Patent number: 6589302Abstract: An additive concentrate for improving the lubricity of low sulfur fuels comprises an additive composition diluted in an aromatic solvent, said composition comprising the reaction product of a first glyceride possessing an unsaturated fatty acid content of at least about 40 mole %, based on the total weight of fatty acid present in the first glyceride, and an iodine number of greater than 35, a second glyceride possessing an unsaturated fatty acid content of less than about 20 mole %, based on the total weight of the fatty acids present in the second glyceride, and an iodine number of less than 35, and, at least one alkanolamine. The concentrate remains fluid and stable at low temperatures and, when added to low sulfur fuels, improves lubricity, enhances fuel economy and minimizes engine deposits.Type: GrantFiled: June 21, 2000Date of Patent: July 8, 2003Assignee: Texaco Inc.Inventors: Thomas F. DeRosa, Thomas Cangelosi, Serge A. Cryvoff, Frank J. DeBlase, Thomas E. Hayden, Benjamin J. Kaufman, James R. Ketcham, Michael Rawdon, Yvonne Thiel

Publication number: 20030061761Abstract: The invention relates to a fuel composition which comprises a diesel fuel, a C1-C4-alkyl ester of an &agr;-hydroxymonocarboxylic acid and, if appropriate a C1-C4-alcohol. The diesel fuel is either obtained from petroleum or from a petroleum fraction, such as a middle distillate, or is obtained by conversion of material of biological origin (so-called biodiesel). The fuel composition preferably contains from 3 to 6% by weight C1-C4-alkyl ester, calculated on the basis of the total weight of the composition.Type: ApplicationFiled: September 18, 2002Publication date: April 3, 2003Inventors: Gerrit Leendert Nanninga, Jan Van Breugel
