Abstract
A diesel fuel additive includes a cetane number improver and an at least one organometallic combustion catalyst in solution and/or at least one metal-oxide combustion catalyst in suspension.
Claims18
A diesel fuel additive, comprising:
- one or more hydrocarbon solvents, predominantly including carbon numbers between C6 and C16, the one or more hydrocarbon solvents being at less than 65% concentration by weight in the diesel fuel additive as a whole;
- a cetane number improver, soluble in the one or more hydrocarbon solvents, at 20% to 85% concentration by weight in the diesel fuel additive as a whole;
- and
- at least one organometallic combustion catalyst including a positive oxidation state metal ion in a coordination complex providing solubility in the one or more hydrocarbon solvents, the at least one organometallic combustion catalyst being at 0.1% to 30% total concentration by weight in the diesel fuel additive as a whole;
- wherein organic components of the diesel fuel additive consist essentially of molecules having carbon numbers of C19 or less.
