Fuel composition with lubricity additives
A fuel composition comprising a fuel and a lubricity additive where the lubricity additive is selected from (1) 1-Lauroyl-rac-glycerol, (2) Dodecanamide, N-hydroxy-, or (3) 2-Ethylhexanoic acid and the fuel is gasoline.
1. A fuel composition comprising:
a base fuel wherein the base fuel is a blend of gasoline and ethanol wherein the base fuel comprises from 10% by volume to 85% by volume of ethanol;;
from 25 ppm to 100 ppm by weight of a lubricity additive, based on the total weight of the fuel composition;
wherein the lubricity additive consists of 1 -Lauroyl-rac-glycerol and wherein the lubricity additive is soluble in the fuel.
2. The fuel composition according to claim 1 , wherein the fuel composition has a friction coefficient ranging from 0.390 to 0.500 as measured according to ASTM D6079-11.
3. The fuel composition according to claim 1 , wherein the fuel composition has a wear scar diameter ranging from 755 μm to 795 μm as measured according to ASTM D6079-11.
4. A method for improving lubricity of a fuel composition, providing a base fuel wherein the base fuel is a blend of gasoline and ethanol wherein the base fuel comprises from 10% by volume to 85% by volume of ethanol;
adding from 5 ppm to 100 ppm by weight, based on the total weight of the fuel composition, of a lubricity additive to the base fuel to produce the fuel composition;
wherein the lubricity additive consists of 1-Lauroyl-rac-glycerol and wherein the lubricity additive is soluble in the fuel.
5. A method for improving fuel performance of a direct injection engine the method comprising,
fueling the direct injection engine with a fuel composition comprising a base fuel wherein the base fuel is a blend of gasoline and ethanol wherein the base fuel comprises from 10% by volume to 85% by volume of ethanol; and from 5 ppm to 100 ppm by weight of a lubricity additive, based on the total weight of the fuel composition; and
operating the direct injection engine;
wherein the lubricity additive consists of 1-Lauroyl-rac-glycerol and wherein the lubricity additive is soluble in the fuel.
6. The fuel composition according to claim 1 , wherein the base fuel comprises from 15% to 90% by volume of gasoline.
