IRON SALT DIESEL FUEL ADDITIVE COMPOSITION FOR IMPROVING PARTICULATE SUBSTANCE TRAP

摘要

PROBLEM TO BE SOLVED: To provide an additive composition which is stable and effective for improving the quality of a gas released by the combustion of a diesel fuel. SOLUTION: The fuel additive iron salt composition is effective for improving the action of a diesel engine particulate substance trap when it is added to a diesel fuel so as to give an iron content of 1-25 ppm to the fuel. The composition contains an oil-soluble or oli-dispersible neutral or perbasic iron salt of an acidic organic compound. In the composition, 50-99 mol% of all the iron is in a ferric state, the balance being in a ferrous state. COPYRIGHT: (C)2004,JPO
