What are the functions of engine oil in the lubrication system?
2 Answers
Here are several functions of engine oil in the lubrication system: 1. Lubrication: Reduces friction resistance and wear, decreasing engine power consumption. 2. Cleaning: Cleans friction surfaces by carrying away wear debris and other foreign particles. 3. Cooling: Dissipates heat generated by friction, providing a cooling effect. 4. Sealing: Enhances sealing performance, helping to prevent gas or oil leaks. 5. Anti-corrosion: Protects component surfaces to prevent corrosion and rust. 6. Hydraulic function: Lubricating oil can serve as hydraulic oil, such as in hydraulic lifters, performing hydraulic functions. 7. Vibration damping: Absorbs impacts and reduces vibrations, providing a damping effect.
Well, as a veteran driver with over 20 years of experience, I can tell you about the wonderful uses of engine oil. The primary function of engine oil is lubrication—it coats metal parts like pistons and crankshafts with an oil film to reduce friction and wear. I remember when I was young and drove an old, beat-up truck without changing the oil on time—the engine roared like thunder. Later, I learned that engine oil also helps cool things down, circulating to carry away heat from the piston tops, so you don’t have to worry about engine overheating during long summer highway drives. The cleaning effect is also remarkable—fresh oil is bright and clear, but over time, it turns black as it traps dust and metal shavings. Just replace it, and it helps keep the engine internals clean. In terms of sealing, engine oil fills the gaps in piston rings to prevent combustion chamber leaks that can sap power. Rust and corrosion prevention is also crucial—additives protect parts from rust and extend engine life. I advise car owners to regularly check oil levels and color and keep up with maintenance for peace of mind.
