Where is the engine spark plug located?

[SanAaron]

The engine spark plug is located inside the engine cylinder, which can be clearly seen after removing the high-voltage ignition coil. The spark plug, commonly known as the sparking plug, functions to discharge the pulsed high-voltage electricity delivered by the high-voltage wire (spark plug wire), breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the mixed gas in the cylinder. The engine is suitable for both power generation devices and can also refer to the entire machine including the power device (such as gasoline engines, aircraft engines). Its types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), gas turbines (racing cars), electric motors, etc.
