Methods to improve lubricity of fuels and lubricants
A method for providing lubricity in fuels and lubricants includes adding a boron compound to a fuel or lubricant to provide a boron-containing fuel or lubricant. The fuel or lubricant may contain a boron compound at a concentration between about 30 ppm and about 3,000 ppm and a sulfur concentration of less than about 500 ppm. A method of powering an engine to minimize wear, by burning a fuel containing boron compounds. The boron compounds include compound that provide boric acid and/or BO 3 ions or monomers to the fuel or lubricant.
1. A composition, comprising a diesel fuel, lubricant and a boron compound wherein the boron compound is present as a nanometer-sized powder at a concentration of from about 30 to about 3000 ppm,
wherein,
the fuel has a sulfur concentration of less than about 500 ppm; and
the boron compound is selected from the group consisting of a trialkylborate, a boroxin, or a combination thereof.
2. The composition of claim 1 , wherein the boron compound is selected from the group consisting of trimethylborate, trimethoxyboroxin, and combinations thereof.
3. The composition of claim 1 , wherein the lubricant is selected from mineral oils, vegetable oils, synthetic oils, greases, and combinations thereof.
