Title: Hybrid Ionic-Nano-Additives for Engine Lubrication to Improve Fuel Efficiency

Abstract

We developed a new class of hybrid organic-inorganic/metallic nanoparticles (NPs) as additives for polyalphaolefin (PAO) for friction and wear reduction to improve engine energy efficiency. The hybrid additives were synthesized by using polymers, ionic liquid (IL)-containing polymers, organic ligands, or ILs to functionalize NPs. The tribological properties of these hybrid NPs or mixtures of NPs and ILs were studied by high contact stress ball-on-flat reciprocating sliding tests at 100°C. Significant reductions in friction and wear were achieved compared to PAO base oil. The lubrication mechanisms were elucidated by both experimental and simulation studies.
