WebDefinition. In the context of a combustible fuel mixture, the auto-ignition temperature is the lowest temperature at which the fuel will spontaneously ignite in a normal atmosphere without an external source of ignition such as a flame or spark. This temperature is sometimes referred to as the kindling point of the fuel. WebFor 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 …

WebA spark plug’s heat range is the degree to which it disperses heat. Spark plugs with high heat dispersal are referred to as cold, while plugs 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. eerily perfectWebThe autoignition temperature of a substance is the minimum temperature required to initiate or cause self-sustained combustion, in the absence of a spark or flame.
