Embodiment 1

[0028] Embodiment 1: Preparation of boron-containing aqueous precursor solution

[0029] 83.5 grams of ammonium pentaborate octahydrate (NH 4 B 5 o 8 -8H 2 O; mol wt544.3g / mole)) was added to 417.7 g of deionized water. Heat the mixture to 80°C with stirring until all the salt is dispersed. The solution remained clear at 80° C. and contained 1.8% by weight boron.

Embodiment 2

[0030] Embodiment 2: Preparation of boron-containing dispersion fluid

[0031] To 1200 grams of mineral oil base stock placed in a 4-liter Erlenmeyer flask was added 90 grams of Lubrizol 400A, a proprietary additive package containing a dispersant mixture and 180 grams of kerosene. The mixture was stirred at ambient temperature until a clear solution was obtained. 166.0 g of the boron-containing aqueous precursor dispersion prepared in Example 1 was added to the oil solution. The two solutions were mixed together using a high speed hand mixture to form a water-in-oil emulsion. The emulsion was transferred to a 3 liter round bottom flask equipped with a stirrer and Dean-Stark trap with condenser. The mixture was heated to a maximum of 150°C over a period of about 1 hour with stirring to remove water. A dispersion of boron salts in an oil base is formed. The final water content was 6,480 ppm and the final boron theoretical content was 1,827 ppm.

Embodiment 3

[0032] Embodiment 3: Preparation of boron-containing two-stroke engine fuel treatment agent

[0033] Lubricating oil suitable for dilution with gasoline and used as fuel for two-stroke engines was prepared by the following steps: the boron-containing dispersion fluid of Example 2 was mixed with Tufflo 6036, an additive containing various detergents and dispersants with independent intellectual property rights The package was mixed to achieve a final boron content of approximately 300 ppm. Fuel was then added to the mixture in a 50:1 ratio to provide a final boron content of about 6 ppm.

Abstract

The present invention provides a fuel additive and a method of using and preparing the fuel additive. The fuel additive comprises a non-acidic boron-containing salt in a carrier fluid. The fuel additive enhances combustion by improving fuel efficiency or reducing pollutants in exhaust gases formed by combustion of the fuel and the fuel additive.

Description

[0001] related application [0002] This application is related to and claims priority to and benefit from U.S. Patent Provisional Application Serial No. 60 / 673,907, filed April 22, 2005, entitled "Hydrocarbon Fuel Additives Comprising Non-Acidic Inorganic Boron Compounds and Related Methods , which is incorporated herein by reference in its entirety. [0003] Technical Field of the Invention [0004] The present invention relates to the field of fuel additives, in particular to boron-containing hydrocarbon fuel additives for enhancing efficiency and / or reducing pollution. Background of the invention [0005] A variety of hydrocarbon fuels are currently in use, each with its advantages and disadvantages. Examples of such fuels include gasoline, natural gas, diesel, kerosene, jet fuel, LPG, heavy distillates, bunker fuel, ethanol, coal, other solid hydrocarbon fuels, and the like. Over the past hundred years, chemical compounds have been used as fuel additives to improve var...
