  • Method for making a fuel for a modified spark ignition combustion engine, a fuel for a modified spark ignition combustion engine and a fuel additive for a conventional spark ignition combustion engine
    Patent number: 7323020
    Abstract: A method of making a fuel composition for a modified internal combustion spark ignition engine comprising combining a fuel grade ethanol, an oxygen-containing component and at least one C6-C12 hydrocarbon. A fuel produced by such a method is also provided.
    Type: Grant
    Filed: December 15, 2003
    Date of Patent: January 29, 2008
    Inventors: Angelica Hull, Igor Golubkov
  • Method of reducing the vapor pressure of ethanol-containing motor fuels for spark ignition combustion engines
    Patent number: 6761745
    Abstract: A method of reducing the vapor pressure of a C3 to C12 hydrocarbon-based motor fuel mixture containing 0.1 to 20% by volume of ethanol for conventional spark ignition internal combustion engines, wherein, in addition to an ethanol component (b) and a C3 to C12 hydrocarbon component (a), an oxygen-containing additive (c) selected from at least one of the following types of compounds: alcohol other than ethanol, ketone, ether, ester, hydroxy ketone, ketone ester, and a heterocyclic-containing oxygen compound in an amount of at least 0.05 by volume of the total fuel and at least one C6-C12 hydrocarbon (d) are used in the fuel mixture, is disclosed. A mixture of fuel grade ethanol (b), oxygen-containing additive (c) and C6-C12 hydrocarbon (d) usable in the method of the invention is also disclosed.
