Abstract:
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.
Abstract:
Processes for the manufacture of metal complex grease compositions are provided. In one embodiment, the process comprises: preparing a slurry comprising a base oil, water, a metal base and a complexing agent, wherein the weight ratio of water:solid in the slurry is in the range of from 0.15:1 to 1.5:1; applying shear to the slurry; adding a C10-C24 saturated or unsaturated fatty acid or derivative thereof to effect a saponification reaction; removing water from the saponified product; heating the saponified product at a temperature in the range of from 190 to 230° C.; and subsequently cooling the product to a temperature in the range of from 200 to 150° C. to form the metal complex grease composition.
Abstract:
A lubricating oil composition for metal working, including a base oil composed of one or more selected from mineral oils and synthetic oils and having a kinematic viscosity at 40° C. of 50 to 300 mm2/s, and 0.01 to 10% by mass, based on the total amount of the composition, of a glycerin derivative (A) represented by general formula (I) [wherein R1 represents an alkyl group, alkenyl group or arylalkyl group, R2 and R3 each independently represent a hydrogen atom or a methyl group, A1O and A2O each independently represent an oxyalkylene group, n is 0, 1 or 2, p and q each represent the average number of added moles, and p+q is a value of 0 to 5] is used to provide a lubricating oil composition for metal working which can improve metal workability and suppress the generation of metal abrasion powder and surface damage when used in working of a metal or an alloy thereof, in particular, in deep drawing of a non-ferrous metal such as aluminum or an aluminum alloy and therefore enables the production of a product with high surface quality.
Abstract:
A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules. Each lubricant additive molecule includes a surface active group attractable to a target surface, and a carbon containing component connected to the surface active group, for providing a carbon source to form a carbon film on the target surface. A method for in situ forming of a carbon film using the lubricant composition, includes adding the lubricant composition into a target machine such that the lubricant composition is in contact with a target surface of the target machine, and operating the target machine to cause a temperature and a pressure at the target surface so that the carbon containing component is unraveled thereon to form a carbon film on the target surface during the operation.
Abstract:
The use of an oil-soluble mono-, di-, or tri-glyceride of at least one hydroxy polycarboxylic acid, or a derivative thereof, as an anti-wear additive and/or friction modifier in a non-aqueous lubricant composition and/or in a fuel composition. Also, a non-aqueous lubricant composition and a fuel composition for an internal combustion engine which comprise at least one additive which is an oil-soluble mono-, di-, or tri-glyceride of at least one hydroxy polycarboxylic acid, or a derivative thereof.
Abstract:
The waterproof grease composition of the present application comprises a base oil that comprises at least one of mineral oil and synthetic oil and having a kinematic viscosity of from 10 to 400 mm2/sec at 40° C., a thickener, and a waterproofness-imparting agent selected from surfactant, metal soap, fluorine-containing water repellent, silicone-type water repellent, pH-controlling agent, wax, polymer and graphite. Accordingly, it may prevent peeling such as white structure peeling even when water is mixed therein.The wheel-supporting roller bearing of the invention comprises an inner member having a raceway surface in the outer peripheral surface thereof, an outer member having, in the inner peripheral surface thereof, a raceway surface that faces the raceway surface of the inner member and disposed outside the inner member, and plural rolling elements rollably disposed between the two raceway surfaces, and which contains the above waterproof grease composition sealed therein; and this has excellent waterproofness.
