Webb17 nov. 2024 · In comparison, spontaneous combustion, also called auto-ignition, detonation, or knock, happens when rising temperature and pressure from the primary combustion causes unburned fuel to ignite. This uncontrolled secondary combustion causes pressure in the cylinder to spike and causes the knock to occur. Webb27 apr. 2024 · The heating process during combustion could be divided into four stages: a latent period of spontaneous combustion, a slow spontaneous heating period, an accelerated spontaneous heating period, and a period of combustion.

WebbSpontaneous combustion is a condition - temperature and pressure - at which a material, in this case, diesel - combusts without a spark. The diesel engine’s efficiency can be attributed to its higher compression ratio; i.e. the ratio of the highest volume to the lowest volume in the compression chamber in a diesel engine is much higher.

Webb7 juli 2024 · Spontaneous combustion of oily rags occurs when rag or cloth is slowly heated to its ignition point through oxidation. A substance will begin to release heat as it oxidizes. If this heat has no way to escape, like in a pile, the temperature will rise to a level high enough to ignite the oil and ignite the rag or cloth. Webb24 feb. 2024 · Finally, “spontaneous combustion” usually means a process where some slow oxidization reaction (i.e. in a hay bale or compost pile) generates heat which builds up, raising the temperature, which speeds the reaction, more heat, higher temp, faster reaction, until finally the auto ignition temp is reached and combustion starts.

Mary Reeser (1884–1951) of St. Petersburg, Florida was most likely a victim of the wick effect. It was suspected that she had accidentally ignited herself with a cigarette. The fat which over time had been absorbed by her clothing likely acted as fuel for the fire. At the scene, investigators found melted fat in the rug near Mary's body. An investigation of a 1963 case in Leeds included an experiment with a wick effect.
