Determination of Dispersing-Stabilizing Properties of Motor Oils and Their Dirtiness in Performance Conditions

详细

Under the motor oil performance conditions, it is very difficult to determine the dispersing-stabilizing properties and the degree of dirtiness of the oil. These characteristics, however, have a great effect on the performance life of the oil until its replacement and the reliability of tractor and automobile operation. Relationships of changes in dispersing-stabilizing properties of motor oils with the content of additives and performance time in the engine were obtained by theoretical analysis and practical studies. The results of the studies on improvement of paper chromatographic method to determine the dirtiness of the oils under their performance conditions are presented.
