Performance Evaluation of Rice Bran and Moringa Blended Biodiesel in CI Engine

摘要

Biofuels are taken to a notable option for research to energy sources because of their beneficial effect to milieu. In this study, two potential sources namely; Moringa and Rice bran oils are investigated critically as potential sources for biodiesel production. The work was classified into some steps. Firstly, biodiesel production from the two feedstock, secondly, measure the important physicochemical properties of biodiesels, and finally engine test is carried out with biodiesel-diesel blends under constant torque with variable speed. The results show that with the increasing speed, BSFC increases for both biodiesel blends and diesel and biodiesel blends shows only about 2% more BSFC than diesel. Exhaust temperature of biodiesel is about 5-8% higher than diesel but this difference is decreasing with increasing speed. It can be concluded that rice bran and moringa oil would be the feasible option for biodiesel as they satisfy ASTM standard limit and their performance is nearly similar to diesel.
