摘要：

In order to obtain the low-temperature auto-ignition characteristics of fuel and the promotion effect of the plasma-assisted ignition, based on the rapid compression machine system in the paper, the auto-ignition characteristics of cracked gas of aviation kerosene(29.4%CH4/30.8%C2H6/21.3%C2H4/18.5%C3H6)are experimentally investigated at equivalence ratio 1.0, pressure 3.4MPa and temperature range 877.7~915.9K, and the ignition delay times are obtained.Furthermore, by decoupling of discharge and chemical kinetics, the promotion of non-equilibrium plasma on the cacked gas ignition is studied. The results show that with the increasing of initial temperature from 877.7 to 915.9K, the ignition delay times of cracked gas are shortened from 65.5ms to 8.1ms. And the measured results are basically consistent with the predicted results by revised USC-II mechanism.At the same time, the study shows that the plasma discharge has different degrees of promoting effect on the self-ignition of cracked gas at different temperatures, and the promoting effect is more obvious at low temperature. © 2022, Editorial Department of Journal of Propulsion Technology.
