Where is the car's spark plug located?

[ColtonLee]

Where is the spark plug located: The spark plug is installed on the side or top of the engine. In early designs, spark plugs were connected to the distributor via ignition cables. Over the past decade, most small car engines have transitioned to direct connection between the ignition coil and the spark plug. What is a spark plug: The spark plug is a critical component of a gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber, causing it to jump the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. What are the components of a spark plug: A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and metal shell. What types of spark plugs are there: The main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat-type spark plugs, surface gap spark plugs, and surface discharge spark plugs.
