The role of automobile ignition coil

by:Haiyan     2020-05-17
Is the role of ignition coil power supply 12 v low voltage DianZhuan into 15 ~ 20 kv high voltage. Ignition coil according to the presence of additional resistance can be divided into with additional resistance and with no additional resistance. According to the shape of iron core can be divided into open magnetic circuit and closed magnetic circuit. According to the functional differences, divided into normal and high energy type. Principle is: the dc low voltage inverter, voltage doubling rectifying, into a dc high voltage, and then by controlling the high voltage interruption through the ignition coil primary, secondary induction in ignition coil high pressure ( Generally in 20 kv) Or so, drive discharge ignition spark plug.
