Study on initial combustion characteristics of kerosene based on inductive charging ignition system

Spark ignition is an important method to achieve combustion of in-cylinder mixture. The inductive charging ignition is considered to be a simple and effective ignition method. This study presents a circuit simulation model of this ignition system in MATLAB/Simulink and the effects of charging voltage, charging time and multi-pulse charging interval on ignition energy were calculated and the ignition energy value was obtained. The experimental study of the ignition system in a constant volume vessel was carried out to explore the influence of ignition energy on the initial combustion of kerosene. The results show that the simulation results match well with the experimental results. With the increase of ignition energy, the initial flame propagation of kerosene shows speed fluctuations and the higher ignition energy makes the propagation speed of flame fluctuate more obviously.
