Spark plugs are essential engine components in gasoline-powered vehicles. They ignite the air-fuel mixture in the combustion chamber, creating a spark that initiates the combustion process.
This controlled explosion drives the engine’s pistons, producing power to propel the vehicle forward.
Glow plugs are heating devices used in diesel engines to aid cold starting. They preheat the combustion chamber to raise the air temperature, helping to ignite the fuel when the engine is cold.
This ensures smoother and more reliable starts in colder conditions.
