在汽车蓄电池点火系统中,点火线圈将低压电能转换为高压电能,击穿火花塞放电间隙,点燃发动机汽缸内的混合汽体,从而使发动机转动,其性能好坏直接影响着汽车的动力性。影响点火线圈性能的主要参数是:初级线圈电感L_1,初级回路电阻R_1,初级线圈电阻R_(w1),附加电阻R_o,匝比W_2/W_1,压流比最大值K_(Amax),次级电压U_2等。但是,要设计一个高性能,低成本的点火线圈,就必须进行大量繁复的计算,从中分析比较出满足技术指标的最
In the automobile battery ignition system, the ignition coil converts the low-voltage electric energy into high-voltage electric energy, penetrates the spark plug discharge gap, ignites the mixed gas in the engine cylinder, thereby rotating the engine, and the performance of the ignition coil directly affects the dynamic performance of the automobile. The main parameters affecting the performance of the ignition coil are: the primary coil inductance L_1, the primary loop resistance R_1, the primary coil resistance R_ (w1), the additional resistance R_o, the winding ratio W_2 / W_1, the maximum pressure flow ratio K Amax, U_2 and so on. However, to design a high-performance, low-cost ignition coil, it is necessary to carry out a large amount of complicated calculations to analyze and compare the most satisfactory technical indicators
