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 |
20120042856 | EGR EQUIPPED DIESEL ENGINES AND LUBRICATING OIL COMPOSITIONS - Soot induced kinematic viscosity increase of lubricating oil compositions for diesel engines, particularly heavy duty diesel engines, equipped with EGR systems, particularly EGR systems operating in a condensing mode, can be ameliorated by addition of an alkylated phenothiazine compound. | 02-23-2012 |
20120103303 | MARINE ENGINE LUBRICATION - Trunk piston marine engine lubrication, when the engine is fueled by heavy fuel oil, is effected by a composition comprising a major amount of an oil of lubricating viscosity and a minor amount of one or more phenolic compounds comprising distilled cashew nut shell liquid or hydrogenated distilled cashew nut shell liquid. Asphaltene precipitation in the lubricant, caused by the presence of contaminant heavy fuel oil, is prevented or inhibited. | 05-03-2012 |
