11 maj 2018 · This is a comparison of a cold heat range plug (left) versus a much hotter heat range plug (right). Notice how the distance between the ceramic and the spark plug shell on the hotter plug requires heat to travel a farther distance, which maintains more heat in the spark plug.
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.
an indication of heat range when reading the spark plugs. It Appears that the increased use of oxygenated fuels (up to 10%) does not directly affect the core nose temperature of the spark plug.
For a spark plug to function properly, it must have a tip temperature high enough to burn off carbon deposits (self-cleaning) and avoid fouling, while remaining low enough to avoid overheating the ceramic firing end and pre-ignition.
Learn what a spark plugs heat range means & use our cross reference table. Using a spark plug with the correct heat range is critical for engine compatibility.
1. Stay cool enough to avoid pre-ignition and/or electrode destruction. 2. Run hot enough to burn off combustion deposits that would otherwise collect at the firing tip. 3. Adapt to specific engine characteristics and widely varying driving/load conditions.
30 lip 2024 · The heat range of a spark plug refers to its ability to dissipate heat from the combustion chamber. This characteristic is critical because it affects how well the spark plug can perform under varying engine conditions.
