Patent ID: 8142524

Claim:
A diesel fuel composition comprising a fuel component and an additive component comprising a quantity of one or more epoxy-ester species having a general formula: wherein R 1 is selected from the group consisting of C1 to C3 alkyl moieties, R 3 is selected from the group consisting of C1 to C1O alkyl moieties and C1 to C1O alkenyl moieties, and R 2 is a molecular linkage comprising subunits and expressed as: —S 5 —S 4 —S 3 —S 2 —S 1 — wherein subunits S 1 , S 3 , and S 5 are independently selected from the group consisting of C1 to C6 alkyl moieties, C1 to C6 alkenyl moieties, C1 to C6 alkoxy moieties, the absence of any such subunit, and combinations thereof; and wherein subunits S 2 and S 4 are independently selected from the group consisting of epoxy moieties, C1 to C4 alkyl moieties, C1 to C4 alkenyl moieties, C1 to C4 alkoxy moieties, the absence of any such subunit, and combinations thereof; and wherein said one or more epoxy-ester species account for between 0.1 and 60 percent of the diesel fuel composition by weight.
