“…This phenomenon supports the stability of the protective film. Hence, it provides better lubricating properties [40]. However, it needs to be proven in the future through in-depth research on tribosurface or based on a tribochemical point of view to clearly understand the lubrication mechanism of SOEGE and the major and minor components of SOEGE play a role in improving the lubricity of low-sulfur diesel.…”

The present study aims to show the tribological properties of soybean oil's ethylene glycol ester (SOEGE) and its effect on low-sulfur diesel fuel lubrication. The SOEGE or 2-hydroxyethyl ester was synthesized by a transesterification reaction of soybean oil and ethylene glycol with a potassium carbonate catalyst. The product was characterized using Gas Chromatography-Mass Spectrometry (GC-MS). Then, the lubricity of commercial diesel fuel (Pertadex) and SOEGE were tested alone using the High-Frequency Reciprocating Rig (HFRR) machine. Its mixture form with various product doses in Pertadex (0.2, 0.4, 0.6, 0.8, and 1% v/v) was also tested with the same apparatus. This study showed that the product's coefficient of friction and Wear Scar Diameters (WSD) were 0.057 and 154.4 m, respectively. This value is lower than Pertadex and Fatty Acids Methyl Ester (FAME) of Soybean oil from the literature. Furthermore, adding products into Pertadex can reduce the coefficient of friction and WSD of Pertadex. The Pertadex coefficient of friction was reduced from 0.161 to 0.135 after the addition of 0.8% product. At a concentration of 1% product, WSD Pertadex was successfully reduced by 39.42%. These phenomena imply that ester ethylene glycol has an excellent lubricating effect on low-sulfur diesel. This work's findings open opportunities for other researchers to develop alternative lubricating bio-additives for low-sulfur diesel through the in-depth study of tribochemistry or tribosurface.

A facile and modified hydrothermal method was reported for the simultaneous reduction and functionalization of graphene oxide without any reductant. The lubrication mechanisms of nanomaterials were analyzed based on tribological experiments and molecular dynamic simulation. Tribological studies indicated that triethanolamine functionalized graphene oxide exhibited excellent friction-reducing performance and the optimal concentration was 0.15 wt.%, while 0.25 wt.% of triethanolamine functionalized graphene oxide showed best wear resistance in the pin-on-disk experiment. An anti-wear and friction-reducing coefficient τ was proposed to evaluate the tribological properties of lubricants for a uniform standard. Molecular dynamics simulation results revealed the influence of different functional groups on the anti-wear and friction-reducing performance. The sliding distance between graphene oxide layers with COOH functional groups was the longest, it was conducive to reduce the friction coefficient but decrease the wear life. The order of diffusion coefficients of graphene oxide containing different functional groups was DCOOH (4.02 × 10–11 m2 s−1) > DC-OH (1.42 × 10–11 m2 s−1) > DC–O–C (5.24 × 10–12 m2 s−1). It was proposed and verified that the structure of graphene oxide could be optimized by grafting triethanolamine molecules on the C–O–C functional groups to ameliorate the tribological properties.
