The present study involves obtaining biodiesel from freshwater algae biomass. Biodiesel is prepared using the transesterification method. Three types of biodiesel samples are produced using three different alcohols (methanol/ethanol/butanol). The prepared biodiesel samples are tested for their properties by adopting American Society for Testing and Materials (ASTM) standards. A B20 blend of these esters is examined in a compression ignition engine for determining its performance as well as emission characteristics. The results confirmed that the brake thermal efficiency (BTE) values of the biodiesel blends were closer to that of diesel, and its brake specific consumption values were higher. There was a considerable reduction in emissions of CO and UHC for biodiesel blends; their NOx emission values are slightly higher than that of diesel. Out of three esters used, methyl esters show improved performance and emission characteristics.

淡水藻油的甲基,乙基和丁基酯共混物对CI发动机的燃烧,性能和排放的影响

本研究涉及从淡水藻类生物质中获得生物柴油。生物柴油是使用酯交换法制备的。使用三种不同的醇(甲醇/乙醇/丁醇)可生产三种类型的生物柴油样品。通过采用美国材料试验学会(ASTM)标准测试制备的生物柴油样品的性能。在压缩点火发动机中检查了这些酯的B20混合物,以确定其性能以及排放特性。结果证实,生物柴油共混物的制动热效率(BTE)值接近于柴油,并且其制动比消耗值较高。生物柴油混合物的CO和UHC排放量大大减少;他们的NO X排放值略高于柴油。在使用的三种酯中,甲酯显示出改进的性能和发射特性。
