Abstract

The invention provides lubricating oil for a methanol fuel engine, which comprises the following components in percentage by weight: metal detergent 2.2-5.2, ashless dispersant 3.5-6.8, antioxidant and anticorrosion agent 0.5-1.6, high-temperature antioxidant 0.3-0.8, viscosity index improver 6-11, oiliness solvent 2.8-6, anti-foaming agent 120ppm, metal anti-rust agent 0.3-0.7, base oil 62.7-83, demulsifying agent 0.1-0.3, metal extreme pressure anti-wear agent 1.0-4 and pour point depressant 0.3-0.9. The lubricating oil of the invention has functions of preventing wear and rust of the engine, can prevent the active ingredients thereof from being extracted and emulsified by methanol and is particularly suitable for engines using M85 or M100 methanol gasoline as a fuel.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a lubricating oil for a methanol fuel engine and a preparation method thereof. technical background [0002] Petroleum, as a non-renewable resource, has less and less reserves, and with the development of the world economy, the application of petroleum derivatives is becoming more and more extensive. In this way, the development of alternative products for petroleum resources has become a major issue in the world's scientific and technological circles. As a coal conversion product, methanol can temporarily reduce the application ratio of petroleum resources. At present, with the increasing awareness of environmental protection around the world, the control of air quality and vehicle exhaust emissions has become an important part of environmental protection. However, the level of pollutants emitted by engines using methanol as fuel is very low, so methanol is used as a fuel for engines in va...
