What is the working principle of a spark plug?
1 Answers
The working principle of a spark plug is that the electrode of the spark plug generates a pulsed high voltage through repeated and continuous ignition, which breaks down the air between the two electrodes of the spark plug, creating a spark and causing an explosion to ignite the mixed gas in the cylinder. Subsequently, the engine starts to operate. Spark plugs are consumable items and need to be replaced regularly. Choosing spark plugs with different heat values can easily affect the engine's output, and it is even possible for the spark plug to be directly damaged. The heat value of a spark plug is represented by numbers, and different brands have different heat values. Each brand's heat value corresponds to specific vehicle models.
