Which Is Easier to Ignite, Diesel or Gasoline

Gasoline is more susceptible to ignition than diesel. Despite gasoline’s ignition point being above 400 degrees Celsius and diesel’s over 200 degrees Celsius, gasoline ignites far more easily.

Gasoline’s significantly lower boiling point means it quickly evaporates into the air, creating a flammable vapor, making it more volatile than diesel, which vaporizes less readily.
