Under high voltage, the air between the center electrode and the side electrode of the spark plug will rapidly undergo ionization, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain value, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulation, and the gap forms a discharge channel, resulting in "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark".

Spark plug, commonly known as flame nozzle, is used to discharge the pulse high-voltage electricity sent by the high-voltage wire (flame nozzle wire), breakdown the air between the two electrodes of the spark plug, and generate an electric spark to ignite the mixed gas in the cylinder. The main types include: standard type spark plugs, edge protruding spark plugs, electrode type spark plugs, seat type spark plugs, pole type spark plugs, surface jumping spark plugs, etc.
