Abstract :This study examines the production of biodiesel from cottonseed oil, focusing on its use in diesel engines. The biodiesel was produced through transesterification using sodium hydroxide as a catalyst and methanol as the alcohol, with different fuel blends created by mixing it with diesel fuel. Some blends also included nano manganese dioxide (MnO₂). The properties of the biodiesel, including kinematic viscosity, flammability point, and cetane number, showed improvements with MnO₂ addition, while low temperature filterability limit, pour point, and freezing point decreased. The calorific value was lower compared to diesel, and the addition of MnO₂ did not significantly impact it. SEM analysis revealed MnO₂ nanoparticles with enhanced catalytic properties, which may improve biodiesel performance and reduce emissions. Overall, the study highlights the potential of cottonseed oil biodiesel and the role of MnO₂ nanoparticles in enhancing fuel properties and engine performance.
