Where is the spark plug located in a car?

The spark plug is located on the car's engine. Generally, after opening the hood, there will be a cover on the engine. Removing this cover will reveal several wire harnesses directly connected to the engine. The spark plugs are found beneath these wire harnesses. The spark plug functions by using high-voltage discharge to ionize the air between electrodes, generating an electric spark to ignite the combustible air-fuel mixture in the combustion chamber, thereby sustaining engine operation. The main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, and pole spark plugs. Spark plugs require regular maintenance. For instance, if the car's engine speed is 1,000 RPM, the spark plug needs to fire 500 times per minute. During maintenance, it is essential to first soften carbon deposits using liquids such as gasoline or kerosene, then clean them with a non-metallic brush, and finally dry them with compressed air. It is crucial to avoid using methods like scraping with a knife, as this could damage the electrodes.
