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（中）：
一种用于通过使用配制的油作为润滑油在用润滑油润滑的高压缩火花点火发动机中防止或减少发动机爆震或预点燃的方法。 配制的油具有含有至少一种具有至少约25％甲基形式的碳的支链烃或至少一种至少一种支链单羧酸的多元醇酯的组合物。 一种润滑发动机油，其具有包含至少一种具有至少约25％的甲基形式的碳的支链烃或至少一种至少一种支链单羧酸的多元醇酯的组合物。 润滑发动机油可用作乘用车发动机油（PVEO）产品。
