Ignition coil Technology
According to magnetic circuit,ignition coil is divided into two types: open magnetic type and closed magnetic type. The traditional ignition coil uses the open magnetic type. The iron core is laminated with silicon steel sheets,which is about 0.3 mm, then secondary and primary coils are wound on the iron core. The closed magnetic type uses a field-like iron core to wind the primary coil, and the secondary coil is wound outside. The magnetic line of force is formed by the iron core to form a closed magnetic circuit. The advantages of closed magnetic ignition coils are less magnetic leakage, low energy loss, and small size. Therefore, closed magnetic ignition coils are commonly used in electronic ignition systems.
