What does the term 'electrode gap' refer to in spark plug maintenance?

The term 'electrode gap' specifically refers to the space between the two electrodes of a spark plug. This gap is critical for optimal ignition because it influences the voltage needed to create a spark. When the gap is set correctly, the spark plug can ignite the air-fuel mixture in the engine efficiently, leading to better performance and efficiency of the engine. If the gap is too wide or too narrow, it can result in misfires, reduced fuel efficiency, and engine performance issues. Proper maintenance of this gap is essential for ensuring that the spark plug functions as intended, which directly impacts the operation of engines, including those in chainsaws.
