“…According to the review by Soudagar et al [11], many findings support the addition of metal-based nano-additive to fuels to enhance its viability, while Sule et al [10] further expanded on the various reports and stated that due to the surface per volume ratio of the nanoparticles as an additive, they exhibit the tendency to creates a better combustion process since they can carry higher oxygenated molecules due to their sizes. Some of the nanoparticles used as an additive in diesel engines include aluminum oxide [12], zinc oxide [13], carbon nanotube [14], titanium oxide [15], cerium oxide [16], graphene oxide [17], and magnesium oxide [18]. Aluminum Oxide nanoparticles, for instance, have been previously tested with varying biodiesel classes at different proportions in ratio.…”

This study concentrates on investigating the impact of hybrid additives of ethanol and butanol with magnetite (Iron oxide nanoparticle) added at 100 ppm each to the biofuels, 10% of the resulting nano-biofuel (5% ethanol and magnetite; 5% butanol and magnetite) was then blended with 90% pure palm oil biodiesel (B100). A single-cylinder Yanmar L70N engine was used in the experiment with the resulting fuel. The engine test results indicated that the addition of magnetite nanoparticles in conjunction with the two biofuels significantly reduced brake-specific fuel consumption (BSFC) up to 15.68% (8.8 gm/kW-hr) compared with B100 (10.4 gm/kW-hr) at peak brake power. The break thermal efficiency (BTE) also improved by 4.26% and 9.71% at tested minimum and maximum brake power, respectively. The emission of hydrocarbon (HC), Carbon Oxide (CO), smoke and nitrogen oxide (NOx) were reduced obviously by 14.45%, 11.98%, 7.25% and 5.77% respectively, compared to pure B100 use at peak load. In general, the application of the dual additive approach of combining biofuels and nanoparticles yields positive results due to the improved surface-to-volume ratio of the nanoparticles and good physicochemical attributes of the biofuels, which enhanced the performance of the B100 fuel; thus, more areas should be exploited in these regards.
