Products description
In the automobile ignition system, it can convert the battery voltage (12v) into the high voltage required for the ignition and combustion of the spark plug.
With the development of automobile gasoline engines in the
direction of 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 the switch device. By
increasing the energy of the ignition coil, the spark plug can
generate a spark with sufficient energy. This is the basic
condition for the ignition device to adapt to the operation of
modern engines.
There are two sets of coils in the usual 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 0.1mm enameled wire around 15000-25000 turns. One end of the primary coil is connected to the low-voltage power supply (+) on the vehicle, and the other end is connected to 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.
