‘Triangle Ester’ Molecules as Blending Components in Mineral Oil: A Theoretical and Experimental Investigation

The present work explored the use of fatty acid ‘Triangle ester’ molecules (Epoxidized Ester (EE), and Thiirane (TE)) as antifriction antiwear additives at varying levels for Group I II mineral base oils using standard ASTMD-4172B four-ball test. Relative to neat oil, EE blends showed improved by ~61% ~42% properties ~32% ~41% in oils, respectively, while TE friction reduction ~65% ~40% wear ~93% ~50% relative same stock. Time evolution their with oil (modeled hexadecane) w.r.t. conformational changes, adsorption energy, intermolecular effect applied stress were estimated theoretically MD simulations. Further, optimized these effectiveness a blending component commercial engine (CEO) could reduce CEO ~30%, respectively.
