Abstract The present world faces the crisis of fossil fuels as it will no longer sustain in the future, gives a knowledge to look on waste resources, where waste rice and neem seed are utilizable for the production of biofuels by the process of fermentation and transesterification. In this paper, the physiochemical properties of the produced biofuels are examined. The 5% rice wine alcohol is used as an additive with neem methyl ester-diesel blend to lower the viscosity and flash point for the better performance in the single cylinder compression ignition engine. Different blends as D90B5RW5, D85B10RW5, D75B20RW5, and D65B30RW5 are prepared and examined experimentally by varying the engine loads (0–100%) at constant engine speed (1500 rpm). Experimental results showed the reduction of carbon dioxide (CO2), carbon monoxide (CO), hydrocarbon (HC) and smoke opacity, however oxide of nitrogen (NOx) is found higher. In the performance, D75B20RW5 shows 8% higher brake thermal efficiency and 3.33% lower brake specific fuel consumption compared to diesel. While in the combustion the peak cylinder pressure and net heat release rate are seen to be higher for biodiesel blends with additive.

印楝甲酯-米酒醇-柴油混合燃料四冲程单缸柴油机燃烧、性能及排放分析试验研究

摘要 当今世界面临着化石燃料的危机,因为它在未来将不再可持续,提供了一个认识废物资源的知识,其中废弃稻米和印楝种子可用于通过发酵和酯交换过程生产生物燃料。在本文中,检查了生产的生物燃料的理化特性。5%的黄酒酒精与楝树甲酯-柴油混合用作添加剂,以降低粘度和闪点,以提高单缸压燃发动机的性能。不同的混合物如 D90B5RW5、D85B10RW5、D75B20RW5 和 D65B30RW5 是通过在恒定发动机转速 (1500 rpm) 下改变发动机负载 (0–100%) 来制备和实验检查的。实验结果表明减少了二氧化碳(CO2)、一氧化碳(CO)、碳氢化合物 (HC) 和烟雾不透明度,但发现氮氧化物 (NOx) 更高。在性能上,D75B20RW5的制动热效率比柴油高8%,制动比油耗低3.33%。而在燃烧过程中,与添加剂混合的生物柴油的峰值气缸压力和净热释放率被认为更高。
