摘要:
A lubricating oil comprises a major amount of a base oil and a minor amount of an additive package, and the additive package comprises one or more friction modifiers of formula I: where R is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl having 8 to 22 carbon atoms or R is represented by: and R 1 is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl having 8 to 22 carbon atoms and R 2 is hydrogen or a hydrocarbyl having 1 to 2 carbon atoms; or one or more friction modifiers comprising the reaction product of an aliphatic carboxylic acid and an amino hydroxy compound. Methods of using the lubricating oil to improve thin film and/or boundary layer friction in an engine are also disclosed.
摘要:
A grease composition comprising a major proportion of a grease, a hydroxy-containing soap thickener and a minor amount of a boronated oxazoline compound is disclosed. The hydroxy-containing soap thickener and boronated oxazoline compound are each added in amounts sufficient to increase the dropping point of the grease an appreciable amount. Generally this can be an increase of at least 8°C (15°F) and could be as great as 111° to 139°C (200°F to 250°F) or more. Sulfur and phosphorus compounds can also be incorporated into the compositon.
摘要:
The present invention addresses the problem of providing an aqueous coating agent composition (in particular, an aqueous lubricating film paint composition that includes a solid lubricant) that suppresses the interaction of a curable resin and a surfactant, suppresses thickening/disproportionation throughout an aqueous coating agent, has superior overall fluidity, coating properties, and storage stability, and can form a favorable coating film, along with the problem of providing a member provided with said coating film, as well as a method for forming said coating film. Said problems can be solved by an aqueous coating agent composition that includes (A) a curable resin in the form of an aqueous emulsion, (B) a surfactant, (C) solid particles, (D) one or more nitrogen-containing heterocyclic compounds, and (E) water. In particular, the component (C) preferably includes a solid lubricant, and for reasons of environmental regulations, it is particularly preferable that the component (D) be 1,3-dimethyl-2-imidazolidinone.

摘要:
The present invention relates to a lubricating composition comprising an oil of lubricating viscosity and 0.01 wt % to 10 wt % of a heterocycle having a hydrocarbyl group containing 6 to 40 carbon atoms, wherein the heterocycle is selected from the group consisting of: (i) an ester-containing heterocycle; (ii) an amide-containing heterocycle, and wherein the heterocycle is pyridine. The invention further provides for a method of supplying an internal combustion engine with the lubricating composition.
