Internal Combustion Engines
Volatility of diesel fuel oil is

Temperature at which it solidifies or congeals

It catches fire without external aid

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

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
