What is the function of the spark plug?

The function of the spark plug is to introduce tens of thousands of volts of high-voltage electricity into the combustion chamber and generate electric sparks to ignite the mixture. Working with the ignition system and the fuel supply system to make the engine work, it largely determines the performance of the engine. Spark plugs are the daily consumables of automobiles. As the core of automobile engines, the performance of a spark plug can almost directly determine the performance of a car, so you should always check the spark plug of your car.
