The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. [1]
However, the presence of energetic free radicals during decomposition, particularly in hot gases or mists, can cause auto-ignition to occur at a lower temperature than would otherwise be normal for a similar chemical structure without the peroxy functional group.

The high compression ratio in the auxiliary combustion chamber causes the auto-ignition of the homogeneous lean air-fuel mixture therein (no spark plug required); the burnt gas bursts - through some "transfer ports", just before the TDC - into the main combustion chamber triggering its auto-ignition. The engine needs not be structurally stronger.
Assume company Zander has the following numbers: Average total Assets = ($40,000 + $80,000) ÷ 2 = $60,000. Asset turnover ratio = $125,00 ÷ $60,000 = 2
In 2023, Coca-Cola generated $45.754 billion in revenue and reported $10.905 billion in fixed assets. This gives the company a fixed asset turnover ratio of 4.2x for the year. This shows that Coca ...
A lean flashover (sometimes called rollover) is the ignition of the gas layer under the ceiling, leading to total involvement of the compartment. The air–fuel ratio is at the bottom region of the flammability range (i.e. lean). A rich flashover occurs when the flammable gases are ignited while at the upper region of the flammability range (i ...
Rep. Nancy Mace, R-S.C., says she was 'physically accosted' on the Capitol grounds over her fight to protect women. Police have charged an Illinois man with assaulting a government official.
