Panangiyam-ammo ti produkto .:
Polycyclic aromatic hydrocarbons, oxygen impurities, nitrogen impurities and sulfur compounds in diesel oil are the main substances that affect the lubrication of diesel oil itself. The strength of diesel oil lubrication depends on the content of anti-wear substances. Polycyclic aromatic hydrocarbons, nitrogen compounds have a good anti-wear effect, and sulfide not only does not resist wear, but promotes wear.However, most of the sulfur compounds in diesel oil exist in heterocycle form in aromatic hydrocarbons and polycyclic aromatic hydrocarbons. However, because of the serious environmental pollution caused by sulfide, the removal of sulfur compounds in diesel oil is strongly advocated, and the removal of lubricating aromatics and polycyclic aromatic hydrocarbons and other lubricating components are also removed.Therefore, with the reduction of sulfur content, diesel engine appears wear and damage, shorten its service life.There are two ways to solve the problem of lubricity of low sulfur diesel: analyze the failure reason of engine oil pump and improve engine design;It is solved by adding anti-wear additive.Because of the huge cost and long time to improve the equipment of the engine, foreign oil companies mainly add anti-wear Dagiti ahente a mangpasayaat iti lubricity ti lana ti diesel ken mangkissay iti pannakapukaw dagiti alikamen.Ti pananginayon iti antiwear nga ahente tapno mapasayaat ti lubricity ti diesel oil ti kaekonomiaan ken kaepektibuan a pamay-an iti agdama..

In recent years, with the continuous strict of fuel regulations and the introduction of new environmental protection laws and regulations, the requirements for environmental protection are getting higher and higher.Therefore, new requirements have to be put forward for nitrogen and sulfur content, and stricter requirements have to be put forward for cetane number, cold flow performance, aromatics content, 90% or 95% distillate temperature (T90 or T95), density and so on in diesel product indexes.The hydrotreated diesel removes sulfur and aromatics, but it also removes natural components that have anti-wear properties, greatly reducing lubrication and increasing friction between metals.It is estimated that about one third of the energy consumed in friction, and more than two thirds of the parts damaged by wear and tear are scrapped.Therefore, improving lubrication performance to reduce friction, wear ken ti pananglapped ti sintering ket addaan iti dakkel a kaipapanan iti nailian nga ekonomia..
