During past five decades, the energy requirement has been mounting steadily and researchers believe that this will increase with time. Therefore, the amount of harmful emission gases will increase and cause global warming. In this study, we have green synthesized Fe3O4 NPs from waste Ziziphus mauritiana seeds and utilized these NPs to improve the jojoba methyl ester blend properties. The chemical and physical properties of jojoba methyl ester have indicated improved potential for using it as an alternative fuel. Firstly, blending of jojoba methyl ester with diesel has proved an effective method for reducing the engine problems associated with the high viscosity of jojoba oil. On the basis of viscosity and calorific value, B15 (1.95 cp and 42.62 MJ/kg) found to be the best blend which was further modified using Fe3O4 NPs as nanoadditives in different concentration (NP10, NP20, NP30, NP40, and NP50). Secondly, engine performance and harmful gas emissions were evaluated for the use of modified jojoba methyl esters with Fe3O4 NPs. The results showed continuous increase in generated power, brake thermal efficiency and decreased concentration of released NOx, CO, HC and soot showed the suitability of Fe3O4 NPs additive jojoba methyl ester blend as an alternative fuel for diesel engine.
