Overview of Automotive Ignition Coil
With the development of automotive gasoline engines towards high speed, high compression ratio, high power, low fuel consumption, and low emissions, traditional ignition devices are no longer suitable for use requirements. The core components of the ignition device are the ignition coil and switch device. By increasing the energy of the ignition coil, the spark plug can generate a spark with sufficient energy, which is the basic condition for the ignition device to adapt to modern engine operation.
Introduction to ignition coil
With the development of automotive gasoline engines towards high speed, high compression ratio, high power, low fuel consumption, and low emissions, traditional ignition devices are no longer suitable for use requirements. The core components of the ignition device are the ignition coil and switch device. By increasing the energy of the ignition coil, the spark plug can generate a spark with sufficient energy, which is the basic condition for the ignition device to adapt to modern engine operation.
The reason why the ignition coil can convert low voltage electricity in the car into high voltage is because it has the same form as a regular transformer, with the primary coil having a larger turns ratio than the secondary coil. But the working mode of the ignition coil is different from that of ordinary transformers. The working frequency of ordinary transformers is fixed at 50Hz, also known as power frequency transformers, while the ignition coil works in the form of pulses, which can be regarded as pulse transformers. It repeatedly stores and discharges energy at different frequencies according to the different speeds of the engine.
When the primary coil is powered on, a strong magnetic field is generated around it as the current increases, and the iron core stores magnetic field energy; When the switch device disconnects the primary coil circuit, the magnetic field of the primary coil rapidly decays, and the secondary coil will induce a high voltage. The faster the magnetic field of the primary coil disappears, the greater the current at the moment of current interruption, and the larger the turn ratio between the two coils, the higher the voltage induced by the secondary coil.
