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.
Claims55
A diesel fuel additive, comprising:
- one or more hydrocarbon solvents predominantly including carbon numbers between C6 and C16 at less than 65% concentration by weight;
- a cetane number improver, soluble in the one or more hydrocarbon solvents, at 20% to 85% concentration by weight;
- 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.
