测量了1-丁烯在1.2，4.0，16.0atm压力下，在1000-1700 K温度范围内，当量比为0.5，1.0和2.0时，在反射激波后的点火延迟时间。结果表明，点火延迟时间与温度、压力、当量比和燃料浓度之间存在典型的阿氏关系。从实验数据中推导出了一个关联式。将该关联式与以往的数据进行了比较，取得了较好的一致性。三种广泛使用的模型，NUIG Aramco Mech 1.3（Metcalfe等人，2013）、USC Mech 2.0（Wang等人）和LLNL C4（Marinov等人，1998）模型，对点火延迟时间进行了预测，并与实验数据进行了比较。这些模型都不能很好地再现1-丁烯的实验数据，特别是在较低的温度。此外，在相同的氩氧稀释比（D）下，对碳四烃和1-烯烃的碳双键、碳键和碳链长度的影响进行了对比研究和定性分析。通过灵敏度分析确定了控制1-丁烯着火的关键反应，并提出了改进模型性能的建议。
Ignition delay times of 1-butene were measured behind reflected shock wave at the pressures of 1.2, 4.0, 16.0 atm, in temperature range of 1000–1700 K and equivalence ratios of 0.5, 1.0 and 2.0. Results show that ignition delay times exhibit the typical Arrhenius dependence on temperature, pressure, equivalence ratio and fuel concentration. A correlation was deduced from the experimental data. Comparison was made between the correlation and the previous data, and good agreement was achieved. Three widely used models, NUIG Aramco Mech 1.3 (Metcalfe et al., 2013), USC Mech 2.0 (Wang et al.) and LLNL C4 (Marinov et al., 1998) model, were used to predict the ignition delay times and comparison was made with the experimental data. None of these models can well reproduce the experimental data of 1-butene especially at lower temperature. Besides, comparative studies and qualitative analysis between C4 hydrocarbons and 1-alkenes with respect to the effect of Cdouble bondC bond and the carbon chain length were made at same argon–oxygen dilution ratios (D). Sensitivity analysis was made to identify the key reactions that control the ignition of 1-butene, and modifications for improving the model performance were recommended.
