What is the role of automotive ignition system?

The role of the ignition system is in accordance with the working order of the cylinders regularly in the spark plug between the two electrodes to produce sufficient energy of the electric spark, the ignition system to produce the secondary voltage must be higher than the breakdown voltage, in order to make the spark plugs jumping, the spark plug electrode breakthrough and produce sparks when the voltage required is called the breakdown voltage. Breakdown voltage of the size of the factors affecting: 1, the spark plug electrode gap, the higher the breakdown voltage, electrode tip angular, the required breakdown voltage is low; 2, the greater the pressure of the mixture, the lower the temperature, the higher the breakdown voltage; 3, the higher the temperature of the spark plug electrodes, electrodes around the gas density is smaller, the lower the breakdown voltage.
