  • Use of an amide to reduce lubricant temperature
    Patent number: 6759375
    Abstract: A sump-lubricated internal combustion engine equipped with exhaust gas recycle, lubricated with (a) an oil of lubricating viscosity, (b) 0.05 to 1 percent by weight of an amide of an aliphatic carboxylic acid, and (c) at least one additional dispersant, detergent, or anti-wear agent, exhibits reduced temperature of the lubricant in the sump.
    Type: Grant
    Filed: May 23, 2002
    Date of Patent: July 6, 2004
    Assignee: The Lubrizol Corporation
    Inventors: Thomas T. Curtis, Ewa A. Bardasz, Daniel H. Heath, Peter B. Thomson
  • Emulsified water fuel blend containing an aqueous organic ammonium salt
    Publication number: 20040020105
    Abstract: The invention relates to an emulsified water fuel blend containing aqueous organic ammonium salts. The emulsified water fuel blend lowers nitrogen oxide emissions from engines.

  • On-board rotational viscometers
    Patent number: 6412338
    Abstract: A viscometer for sensing or characterizing the stress required to shear a fluid at a given rate includes a pair of members coaxially mounted for relative rotation. Between the members is an annular gap defining a flow path for the fluid. The flow path is configured such that during differential rotation of the members, fluid is caused to flow through the annular gap that is a function of the differential rotation and the viscosity of the fluid. A sensor measures the torque or torque equivalent required to achieve such differential rotation between the members.
