Where does a spark plug go in an engine?
A spark plug is an electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed aerosol gasoline by means of an electric spark.
How does a spark plug change the current?
As the electrons flow from the coil, a voltage difference develops between the center electrode and side electrode. No current can flow because the fuel and air in the gap is an insulator, but as the voltage rises further, it begins to change the structure of the gases between the electrodes.
How are spark plugs used to prevent pre ignition?
Spark plugs cannot create heat, they can only remove heat. The temperature of the end of the plug\’s firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling.

How long do spark plugs last in a car?
The result is a rough running engine, skipping cylinders and other problems that cost you in performance and fuel economy. In terms of lifespan, the use life you enjoy will depend in the type of plug used in the engine. Normal copper plugs only last about 20,000 miles. However, using platinum plugs can give you 60,000 miles of use.
What does a spark plug do in a car?
It needs a way to ignite the fuel after mixing it with air from the intake. That’s what your car’s spark plugs do. They create an electrical spark (as the name implies) that ignites the fuel/air mixture and runs your engine. Spark plugs have advanced quite a bit from what they were a few decades back.
What happens when a spark plug is too short?
As the spark plug fires, minute amounts of the electrode evaporate. Eventually, it’s too short to create the spark needed to ignite the fuel/air mix. The result is a rough running engine, skipping cylinders and other problems that cost you in performance and fuel economy.
