Problems solved by technology

However, ZDDP is the main source of phosphorus in engine oil. Excessive phosphorus content will cause the active substances in the three-way catalytic converter of the automobile exhaust control device to be poisoned and fail, and the exhaust gas purification function will be lost. Therefore, the usage of ZDDP must be reduced.

Embodiment approach 1

[0033] According to the ratio by weight, 88 parts of synthetic base oil (PAO8:PriEco 3004=5:2) were put into the blending kettle, and under stirring at 65°C, 10.45 parts of T80, 5.4 parts of SV260, and composite antioxidant (Ethanox 4702: LZL205 = 3: 1) 2.0 parts, high alkali value calcium salicylate 1.0 parts, T157 3.0 parts, stir evenly, add 0.15 parts of nano-copper friction modifier, keep the original temperature, stir evenly, let it settle 1 hour, that is, the finished product.

Embodiment approach 2

[0035] According to the proportion by weight, 90 parts of synthetic base oil (PAO9:PriEco 3009=3:2) were dropped into the blending kettle, and under stirring at 70°C, 0.3 parts of T814, 5.5 parts of SV261, composite antioxidant (Ethanox 4710:LZL205=4:1) 1.5 parts, high alkali value sulfurized alkylphenate calcium 0.9 parts, T161A 1.5 parts, stir evenly, add 0.3 parts of nano-molybdenum friction modifier, keep the original temperature and stir evenly, let it settle for 1.5 hours , the finished product is obtained.

Embodiment approach 3

[0037] According to the proportioning by weight, 86 parts of synthetic base oil (PAO7:PriEco 3000=8:3) were dropped into the blending kettle, and under stirring at 60°C, 0.58 parts of T814, 6.4 parts of SV277, composite antioxidant (Ethanox 4716:LZL205=5:1) 2.4 parts, 1.3 parts of high alkali value sulfurized alkylphenate calcium, 3.1 parts of T161A, stir evenly, add 0.22 parts of nano-molybdenum friction modifier, keep the original temperature and stir evenly, let it settle for 2 hours , the finished product is obtained.

Abstract

The invention discloses energy-efficient long-life gasoline engine oil prepared from the following components: synthetic base oil, a composite antioxygen, a metal cleaning agent, an ashless dispersant, a nano-level friction improver, a viscosity improver and a pour point reducer. The gasoline engine oil provided by the invention has the following advantages: requirements of API SM, ILSAC GF-4 and SAEJ300 are met and the service life is long; the complete synthetic base oil features low pour point, high viscosity index, good economy of fuel, degradability and reduced harm to the ecological environment; the phenol type antioxygen is combined with ZDDP, the anti-oxygen and antifriction properties are good and the catalyst poisoning in a tail gas processing unit is prevented; the acid neutralization capacity is good, the cleaning dispersibility is good and the oil sludge and carbon deposit are prevented from being generated; and the nano-level friction improver is added, the frictional factor is low, and the oil film features high carrying capacity and can automatically repair abraded surface and lengthen the service life of the engine.

Description

technical field [0001] The invention relates to an energy-saving long-life gasoline engine oil, in particular to a fully synthetic gasoline engine oil with good fuel economy, long oil change period, little environmental pollution, and effective reduction of engine friction loss, which belongs to vehicle engine lubricating oil Research areas. technical background [0002] With the rapid development of automobiles, people's pursuit of vehicle speed and car maintenance requirements are getting higher and higher, and the competition in the automotive lubricant market is also intensifying. Energy saving, environmental protection, emission reduction, and long life will become the new development of a new generation of automotive lubricants. Therefore, synthetic lubricating oil will be used more for the lubrication and protection of engine oil. Compared with mineral oil, synthetic oil has excellent low-temperature pumpability and fluidity, and is more resistant to high-temperature...
