Biodiesel is an oil which is extracted from the seeds and nuts of vegetables then blended with diesel. This biodiesel is used for transportation fuel. But these organic fuels easily react with oxygen. Due to this reaction, it is transformed into crystal-like formation. This kind of fuel is not suitable for the engine. So, this paper is focused on improving the oxidation stability of rice bran biofuel along with analyzing diesel engine characteristics. The performance outcomes expressed that rice bran biodiesel gave favorable brake thermal efficiency and minor brake specific fuel consumption. Moreover, the HCs, COx, and NOx emissions decreased as load increased as compared with diesel. From the outcomes, B20 + 1500 ppm showed optimum oxidation stability as 7.35 h. At peak load, B20 + 1500 ppm showed BTE and BSFC were 32.04% and 0.27 kg/kW-hr respectively.

摘要

Biodiesel is an oil which is extracted from the seeds and nuts of vegetables then blended with diesel. This biodiesel is used for transportation fuel. But these organic fuels easily react with oxygen. Due to this reaction, it is transformed into crystal-like formation. This kind of fuel is not suitable for the engine. So, this paper is focused on improving the oxidation stability of rice bran biofuel along with analyzing diesel engine characteristics. The performance outcomes expressed that rice bran biodiesel gave favorable brake thermal efficiency and minor brake specific fuel consumption. Moreover, the HCs, COx, and NOx emissions decreased as load increased as compared with diesel. From the outcomes, B20 + 1500 ppm showed optimum oxidation stability as 7.35 h. At peak load, B20 + 1500 ppm showed BTE and BSFC were 32.04% and 0.27 kg/kW-hr respectively.
