汽车火花塞电流方向分析

Analysis of current direction of automobile spark plug

汽车点火系统中,高压缸线中的电流方向,是一个有争议的问题。文章从高中物理的角度出发,根据右手螺旋定则、法拉第电磁感应定律、带点离子在电场中的运动原理,对火花塞电流进行了分析,得出电流从接地电极到中心电极流动的结论。

The direction of the current in the high-pressure cylinder line is a controversial issue in the automotive ignition system. From the point of view of high school physics, according to the right-handed spiral rule, Faraday＇s law of electromagnetic induction, and the principle of motion of point ion in electric field, this paper analyzes the spark plug current, and draws the conclusion that the current flows from the ground electrode to the center electrode
