What is the Ashless dispersants?

2024-08-28

Ashless Dispersant is a type of substance that adjusts the performance of internal combustion engine oil. When used in combination with Oil Additive, it can more effectively prevent deposits formed by oxidation products during the use of internal combustion engine oil.

The chemical structure of ashless dispersant is composed of lipophilic groups, polar groups and connecting parts. Such a chemical structure can easily form micelles in lubricating oil, ensuring that it has a strong solubilizing effect on liquid initial oxidation products, and has a good peptizing and dispersing effect on solid particles such as carbon deposits and soot, effectively ensuring the low-temperature dispersion performance of internal combustion engine oil, and especially effectively solving the low-temperature sludge problem of gasoline engine oil. When gasoline engine oil with dispersant is changed after running for a long time, the sludge in the crankcase is reduced, and the dispersing and solubilizing effect on soot and lubricating oil oxidation products generated by high-temperature oxidation is also improved. In particular, it has a synergistic effect when combined with metal detergents, which not only improves the quality of the lubricating oil, but also reduces the amount of Industrial Oil Additive added.

What is the role of Ashless dispersants?

Solubilization: Some oxidation products are polymerized and mixed with condensed water to form engine sludge, which increases engine carbon deposits and adheres to the fuel tank to prevent the oil pump from sucking in, thereby clogging the filter. Succinimide dispersants can form micelles with carbon deposits and sludge that are insoluble in oil, and complex with them to form oil-soluble liquids and disperse in the oil. Dispersants have the best solubilization effect, which is about 10 times higher than detergents.

Ashless Dispersing effect: The oil-soluble groups provided by dispersants are larger than those of detergents, which can effectively prevent carbon deposits and colloids from aggregating with each other, and can effectively disperse 0~100nm samples in the oil.
