摘要:
A method for preventing or reducing low speed pre-ignition in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and at least one boron-containing compound, as a minor component. The at least one boron-containing compound includes at least one borated dispersant, or a mixture of a boron-containing compound and a non-borated dispersant. A lubricating engine oil having a composition including a lubricating oil base stock as a major component, and at least one boron-containing compound, as a minor component. The lubricating oils of this disclosure are particularly advantageous as passenger vehicle engine oil (PVEO) products.
摘要:
The present invention is directed to a method for improving one or more of the control of deposit formation and friction in an engine lubricated using a lubricating oil comprising a base oil and additives by employing as the additive the necessary combination of a borated hydroxyl saturated hydrocarbyl ester amide-amine mixture, zinc dialkyl dithiophosphate, and metal salicylate detergent, the deposit formation and friction being improved as compared to a lubricating oil containing the borated hydroxyl saturated hydrocarbyl ester amide-amine mixture, zinc dialkyl dithiophosphate and a detergent other than metal salicylate, such as metal phosphate and/or metal sulfonate.
摘要:
This invention relates to a composition, comprising: an unsaturated functionalized monomer of from about 5 to about 30 carbon atoms, which is: (a) polymerized to form a functionalized polymer; (b) copolymerized with a comonomer to form a functionalized copolymer; or (c) reacted with an enophilic reagent to form a polyfunctionalized monomer. The polyfunctionalized monomer may be polymerized to form a polyfunctionalized polymer which may be further reacted with one or more additional reagents. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and polymeric resins.
摘要:
The present invention provides a grease composition or a lubricating oil composition which is capable of effectively preventing hydrogen brittleness-caused peeling from occurring on a rolling surface of a rolling bearing, is excellent in durability in a high temperature and speed operation, and can be used for a long time. A grease-packed bearing (1) has an inner ring (2), an outer ring (3), and a plurality of rolling elements (4). A sealing member (6) for sealing a grease composition (7) is provided at openings (8a) and (8b) disposed at both axial ends of the inner ring (2) and the outer ring (3). The grease composition (7) includes a base grease composed of a base oil and a thickener and an additive added to the base grease. The additive contains at least one compound selected from among plant-derived polyphenolic compounds and compounds formed by decomposition thereof. The above-described compounds include tannin, gallic acid, ellagic acid, chlorogenic acid, caffeic acid, curcumin, quercetin, and quinic acid.

摘要:
This invention is a composition that includes a transesterified fatty acid ester resulting from the reaction of a fatty acid ester, in the presence of an acid, with a hydroxyl-containing compound. The fatty acid esters of the invention are selected from those with a carbon number of eight to twenty. The hydroxyl-containing compound is an alcohol having a carbon number between one and eighteen. The resulting composition is useful as a lubricant, as a heat transfer agent, as a rheological modifier and as a corrosion/moisture inhibitor, among other uses.
摘要:
An extreme pressure agent and a friction coefficient modifier which comprises a compound having, in a molecule, a group represented by general formula (I): wherein R1, R2, and R3 each represents hydrogen atom or methyl group, and at least one of R2 and R3 represents hydrogen atom; a fluid resistant to seizure under load and a wear resistant fluid which each comprises the above additive or the above modifier; and a flame resistant fluid which comprises a thermally polymerizable substance, preferably the above compound. The extreme pressure agent and the friction coefficient modifier have excellent properties and are advantageously used for lubricating oil, metal working oil, and hydraulic oil. The flame resistant fluid suppresses vaporization of flammable substances by thermal polymerization to prevent fire when the fluid is exposed to a high temperature and is advantageously used as lubricating oil, metal working oil, hydraulic oil, heat treatment oil, and grease.
摘要:
It is disclosed that succinic acid and its derivatives that contain a branched aliphatic group on the 2 or alpha position of succinic acid form surfactants that exhibit a high order of or bioresistance to bacteriological degradation. Further, it has been discovered that these novel surfactants can be employed to prepare novel oil-in-water emulsions with lube oils such as mineral oil that are effective as cutting fluids for machining operations but provide an improved resistance to biodegradation to the cutting oil so formulated, without resorting to the inclusion of conventional biocides in the formulation. It has also been discovered that the bioresistance of the cutting fluid emulsion formulation can be further enhanced by using a branched aliphatic hydrocarbon oligomer or polymer as the lubricative component in the formulation. Cutting fluid emulsions so formulated are effective fluids in prolonging tool life and facilitating machining operations.
