Abstract

The invention discloses a combined energy-conserving synergistic agent composition of lubricating oil nanometer material, which is prepared by the following raw materials according to mass percent: 30-85 percent of nanometer-hydrocarbon particles, 3.0-30 percent of nanometer-copper particles, 3.0-30 percent of auxiliary antioxidant, and 3.0-30 percent of emulsion inhibitor. The invention adopts the optimized combination of multiple nanometer particles and adds the auxiliary antioxidant and the emulsion inhibitor to the optimized combination, meanwhile makes full use of the cooperation action between the additives and improves the lubricating oil performance in lubrication, detergent dispersion, anti-oxidation and anti-emulsification performance. The combined energy-conserving synergistic agent composition of lubricating oil nanometer material is added to the lubricating oil of the M-TCE engine to start an engine bench comparative test; the result indicates that the external characteristic power of the engine is increased, the effective specific fuel consumption is decreased averagely by 2.6 percent, and the load characteristic effective specific fuel consumption is averagely decreased by 2.8 percent; under the high-idle-speed working condition, the CO content is decreased from 0.03 percent to 0.02 percent and the HC content is decreased from 12ppm to 9ppm; under the idle-speedworking condition, the CO content is decreased from 0.05 percent to 0.04 percent and the HC content is decreased from 25ppm to 18ppm.

Description

technical field [0001] The invention belongs to the technical field of improving specific physical properties or chemical properties with additives characterizing lubricating oil compositions, and in particular relates to a lubricating oil nanomaterial composite energy-saving synergist composition. Background technique [0002] Energy saving and emission reduction has become the current theme, and equipment lubrication and energy saving, which has been neglected by people, are gradually being paid attention to by people. Nanoparticles have unique properties such as surface effect, quantum size effect, volume effect, and macroscopic quantum tunneling effect. When some nanoparticles are added to lubricating oil, they have an unexpected anti-friction and anti-wear effect on friction pairs. With the deepening of research, more and more nanoparticles have been found to have excellent properties in anti-friction and anti-wear, and nano-particle anti-wear additives have also become...
