Spark Plug

Listing ID #3395961

Spark Plug has a role to ignite and make an explosion inside engine. This explosion makes a piston move up and down. This movement will communicate power to a drive chain or a V belt. This small part has a big role to work engine. The spark plug's secondary function is to remove heat from the combustion chamber (the primary function is discussed above). The figure below shows a general structure of sparkplug. The actual heat distribution will vary depending on the operating conditions and cylinder head and spark plug design.
