Meihua Yi teaches you how to make the oil have high thermal oxidation
Why should lubricating oil oil have good thermal oxidation stability: 1. Because the engine is at a high temperature, the hydrocarbons of the lubricating oil itself are oxidized with air and NO1, NO2 and SO2 to form alcohols, aldehydes, ketones and acid oxygenates. 2. The engine is not well cooled by high temperature, the lubricating oil is volatile, and the consumption of lubricating oil is increased. 3. The working condition of the cylinder piston is bad. The oil film is reciprocated under the high temperature surface. The high mechanical load is uneven and the high shear rate is high. The pressure on the bearing side is very large, and the oil film is destroyed and oxidized. 4. The oxidation process of lubricating oil is very intense under high temperature conditions. In the thin layer lubricating oil on the surface of the part, part of the light fraction is evaporated, and the other part is deeply oxidized under metal catalysis. Finally, polycondensate is formed and deposited on the surface of the part to form a paint film. . 5. Although the oil temperature in the crankcase is lower, due to the strong agitation and splashing of the lubrication, the contact surface with oxygen is very large, and the oxidation is quite intense, so that the soluble and insoluble matter in the oil is increased. 6. Carbide deposited in the piston tank and adsorbing gas, further coking, forming a paint film, the paint film has a greater hazard, and the cylinder wear is intensified. 7. Especially for modern high-performance engines, the heat load is very high. If there is a supercharged diesel engine, it is necessary to spray lubricating oil into the piston inner cavity to lower its temperature, which puts higher requirements on the oxidation stability of the lubricating oil. In summary, engine oils must have good thermal oxidation stability. We can use the internal combustion engine oil oxidation stability tester MHY-13990 to determine the oxidation stability of the internal combustion engine oil. cat toys interactive,cat toys wand,cat toys balls,cat teething toys AUTRENDS INTERNATIONAL LIMITED , https://www.petspetscare.com
