摘要

近年來生質柴油在國際間已廣泛被使用，而全球主要植物性油脂的產能和消耗量也都持續上升著。當前為達到柴油引擎節能減碳的目的，低碳生質柴油和氫氣的使用逐漸受到重視。本研究為探討加氫之高低碳兩種生質柴油對柴油引擎的影響，故於實驗結果中發現低碳生質柴油混氫燃料不僅能達到與高碳生質柴油混氫燃料的相同引擎性能，同時低碳生質柴油混氫燃料的能源效率較高碳生質柴油混氫燃料高約2.20%，又在廢氣排放特性的表現上，亦較高碳生質柴油混氫燃料的smoke、NOX和HC濃度以及EGT分別低約68.63%、23.49%和20.95%以及5.43%。

The biodiesel fuels are being used prevalently in recent years; the .production and consumption of major plant-based biodiesel fuels are keeping increase continually in the world.

In order to achieve the objective of energy-saving and carbon-reduction for diesel engines, the utilization of low-carbon biodiesel and hydrogen gas become more important.

This study is discussing the effects of diesel engine which was fueled by high-carbon-link biodiesel and low-carbon-link biodiesel both mixed with hydrogen gas.

By interpreting the experimental results we found that Low-carbon biodiesel mixed with hydrogen gas can reach the same engine performance in diesel engine which is fueled by high-carbon biodiesel mixed with hydrogen gas. Besides, the former fuel can enhance the energy efficiency for 2.2%, considering exhaust emission aspects, the Smoke, NOx, and HC can reduce 68.63%, 23.49% and 20.95%. The EGT(Exhaust Gas Temperature) can also reduce 5.34%.
