The most common original car spark plugs are nickel alloy spark plugs. These spark plugs are typically used for around 20,000 kilometers and have average performance.
Spark plug life is related to the electrode material, spark plug brand and other factors. Generally, ordinary nickel alloy spark plugs need to be replaced once every 20,000 kilometers, which has the shortest service life. ; platinum alloy spark plugs need to be replaced every 40,000 kilometers; iridium spark plugs can be replaced between 60,000 and 80,000 kilometers and have a long lifespan. But these are just some reference values, and they will depend on the use of the spark plug.
Classification of spark plug material grades
There are roughly alnickel alloy lumage, platinum spark plugs, platinum iridium spark plugs and gold iridium spark plugs. Among these materials, the platinum iridium spark. Spark plugs and iridium gold spark plugs are both good.
In addition to choosing the material of the spark plug, car owners also need to pay attention to the choice of the calorific value of the spark plug. It is best to choose a calorific value that matches that of the original car. Too big or too small. the calorific value will have a certain impact.
If the calorific value is reduced, insufficient combustion of the oil-gas mixture may occur, resulting in insufficient power. Insufficient heat dissipation may even cause the spark plug to become too hot, further causing deflagration and others. phenomena. If the calorific value ofthe spark plug increases, the heat dissipation capacity will be stronger, the temperature of the spark plug will drop faster, and carbon deposits will easily form on the ignition head, causing power failure and preventing the spark plug to light. .
