Introduction to Spark Plug
A spark plug is a crucial component in an internal - combustion engine. It is responsible for igniting the air - fuel mixture within the engine's combustion chamber. When an electrical current is sent to the spark plug, it creates a spark across a small gap at the end of the plug. This spark ignites the compressed air - fuel mixture, which then releases energy to power the engine. The performance of a spark plug can significantly affect an engine's power, fuel efficiency, and emissions. A high - quality spark plug can ensure smooth engine operation, reduce misfires, and improve overall vehicle performance.
