Diane M. Dillon has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hydrocarbon fuel composition containing carbonate additive
    Patent number: 4891049
    Abstract: Hydrocarbon fuels heavier than gasoline, especially diesel fuel compositions, contain carbonate additives, preferably non-aromatic, metals-free carbonates, to reduce particulate emissions therefrom when combusted in an internal combustion engine.
    Type: Grant
    Filed: December 20, 1985
    Date of Patent: January 2, 1990
    Assignee: Union Oil Company of California
    Inventors: Diane M. Dillon, Ross Y. Iwamoto
  • Composition for cetane improvement of diesel fuels
    Patent number: 4740215
    Abstract: Liquid hydrocarbon fuels, especially diesel fuels, are admixed with diesters of oxalic acid to produce liquid hydrocarbon fuel compositions having improved ignition quality and enhanced cetane numbers.
    Type: Grant
    Filed: January 27, 1987
    Date of Patent: April 26, 1988
    Assignee: Union Oil Company of California
    Inventors: Diane M. Dillon, Peter J. Jessup
  • Cetane number
    Patent number: 4738686
    Abstract: Hydrocarbon fuels with an improved cetane number are obtained by blending a liquid fuel with a cyclic ether compound. Cyclic ethers are compounds which have a ring structure of carbon and a minor number of oxygen atoms, including beta-lactones and adducts of the beta-lactones with aldehydes or ketones.
    Type: Grant
    Filed: December 22, 1986
    Date of Patent: April 19, 1988
    Assignee: Union Oil Company of California
    Inventors: Diane M. Dillon, Peter J. Jessup
  • Cetane number improvement
    Patent number: 4723964
    Abstract: Liquid hydrocarbon fuels having an enhanced cetane number include at least one azo compound having the formula:R.sub.1 N.dbd.NR.sub.2wherein R.sub.1 and R.sub.2 are the same or different organo groups, each containing 1 to about 10 carbon atoms.
    Type: Grant
    Filed: December 20, 1985
    Date of Patent: February 9, 1988
