Problems solved by technology

For example, the chlorine-containing extreme pressure antiwear agent is due to the thermal decomposition of carbon-chlorine chain breaks, and the chlorine released from the decomposition reacts with the metal to form a metal chloride covering film. It is corrosive, and metal chlorides such as ferric chloride will fail at a low melting point of 350°C, so their use is limited
Another example is that phosphorus-containing extreme-pressure anti-wear agents form organic and inorganic phosphate films with certain buffer properties at local high temperatures caused by frictional heat; sulfur-containing extreme-pressure anti-wear agents adsorb on metal surfaces to form metal chloride covering films, Although the use of these organic compound films can improve the extreme pressure resistance of lubricating oil, it has great limitations. The service life of these internal combustion engine oils currently on the market is generally 5000-7000 kilometers, and the consumption of lubricating oil is still large. It not only increases the operating cost, but also emits a lot of harmful substances. In particular, because of its poor anti-friction and wear performance, the parts of the internal combustion engine are worn out, the power is reduced, the life is shortened, the noise is large, and the consumption of lubricating oil and fuel is large, which is harmful emissions are also high, polluting the environment

Description

technical field [0001] The invention relates to a lubricating oil for an internal combustion engine, in particular to a nano lubricating oil for an internal combustion engine and a manufacturing method thereof. Background technique [0002] Lubricating oil for internal combustion engines is mainly used in the motor vehicle industry. When in use, the lubricating oil is added to the fuel tank, and is transported by the oil pump to the cylinder, crankshaft, piston connecting rod, intake valve, exhaust valve, etc. of the internal combustion engine through the pipeline and oil circuit. components, and then flow back to the tank for recycling. Since lubricating oil is added between various friction contact surfaces where relative motion occurs, a lubricating film is formed between the two friction surfaces, and the dry friction becomes the friction between lubricating oil molecules, so as to reduce the friction of moving parts, reduce wear and prolong machine life. The purpose of...
