Journal Article 2024 04 26 Renewable and cleaner diesel engine fuel has received a lot of attention recently as a result of the depletion of fossil resources. In light of this, biodiesel has proven to be a viable substitute for diesel fuel. The finest B20 Jamun blends were combined with three different types of nano-additives to create Syzygium cumini (Jamun) biodiesel, which was tested in a naturally aspirated diesel engine. Global researchers are increasingly developing novel nano-additives, recognizing them as a promising and effective approach for enhancing fuel properties and engine performance. This technology was combined with different biodiesels. Also included in this chapter is an examination of a test engine using three distinct nano-additives: titanium dioxide (TiO2), zirconium oxide (ZrO2), and cerium oxide (CeO2). These additives were combined to create the best blends of Syzygium cumini (B20), and the results were evaluated based on factors such as performance, combustion, and output emissions. Additionally, a proposal is made to further improve the construction of a realistic and economically feasible nanoparticle addition for diesel and biodiesel fuel. https://rera.shahroodut.ac.ir/article_3653_09f75517ac6e884df14132ad1e870e27.pdf
