Abstract:

The cetane number of aviation fuel remains a top concern to the U.S. Army as diesel engines are sensitive to cetane values of fuel. Some fuels originating from nonpetroleum sources contain low cetane numbers that have trouble operating in compression ignition engines. Cetane improvers additives can be used to improve the ignition quality of low cetane fuel. The United States Army Tank Automotive Research Development and Engineering Center TARDEC evaluated two 2-ethylhexyl nitrate additives to determine the effects of the additive on petroleum and synthetic based aviation fuel to determine the amount of a cetane improvement achievable. The negative impact of cetane improvers on thermal stability negates their use during fuel refining, blending and allowance into distribution systems. Since thermal stability of the fuel is not a concern for compression ignition engines, there is a potential benefit for the Army ground equipment.
