Environmental Assessment of Diesel Engine Performance using Neem Biodiesel Blended with Al2O3 Nanoparticles
Main Article Content
Abstract
This study examines the performance, combustion characteristics and environmental impact of Neem biodiesel blends (B10, B20, B30) enhanced with 50 ppm Al₂O₃ nanoparticles in a 3.5 kW single-cylinder stationary diesel engine, compared to conventional diesel. The addition of Al2O3 nanoparticles notably improved combustion efficiency and reduced emissions. The results revealed a slight decrease in Brake thermal efficiency (BTE), with reductions of 5.8% for B10, 3.1% for B20, and 4.5% for B30 compared to diesel, while Specific Fuel Consumption (SFC) increased by 12.5%, 4.2%, and 9.8%, respectively. The environmental performance showed significant benefits, including a 26.7% reduction in carbon monoxide (CO) emissions, a 35.4% reduction in hydrocarbon (HC) emissions and an 18.9% lower smoke opacity for B30. However, concentration of nitrogen oxide (NOx) emissions increased by 21.8% for B30 in comparison to diesel. These findings underscore the potential of Neem biodiesel blends, particularly when enhanced with Al₂O₃ nanoparticles, as a sustainable alternative fuel.
