Abstract

A diesel fuel and additive mixture is useful for reducing particulate matter emissions while improving or at least not aggravating oxidative stability during combustion. The additive includes at least one compound having a general formula selected from the group consisting of:

and

combinations thereof, wherein: R is a saturated or unsaturated hydrocarbon having from about 1 to about 6 carbons. The additive is effective in diesel at concentrations as low as from about 50 to about 1000 ppm by weight.

First claim

What is claimed is:

1. A diesel fuel comprising diesel fuel including an additive, the additive comprising a compound having a general formula selected from the group consisting of:

and combinations thereof, wherein:
R is a saturated or unsaturated hydrocarbon having from about 1 to about 6 carbons; and
the additive is present in diesel fuel at a concentration of from about 50 to about 1000 ppm by weight.

2. The diesel fuel of claim 1 wherein R has from about 2 to about 5 carbons.

3. The diesel fuel of claim 2 wherein R has from about 3 to about 4 carbons.

4. The diesel fuel of claim 1 wherein the additive additionally comprises a compound having the general formula:

wherein R 1 and R 2 are the same or different and are a saturated hydrocarbon having from about 1 to about 6 carbons.

5. The diesel fuel of claim 4 wherein R 1 and R 2 are the same.

6. The diesel fuel of claim 1 wherein R is a methyl group.

7. The diesel fuel of claim 1 wherein R is an ethyl group.

8. The diesel fuel of claim 1 wherein the additive additionally comprises diethyl carbonate.

9. The diesel fuel of claim 1 wherein the additive additionally comprises ethyl methyl carbonate.

10. The diesel fuel of claim 1 wherein the additive is present at a concentration of from about 100 to about 750 ppm by weight.

11. The diesel fuel of claim 10 wherein the additive is present at a concentration of from about 300 to about 600 ppm by weight.
