Where is the location of a car engine's spark plug?

The spark plug of a car engine is located at the top of the engine. The spark plug uses high-voltage discharge to break down the air between the electrodes, generating an electric spark to ignite the combustible gas mixture in the combustion chamber, thereby maintaining the engine's operation. The quality of the spark plug directly affects the performance of the car engine. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, and pole-type spark plugs. Spark plugs require regular maintenance. When the car's engine speed is 1,000 RPM, the spark plug needs to perform 500 times per minute, making it one of the busiest components in a car. During maintenance, use gasoline or kerosene to soften the carbon deposits first, then clean them with a non-metallic brush, and finally dry them with compressed air. Avoid using a knife to scrape off deposits, as this can damage the electrodes.
I think the location of spark plugs is quite easy to find on a car engine. They are usually installed on the cylinder head of the engine, one for each cylinder, protruding like little mushroom heads. After opening the hood, you'll see a row of ignition coils or wiring harnesses connected to these spark plugs. The position varies depending on the engine type - for example, spark plugs on inline engines are clearly visible at the top, while those on V-type engines might be hidden in grooves on both sides. When checking them yourself, first turn off the engine and let it cool down to avoid burns. Their location is crucial because they're responsible for ignition - if carbon builds up, it can affect starting or fuel consumption. Regular cleaning can make your car more durable and save on repair costs.
