发动机润滑剂辛烷提高以平息时而发生的预点火
摘要：
一个实施例提供一种具有发动机油和溶解在发动机油中的添加剂的发动机润滑剂，该添加剂的量有效平息由于润滑剂进入发动机的燃烧室导致的预点火或者爆震。所述添加剂具有在370K低于300托的饱和蒸汽压力，并且只产生挥发性的燃烧产物。另一个实施例提供一种平息由于发动机润滑剂进入发动机的燃烧室导致的预点火或者爆震的方法，其基于在发动机润滑剂中加入具有在370K低于300托的饱和蒸汽压力并且只产生挥发性的燃烧产物的芳香族含氮化合物。
摘要（英）：

One embodiment provides an engine lubricant having an engine oil and an additive dissolved in the engine oil in an amount effective to quiet pre-ignition or knock due to ingress of the lubricant into a combustion chamber of an engine. The additive has a saturated vapor pressure less than 300 Torr at 370 Kelvin, and yields only volatile combustion products. Another embodiment provides a method to quiet pre-ignition or knock due to ingress of engine lubricant into a combustion chamber of an engine, based on adding into the engine lubricant an aromatic, nitrogen-containing compound having a saturated vapor pressure less than 300 Torr at 370 Kelvin, and yielding only volatile combustion products.
