Spark Plug

The spark plug is a crucial component in internal combustion engines (primarily gasoline/petrol engines).   Its main functions are:

Igniting the Air-Fuel Mixture – It generates an electric spark to ignite the compressed air-fuel mixture in the combustion chamber, initiating the power stroke.

Heat Dissipation – It helps transfer excess heat from the combustion chamber to the engine’s cooling system.

Sealing the Combustion Chamber – It ensures proper compression by sealing the combustion chamber against high-pressure gases.

In summary, the spark plug ensures efficient combustion, engine performance, and fuel economy.
