Problems solved by technology

[0003] However, due to the high oxygen content of methanol, it is easily miscible with water, and the high-temperature oxidation product is formic acid, which is highly corrosive. When it is used as an internal combustion engine fuel, it is easy to generate sludge, coking, emulsification, etc. Corrosion of engine-related components, resulting in reduced horsepower

Embodiment 1

[0036] A kind of lubricating oil, used raw material and weight fraction thereof are as follows:

[0037]

[0038] The production method of this embodiment is: Step 1: Add 20 parts of hydrogenated base oil 250N, 15 parts of paraffin-based neutral oil 500SN, and 12 parts of residual distillate oil 150BS into the material tank according to the parts by weight, and stir and mix under normal temperature and pressure for 20 minute;

[0039] Step 2: Add 5 parts of detergent, 5 parts of dispersant and 5 parts of compounding agent in parts by weight, and stir and mix for 20 minutes at normal temperature and pressure;

[0040] Step 3: Add 5 parts of viscosity improver and 3 parts of viscosity index improver according to parts by weight, stir and mix for 30 minutes at normal temperature and pressure;

[0041] Step 4: Add 10 parts of extreme pressure anti-wear agent, 3 parts of anti-emulsifier, 2 parts of pour point depressant, 5 parts of anti-foaming agent, 3 parts of anti-rust agent...

Embodiment 2

[0044] The difference from Example 1 is that

[0045]

[0046] The production method of present embodiment is identical with embodiment 1

[0047] It can be known through experiments that the present invention has good lubricating and anti-wear effects, reduces friction and wear, improves mechanical properties, possesses the required features of the above methanol gasoline engine, ensures the normal operation of the methanol gasoline engine, lower friction and wear and relatively Long service life. The invention does not use compounds containing chlorine, sulfur and phosphorus, and meets the standard requirements of environment-friendly and green oil treatment technology.

Abstract

The invention discloses a green lubricating oil compound additive for a methanol fuel internal combustion engine. The green lubricating oil compound additive comprises the components in parts by weight: 3-8 parts of a clearing agent, 3-8 parts of a dispersing agent, 1-7 parts of an antioxidant, 6-14 parts of an extreme pressure anti-wear agent, and 3-8 parts of a compounding agent. The invention also discloses lubricating oil adopting the compound additive and a production method thereof. The lubricating oil adopting the compound additive has the advantages of quite good alkali value keeping ability, corrosion inhibition ability and anti-wear performance.

Description

technical field [0001] The invention relates to the field of lubricating oil additives, in particular to a green lubricating oil composite additive for methanol fuel internal combustion engines, a lubricating oil using the composite additive and a production method thereof. Background technique [0002] At present, environmental pollution and energy shortage are increasing day by day, which promotes the research and application of new fuels. As a new type of vehicle fuel, formaldehyde has been further promoted and applied as a clean energy source for vehicles. [0003] However, due to the high oxygen content of methanol, it is easily miscible with water, and the high-temperature oxidation product is formic acid, which is highly corrosive. When it is used as an internal combustion engine fuel, it is easy to generate sludge, coking, emulsification, etc. Corrosion of engine-related components can result in reduced horsepower. [0004] Therefore, the inventor made further rese...
