在一个球形容器中，在扩展的等效比范围内，在室温和0.3-1.0bar的不同初始压力下，实验研究了气体丙烯-空气混合物在自身废气存在下爆燃过程中的压力-时间演变。闭式容器爆炸的特征参数（峰值压力、最大压力上升速率、达到峰值压力所需时间、爆炸指数）与燃料/氧气比和废气浓度有关。用测量的可燃性参数和绝热爆炸压力和绝热火焰温度的计算值来考察废气的燃烧效果。
The pressure–time evolution during the deflagration of gaseous propylene–air mixtures in the presence of their own exhaust gas was experimentally investigated in a spherical vessel, over an extended range of equivalence ratios, at room temperature and various initial pressures within 0.3–1.0bar. The characteristic parameters of closed vessel explosions (peak pressure, maximum rate of pressure rise, time necessary to reach the peak pressure, explosion index) are examined in connection with the fuel/oxygen ratio and with exhaust gas concentration. The measured flammability parameters together with the computed values of adiabatic explosion pressures and adiabatic flame temperatures are used to examine the inerting effect of exhaust gas.
