Where is the Spark Plug Located?

[LePatrick]

The spark plug is located inside the engine cylinder. It can be clearly seen after removing the high-voltage ignition coil. The spark plug utilizes high-voltage discharge to break down the air between electrodes, generating an electric spark to ignite the combustible gas mixture in the combustion chamber, thereby maintaining engine operation. The main types of spark plugs include: standard spark plugs, insulator-protruding spark plugs, electrode-type spark plugs, seat-type spark plugs, and pole-type spark plugs. Since every engine operation requires the spark plug to perform work, the quality of the spark plug directly affects the performance of the car's engine. An engine is a machine capable of converting other forms of energy into mechanical energy.
