摘　　要：利用汽油机点火线圈次级电压使汽油荷电是改善汽油雾化、节能降排的一种新尝试。本文详细分析了汽油带电荷分裂的基本原理 ,使用点火线圈次级电压作为脉冲电源 ,采用尖端电极直接荷电技术 ,在发动机气道稳流试验台上用YSC 1型运动粒子瞬态激光全息测试仪 ,拍摄了汽油带电荷雾化和不带电荷雾化时的粒子全息图 ,并利用自编软件进行粒子图像处理和粒径分布统计 ,统计结果证明汽油荷电雾化后的粒子相对未荷电雾化的粒子其粒径约减少It is a new method for automobile to make petrol electrized to improve atomization and economize fuel & reduce emissions.This paper analyses the basic principle of electrostatic dispersion of petrol,uses secondary voltage of engine ignition coil as pulsating power supply and uses a sharp electrode to make petrol electrized. Holography of petrol carrying charge and petrol not carrying charge are gained by using YSC?1 model moving particle instantaneous laser holography tester at engine air channel experimental table.By designing special software to deal with the picture and count petrol drop radium,it is concluded that the average petrol drop radium of carrying charge decrease about four times than that of not carrying charge.
