常用带有触点的晶体管点火系统,其点火线圈次初级的匝数比必须增大,也就是次级线圈匝数大致不变,初级线圈的匝数减少以减小电感,增大电流上升速率,从而增大初级线圈平均电流、点火线圈输出电压和能量,否则难以达到满意的效果。这种点火系统初级电流较大(4~7安),分电器触点承受不了这么大的电流,因此用大功率晶体管来控制并由分电
Commonly used contact with the transistor ignition system, the ignition coil secondary primary turns ratio must be increased, that is, the number of turns of the secondary coil is generally unchanged, reducing the number of primary windings to reduce the inductance, increasing the current rate of rise , Thereby increasing the average primary coil current, ignition coil output voltage and energy, otherwise it is difficult to achieve satisfactory results. This ignition system, a larger primary current (4 ~ 7 A), distributor contacts can not withstand such a large current, so use high-power transistors to control and by the power distribution
