Problems solved by technology

However, under high-speed and high-torque conditions, due to the high load of the engine, the oil temperature will be high during long-term operation, and under high-speed operation conditions, the shear rate of the engine oil is high, greater than 10 8 / s, the high temperature and high shear rate of conventional engine oil is generally 150°C, and the shear rate is 10 6 / s, and the bench test and driving test of general engine oil are not enough to simulate this state
The viscosity of lubricating oil becomes smaller at high temperature and high shear rate, which easily leads to insufficient oil film thickness, and in the critical state, the function of some additives does not meet the requirements, resulting in increased wear of friction pairs
In the case of ultra-high torque and extremely high shear rate, the wear of the friction pair still needs to be further improved

Abstract

The invention discloses double anti-wear automobile lubricating oil. The lubricating oil comprises, by mass, A), 35-94 parts of a low-viscosity base oil having a high viscosity index, B), 2-15 parts of a engine oil composite agent, C), 0.01-3 parts of a organic molybdenum mixture, D), 0.5-5 parts of a saturated and high-viscosity complex lipid, E), 0.5-10 parts of a diester, F), 0.5-10 parts of ahigh-viscosity polyolefin, G), less than or equal to 2 parts of a alcohol blocked phenolic ester having high molecular weight and H) 2-10 parts of a viscosity index improver with high shearing performance. The double anti-wear automobile lubricating oil provided by the present invention is used for engines of the automobiles, such that starting wear of the engine is substantially improved, the wear of the engine in a operation condition of high rotary speed and high torsional moment is reduced. In addition, according to the present invention, a starting noise level is reduced by 12%; an outside noise level is reduced by 6.8% and an interior noise level is reduced by 8.4% during a high-speed operation; a oil change period of the engine oil is prolonged more than one time.

Description

technical field [0001] The invention relates to a lubricant for vehicles, in particular to an anti-wear lubricant for vehicles. Background technique [0002] The general requirement of modern engines is to generate more power under the premise of small size and light weight, as well as more and more stringent energy-saving and environmental protection requirements, resulting in a substantial increase in engine power per liter, while the piston and connecting rod are shortened. The loads on piston rings and cylinder walls, valve lifters and cams, crankshafts and bearing bushes, etc., which have the most severe working conditions, are greatly increased. Conventional lubricating oils are constantly improving in quality to meet the requirements of comprehensive engine lubrication, sludge dispersion and anti-corrosion and anti-wear. For example, the invention patent publication number is CN101838575A "an energy-saving engine oil additive composition", etc., all provide engine oi...
