Fuels with lower cetane number have longer ignition delays, requiring more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher cetane number fuels. In Europe, diesel cetane numbers were set at a minimum of 38 in 1994 and 40 in 2000.

A cetane number is a measure of the delay of ignition of a diesel fuel. [32] A higher cetane number indicates that the fuel ignites more readily when sprayed into hot compressed air. [32] European (EN 590 standard) road diesel has a minimum cetane number of 51. Fuels with higher cetane numbers, normally "premium" diesel fuels with additional ...
In Europe this is governed by the EN 590 standard which had ... Properties beyond Class 4 would require a kerosene type fuel with a low cetane number (at least 45 in ...
Ordinary European petrol is typically 95 RON, 85 MON, equal to 90 AKI. As a compression ignition engine fuel, both alcohols create very few particulates, but their low cetane number means that an ignition improver like glycol must be mixed into the fuel at approx. 5%.
The cetane number is a key property of diesel fuel, as it measures its aptitude to self-ignite in the combustion chamber. [8] The auto ignition temperature of diesel fuel is around 220 °C (428 °F) at atmospheric pressure. Cetane improver additives are used to decrease this temperature and lead to quicker combustion, by increasing the cetane ...
Cetane index is used as a substitute for the cetane number of diesel fuel. The cetane index is calculated based on the fuel's density and distillation range (ASTM D86). There are two methods used, ASTM D976 and D4737. The older D976, or "two-variable equation" is outdated and should no longer be used for cetane number estimation.
Nitromethane can increase the cetane number of diesel fuel, improving its combustion properties; Nitrous oxide, or simply nitrous, is an oxidizer used in many forms of motorsports such as drag racing and street racing.
