“…Of late the utilisation of biofuels for internal combustion (IC) engines is gaining momentum for environmental and performance reasons. Several studies have reported superior engine performance coupled with reduced tailpipe emissions whilst using biofuel either in neat or blended form, with or without additives (Alruqi et al 2023 ; Anantha Padmanabha and Mohanty 2023 ; Anupong et al 2023 ; Elkelawy et al 2022 ; Jain et al 2023 ; Mohan et al 2022 ; Said et al 2023 ; Shanmuganathan et al 2023 ; Suhel et al 2023 ; Wu et al 2023 ). Experimentation in most of the reported literature has been carried out with mineral-based lubricants (Gupta and Agarwal 2021 ; Mujtaba et al 2020 ; Ramteke and Chelladurai 2020 ).…”

The United Nations Sustainable Development Goals (SDGs) are imperative from the point of view of protecting the environment by employing sustainable options. Considerable research has been carried out in the transportation sector to meet this objective. Here, the influence is assessed of epoxidised gingelly oil methyl ester biolubricant with alumina (Al2O3) nanoparticles on the performance and emissions of a single cylinder 0.66-L capacity direct injection compression ignition engine driven by gingelly B20 biodiesel. Engine tests are carried out with gingelly B20 biodiesel as a fuel, and gingelly methyl ester (B100), epoxidised gingelly methyl ester (B100E), and epoxidised gingelly methyl ester (B100E) mixed with 0.5%, 1.0%, and 1.5% w/w alumina (Al2O3) nanoparticles as the lubricant combinations. The results are compared with baseline B20 biodiesel fuel-mineral lubricant operation. The findings indicate that brake thermal efficiency increases by 8.64% for epoxidised gingelly methyl ester (B100E) with 1.0% w/w alumina (Al2O3) nanoparticle biolubricant in comparison to baseline operation. Considerable reductions in emissions are detected; specifically, reductions of 52.4%, 22.0%, 20.0%, and 34.9%, respectively, are observed for CO, NOx, and HC concentrations and smoke opacity for the abovementioned combination as compared to baseline operation. The present work suggests that further research is merited on green fuel-green lubricant combinations. The findings of this study address the United Nations Sustainable Development Goals (SDGs) 7 and 13.

Fuel lubricity is an essential property that ensures the longevity end efficiency of diesel CI engines. Nanomaterials have been shown to have the potential to improve lubricity in many different lubricating substances, including fuels. Moreover, the combustion process has also been shown to improve with the introduction of nanomaterials. This study investigated a series of nanoparticles, including carbon nanoplates, carbon nanotubes, aluminum oxide, zinc oxide, and cerium oxide, as lubricity-enhancing additives for selected fuels. Conventional diesel fuel and rapeseed oil methyl ester, referred to as biodiesel, were chosen as base fuels for modification. The lubricity was evaluated according to the standard test method ASTM 6079 using the HFRR tribometer. The leading lubricity indicators were the wear scar diameter, wear volume, and coefficient of friction. In addition, the worn surface analysis was performed to elucidate the lubrication mechanism. The results show that the addition of nanoparticles can improve the lubricity of both investigated fuels. However, the effect differed among nanoparticles and fuels. In summary, carbon nanotubes could be a rational choice for both fuels. In addition, zinc oxide improved the lubricity of diesel fuel, while carbon nanoplatelets and aluminum oxide nanoparticles showed improvements in the lubricity of biodiesel.

This study investigates the effects of magnesium oxide (MgO) nanoparticles on combustion performance and emissions in diesel engines. MgO's well‐ordered crystal structure, high thermal stability, and oxygen‐carrying capacity positively influence engine performance. The effects of 50 and 100 mg/L MgO concentrations were compared, showing up to a 5% improvement in brake thermal efficiency at 100 mg/L. Additionally, reductions of 8% in CO and 10% in HC emissions were achieved. MgO's crystal structure contributed to higher combustion temperatures, leading to lower harmful emissions. However, an increase in NOx emissions was observed, indicating the need for careful balancing between performance improvements and emission control. These results highlight MgO as an efficient and environmentally friendly fuel additive.
