Summary:
In this study, the production stages of biodiesel from olive stones and the equipment used in the production process are introduced. Furthermore, the engine performance and exhaust emissions of biodiesel blends obtained from olive stones (B20D80) and its nanoparticle-added derivatives in diesel engines were evaluated. Using test data provided by the PCS engine test system, experiments were conducted with pure diesel (D100), olive stones (BOS20D80), and various additives containing 50 ppm TiO₂ and 50 ppm activated carbon + 50 ppm TiO₂. The experiments revealed improvements in the thermal efficiency of the nanoparticle-added pure diesel and BOS20D80 fuels, while relatively higher NO emissions were observed.
