Do spark plugs work continuously?

[LaEverett]

Spark plugs do not work continuously; they only operate when the engine is running. The working principle of an engine involves the four strokes of the cylinder: intake stroke, compression stroke, ignition stroke, and exhaust stroke. These four strokes are in a continuous cycle, with the ignition stroke being the process where the spark plug fires. Spark plugs, commonly known as sparkers, function by discharging the high-voltage pulses sent through the high-tension leads, breaking down the air between the two electrodes to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface-gap spark plugs.
