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 4倍左右
The use of gasoline ignition coil secondary voltage to gasoline charge is to improve gasoline atomization, energy saving and emission reduction of a new attempt. In this paper, the basic principle of gasoline charge splitting is analyzed in detail. The ignition coil secondary voltage is used as the pulse power and the tip electrode direct charge technology is used. The YSC 1 moving particle transient laser hologram Instrument, shot the gasoline with charge atomization and non-charge atomization of the particle hologram, and the use of self-compiled software for particle image processing and particle size distribution statistics, the statistical results show that the gasoline charge atomized particles relative unloaded Electrospray particle size reduced by about 4 times
