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]
The differences between Jet A and Jet A-1 are twofold. The primary difference is the lower freezing point of Jet A-1 fuel: [7] Jet A's is −40 °C (−40 °F) Jet A-1's is −47 °C (−53 °F) The other difference is the mandatory addition of an antistatic additive to Jet A-1 fuel.
A diesel-fueled engine has no ignition source (such as the spark plugs in a gasoline engine), so diesel fuel can have a high flash point, but must have a low autoignition temperature. Jet fuel flash points also vary with the composition of the fuel. Both Jet A and Jet A-1 have flash points between 38 and 66 °C (100 and 151 °F), close to that ...
It had a lower flash point than JP-1, but was preferred because of its greater availability. It was the primary U.S. Air Force jet fuel between 1951 and 1995. MC-77 is the Swedish military equivalent of JP-4. [3]
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.
Fuel oil no. 1, known by various names including kerosene, range oil, coal oil, or Jet-A (aviation) fuel, encompasses a carbon range of C9 to C17. Its flash point ranges between 110 degrees F and 162 degrees F (42 degrees C - 72 degrees C), while its ignition temperature is recorded at 410 degrees F (210 degrees C).
Kraft's résumé is a bit different. The 83-year-old purchased a controlling stake in the Patriots in 1994 and has since presided over the most successful franchise of the 21st century.
The fire point, or combustion point, of a fuel is the lowest temperature at which the liquid fuel will continue to burn for at least five seconds after ignition by an open flame of standard dimension. [1] At the flash point, a lower temperature, a substance will ignite briefly, but vapour might not be produced at a rate to sustain the fire ...
