The Effect of Polymer Type Additives on the Efficiency of the Detergents and Dispersants in Motor Oils.

摘要

Detergent properties of pure chemical compounds and some commercial additives were determined. It was evident that the high values of detergent potential necessary in modern lube oil designs cannot be reached through single detergent additive. Experiments and measurements were carried out on polymer additives to determine their effect on the dispersancy and detergency of pure compounds or additive packages. The nitrogen containing polymethacrylates were found to be good sludge dispersants. (Author)
