Problems solved by technology

[0004] Although most of the old cars have not reached the national motor vehicle compulsory scrapping period in terms of service life, due to the long-term use of old cars, the wear between the cylinder and the cylinder liner is serious, and the sealing performance of the engine is not good, resulting in incomplete fuel combustion. , so that the exhaust emission cannot meet the national standard, and it needs to be scrapped compulsorily

Embodiment 1

[0042] Add one-half of the prepared fully synthetic base oil into the blending kettle, raise the temperature to 85°C±5°C, add viscosity index improver (7%), polymethacrylate pour point depressant (0.5%) and keep stirring 1h. Add the remaining base oil, keep the temperature at 60°C, add the engine oil compounding agent (8%), continue stirring for 30 minutes, add anti-wear agent (0.8%) and defoamer (0.003%), continue stirring for 30 minutes, cool to get the finished product .

Embodiment 2

[0044] Add one-half of the prepared fully synthetic base oil into the blending kettle, raise the temperature to 85°C±5°C, add viscosity index improver (6.5%), polymethacrylate pour point depressant (0.3%) and keep stirring 1h. Add the remaining base oil, keep the temperature at 60°C, add the engine oil compounding agent (8%), continue stirring for 30 minutes, add anti-wear agent (0.5%) and defoamer (0.003%), continue stirring for 30 minutes, cool to get the finished product .

Abstract

The invention discloses gasoline engine oil with a repairing function and an exhaust reducing function for an old vehicle. The gasoline engine oil is prepared from, by weight, 7.5%-12.5% of gasoline engine oil compound agent, 0.2%-0.5% of pour point depressant, 5%-12% of viscosity index improver, 0.3%-1% of antiwear agent, 0.002%-0.005% of anti-foaming agent and the balance base oil. According to the gasoline engine oil with the repairing function and the exhaust reducing function for the old vehicle, the base oil adopts high-viscosity polyester, and due to the fact that ester oil contains ester groups and has high polarity, physical bonds can be formed on the metal surface; therefore, ester molecules are easily adsorbed on the friction surface to form an oil film which serves as an effective lubricating agent, the oil film formed by high-viscosity polyester is larger in thickness and can effectively seal a gap, produced due to wear, of an engine, improve the sealing property of the engine and repair the engine, and therefore fuel is completely burnt.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a gasoline engine oil which has the function of repairing old cars and reduces exhaust gas Background technique [0002] In recent years, with the rapid development of our country's economy, the number of motor vehicles in our country has grown rapidly at an average rate of more than 11% per year, becoming the largest country in the world in terms of car sales. The rapid increase in the number of motor vehicles makes motor vehicles the main energy consumers. Due to fuel combustion, incomplete combustion, volatilization and other reasons, a large amount of exhaust gas is emitted to the atmosphere, including carbon monoxide (CO), carbon dioxide (CO 2 ), hydrocarbons (HC), nitrogen oxides (NO X ), particulate matter (PM) and sulfide (SO X )Wait. The latest data shows that Beijing and Shanghai air pollution motor vehicle exhaust contribution to PM2.5 reached 31.1% and 25.8...
