Types of Auto Ignition CoilThe ignition coil is the core component of the ignition device. When starting, the energy of the ignition coil needs to be increased, and the spark plug can generate sparks with sufficient energy. This is the basic condition for the ignition device to adapt to the operation of modern engines. The ignition coil has an important influence on the starting and safety performance of the engine.There are many types of ignition coils. The ignition coil is mainly composed of primary winding, secondary winding, iron core and shell. Both the primary winding and the secondary winding are wound on the iron core. The number of turns of the primary winding is less, and the working current is larger; the number of turns of the secondary winding is more, and the working voltage is larger, generally above 10000V.According to the magnetic circuit, the ignition coil is divided into two types: open magnetic type and closed magnetic type.The traditional ignition coil is of open magnetic type, and its iron core is made of silicon steel sheets of about 0.3 mm, and the secondary and primary coils are wound around the iron core. The closed magnetic type uses an iron core similar to III to wind the primary coil, and then winds the secondary coil outside, and the magnetic field line is formed by the iron core to form a closed magnetic circuit. The advantages of closed magnetic ignition coils are less magnetic leakage, small energy loss and small size, so closed magnetic ignition coils are generally used in electronic ignition systems.In short, if there will be more subdivisions of Distributor Ignition Coils, please experience it slowly
