Mainly polycyclic aromatic hydrocarbons, oxygen-containing impurities, containing nitrogen and sulfur compounds in the diesel oil affect its anti-wear lubricating, diesel lubricity depends on the content of anti-wear material, and polycyclic aromatic hydrocarbons, nitrogen-containing compounds have good anti-wear effect, and sulfide does not anti-wear, but the promotion of wear. But the sulfide in diesel mostly heterocyclic form in aromatic hydrocarbons and polycyclic aromatic hydrocarbons, so because of serious environmental pollution of sulfide and advocate the removal of diesel sulfide removal at the same time, also has the lubrication performance and polycyclic aromatic hydrocarbons and other lubrication components. Therefore the use of diesel engine wear and damage with reduction of sulfur content, shorten the service life. To solve the problem of low sulfur diesel lubricity can be approached from two aspects:Analysis the reason of generator pump failure, improved engine design; ‚by adding anti-wear additive solution. Since the project cost improved engine equipment is expensive, and takes a long time, the foreign oil company is adding anti-wear agent to improve diesel fuel lubricity, reduce the loss of equipment. Adding the anti-wear agent to improve the lubrication of diesel oil is the most economic and effective way.
Our current production of new diesel anti-wear agent is a non-acid and noncorrosive ester diesel anti-wear agent. It has good compatibility with other additives. After adding, it will not form colloidal or settlement in the diesel, and not affect other properties(such as low-temperature fluidity, oxidation stability, cetane and anti-static property etc.). At the same time, compared with similar products of domestic manufacturers, it overcomes the disadvantages of the bad anti-wear property and large application amount. This product has a better ratio of performance and price, and adding has no adverse effect to the quality of diesel, performance reached the international advanced level, content in the range of 100-300ppm can have a significant effect.
