20100056407 | LUBRICANT FORMULATIONS AND METHODS OF LUBRICATING A COMBUSTION SYSTEM TO ACHIEVE IMPROVED EMMISIONS CATALYST DURABILITY - 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. | 03-04-2010 |
