What is a Spark plug?

A spark plug is a vital component in internal combustion engines, essential for initiating the engine's combustion process. It generates a high-voltage electric spark to ignite the air-fuel mixture. Spark plugs are primarily used in gasoline engines and are not required in diesel engines.

The structure of a spark plug includes:
✅Metal shell
The outer casing that allows the plug to be mounted in the engine.
✅Ceramic insulator
A material that prevents high voltage from leaking.
✅Central and ground electrodes
The components responsible for generating the spark. When high voltage flows through the central electrode, it creates a spark with the ground electrode.

The roles of a spark plug are as follows:
✅Ignition
Efficiently ignites the air-fuel mixture in the engine's combustion chamber.
✅Enhancing engine performance
Optimizes the combustion process to improve output.
✅Improving fuel efficiency
Ensures precise ignition timing to minimize fuel wastage.

If a spark plug becomes worn or dirty, it can lead to poor engine starts, reduced fuel efficiency, and overall diminished performance. Regular inspection and replacement are essential for maintaining engine efficiency.
