Abstract
A fuel composition, preferably for use in internal combustion engines, comprising a water-in-oil emulsion of (a) a hydrocarbon fuel, such as gasoline, diesel fuel or fuel oil; (b) water; (c) preferably a water-soluble alcohol; and (d) a novel combination of surface-active agents to provide a clear composition which is stable against phase separation over a wide range of temperatures.
Claims16
A clear, liquid fuel composition which comprises:
- (a) a hydrocarbon fuel;
- (b) about 0.1% to about 10% by weight water;
- and
- (c) a surface-active amount of a combination of surface-active agents consisting of:
- (i) a saturated or unsaturated long-chain fatty acid salt having from 12-18 carbon atoms or a mixture thereof;
- (ii) a free unsaturated long-chain fatty acid having from 12-18 carbon atoms, or a mixture of free unsaturated and saturated long chain fatty-acids having from 12-18 carbon atoms;
- and
- (iii) a non-ionic surfactant.
