Definitions

  • This invention relates to improved lubricating oils having excellent characteristics in antiwear, especially in reducing wear of valve train system. It especially relates to internal combustion engine lubricating oils, and additives and additives mixtures employable for the preparation of such lubricating oils.
  • Automobile spark ignition and diesel engines have valve train systems, including valves, cams and rocker arms which present special lubrication concerns. It is extremely important that the lubricant, i.e. the engine oil, protects these parts from wear. Further, it is important for engine oils to suppress the production of deposits in the engines. Such deposits are produced from non-combustibles and incomplete combustibles of hydrocarbon fuels (e.g., gasoline, diesel fuel oil) and by the deterioration of the engine oil employed.
