of condition of the motor oil is considered. The results of studying motor oils of various basic bases through determination of dielectric parameters are presented. Correlation analysis revealed clear dependence of the dielectric parameters of motor oil on the soot content.
