Problems solved by technology

[0002] The working principle of the diesel engine is the compression ignition type, the engine speed is high, the specific power is high, the oil temperature is high, and the requirements for anti-friction and anti-wear performance are very high. The soot generated by the engine will form deposits in the piston ring area; the sulfur content of diesel The amount of sulfur is 10 times that of gasoline, and the sulfur content of residual oil diesel engine fuel is more than 100 times that of gasoline. Accelerate the formation of deposits in lubricating oil. The temperature in the cylinder area of ​​a diesel engine is much higher than that of a gasoline engine. The temperature in the first ring zone has reached 250-300 ° C. The above-mentioned factors and their interactions will cause various problems in the diesel engine. A variety of problems in use, such as snap rings caused by deposits in the piston ring area, which will cause engine failure or power loss, due to the accumulation of acid products and oil oxidation and aging, it will cause serious wear of piston rings and cylinder liners, and reduce fuel consumption. Increase and shorten the service life of diesel engines. In recent years, the development of metal wear self-repair technology provides an extremely effective method for the effective maintenance and maintenance of diesel engines during operation.

Embodiment 1

[0007] A formula of anti-rust lubricating oil. The raw materials in the formula are composed by weight percentage: 5% compound agent, 1% antioxidant, 1% viscosity index improver, 5% tackifier, 3% pour point depressant, Anti-foaming agent 2%, functional enhancer 1%, anti-corrosion agent benzotriazole 11%, 2-mercaptobenzothiazole 5%, composite ashless dispersant 3%, nano-ion formula 3%, sodium citrate 1%, Potassium dihydrogen phosphate 5%, Tween 1%, polymethacrylate 4%, glyceryl acrylate 2%. At this time, the anti-rust lubricating oil has a mild and refreshing effect, but the makeup is not durable.

Embodiment 2

[0009] A formula for anti-rust lubricating oil, the raw materials in the formula are composed by weight percentage: 15% compound agent, 5% antioxidant, 10% viscosity index improver, 15% tackifier, 9% pour point depressant, Anti-foaming agent 3%, functional enhancer 5%, anti-corrosion agent benzotriazole 19%, 2-mercaptobenzothiazole 7%, composite ashless dispersant 5%, nano-ion formula 5%, sodium citrate 5%, Potassium dihydrogen phosphate 10%, Tween 1.5%, polymethacrylate 5%, glyceryl acrylate 4%. At this time, the anti-rust lubricating oil has a long-lasting effect on makeup, but it is not mild and refreshing enough.

Embodiment 3

[0011] A formula of anti-rust lubricating oil. The raw materials in the formula are composed by weight percentage: 10% of compound agent, 3% of antioxidant, 6% of viscosity index improver, 10% of tackifier, 6% of pour point depressant, Anti-foaming agent 2.3%, functional enhancer 1.5%, anti-corrosion agent benzotriazole 11.9%, 2-mercaptobenzothiazole 5.7%, composite ashless dispersant 3.5%, nano-ion formula 3.5%, sodium citrate 1.5%, Potassium dihydrogen phosphate 8%, Tween 1.28%, polymethacrylate 4.5%, glyceryl acrylate 2.4%, at this time, the anti-rust lubricating oil has a mild, refreshing, long-lasting effect on makeup.
