Abstract:

The interaction of high detergent oils with fine filtration materials is examined. It was found that surface tension can serve as a measure of the concentration of additives in lubricating oils. A unique relationship exists between the surface tension and the detergent properties of oils containing different concentrations of SB-3 additive. The process of absorption on oil filter elements is physical in nature. A formula was derived which permits quantitative evaluation of the amount of absorption of additive in the 28-138 degrees C temperature interval for circulation time of oil in the system from 5-20 hr. The second part of the article deals with the continuous delivery of additives to motor oils. A laboratory device was constructed which permits delivery of oil additive to the oil while the engine is operating.
