Abstract: The world's fuel consumption is rising quickly, which has an impact on every nation's economy globally. As a result, every nation is under pressure to develop alternative fuel sources to help cut back or even completely replace the use of petroleum. As a result, switching to other alternative energy sources like biodiesel, biogas, solar energy, wind energy, etc. is necessary. One alternate energy source that can be used in diesel engines without further engine changes is rice bran oil. Our project focuses on the assessment of the effects of crude rice bran biodiesel, and its mixes with diesel on the performance of diesel engines. This work focuses on the engine's performance and exhaust emission characteristics as well as the manufacture of biodiesel from rice bran oil. Primarily, we have taken diesel fuel as the baseline data for the performance and emission analysis. Later, we have chosen to use a variety of biodiesel blends made from rice bran oil. In this experimental project, we used B10, B20, and B30 blends of already-used rice bran biodiesel. The experimental investigation of the blends of used rice bran biodiesel is carried out on a single cylinder 4 stroke diesel engine without making any modification to the diesel engine. The current work explored experimentally the impact of biodiesel blends on the efficiency and emissions of diesel engines when operating under a variety of loads at a constant speed. The experimental analysis shows that rice bran biodiesel bends can be utilized as a fuel in a diesel engine without requiring any modifications to the engine and of all the blends B10 showed the optimum output in terms of performance and emissions than the other two blends.
