Cetane number: 1. The auto-ignition quality of diesel fuel. 2. A rating applied to diesel fuel similar to octane rating for gasoline. 3. A measure of how readily diesel fuel starts to burn (auto ignites) at high compression temperature. Diesel fuel with a high cetane number auto-ignites shortly after injection into the combustion chamber. Therefore, it has a short ignition delay time. Diesel fuel with a low cetane number resists auto-ignition. Therefore, it has a longer ignition delay time.
