The initiation and combustion of propane-oxygen (P₀ = 1 atm) are experimentally studied by using multispark discharges (ranging from 1 to 9 in number), which are differently located in the cylindrical chamber 72 mm in diameter and 4 mm high. The methods of synchronous recording and measurements of parameters of force pulses with 26 s resolution piezodynamometer were used in the studies. It was shown that for identical gas charges, the duration of generation of force pulses decreases by 30 % as the number of initiation sparks rises in comparison to one-spark initiation in the center of the chamber.

封闭空间内丙烷燃烧的多火花引发

丙烷氧的引发和燃烧（P ₀ = 1 atm）通过使用多火花放电（数量从 1 到 9）进行了实验研究，这些放电在直径 72 毫米和 4 毫米高的圆柱形腔室中的位置不同。研究中使用了26秒分辨率压电测力计同步记录和测量力脉冲参数的方法。结果表明，对于相同的充气量，与燃烧室中心的单火花引发相比，随着引发火花数量的增加，产生力脉冲的持续时间减少了 30%。
