In this study the use of Chlorella vulgaris biodiesel blends are tested in a naturally aspirated dual fuel diesel engine with various load conditions at a rated speed of 1500 rpm. In the engine, the test fuels such as B20 injection, B20 blending and diesel were prepared and tested. The combustion characteristic has provided a better understanding of the operation of the engine in dual-fuel mode. The combustion analysis was done at the injection timings of 23° angle before top dead centre with an injection pressure of 220 bars. The results show that 20% blend of Chlorella vulgaris microalgae biodiesel with 80% diesel produced higher cylinder pressures, heat release rate, lower combustion duration, and ignition delay as compared to diesel fuel. The experimental outcomes indicate that the usage of algae oil blend in diesel engine is a feasible option.

柴油机中使用第三代生物燃料的燃烧分析

在这项研究中，小球藻生物柴油混合物的使用在自然吸气双燃料柴油发动机中以各种额定转速1500 rpm的负载条件进行了测试。在发动机中，准备并测试了B20喷射，B20混合燃料和柴油等测试燃料。燃烧特性使人们对双燃料模式下的发动机运行有了更好的了解。燃烧分析是在上止点之前的23°角的喷射正时进行的，喷射压力为220 bar。结果表明，普通小球藻的含量为20％与柴油相比，含80％柴油的微藻生物柴油可产生更高的气缸压力，放热率，较低的燃烧持续时间和点火延迟。实验结果表明，在柴油发动机中使用海藻油混合物是一种可行的选择。
