本文針對石油航空燃料（JET A-1、JP-5及JP-8）及混合物（50%柴油及50%JP-5）在恆定體積燃燒室（CVCC）實施點火特性之研究，為了在台灣能實現單一燃料政策之動機，本文操作參數具有總點火延遲時間、冷焰期間點火延遲時間、燃油壓力變化、熱釋放效率，將JP-8設定為主要燃料，將取代JET A-1和JP-5之使用，實驗設定在燃燒室壓力為10、15及20±0.2bar，且在600至818 ±5K之溫度下，各噴射5次所得之平均數進行分析，可獲得總點火延遲時間等相關數據，再與燃料內含烷烴類、異烷類、環烷類、芳香烴類之比例及碳氫比進行比對分析，分析結果，在高溫下總點火延遲及冷焰期間點火延遲時間時間JP-5 > JP-8 > JET A-1，JP-5熱釋放速率（HRR）最小且具有多階段的尖峰值，可能是因為環烷類最多，JP-8熱釋放速率最大，可能是因為異烷類最多，結論是在低溫下，JP-8點火延遲特性略有差異之下，可取代JP-5和JET A-1；在高溫下總點火延遲及冷焰期間點火延遲時間時間JP-5 > 混合物 > 柴油，JP-5比較晚點燃及熱釋放速率最小且具有多階段的尖峰值，可能是因為環烷類(Cyclo-Alkanes)最多，導致較晚點火燃燒，混合物比較早點燃，可能是因為異烷類(Iso-Alkanes)最多，結論是在低溫下，JP-8點火延遲特性略有差異之下，可取代混合物、JP-5和JET A-1。

This study investigated the spray ignition characteristics of petroleum jet fuels (JET A-1、JP-5 and JP-8) and mixed oil (50% diesel and 50% JP-5) using a constant volume combustion chamber. To achieve the motivation of a single fuel policy in Taiwan, the operating parameters in this article include total ignition delay time, ignition delay time during cold flame, fuel pressure change, and heat release rate. For use with JP-5, the experiment is set to the combustion chamber pressure of 10, 15 and 20 ± 0.2 bar, and at a temperature of 600 to 818 ± 5 K, the average of each injection of 5 times is analyzed, and the total ignition can be obtained relevant data such as delay time is compared and analyzed with the ratio of alkanes, iso-alkanes, cyclo-alkanes, aromatic and the hydrocarbon ratio in the fuel. The analysis result shows that the total ignition delay and cold flame ignition delay time at high-temperature( ) JP-5 > JP-8 > JET A-1. The conclusion is that at low-temperature ( ), the ignition delay characteristics of JP-8 are slightly different, which can replace JP-5 and JET A-1; At high-temperature, the total ignition delay and cold flame ignition delay time JP-5 > Mixed oil > Diesel. The conclusion is that at low-temperature, the ignition delay characteristics of JP-8 are slightly different. Below, it can replace mixed oil, JP-5 , and JET A-1.
