    en.wikipedia.org/wiki/Cetane_improver

    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 ...
