Cetane number is a defined parameter designed to provide an indication of the ignition quality of diesel fuels. A higher cetane number means that the fuel has better ignition quality than fuels with lower cetane numbers. Cetane number is a measure of a fuel’s ignition delay, which is the time period between the start of injection and the start of combustion of the fuel in the engine. A fuel which has a shorter ignition delay will have a higher cetane number and vice versa.
