The development of cars is becoming increasingly rapid and sophisticated. With the advancement of time, traditional ignition devices can no longer meet current demands, hence the emergence of the ignition coil. Today, I will introduce to you the functions of the ignition coil.
As automotive gasoline engines develop towards higher speed, higher compression ratio, greater power, lower fuel consumption, and lower emissions, traditional ignition devices no longer meet usage requirements. The core components of the ignition device are the ignition coil and switch device. By improving the energy of the ignition coil, the spark plug can generate sufficient spark energy, which is the basic condition for the ignition device to adapt to modern engine operation.
Function of the Ignition Coil
The resistor added in the low-voltage circuit of the ignition coil plays a role in balancing the high-voltage spark. When the current passes through the primary coil, a magnetic field will be generated. From the beginning of current input to the saturation of the magnetic field (i.e., reaching the maximum level), it takes a period of time. At low engine speeds, the magnetic field can reach saturation. However, at high engine speeds, due to the shortened time, the magnetic field cannot reach saturation, and the secondary voltage produced will be insufficient, causing the spark to weaken.
