Spark Plug is a vital part of a petrol engine’s ignition system. It delivers an electric spark inside the combustion chamber to ignite the air-fuel mixture, which powers the engine.
Key Functions
Ignites air-fuel mixture: Produces a high-voltage spark at the right time.
Transfers heat: Helps dissipate heat from the combustion chamber to the cylinder head.
Seals the combustion chamber: Prevents pressure leakage during combustion.
Typical Features
