Engine oil is a very complex oil. Today's high-performance engine lubricants contain a variety of components, such as base oils, the best oil additives, and viscosity modifiers, each of which plays its important role and is balanced to form the final formula.
To ensure that the lubricants perform as required, oil manufacturers must carefully prepare and test each lubricant to meet or exceed specific certification and performance requirements. This article describes the standard components of engine oils, the complexity of their formulations, and the various effects that lubricants must achieve.
Base oil
Let us first discuss base oils. The American Petroleum Institute (API) divides base oils into five categories, each of which has significantly different technical and performance characteristics. Although the base oil is the most significant proportion of heavy vehicle engine oil (usually 60-95% by weight), even the highest quality base oil cannot achieve all-round protection of the engine from high temperatures, Shear force, abrasive particles, chemical dilution, water dilution, and corrosion.
When developing compound additives, formulators must consider the characteristics of the base oils they use, as each base oil has different requirements for oil additives formulations.
Stickiness improver
Viscosity improvers are specially designed polymers used to control the viscosity (thickness) of lubricating oils in specific temperature ranges and working environments. As engine components become more and more sophisticated, advanced polymers not only help the engine operate more efficiently in increasingly harsh environments but also play a key role in improving efficiency, durability, and protection.
A variety of viscosity modifiers have been developed, and the choice of which depends on several related factors, including the operating conditions of the lubricant, the characteristics of the base oil, and oil additives.
Different Oil Additives
Although oil additives are a relatively small component of lubricating oils, they play a significant role in protecting key engine components.
Additives to clean engine
Additives to clean engine-The The engine cleaner additive is used for fuel or oil additives, and its role is to keep engine components clean. In automotive oil formulations, the most commonly used detergents are metal soap salts with sure alkalinity, which can neutralize the acids produced during the combustion process. (keep clean)
Dispersant
The role of dispersant is to suspend pollutants in the oil and prevent the formation of sludge and paint films on engine parts. Dispersants are usually non-metallic ("ashless") substances and are used in conjunction with detergents. (Control of pollutants)
Antioxidants
Antioxidants-Antioxidants are also called oxidation inhibitors. The effect of this low-dose additive is to slow down the oxidation rate of the lubricant. (Slows down oxidation)
Anti-wear additives
The role of anti-wear additives is to form a tough film on highly loaded parts to block contact between metal surfaces. (Reduces engine wear)
Friction modifier additive can adhere to the surface of the region and reduce friction and wear when slight conflict occurs. The amount of resistance depends on the smoothness of the contact surface and the pressure between the two surfaces. (Reduces engine wear)
Anti-foam additives
The role of the antifoaming agent is to inhibit the formation of foam in the lubricating oil. Foam can cause cavitation on the pump or reduce lubricant flow. (Reduce cavitation)
Corrosion inhibitor
The role of corrosion inhibitors is to prevent metal surfaces from chemically reacting with water or other contaminants. (Control of corrosion and acids)
Pour point depressant
Pour point depressants can reduce the pour point of a petroleum product, that is, fluidity at low temperature and low shear rate. (Controlling viscosity)
All of the above oil additives must be balanced for the lubricating oil to exert specific effects. Trunnano's formulation experts have professional and sophisticated formulation technology to ensure that all additives, base oils, and vicious agents do not conflict with each other to achieve the efficacy of lubricants jointly.
If the content of one oil additive is high, it may inhibit other oil additives and viscosity improvers from functioning. For example, if the antifoam content is too low, the lubricating oil will foam, cavitating the engine and causing damage. Similarly, if the wrong type of oil cleaner additive is used, the acid in the lubricant cannot be neutralized. Then the dispersant cannot effectively prevent the formation of soot and settle on the engine parts.
Therefore, all oil additives must be blended in precise proportions to work correctly. And Trunnano's expertise in chemistry can do just that. Trunnano's formulation experts know how to formulate professional compound additives to meet a variety of requirements from durability to protection, to achieve excellent fuel economy and efficiency.
