This is not the same temperature as the flash point (as read elsewhere on this web site). Flash point of gasoline is negative 45 degrees Fahrenheit, where vapors form fast enough to not be diluted by the air so that the fuel to air ratio is high enough that an alternate source of very high heat (like a spark) can ignite the vapors momentarily, thus removing the vapors from the considered area, and the fire extinguishes. Thus, a flash is seen, hence the term flash point.
The fire point is the temperatue where vapors form fast enough to sustain a combustible fuel/air mixture.
Ignition point is the temperature of the aforementioned alternate source of high heat, such as a spark, that ignites the a mixture of air and fuel or oxidizer and fuel. I've read elsewhere the ignition point of gasoline and oxygen is 280 degrees Celcius (536 degrees Fahrenheit), and I came here looking for confirmation.

What is auto ignition temperature for Lpg?
410-580 degree c
What is the auto-ignition temperature of kerosene?
The auto-ignition temperature of kerosene is typically in the range of 210-300 degrees Celsius (410-572 degrees Fahrenheit), depending on the specific composition and purity of the kerosene.
What temperature can you heat gasoline to before it ignites?
Gasoline does not ignite. The fumes from gasoline are what ignites. They will ignite at any temperature. According to the best sources I could find there are three answers (all apply to gas fumes as stated above). 1.) Flash point -43 F 2.) Ignition Temp -40 both of the above require an external source of ignition. Then ..... 3.) Auto Ignition Temp 246--280 °C (475--536 °F) Is the answer for what temp it will ignite on it's own without external 'spark'. I leaned heavily on Wikipedia for source material
Why is gasoline coming out of the ignition switch?
Why is gasoline coming out of the ignition switch?
What is the definition of auto-ignite?
Auto-ignite refers to the spontaneous ignition of a substance without an external ignition source, typically due to high temperature or pressure. It occurs when the substance reaches its auto-ignition temperature or pressure and ignites without the need for a spark or flame.
What is the auto-ignition temperature of the flammable mixture?
The auto-ignition temperature of a flammable mixture is the lowest temperature at which it will spontaneously ignite without an external ignition source, such as a flame or spark. It varies depending on the specific components of the mixture, but it is typically in the range of 300-500 degrees Celsius for most flammable gases and vapors.
Why did Nikola Tesla invented the auto ignition?
Gasoline cars were turned on by a manual system. It was a technology of a rotating aparatus that had a lever that used the hands and arms of the operator in order to turn on the car. Tesla came out with the solution. The Tesla auto ignition patent 649621.
What is autoignition temperature?

Is nitrogen gas at high temperature and pressure flammable is there is no temperature and pressure at which nitrogen gas can be flammable?
Nitrogen gas is not in itself flammable, and does not have an auto ignition temperature.
How do you measure flashpoint of gasoline?
The flashpoint of gasoline can be measured using a closed-cup tester designed to determine the lowest temperature at which the gasoline vapor can ignite when exposed to an ignition source under specific conditions. This is an important safety parameter to assess the flammability risk of a substance.
What is spark ignition engine?
A 'spark ignition ' engine is your regular gasoline engine as opposed to a diesel, which is a 'compression ignition' engine
What is auto ignition and why is it haunting me?
Auto ignition is basically oxidation of a substance without an ignition source. The energy of activation is reached to result in a liberation of heat (exothermic). That then leads to a chain of events leading to a fire hazard. It's easy to get auto ignition mixed up with flashpoint (flashpoint requires a source of ignition such as temperature input or flame source). In all, I haven't found any sources that describe the whole mechanism. Some say the formation of hyperoxidases from drying oils is one of the culprits.
