What are the types of NGK spark plugs?
1 Answers
Here are the types of NGK spark plugs: 1. Iridium Alloy Spark Plug: The center electrode is made of iridium alloy, and the outer electrode discharge area also uses platinum alloy, making it a high-performance, long-life spark plug that can suppress electrode wear. 2. High Ignition Iridium Alloy Spark Plug (SPE Type): By adopting a fine-diameter center electrode and a bevel-cut design at the front of the outer electrode, it can concentrate the spark at the front while suppressing quenching effects. Additionally, square platinum alloy particles are welded onto the outer electrode to ensure durability. 5. High Ignition Iridium Alloy Spark Plug (PSPE Type): By shortening the outer electrode, it reduces the coverage effect on the center electrode and minimizes quenching effects, further enhancing ignition performance. It also suppresses overheating of the outer electrode, providing excellent resistance to breakage, making it a high-performance, long-life spark plug capable of stable combustion even in high-compression ratio engines.
