Experiments were designed to study the effect of blends of jojoba oil with diesel fuel on tractor emission characters. Exhaust gases emission tests were conducted for agricultural tractor running on the 0, 20, 40, 60 and 80% jojoba-diesel fuels as compared to pure petroleum diesel fuel under typical field tillage operation at different forward speeds (1.75 , 2.60 and 4.85 km/h). The chemical analysis of Jojoba oil revealed that it contains law carbon atoms and oxygen atoms in its chemical structure, so it produced complete combustion and decreased the emitted toxic gases which lower environmental pollution because it is an oxidizing agent. The increase in jojoba oil blended ratio more than 20% leads to increase fuel viscosity which decreases the engine power and incomplete combustion which leads to increase environmental pollution. The utilization of jojoba-diesel blend 20% (J20) gave significant reduction in total hydrocarbon (THC), carbon dioxide (CO2), carbon monoxide (CO), Sulfur dioxide (SO2) and nitrogenous oxides (NOx) gases emissions, which have positive effect on environment. Using jojoba oil blend 20% (J20) improved the combustion efficiency to 80% at tractor forward speeds, which gave better performance of the tractor engine and decreased emission of toxic gases.
