20080319216 | Salt of a Sulfur-Containing, Phosphorus-Containing Compound, And Methods Thereof - There is disclosed a salt of a sulfur-containing, phosphorus-containing compound. There is also disclosed a method of making the salt. | 12-25-2008 |
20090048131 | LUBRICATING COMPOSITIONS HAVING IMPROVED FRICTION PROPERTIES - The present invention provides an additive composition comprising (a) at least one ash-containing phosphorus compound prepared by a primary or secondary alcohol or mixtures thereof, and (b) a salt of at least one hydrocarbylamine and at least one hydrocarbyl acid phosphate. Further, the present invention provides a lubricating composition comprising (a) at least one ash-containing phosphorus compound prepared by a primary or secondary alcohol or mixtures thereof, and (b) a salt of at least one hydrocarbylamine and at least one hydrocarbyl acid phosphate, and methods of use thereof. | 02-19-2009 |
20090111722 | ENGINE WEAR PROTECTION IN ENGINES OPERATED USING ETHANOL-BASED FUEL - Lubricant formulations and methods for producing lubricant formulations are described that provide improved wear protection in engines operated using ethanol-based fuels. The improved wear protection may be provided by an increased amount of overbased calcium detergent present in the formulation. | 04-30-2009 |
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 |
20100144563 | ADDITIVES AND LUBRICANT FORMULATIONS FOR IMPROVED ANTIWEAR PROPERTIES - Lubricated surfaces and lubricant compositions for lubricating a surface. The lubricated surface is provided by a lubricant composition including a base oil of lubricating viscosity, at least one metal salt of phosphorothioic acid, and an ashless, sulfur-free organophosphorus compound providing a metal to phosphorus weight ratio ranging from about 0.25:1 to about 1.0:1 by weight. The lubricant composition is substantially devoid of molybdenum. | 06-10-2010 |
20100204073 | ENGINE WEAR PROTECTION IN ENGINES OPERATED USING ETHANOL-BASED FUEL - Lubricant formulations and methods for producing lubricant formulations are described that provide improved wear protection in engines operated using ethanol-based fuels. The improved wear protection may be provided by an increased amount of overbased calcium detergent present in the formulation. | 08-12-2010 |
