How are spark plug grades classified?
1 Answers
Currently, spark plugs come in various material grades, each with different performance characteristics and replacement intervals. They can be broadly categorized into: nickel alloy spark plugs, platinum spark plugs, and iridium spark plugs. From a manufacturing process perspective, there are thick electrode spark plugs, needle electrode spark plugs, double platinum spark plugs, iridium-platinum spark plugs, and double needle iridium spark plugs, among others. Additional information: 1. Function of spark plugs: The material of spark plugs usually refers to the electrode material. Currently, platinum and iridium spark plugs are considered the best. Platinum and iridium are precious metals with excellent resistance to high temperatures, high pressure, and corrosion. Using these materials for spark plugs can significantly extend their service life, but they are also more expensive. 2. Replacement intervals for spark plugs: Nickel alloy spark plugs should be replaced every 20,000 to 30,000 kilometers, nickel-yttrium alloy spark plugs every 30,000 kilometers, platinum spark plugs every 40,000 kilometers, double platinum spark plugs every 60,000 kilometers, iridium spark plugs every 80,000 kilometers, and platinum-iridium alloy spark plugs can last up to 100,000 kilometers before needing replacement.
