Abstract

Biodiesel as a renewable alternative energy produced from vegetable and animal oils can be used as a fuel for diesel engines. However, biodiesel has a high viscosity that affects the performance of the pump, thereby reducing diesel engine performance. One of the ways to overcome this problem is by preheating the fuel. The purpose of this study is to investigate fuel spray pattern and pump performance including capacity, head, and efficiency at various biodiesel/diesel blends (B0-B30) and preheating temperatures of B30 (30°C-70°C) at constant injection pressure. The results showed that pump performance decreased with increasing percentage of biodiesel. The weakest pump performance occurred at B30. Fuel spray pattern did not change too much, except for B30 where the spray angle decreased significantly. Better results were obtained when biodiesel blend of B30 was heated. The highest pump capacity and efficiency occurred at 50°C, while the highest pump head was at 70°C. At 60°C and 70°C, pump experienced an excessive vibration. Fuel spray angle also increased as the preheating temperature rises. The widest spray angle occurred at fuel preheating temperature of 70°C.

生物柴油/柴油混合物及温度对单缸柴油喷射泵性能及喷射模式的影响

生物柴油作为一种由植物油和动物油生产的可再生替代能源，可以用作柴油发动机的燃料。然而，生物柴油的粘度高，会影响泵的性能，从而降低柴油发动机的性能。克服这个问题的方法之一是预热燃料。本研究的目的是研究在恒定喷射压力下，在各种生物柴油/柴油混合物（B0-B30）和B30（30°C-70°C）的预热温度下的燃油喷射模式和泵性能，包括容量、扬程和效率。结果表明，随着生物柴油添加量的增加，泵的性能下降。泵性能最弱的出现在B30。燃油喷射模式没有太大变化，除了B30，喷射角度显著降低。当B30的生物柴油混合物被加热时，获得了更好的结果。最高泵容量和效率出现在50°C，而最高泵压头出现在70°C。在60°C和70°C时，泵出现过度振动。燃油喷射角度也随着预热温度的升高而增加。最宽的喷射角度出现在燃油预热温度为70°C时。
