Is 4 Liters of Engine Oil Enough for the Regal?
1 Answers
Adding 4 liters of engine oil is sufficient for the Regal. Here is extended information about the functions of engine oil: 1. Lubrication: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. 2. Auxiliary Cooling: Engine oil has a relatively low specific heat capacity and is located inside the engine, so it does not inherently have a cooling effect. However, during engine operation, the heat energy generated by fuel combustion can be carried back to the oil tank by the engine oil and then dissipated into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water (or antifreeze liquid) outside the engine shell. 3. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation. The flow of the lubricating oil washes away contaminants generated on the working surfaces of the parts. 4. Sealing and Leak Prevention: Engine oil can form a sealing ring between the piston rings and the piston, reducing gas leakage and preventing external pollutants from entering. 5. Rust and Corrosion Prevention: Lubricating oil can adhere to the surfaces of parts, preventing contact with water, air, acidic substances, and harmful gases.
