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]
Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. [1]
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 ...
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 ...
Both CII and CCAI are calculated from the density and kinematic viscosity of the fuel. CII was developed by BP to calculate the autoignition capacity of heavy fuel oils (HFO). It is calculated using the measured kinematic viscosity V (cSt or mm 2 /s) of a given fuel determined at temperature t (°C) and the density ρ 15 at 15°C (kg/m 3). [1]
It was the primary U.S. Air Force jet fuel between 1951 and 1995. ... (−60 °C), and its maximum burning temperature was 6,670 °F (3,688 °C). [citation needed]
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).
Jet fuel is a gas turbine fuel used in propeller and jet fixed-wing aircraft and helicopters. It has a low viscosity at low temperature, has limited ranges of density and calorific value , burns cleanly, and remains chemically stable when heated to high temperature.
