Abstract This study extensively examined the impact of aluminium oxide (Al 2 O 3 ) and titanium dioxide (TiO nanoparticles addition in biodiesel fuel derived from Guizotia abyssinica (L.) oil. The assessment blends, which were created by combining was conducted using energy, exergy, sustainability indices. highest recorded power output 2.81 kW observed for GAB20A engine operating at 1800 rpm. experimental results revealed that exhibited lowest consumption, with a value 203 g/kWh, when operated 1600 rpm among all tested blend fuels. level energy efficiency 29.5%, as determined study. Simultaneously, it GAB20 1200 fuels 25%. emission levels nitrogen oxides (NOx) carbon monoxide (CO) to be quite low, although little rise (CO detected. For validation artificial neural network (ANN) used an average 1.703% difference efficiency, 2.246% decrease exergy 1.416% index found.

In this study, an aqueous ammonia emulsion and a zinc sulfide/copper (ZnS/Cu) nanocomposite were blended with algae biodiesel-diesel blend, the optimum levels of parameters identified for enhanced performance reduced emissions. The cultivated concurrently wastewater treatment, biodiesel's properties as well nanocomposite's structural surface morphology analyzed. Response methodology was employed optimization, confirmation tests conducted. results indicate that cultivation effectively removes nutrients, optimal values process determined to be 10% biodiesel, 14% ammonia, 95 ppm ZnS/Cu.

The utilization of nanomaterials in biofuel production has garnered considerable attention owing to their distinctive characteristics, including a high surface-area-to-volume ratio, strong dispersibility, and enhanced reactivity. This review delves into the transformative role played by nanomaterials, specifically graphene-based catalysts, metal-organic frameworks, biomass waste materials, carbon nanotubes, augmenting various facets production. Noteworthy examples include application metal-modified graphene oxide composite incorporating aluminium ferric, revealing significant 25% reduction free fatty acid content remarkable 15% increase methyl hexadecanoic yield. Furthermore, eco-friendly synthesis TiO2 nanoparticles showcased consistently biodiesel yields, reaching 95% over 10 cycles, underscoring its economic advantages stability. However, it is essential acknowledge potential drawbacks associated with nanomaterial Environmental concerns, such as nanoparticle release during processes impact on ecosystems, well safety issues related exposure nanoparticles, require careful consideration. comprehensive overview encompasses recent studies green synthesis, hydrothermal-assisted carbonization, gold hydrolysis, nano-fuel technology engine characteristics. Innovations catalysts processes, sulfonic functionalized frameworks magnetic MOF-derived are scrutinized for sustainability. culminates thorough analysis environmental impacts, accentuating both benefits challenges entailed seamless integration nanotechnology

In modern society where fossil fuel prices are increasing and environmental issues becoming more severe, biodiesel, as a new type of clean fuel, is receiving attention. Biodiesel has the advantages renewability, friendliness, good properties, demonstrating broad application prospects. However, use biodiesel also faces some challenges, such higher density kinematic viscosity, lower calorific value, etc. The nanoparticles in engines helps to achieve goal fuel. terms characteristics, increase cetane flash point improving combustion efficiency safety, but may affect combustion. can promote micro explosions secondary atomization improve cylinder pressure, heat release rate, brake thermal while reducing consumption. Nanoparticles reduce HC CO emissions, through oxygen reaction area, incomplete products. On contrary, CO2 emissions because better conditions oxidation reactions. For NOX temperature others emissions. Comparison shows that all offer varying degrees improvement engine performance provided by TiO2 significantly than other nanoparticles. future, synergistic effect multiple should be explored further achieving effects cannot achieved single nanoparticle.
