摘要
开发了一套超高能点火装置 ,其点火能量比传统火花塞点火系统高 3～ 4个数量级。实验结果表明 :对于超高能放电 ,放电持续时间随着电极放电端面积的增大、电极之间距离的减小、放电电压的增大而缩短 ;超高能放电能扩展稀燃极限 ,在常温常压下将预混合气的过量空气系数扩展 0 6个单位。
A super-high-energy ignition device is designed for the ignition of lean mixture.Its ignition energy is 3 to 4 order higher than that of the traditional ignition system.The duration of electric discharge is reduced with the increase of the electrode section area,the decrease of the distance between electrodes,or the rise of discharge voltage.Moreover,the super-high-energy ignition can also extend the lean-burn limit obviously.Under ordinary temperature and pressure,the excess air ratio of pre-mixture can increase by 0.6.
