The Chlorella sp. biodiesel was produced from the microalgae oil via transesterification process. Three combinations were studied. Blend of biodiesel (20%) with diesel (80%) was prepared and denoted as B20. Then the TiO₂ nanoparticles were added to each B20 blend samples in a quantity of 50 and 100 ppm using an ultrasonicator. In compliance with the American Society for Testing and Materials (ASTM) fuel requirements, the biodiesel blends have been characterized. In an unaltered four-stroke diesel engine using various loads, the biodiesel blends were studied. The experimental outcomes show a decrease in exhaust emissions in terms of CO, HC, NOx, and Smoke.

小球藻的排放分析 柴油机中含氧化物纳米添加剂的微藻生物柴油

该小球藻属。生物柴油是由微藻油经酯交换过程制得的。研究了三种组合。制备了生物柴油（20％）与柴油（80％）的共混物，并表示为B20。然后使用超声仪将TiO ₂纳米颗粒以50和100 ppm的量添加到每个B20共混物样品中。为了符合美国材料试验学会（ASTM）的燃料要求，已对生物柴油混合物进行了表征。在使用各种负载的未改变的四冲程柴油发动机中，对生物柴油混合物进行了研究。实验结果表明，废气排放减少了CO，HC，NOx和烟气。
