What happens if you use a spark plug that doesn't heat up?
If you use too cool of a spark plug that doesn’t heat up to the proper temperature, it won’t be able to burn off the carbon deposits, which can cause premature fouling. A fouled spark plug can lead to misfires and engine stalling.
Why are cold spark plugs good?
Cold spark plugs are good for high RPM engines and other situations where the engine operates at a high temperature. Because they transfer heat faster, cold spark plugs can get dirty and become fouled sooner because they don’t get hot enough to burn off carbon deposits.
What is the purpose of spark plugs?
While the primary function of the spark plugs is providing the spark to ignite the air/fuel combination and start the engine, an equally important function of the engine’s spark plugs is to remove heat away from the combustion chamber.
Why do spark plugs need to be hot?
Found in many passenger vehicles, hot spark plugs have more insulation to transfer the heat slowly, which keeps the temperature high enough to burn off carbon deposits and avoid premature fouling. This helps allow for more time between spark plug changes.
What is a spark plug?
Spark plugs act as a heat exchanger, pulling thermal energy away from the combustion chamber and transferring it to the engine’s cooling system.
What is the difference between a hot and cold spark plug?
Spark plugs with high heat dispersal are referred to as cold, while plug s with less heat-dissipating characteristics are known as hot. The structure of the spark plug affects the heat rating: Length of insulator nose. Surface area. Material of center electrode. Position of the insulator tip.
What happens if you pick a spark plug too hot?
Picking a spark plug with too hot of a heat range can result in overheating, causing electrodes to wear quickly, leading to pre-ignition and a reduction in fuel economy. No matter what type of spark plug you are looking for, Champion ® has a spark plug for your engine.
