Abstract

Detergent-dispersant (DD) effect is one of the most important properties of lubricants and fuels. To ensure these properties various types of additives are used in increasing amount in the performance additive packages. Among them ashless types and mostly polyalkenyl succinic anhydride derivatives are applied in high volumes. In this paper the main advantages of the ashless additives are presented showing the dependence of their properties on the molecule structure (monosuccinimides, bissuccinimides, mixtures thereof and polysuccinimide). Additionally, the interactions with other additives are shown which can determine the main tribological properties of the lubricants.
