Benz Ignition Coil

1. the ignition coil is able to turn low voltage into high voltage on the car, because there is the same form as the ordinary transformer, the primary coil and the secondary coil turns ratio is larger.
2. but the ignition coil working mode is different from the ordinary transformer, the ordinary transformer can work continuously, and the ignition coil is intermittent work, it according to the different speed of the engine at different frequencies for repeated energy storage and discharge. 3. when the primary coil is switched on, with the growth of the current around the generation of a strong magnetic field, the iron core stored magnetic field energy, when the switch device makes the primary coil circuit disconnected, the primary coil magnetic field rapidly attenuated, secondary coil will induce a high voltage.
4. The faster the magnetic field of the primary coil disappears, the greater the current at the moment of current disconnection, the greater the turns ratio of the two coils, the higher the voltage induced by the secondary coil.
