Abstract

Alternative fuels for diesel engines are essential to reduce greenhouse gas emissions, improve energy security by reducing dependence on petroleum, and minimise air pollution by using cleaner-burning fuels. This study investigates the environmental effects of utilising biodiesel derived from waste mosambi peel oil as a sustainable fuel alternative for common rail direct injection diesel engines. Butylated hydroxytoluene (BHT) nanoparticles were employed as an ignition enhancer to mitigate the emissions. The test fuels comprised conventional diesel, mosambi waste peel biodiesel (MWPB), and MWPB blends with BHT [MWPB + 10-µm BHT 10 ppm (parts per million) and MWPB + 20-µm BHT 10 ppm]. The test results indicated that the MWPB + 10-µm BHT 10 ppm blend significantly reduced primary pollutants, with smoke, hydrocarbon and carbon monoxide emissions by 42.3%, 38.09% and 61.71%, respectively, compared to pure diesel. Utilising MWPB resulted in a substantial 14.67% increase in nitrogen oxide emissions at maximum brake power. This study emphasises the potential of waste-derived biodiesel to substantially minimise environmental emissions, encouraging a more sustainable energy future.

期刊介绍： Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
