Abstract

This study represents studying the production of biodiesel from castor oil and the effect of biodiesel/diesel mixing ratio on diesel engine performance and emissions. The in-situ method used to produce biodiesel from castor oil, Transesterification reaction was studied at a different molar ratio of methanol: oil from 6:1, 1:6.5, 1:7, 1:9, 1:12 to 15:1, at 65 °C, reaction time up to 120 minutes and the mass ratio of catalyst to oil equal 1%. All properties of biodiesel were identical to the ASTM standard. As for the process of separating glycerol from biodiesel. The results showed that the use of a mixer reduced the separation time to 2 hours. Fuel blends with 5% to 20% of castor oil biodiesel in diesel oil were tested, varying engine load from 20% to 80% of engine power. the exhaust concentrations was evaluated and The results showed, (CO) emissions was decreased by nearly 3.34% to 13.79 %, biodiesel decreased (HC) emissions by 5.32% to 21.3%, (HCl) emissions decreased by 10.04% to 40.21% , (O3) emissions decreased by 34.72% to 82.87%, (Cl) emissions decreased by 4.75% to 30.12%, (PM) emissions decreased by 8.5% to 34.76% and (NOx) emissions increased by 0.97% to 3.7% when diesel fuel blends containing 5% to 20% of biodiesel respectively in comparison with diesel fuel.
