“…However, the desulfurization process of fuel removes some of the polar bonds that are useful for their lubricating properties. The removal of polar compounds will even significantly deteriorate the lubricity of ultra-low sulfur diesel [4], which will cause a large number of problems, including excessive and rapid wear of the fuel pump, fuel injection nozzle corrosion, complex engine start-up, engine instability, insufficient engine power, and shortened life span of the engine [5].…”

Poor lubrication performance of low-sulfur fuel leads to increased wear of diesel engine components. In order to improve the lubrication properties of low-sulfur fuel, we successfully prepared graphene lubricant additives by dielectric barrier discharge plasma-assisted ball milling. The tribological properties of graphene lubricant additives in two types of 0# diesel oils with different sulfur content were evaluated by high-frequency reciprocating rig (HFRR). The results indicated that the expanded graphite was exfoliated and refined into graphene sheets with nine layers by the synergistic effect of the heat explosive effect of the discharge plasma, the impact of mechanical milling function, and the cavitation effect of 0# diesel oil. The organic functional groups of 0# diesel oil were successfully grafted on the surface of graphene sheets. The addition of 0.03 wt % graphene resulted in 20% reduction in the friction coefficient (COF) and 28% reduction in wear scar diameter (WSD) compared to pure 0# diesel oil with a sulfur content of 310 mg/kg. The addition of 0.03 wt % graphene resulted in 24% reduction in the friction coefficient (COF) and 30% reduction in wear scar diameter (WSD) compared to pure 0# diesel oil with a sulfur content of 1.1 mg/kg. The formation of graphene tribofilm on rubbing surfaces improved the lubrication properties of low-sulfur fuel.

“…In general, the lubricious molecules improve lubricity by making solid interactions between the moieties and negatively charged contacting metallic surfaces, enhancing tribo-film growth and preventing metallic surface contact, leading to a lower friction and surface wear [21,23]. It is confirmed that an increase in the chain length and the presence of the unsaturated compounds improve the lubricity of alcohols [19].…”

“…The tribological performance can be categorised into boundary lubrication, mixed lubrication and hydrodynamic lubrication. Fuel lubrication is usually visible at the boundary lubrication regime, where lubricated films are thin and require the formation of a protective tribofilm to eliminate the frictional forces and surface wear [23].…”

Tribological Performance of Biomass-Derived Bio-Alcohol and Bio-Ketone Fuels

This study relates to developing future alternative fuels and focuses on the effects of a fuel’s molecular structure on its properties and performance in advanced propulsion systems. The tribological performance of various biomass-derived oxygenated alternative fuels, including butanol, pentanol, cyclopentanol, cyclopentanone, and gasoline and their blends with diesel, was investigated. Lubricity tests were conducted using a high-frequency reciprocating rig (HFRR). Cyclopentanone-diesel and cyclopentanol-diesel blends result in smaller wear scar sizes compared to using their neat forms. A lower steel disc contaminated with the alternative fuels during the HFRR tests resulted in worn surface roughness values lower than those of the neat diesel by up to 20%. It is believed that these reductions are mainly due to the presence of the hydroxyl group and the carbonyl group in alcohols and ketones, respectively, which make them more polar and consequently helps the formation of the protective lubrication film on the worn moving surfaces during the sliding process. Overall, the results from this study indicate that environmentally friendly cyclopentanol and cyclopentanone are practical and efficient fuel candidates for future advanced propulsion systems.
