Internal Combustion Engines
Volatility of diesel fuel oil is

Temperature at which it solidifies or congeals

Minimum temperature to which oil is heated in order to give off inflammable vapours in sufficient quantity to ignite momentarily when brought in contact with a flame

It catches fire without external aid

Indicated by 90% distillation temperature, i.e., when 90% of sample oil has distilled off
