It is divided according to the electrode material, such as nickel gold, silver alloy, yttrium gold, platinum, iridium gold, double iridium gold , platinum iridiumSpark plugetc., the lifespan is 20,000. It varies from 150,000 kilometers to 150,000 kilometers.
The working principle of the spark plug is high voltage discharge. When the high voltage pulsed electricity generated by the ignition coil is sent to the spark plug electrode, the high voltage. electricity will break down the mixture and generate an electric spark, this can ignite our car.
