Biodiesel Blends: A Sustainable Solution for Diesel Engine Performance Improvement

Recent studies have highlighted the significant potential of biodiesel as a sustainable and environmentally friendly alternative to conventional diesel, which has been in widespread use for decades. This research focused on a detailed experimental analysis of the performance characteristics of a diesel engine using biodiesel blends derived from sunflower, palm, and corn oils. The engine was tested under varying load conditions at a constant speed, with key performance parameters such as torque, brake power, Brake Specific Fuel Consumption (BSFC), brake thermal efficiency, total fuel consumption, and exhaust temperature meticulously recorded and analysed. The results showed that all biodiesel blends outperformed pure diesel in terms of BSFC, exhaust temperature, and brake thermal efficiency, offering clear economic benefits over traditional diesel. Moreover, a significant reduction in nitrogen oxide (NOx) emissions was observed with biodiesel blends, underlining their environmental advantages. These findings add to the growing evidence supporting biodiesel as a viable energy sustainability and environmental protection solution. The study’s outcomes have the potential to shape future policies aimed at reducing carbon emissions and encouraging cleaner combustion technologies in diesel-dependent sectors, marking an essential step toward sustainable energy aligned with global environmental objectives. Major Findings: Biodiesel blends derived from sunflower, palm, and corn oils demonstrated superior performance compared to pure diesel, with enhanced brake thermal efficiency, lower BSFC, and reduced exhaust temperatures. Significant reductions in NOx emissions highlight biodiesel's potential as a sustainable and environmentally friendly alternative to conventional diesel, aligning with global energy and environmental goals.
