with high hardness, clinging to the valve, piston head, cylinder wall, spark plug…Because carbon particles have a high hardness that causes cylinder scratches, along with an increasingly thick layer of soot, which changes the compression ratio of the engine, etc. This is the...
This avoids a great local increase in electrical field strength on the auxiliary ground electrode to minimize excessive discharge within the auxiliary spark gap to enhance carbon fouling resistance and durability of the spark plug.Koyama, Taiji

On mopeds, carbon fouling is caused by, most frequently first, stale old gasoline, fresh gasoline containing dissolved tar from a tarry gas tank, low compression, continuous low speed operation, spark plug heat range too cold, or a rich air-fuel mixture. ...
The spark plug is fitted into the cylinder head of an internal combustion engine and it plays a very important role while the combustion of the mixing fuel will happen inside the combustion chamber.Answer and Explanation: The common types of spark plug fouling ...
Heat range refers to the operating temperature range of the spark plug. A spark plug must run hot enough to burn off fouling deposits but not so hot that it causes preignition or detonation. Most spark plugs use a copper core and electrode design that gives them a broad heat range and ma...
Wet spark plug A wet spark plug means the plug has not been firing. If not due to engine flooding, the problem may be a bad ignition cable (excessive resistance, shorted or arcing). But wet fouling can also be caused by dirt or moisture on the outside of the plug that provides a co...
Spark Plug Fouling Resistance One thing all types of spark plugs must do is resist fouling. The trick here is to keep the electrodes hot enough to burn off fouling deposits but not so hot that they cause preignition. To burn off carbon deposits, the center electrode needs to reach about ...
Furthermore, the fouling of spark plugs is nothing but accumulating different deposits such as carbon on the electrodes. When it is functioning properly in normal conditions, the electrode of the plug attracts some particles from the ignition gas. They obviously block the gap between the two elect...
When the plug runs too cool soot and carbon iay deposit on the insulators causing fouling and missing. As an example, a truck or bus, when changed from city to highway traffic, may experience the difficulties described above as due to the plugs running too hot. In order to meet these ...
