The fuel with the lowest ignition temperature is:
- LPG (Liquefied Petroleum Gas)
- Kerosene
- Diesel
- Petrol
LPG ignites at a lower temperature compared to the others, making it more flammable.

Kerosene, Diesel, Petrol, and LPG: Ignition Temperature Comparison
Introduction:
Ignition temperature refers to the minimum temperature at which a substance can ignite or catch fire spontaneously without an external ignition source. Different fuels have different ignition temperatures, which determine their safety and suitability for various applications. In this context, we will compare the ignition temperatures of kerosene, diesel, petrol, and LPG (liquefied petroleum gas) to determine which fuel has the lowest ignition temperature.
Ignition Temperature Comparison:
The ignition temperatures of various fuels are influenced by their chemical composition, volatility, and other factors. Let's compare the ignition temperatures of kerosene, diesel, petrol, and LPG:
1. Kerosene:
- Ignition Temperature: Kerosene has an ignition temperature of approximately 220-260°C (428-500°F).
- Explanation: Kerosene is a flammable liquid hydrocarbon fuel commonly used in lamps, heaters, and jet engines. It has a relatively low ignition temperature, making it easy to ignite with a spark or flame.
2. Diesel:
- Ignition Temperature: Diesel has an ignition temperature of around 210-300°C (410-572°F).
- Explanation: Diesel is a heavier and less volatile fuel compared to kerosene. It requires a higher temperature to reach its ignition point. Diesel engines use compression ignition, where the fuel ignites due to the heat generated by the compression of air in the engine cylinder.
3. Petrol:
- Ignition Temperature: Petrol, also known as gasoline, has an ignition temperature of approximately 246-280°C (475-536°F).
- Explanation: Petrol is a highly flammable liquid fuel commonly used in spark-ignition engines. It has a lower flash point and ignition temperature compared to diesel, making it easier to ignite with a spark.
4. LPG (Liquefied Petroleum Gas):
- Ignition Temperature: LPG, consisting of propane and butane, has an ignition temperature of about 410-580°C (770-1076°F).
- Explanation: LPG is a highly volatile and flammable gas commonly used as a fuel for cooking, heating, and vehicles. It requires a higher temperature to ignite compared to liquid fuels like kerosene, diesel, and petrol.
Conclusion:
Among the given options, LPG (liquefied petroleum gas) has the highest ignition temperature, making it the safest fuel in terms of ignition hazards. Kerosene, diesel, and petrol have lower ignition temperatures compared to LPG. It is essential to handle and store these fuels properly to prevent accidental ignition and subsequent fires.
