Prefix

• The spark plug in a motorcycle is a crucial component of the ignition system that ignites the air-fuel mixture in the engine’s combustion chamber. It consists of a metal shell, an insulator, and a central electrode. When the engine’s ignition system sends a high-voltage electrical current through the spark plug, it generates a spark at the gap between the central electrode and the ground electrode. This spark ignites the air-fuel mixture, causing combustion and powering the engine. The spark plug is essential for smooth engine operation, fuel efficiency, and overall performance.
