Abstract:
     The invention provides an additive to increase lubricity and antifrictionability of lubricating oil, suitable especialy for lubrication systems of internal combustion engines such as diesel engines, gasoline engines, etc. With lubricating oil as the carrier, teflon dispersion liquid and polyethylene glycol type and polyhydric alcohol type non-ionic surface active agent and polymethacrylate viscosity index improving agent, etc. are added and mixed to abtain the product. It can form on the surface ofcomponent parts of internal combustion engines an extremely stable and smooth solid protection film. It can not only increase antifrictionability, decrease wear of cylinde sleeve by 82%, prolong service life of engines, and decrease oil consumption, oil-saving efficiency attaining 2-5%, but also is superior in performance to the imported antifriction additives, such as TMT etc.
