Experimental results show that with given double swirl and direct pneumatic-valve and detonation tube structure, the decrease of partial detonable mixture filling proportion causes a little decrease of the peak value of detonation waves' pressure ,but impulse per unit volume of detonable mixture increases linearly.

研究结果表明，在气动阀选定、爆震管长度和爆震管内部结构一定条件下，随着脉冲爆震发动机可爆混气充填爆震管比例的降低，虽然爆震波压力峰值略有下降，但是，单位体积可爆混气获得的冲量线性增加，提高了脉冲爆震发动机的工作性能。

It is dimensioned such that it can guarantee adequate performance over the fill engine speed range.

然而汽车的使用条件是千变万化，这样势必造成发动机的冷却不足或者过度冷却，从而对发动机造成过早损害。
