Cetane - (AMAL-CIA-2009) Cetane (AMAL-CIA-2009) Amalgamated, Inc uses 2EHN (2-ethyl-hexyl-nitrate) for its cetane ignition improver. Industry data was collected several years ago for 2EHN and an industry accepted response curve was developed. This industry Cetane Response Curve is used to determine how much 2EHN is needed to improve the engine cetane number. The reaction of diesel fuel to cetane improver additive is directly dependent on the responsiveness of the fuel. “Higher response” fuels show greater improvement in cetane numbers with the addition of 2EHN than the equivalent percentage of 2EHN in “average responding” and “lower responding” fuels. Cetane Engine requirements vary worldwide. See Cetane Improver - An Introduction item. Amalgamated has Cetane available in bulk, tote, drum, and small packaging.
