| Popis: | In this study, we compared three different blended (20/80 by vol .) biodiesels of rice bran, neem, and cottonseed oils with varying degree of unsaturation. All three biodiesel blends decreased the brake thermal efficiency and increased the exhaust gas temperature of a single-cylinder diesel engine. They decreased CO, hydrocarbon, and smoke emissions, but increased NO x emissions. The biodiesels provided better combustion characteristics than diesel. Of all the tested biodiesel blends, rice bran oil biodiesel decreased CO and hydrocarbon emissions the most, albeit at the cost of increasing NO x emissions. CO, HC, and smoke emissions decreased with the increase in degree of unsaturation, whereas NOx emissions increased with the increase in degree of unsaturation. |
