Experimental studies were conducted to investigate the effects of driving parameters,such as driving voltage and negative demagnetizing pulse,on the dynamic response performance of a three-way solenoid valve in the common-rail fuel injection system.

结果表明：提高驱动电压可以有效地提高三通电磁阀的动态响应性能；在不同驱动电压下，对于同一正向励磁脉冲都有一个最优的反向消磁脉冲，这时三通电磁阀的动态响应特性最好；驱动电压越高，最佳消磁脉冲越小，最佳消磁脉冲变化越缓慢。

On the basis of experiment analyses we would got that, When arc met with chute, it was blocked and had a stagnation, this made hot gas flow incrase near the chute; After arc went into the chute, mental vapor from arc root would lower the dielectric strength near the chute, meanwhile, High value of arc voltage and the corase face of the chute made electric strength increase. These factors might give rise to local restriking near the chute, and made arc voltage drop suddenly.

总结实验结果并加以分析，本文提出了这样的观点：电弧进入栅片时，在入口处受阻后的停滞，会使该区域的热气流增加；进入栅片后，弧根蒸发的金属蒸汽、电弧热气流会降低栅片入口区域的介质强度；电弧被栅片分割后，电压急剧上升，再加上栅片表面的不均匀会使局部区域的电场强度显著增加，这些因素的综合作用会导致电弧在栅片入口附近发生局部重击穿，引起电弧电压电压跌落。
