    摘要： A lubricant composition for improved phosphorus retention of a used oil and a method for decreasing catalyst deactivation in a catalytic system for an engine exhaust. The lubricant composition is provided by a base oil and an additive composition that contains a phosphorus-containing additive mixture. The phosphorus-containing additive mixture includes an ash-containing phosphorus compound and an ash-free phosphorus compound. A phosphorus retention value provided by the lubricant composition is greater than about 85 percent after oil aging based on an amount of phosphorus initially present in the lubricant composition.

    摘要： Different zinc dialkyldithiophosphate (ZDDPs) exhibit different volatilities and have different effects on automotive emissions control catalysts. The ZDDPs and their respective decomposition fragments that have low volatility will have a correspondingly lower detrimental effect on combustion emissions control systems, because there are simply fewer phosphorous atoms that will pass through the combustion system to reach the emissions control system. Specifically, it has been discovered that ZDDPs that contain a significant fraction of MIBC ZDDP exhibit significantly lower volatility than other ZDDPs.

    摘要翻译： 不同的二烷基二硫代磷酸锌（ZDDP）表现出不同的挥发性，对汽车排放控制催化剂具有不同的影响。 具有低挥发性的ZDDP及其各自的分解片段将对燃烧排放控制系统具有相应较低的不利影响，因为通过燃烧系统将仅有较少的磷原子到达排放控制系统。 具体地说，已经发现含有显着部分MIBC ZDDP的ZDDP显示出比其他ZDDP显着降低的挥发性。

    摘要： A method and compositions for lubricating surfaces with lubricating oils exhibiting increased phosphorous retention. The lubricated surface includes a lubricant composition containing a base oil of lubricating viscosity, an amount of a phosphorus-containing compound and an amount of at least one hydrocarbon soluble titanium compound that is effective to provide an aged catalyst temperature that converts at least fifty percent of exhaust gas hydrocarbons, carbon monoxide, and NOx that is lower than an aged catalyst temperature that converts at least fifty percent of exhaust gas hydrocarbons, carbon monoxide, and NOx of the lubricant composition devoid of the hydrocarbon soluble titanium compound.
