Abstract

The integration of aluminium oxide (Al₂O₃) nanoparticles into B10 biodiesel blends offers a promising approach to improving engine performance and reducing harmful emissions. This study evaluates the effect of Al₂O₃ additives on Brake Thermal Efficiency (BTE), Brake Specific Fuel Consumption (BSFC), and exhaust emissions in a compression ignition engine. Experiments were conducted using calibrated instruments, and uncertainties were considered with a coverage factor of 1.66, yielding an overall error margin of ±2% to ±5%. The B10Al100 blend (B10 with 100 ppm Al₂O₃) demonstrated a 10% increase in BTE over diesel and 16.5% over B10 alone. BSFC improved by approximately 14%, indicating more efficient combustion. Emission results showed a 10.8% reduction in NOₓ for B10Al150 compared to diesel, and 14.5% compared to B10. CO emissions decreased by 32.7% over diesel and 29% over B10, with additional reductions in HC and CO₂ emissions These improvements are attributed to the catalytic activity and high thermal conductivity of Al₂O₃, which enhances atomization, combustion uniformity, and oxidation of pollutants. However, challenges such as nanoparticle stability and NOₓ control remain. Further research is needed to optimize nanoparticle dispersion and validate long-term performance in multi-cylinder engines.

Keywords: Aluminium oxide, Mechanical properties, Polymeric composites, Emission, Performance.
