Abstract

The invention discloses an antifriction energy-saving engine lubricating oil composed of, by weight: 50-60% of hydroisodewaxing type III base oil, 25-30% poly a olefin PAO, and 10-25% of a lubricating oil additive. The lubricating oil additive comprises: 1-2% of an antifriction agent, 2-3% of a detergent dispersant, 1.5-2% of an antioxidant and corrosion agent, 0.3- 0.7% of a depressant, 6-15% of a viscosity index improver, and 0.01% of a defoaming agent. The antifriction agent adopted in the invention is complexed by using molybdenum-dithiocarbamate and molybdenum-dithiophosphoric acid, such that the antifriction effect, wear-resistance, engine mute effect, and antifriction and oil-saving effect are significant. When the lubricating oil is used in large-scale heavy vehicles, under full load and harsh road conditions, the engine system can be better protected, service life can be prolonged, and fuel can be saved. With the lubricating oil, vehicle abrasion under high temperature and high load and abnormal increasing of vehicle fuel consumption under high temperature and high load can be solved. The lubricating oil has good friction characteristics, good mechanical stability, good thermal stability, and excellent oxidation stability.

Description

Technical field [0001] The invention relates to a lubricating oil, in particular to a friction-reducing and energy-saving engine lubricating oil. Background technique [0002] "Lubrication" is a traditional equipment management technology. With the development of modern equipment to large-scale, precise and automated, there are higher requirements for the traditional technology of "lubrication", which is mainly manifested in how to use advanced lubrication technology and deployment methods. , Reduce the abnormal wear of equipment, reduce the consumption of spare parts, reduce energy loss, and ensure the safe operation of equipment. Existing large and heavy-duty vehicles have large operating loads, high summer temperatures and large wear and tear, which have a great impact on the life of the vehicle. Therefore, providing a lubricant to solve the problem of heavy vehicles in high temperature and high load environments can be better It is particularly important that wear prolongs t...
