| 20090011966 | Lubricating Oil Composition - A lubricating oil composition having a total base number of more than 15 mg KOH/g, as determined by ASTM D2896, and including at least 40 mass % of an oil of lubricating viscosity; at least one detergent; and at least one compound of the formula (I) and/or formula (II): | 01-08-2009 |
| 20090156448 | Additive Compositions - Compositions in the form of lubricating oil compositions, greases, fuels or functional fluids containing, in the form of Michael adducts, N-substituted phenylenediamine additives in which at least one of the substituents on the N atoms carries a carbonyl group that is connected to an alkyl, alkoxyalkyl, or alkylthioalkyl group either directly or via an oxygen atom. | 06-18-2009 |
| 20090171031 | Method of Forming Polyalkene Substituted Carboxylic Acid Compositions - The residual chlorine content of a polyolefin-substituted carboxylic acylating agent formed by a halogen-assisted reaction of a polyalkene and at least one olefinic, monounsaturated mono- or dicarboxylic acid, anhydride or ester, is reduced when the reaction is conducted in the presence of a controlled amount of a metal compound. | 07-02-2009 |
| 20090203559 | Engine Lubrication - A trunk piston or cross-head diesel engine having a centrifuge system including a sealing medium is lubricated with a lubricant which, for the cross-head engine, is a system lubricant and which contains 0.04 to 5 mass %, expressed as active ingredient, of a combination of one or more linked aromatic compounds and one or more nitrogen containing ashless disperants, in a mass:mass ratio in the range of 1:3 to 9:1. | 08-13-2009 |
| 20090291871 | Lubricating Oil Compositions - A lubricating oil composition formulated with a viscosity index (VI) improver composition including a combination of an ethylene α-olefin copolymer having no greater than 66 mass % of units derived from ethylene, and a linear diblock copolymer including at least one block derived primarily from a vinyl aromatic hydrocarbon monomer, and at least one block derived primarily from diene monomer. | 11-26-2009 |
| 20100160195 | Aniline Compounds as Ashless TBN Sources and Lubricating Oil Compositions Containing Same - Aniline compounds useful as ashless TBN sources for lubricating oil compositions that are compatible with fluoroelastomeric engine seal materials, and lubricating oil compositions containing such aniline compounds. | 06-24-2010 |
| 20100173811 | ADDITIVES AND LUBRICATING OIL COMPOSITIONS CONTAINING SAME - Para-alkylated substituted diphenylamines are made by catalytically alkylating diphenylamine with a branched-chain alkene, such as propene, oligomer mixture in which the oligomer present in the greatest percentage has 15-24 carbon atoms. The alkylated diphenylamines are useful crankcase lubricant additives such as for reducing piston deposits and engine sludge. | 07-08-2010 |
| 20100286414 | Soot Dispersants and Lubricating Oil Compositions Containing Same - Linked aromatic compounds found to act as potent soot dispersants in lubricating oil compositions; lubricating oil compositions containing such soot dispersants and precursor compounds from which the soot dispersants are derived. | 11-11-2010 |
| 20110105372 | Lubrication and Lubricating Oil Compositions - Tetra-alkylated phenylenediamine compounds useful as ashless TBN sources for lubricating oil compositions that are compatible with fluoroelastomeric engine seal materials and meet copper corrosion requirements, and lubricating oil compositions containing such phenylenediamine compounds. | 05-05-2011 |
| 20110105374 | Lubrication and lubricating oil compositions - Monoaryltrialkyl phenylenediamine compounds useful as ashless TBN sources for lubricating oil compositions that are compatible with fluoroelastomeric engine seal materials and meet copper corrosion requirements, and lubricating oil compositions containing such phenylenediamine compounds. | 05-05-2011 |
