LUBRICANTS FOR FRICTIONAL PAIRS IN AUTOMOTIVE SYSTEMS: A REVIEW OF REQUIREMENTS AND CURRENT INVESTIGATIONS

ABSTACT: It’s well known that the performances of current technology oils are no longer sufficient to meet the increasing requirements of automotive lubricated systems. Innovative nanosized based additives could effectively act as friction modifier media in boundary and mixed lubrication regime through their unique behaviours at interfacial scale. Great expectations are also addressed towards the distinctive properties of the ionic liquids as lubricant media. They could likely replace some current technology additives such as detergents, anti-oxidants, anti-wear additives. The selection of appropriate lubricant additive is in an initial state, and more experimental research in physical and tribological properties are necessary.
