First, acid corrosion wear:
The formation of acid is due to the combustion of gasoline and air to form sulfur oxides and nitrogen oxides, which are mixed with water to form sulfuric acid and nitric acid. Sulfuric acid and nitric acid and metal iron and complexes form iron salts and complex salts that wear engine parts.
Solution: This type of wear requires an acid neutralizer to neutralize the acid. The TBN value represents the value of the acid in the neutralizing engine oil. The total value of the alkali is included. The additive for neutralizing the acid is mainly calcium carbonate. The neutralizing agent dispersing detergent of the large alkali particles can be dispersed in the engine oil in a large amount, independently and dispersedly, and dispersed in the engine. Every corner of the cylinder, therefore with a higher efficiency and "acid" ability.
Second, the production of gray smoke:
Most of the formation of gray smoke is caused by incomplete combustion of gasoline and diesel. The particle size of gray smoke is 0.05-1 mm. Most of the gray smoke can pass through the regular filter, but the gray smoke has electric particles like magnets. They attract each other and will condense into pieces. Viscous gray smoke will cause an increase in the viscosity of the oil, which will form dirt and deposits that hinder the oil circuit and the filter.
Solution: Dispersing additives must be added to the lubricant to prevent the ash from condensing into a lump to avoid engine and mechanical life.
Third, engine oil oxidation and aging deterioration:
Combustion of gasoline, diesel and air produces sulfur oxides and nitrogen oxides.
Solution: To control the oxidation of engine oil, it is necessary to add an antioxidant to passivate the catalytic effect of the metal on oxidation to achieve the purpose of extending the oil and protecting the machine.
Fourth, the loss of viscosity:
Loss of viscosity can wear the engine due to the high and low operating temperatures of the engine.
Solution: In order to meet the working requirements when the engine oil is high or low, it is necessary to have a good viscosity index improver. When added to the oil, it can increase the viscosity of the oil and increase the viscosity index of the oil. The low viscosity of the oil at low temperatures ensures that the machine is not subject to wear and has a good oil film at high temperatures to ensure the operation of the machine.
Fifth, the anti-wear properties of engine oil:
The metal surfaces wear when the parts are in operation.
Solution: Adding anti-wear agent will form a chemical reaction film on the metal surface, which can prevent the metal surface from being scratched and welded, thus protecting the engine operation, such as Momo's molybdenum dioxide additive.
Sixth, to prevent corrosion:
When gasoline burns in the engine, it produces water that can corrode the metal, reducing engine life.
Solution: In order to inhibit metal rust, a rust inhibitor is added to the engine oil. The polar gene of the rust inhibitor has a strong adsorption force on the metal surface, forming a tight single or multi-molecular protective layer on the metal surface to prevent corrosion. The medium is in contact with the metal to prevent rust.
7. Foaming and emulsification of engine oil:
The oil will be contaminated by water during use, and the water will emulsify the oil and cause adverse effects on the engine.
Solution: After adding anti-emulsifier, it can change the tension between the oil and water to quickly isolate water and oil. Foaming is caused by the presence of a very small amount of polar substances in the base oil. Foaming affects the pumping of the lubricating oil and destroys the strength and stability of the oil film. Therefore, by adding an anti-foaming agent, it can be adsorbed on the oil film to form an unstable film, thereby achieving the purpose of destroying the foam and protecting the engine.
Eight, gray sand into the engine room:
As the air intake system oil cap venting device detects the harsh working environment of the cover, the sand will enter the engine room. Due to the corrosive nature of silicon oxide, metal wear increases rapidly, and the metal wear rate increases with the increase of contaminants, leading to premature destruction of equipment.
solve:
·Air filter wear - replacement
·The air filter or cover is not fixed - reset
· The ring position is incorrect - if it is flattened or distorted, it can be reset
· Air rubber clip loose - fasten
· Air rubber tube wear or perforation - replacement
·The cover is missing or loose - replacement or fastening
· Intake filter lost or blocked - replacement
· Oil spill - blocking the loophole (if oil leaks, it means there is silicon)
