摘要： A method for preventing or reducing engine knock or pre-ignition in a high compression spark ignition engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition that contains at least one branched hydrocarbon having at least about 25% of the carbons in the form of methyl groups, or at least one polyol ester of at least one branched mono-carboxylic acid. A lubricating engine oil having a composition that contains at least one branched hydrocarbon having at least about 25% of the carbons in the form of methyl groups, or at least one polyol ester of at least one branched mono-carboxylic acid. The lubricating engine oils are useful as passenger vehicle engine oil (PVEO) products.

摘要： A method for preventing or reducing engine knock or pre-ignition in a high compression spark ignition engine lubricated with a lubricating oil by introducing to a combustion chamber of the engine from 0.1 to 5% by volume of the gasoline used a lubricating oil as a formulated oil, said formulated oil having a composition comprising (i) a major amount of a lubricating oil base stock comprising at least 80% by weight of one branched ester having at least 15% of the total carbons in the form of methyl groups, and (ii) a minor amount of at least one ashless amine phosphate antiwear additive. Also provided is a lubricating engine oil for high compression spark ignition engines including (i) a major amount of a lubricating oil base stock comprising at least 80% by weight formula I below: esterified (per —OH basis) with 25 to 100% isobutyric acid and 0 to 75% 3,5,5-trimethylhexanoic acid, wherein R is a H, methyl, ethyl, isopropyl, or isobutyl, and (ii) a minor amount of at least one amine phosphate ashless antiwear additive.

摘要： Naphtha boiling range compositions are provided that can have improved combustion properties (relative to the research octane number of the composition) in spark ignition engines and/or compression ignition engines. The improved combustion properties can be achieved by controlling the total combined amounts of n-paraffins and isoparaffins that include a straight-chain propyl group (R1—CH2—CH2—CH2—R2). For such a straight-chain propyl group, R2 can correspond to any convenient CxHy group that can appear in a paraffin or isoparaffin. R1 can correspond to a hydrogen atom, making the straight-chain propyl group a terminal n-propyl group; or R1 can correspond to any convenient CxHy group that can appear in a paraffin or isoparaffin.

摘要： A lubricant composition for high compression spark ignition engines that contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A method for preventing or reducing engine knock and pre-ignition in an engine lubricated with a formulated oil. The formulated oil has a composition including at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A fuel composition for high compression spark ignition engines that contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). A method for preventing or reducing engine knock and pre-ignition in an engine by using a fuel additive composition in a gasoline fuel composition. The fuel additive composition contains at least one bismuth-containing compound (e.g., a bismuth salt of a carboxylic acid). The lubricating oils of this disclosure are useful as passenger vehicle engine oil (PVEO) products.
