  • Alkyl esters of fatty acids in fuel microemulsions for the internal combustion engine and for oil furnaces
    Publication number: 20040098904
    Abstract: Alkyl esters of Fatty Acids such as methyl stearate are valuable renewable energy resources that can be used to replace in part petroleum products such as diesel oil and fuel oil for furnaces. Microemulsion fuels made by blending diesel oil at low shear with an Additive containing the ester result in stable compositions at sub-freezing temperatures and also, have advantages of good engine performance and abatement of pollution. Compositions of diesel oil/Additive plus Fatty Acids Esters at 95/05, 90/10, 80/20, 70/30 and 60/40 weight/weight were investigated. The utilization of the alkyl esters of the fatty acids depends on the particular unsaturated fatty acid used in the Additive, the fuel composition and the particular ester. Summaries in graph form show how several esters of fatty acids are used in the microemulsion fuels both for diesel oil used in the internal combustion engine and heating oil for furnaces.

  • Microemulsion fuel compositions for the internal combustion engine and for oil furnaces
    Patent number: 6017368
    Abstract: Low viscosity water-in-oil (W/O) microemulsion fuels, that are stable without any phase separation over a wide range of temperatures including temperatures below the freezing point of water, made by low shear mixing of petroleum products with an additive solution resulting in microemulsion fuels for the internal combustion engine and oil heating furnaces, either plant or home, with said microemulsion fuels having the unique features of enhancing the reduction of the oxides of nitrogen, reducing particulate matter such as smoke in the exhaust gases and flue gases, and neutralizing the sulfur acids derived from the oxidation of the sulfur in the petroleum product that occurs during combustion of the microemulsion fuel thereby resulting in the abatement of air pollution.

  • Clear and stable liquid fuel compositions for internal combustion engines
    Patent number: 4083698
    Abstract: A fuel composition, preferably for use in internal combustion engines, comprising a water-in-oil emulsion of (a) a hydrocarbon fuel, such as gasoline, diesel fuel or fuel oil; (b) water; (c) preferably a water-soluble alcohol; and (d) a novel combination of surface-active agents to provide a clear composition which is stable against phase separation over a wide range of temperatures.
