The ignition coil
It is one of the key parts of engine ignition device, which provides sufficient energy for spark plug to generate enough electric spark and improve engine performance.
The ignition coil is mainly composed of primary coil, secondary coil and core.
According to the magnetic circuit, the ignition coil is divided into two types: open magnetic type and closed magnetic type.
Closed magnetic type, the use of the shape of core around the primary coil, and then around the secondary coil, the magnetic field lines composed closed magnetic circuit core.The advantages of closed magnetic ignition coil are less magnetic flux leakage, small energy loss and small volume. Therefore, closed magnetic ignition coil is widely used in electronic ignition systems.
