Embodiment 1

[0029] Antiwear agent: FeS 2 / Preparation of carbon composite materials;

[0030] FeS 2 Preparation of carbon composite materials as lubricating oil additives and anti-wear agents

[0031] The first step: carbon preparation. Dissolve 5g of PEI (polyetherimide) in 15ml of deionized water, stir, transfer to a one-necked bottle after it is completely dissolved, and continue to stir for later use; add 2.4g of bromoacetonitrile into 10ml of ethanol, stir until dissolved; use a dropper to The mixture of bromoacetonitrile and ethanol was slowly added dropwise to the PEI solution, stirred for 36 hours, rotary evaporated at 45°C, washed with ether, and dried in vacuum. Denoted as precursor PEI. Take AgN(CN) with a molar ratio of 1:1 to the precursor PEI material 2 Add it to 5g of precursor material, add water and stir for 12 hours, labeled PEI-DCA, spin evaporate, wash, and vacuum dry. Put PEI-DCA material into tube furnace N 2 Burn to 800°C under atmosphere to obtain the desir...

Abstract

The invention relates to composite antioxidant and anti-wear lubricating oil for a gasoline engine. According to the composite antioxidant and anti-wear lubricating oil, a FeS2 / carbon composite nanomaterial serves as a lubricating oil anti-wear additive, sulfonate and salicylate are adopted to improve the cleaning property, molybdenum dialkyldithiocarbamate (MoDTC ) and a phenol ashless antioxidant serve as antioxidants, in addition, the high-and-low temperature performance is improved by adding a high-molecular polymer, an optimized composite additive has excellent performance, and the consumption of fuel is reduced by about 16-20%; and the result shows that a lubricant with the optimized proportion can be provided for the high-efficiency economical engine, and for a vehicle manufacturerand a user, the lubricating oil can be the proper direction for inhibiting the cost of the engine fuel and the durability of the engine under different operating conditions.

Description

technical field [0001] The invention relates to the preparation of a composite lubricating oil additive, in particular to the application of a gasoline engine lubricating oil additive, and the performance test of the composite lubricant for improving gasoline engine efficiency and fuel economy is done. Background technique [0002] With the increasing concern on energy shortage and environmental protection, transportation vehicles account for about 19% of the world's energy consumption every year. Friction between surfaces is the main cause of energy dissipation in a car engine. The overall power produced by the engine is reduced in the range of 17-19% due to frictional losses. The ability of lubricants to improve fuel economy is critical across the globe. Therefore, research on frictional power loss reduction has gained great attention as a promising direction for fuel economy gasoline engine performance. Reducing total friction losses in vehicles could save the U.S. eco...
