Problems solved by technology

[0002] For a long time, although my country's diesel oil has ex-factory standards, most of them do not meet the standards for sulfur and wax. Therefore, the requirements for engine oil are stricter in terms of base value, oxidation resistance, and cleaning and dispersibility, so as to delay the damage to the engine block caused by fuel oil that does not meet the standards. damage
However, the sulfur and phosphorus contained in the diesel engine to solve the anti-wear will accelerate oxidation during the repeated movement of the cylinder. In addition to losing the anti-wear performance, it will also produce sludge and carbon deposits, which seriously affect the life of diesel oil and the engine.
The traditional sulfur-phosphorous (SP) lubricating oil begins to decompose at 120°C, resulting in a rapid decline in the anti-oxidation performance of the lubricating oil, rapid loss of lubricating function, damage to equipment, and increased wear of cylinders and other equipment, resulting in serious safety hazards Hidden danger
Traditional lead-sulfur (S-Pb) and sulfur-phosphorus (SP) lubricating oils have unstable lubricating effects. The former has poor lubricating performance under high-speed impact load conditions, while the latter is just the opposite

Embodiment 2

[0029] The diesel engine oil formula provided by the present invention, raw materials include three types of hydrogenated oil S6 with a mass percentage of 45.2%, three types of hydrogenated oil S8 with a mass percentage of 32%, and an index improver American Infineum V261 with a mass percentage of 5.65% , 0.56% by mass of pour point depressant V248, 10.56% by mass of diesel oil compounding agent American Infineum D3451, 6% by mass of extreme pressure and antiwear agent T362, and 0.03% by mass of complex anti-wear agent No. 2 antifoaming agent.

Embodiment 3

[0031] The diesel engine oil formula provided by the present invention, raw materials include three types of hydrogenated oil S6 with a mass percentage of 45.2%, three types of hydrogenated oil S8 with a mass percentage of 32%, and an index improver American Infineum V261 with a mass percentage of 5.65% , 0.56% by mass of pour point depressant V248, 15.57% by mass of diesel engine oil compounding agent American Infineum D3451, 1% by mass of extreme pressure and antiwear agent T362, and 0.02% by mass of complex anti-wear agent No. 2 antifoaming agent.

[0032] Among them, in the diesel engine oil formula provided by the present invention, the extreme pressure antiwear agent T362 itself in the raw material can form a layer of deposited film on the surface of the oil cylinder. It melts at 60°C-120°C, and each component in the raw material will form a layer of elastic protective film at this temperature. This elastic protective film has metal adhesion and adheres to the surface of...
