What is the Function and Purpose of Spark Plugs?

Spark plugs play a crucial role in the ignition system of an internal combustion engine. The ground electrode of a spark plug is connected to the metal shell, which is in turn threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that comes into contact with the high-voltage coil. When current passes through the terminal nut and the central electrode, it ionizes the medium between the central electrode and the ground electrode, creating a spark that ignites the air-fuel mixture in the combustion chamber. Spark Plug Replacement Intervals: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this can vary depending on the brand and engine type, so it's advisable to follow the manufacturer's manual. Here are some general guidelines for replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs between 60,000 to 80,000 kilometers.
