Many novice car owners don't know much about the role of auto parts, such as the use of spark plugs. Let's take a look at the function and replacement time of automobile spark plugs.

The function of automobile spark plug is to ignite. The electrode of the spark plug generates high voltage volts, forming an electric spark, igniting the mixed gas in the engine cylinder, exploding and burning, thus pushing the piston to move, and then the engine runs before the car can run.

There are many kinds of spark plugs. The replacement cycle of spark plugs with different materials is different. If it is an ordinary nickel alloy spark plug, the vehicle needs to be replaced once after driving 20 thousand kilometers. If it is a platinum alloy spark plug, the vehicle needs to be replaced once it travels 40 thousand kilometers; If it is an iridium alloy spark plug, the service life is relatively long, and the general vehicle needs to be replaced after driving 60,000 ~ 80,000 kilometers.
