There are two sets of coils in the usual CFMoto EFI Ignition Coil, the primary coil and the secondary coil. The primary coil uses a thicker enameled wire, usually about 0.5-1mm enameled wire around 200-500 turns; the secondary coil uses a thinner enameled wire, usually about 15000-25000 turns of about 0.1mm enameled wire. One end of the primary coil is connected with the low-voltage power supply (+) on the vehicle, and the other end is connected with the switch device (breaker). One end of the secondary coil is connected with the primary coil, and the other end is connected with the output end of the high-voltage line to output high-voltage electricity.


The reason why the CFMoto EFI Ignition Coil can turn the low voltage on the car into high voltage is because it has the same form as an ordinary transformer. The primary coil has a larger turns ratio than the secondary coil. But the working mode of the ignition coil is different from that of the ordinary transformer. The working frequency of the ordinary transformer is fixed at 50Hz, also known as the power frequency transformer, while the ignition coil works in the form of pulse, which can be regarded as a pulse transformer. It depends on the engine. The rotation speed repeatedly stores and discharges energy at different frequencies.


When the primary coil is connected to the power supply, a strong magnetic field is generated around the iron core as the current increases; when the switch device disconnects the primary coil circuit, the magnetic field of the primary coil decays rapidly, and the secondary coil A very high voltage will be induced. The faster the magnetic field of the primary coil disappears, the greater the current when the current is disconnected, and the greater the turns ratio of the two coils, the higher the voltage induced by the secondary coil.
