Where is the car spark plug installed?

[VanAddyson]

Car spark plugs are installed in the cylinders of the car. The gasoline engine ignition system introduces high-voltage current into the cylinder to generate an electric spark to ignite the combustible mixed gas. The standard of spark plugs usually uses the heat value to represent the thermal characteristics of the spark plug. The heat value of the spark plug indicates the balance ability of the spark plug insulator skirt to absorb and dissipate heat. The higher the heat value, the stronger the balance ability of heat absorption and dissipation. Therefore, hot-type spark plugs have a low heat value, while cold-type spark plugs have a high heat value. Steps to install car spark plugs: 1. Open the engine cover and pull off the cylinder wire by hand; 2. Use a special spark plug socket to remove the spark plug; 3. After taking out the original spark plug, put the new spark plug into the special spark plug socket; 4. Put the spark plug socket into the engine cylinder; 5. Connect the high-voltage split wire, install the spark plugs one by one, and then tighten the engine cover.
