Emulsified water-blended fuel compositions
First Claim
1. An emulsified water-blended fuel composition comprising:
- (A) about 50 to about 99% by weight of a hydrocarbon boiling in the gasoline or diesel range;
(B) about 1 to about 50% by weight of water (C) a minor emulsifying amount of at least one fuel-soluble salt comprised of (I) a first polycarboxylic acylating agent, said first polycarboxylic acylating agent having at least one hydrocarbyl substituent of about 20 to about 500 carbon atoms, (II) a second polycarboxylic acylating agent, said second polycarboxylic acylating agent optionally having at least one hydrocarbyl substituent of up to about 500 carbon atoms, said polycarboxylic acylating agents (I) and (II) being coupled together by (III) a linking group derived from a linking compound having two or more primary amino groups, two or more secondary amino groups, at least one primary amino group and at least one secondary amino group, at least two hydroxyl groups, or at least one primary or secondary amino group and at least one hydroxyl group, said polycarboxylic acylating agents (I) and (II) forming a salt with (IV) ammonia or an amine; and
(D) about 0.001 to about 15% by weight of an emulsion stabilizing water-soluble salt distinct from component (C) represented by the formula

Abstract
This invention relates to an emulsified water-blended fuel composition comprising: (A) a hydrocarbon boiling in the gasoline or diesel range; (B) water; (C) a minor emulsifying amount of at least one fuel-soluble salt made by reacting (C)(I) at least one acylating agent having about 16 to 500 carbon atoms with (C)(II) ammonia and/or at least one amine; and (D) about 0.001 to about 15% by weight of the water-blended fuel composition of a water soluble, ashless, halogen-, boron-, and phosphorus-free, amine salt, distinct from component (C). In one embodiment, the composition further comprises (E) at least one cosurfactant distinct from component (C); in one embodiment, (F) at least one organic cetane improver; and in one embodiment, (G) at least one antifreeze. The invention also relates to a method for fueling an internal combustion engine comprising fueling said engine with the composition of the present invention.
