摘要:
A composition useful as a lubricant for an automatic transmission comprises an oil of lubricating viscosity and a condensation product of an aromatic polycarboxylic acid or mixtures thereof or a reactive equivalent thereof, having at least two carboxylic groups situated so as to permit formation of a cyclic imide having 5 or 6 atoms in said cyclic structure; with an aliphatic primary amine or alcohol, containing 6 to 60 carbon atoms.
摘要:
The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and friction modifiers that contain one or more amide functional groups, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.

The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and friction modifiers derived from hydroxy-carboxylic acids, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.
摘要:
This invention relates to compositions and methods for inhibiting corrosion and deposit formation in fuel handling equipment, with reduced or eliminated incidence of fuel filter plugging and internal diesel injector deposits (IDID) in the equipment that eventually employs the final commercially blended form of the fuel. More specifically, the invention relates to inhibiting corrosion from the walls of fuel pipelines and storage equipment and preventing deposits in engines.
