Abstract
Platinum group metal fuel additives are effective in fuel environments which make the exclusion of water impractical. The fuels additives comprise a platinum group metal compound and a water-functional composition selected from the group consisting of lipophilic emulsifiers, lipophilic organic compounds in which water is miscible and mixtures of these. The additives are preferably effective in fuel compositions having water contents of at least about 0.01% water by weight.
Claims20
A fuel additive composition for providing a catalyst to the fuel and minimizing the degradation of catalytic activity by preventing the frank separation of water from the fuel and, thereby maintain the catalyst in the fuel, comprising:
- a platinum group metal compound and
- a water-functional composition selected from the group consisting of lipophilic emulsifiers, lipophilic organic compounds in which water is miscible, and mixtures of these;
- wherein said platinum group metal compound is present in an amount to provide from 0.05 to 2.0 milligrams of platinum per liter of fuel.
A fuel composition comprising:
- a distillate fuel;
- and,
- a fuel additive comprising a platinum group metal compound present in an amount sufficient to provide from about 0.1 to about 1.0 milligram of platinum group metal for each liter of fuel and a water-functional composition selected from the group consisting of lipophilic emulsifiers, lipophilic organic compounds in which water is miscible, and mixtures of these.
A method for operating an internal combustion engine comprising:
- adding to the fuel system of an internal combustion engine, a fuel composition comprising a distillate fuel and, a fuel additive comprising a platinum group metal compound the platinum group metal compound is present in an amount sufficient to provide from about 0.1 to about 1.0 milligram of platinum group metal for each liter of fuel, and a water-functional composition selected from the group consisting of lipophilic emulsifiers, lipophilic organic compounds in which water is miscible and mixtures of these, said fuel composition within said fuel system having a water content of at least about 0.01% water by weight;
- and
- combusting the fuel composition within the engine.
