What are the functions of the lubrication system?

[McJoy]

The functions of the lubrication system include: 1. Lubrication: Engine oil forms an oil film between moving parts, reducing friction resistance and power loss; 2. Cooling: The fluidity of engine oil carries away some of the heat from engine components, preventing overheating and damage; 3. Cleaning: Circulating engine oil removes metal particles generated during engine operation, preventing the formation of abrasives between parts that could increase wear; 4. Sealing: The viscosity of engine oil allows it to adhere to the surfaces of moving parts, improving sealing effectiveness and reducing gas leakage; 5. Anti-rust: The lubricating oil film adheres to metal surfaces, separating air and water, thereby providing anti-rust and anti-corrosion effects.

The primary function of the lubrication system is to ensure smooth operation of internal engine components. Let me explain: It reduces friction between metal parts, preventing excessive wear and extending engine life. Specifically, reduced friction leads to lower fuel consumption and more stable power output. It also has a cooling function – when the engine runs at high temperatures, the oil flowing over component surfaces carries away heat to prevent overheating damage. Cleaning is equally important, as the oil absorbs and removes metal debris, carbon deposits, and other impurities to maintain internal cleanliness. The sealing function is particularly critical for pistons and cylinders, where oil forms a protective film to prevent gas leakage and efficiency loss. Additionally, rust and corrosion prevention fall under the lubrication system's responsibilities, with oil additives protecting metal surfaces from oxidation. Finally, it reduces noise and vibration for a quieter, more comfortable driving experience. In summary, the lubrication system is the soul of an engine – neglecting it may cause premature aging, expensive repairs, or even breakdowns, making regular oil changes an essential maintenance step.

In my daily driving, the role of the lubrication system is simply irreplaceable! It's like putting a slippery protective layer on the engine, significantly reducing part friction and making the car run smoother and quieter. Especially during long-distance driving, when the engine works for extended periods, the engine oil helps dissipate heat, preventing overheating issues that could lead to stalling. The point about cleaning internal impurities is also worth emphasizing—engine oil collects dirt, preventing internal blockages. The sealing function is super important for maintaining engine efficiency; engine oil helps piston rings fit tightly, improving compression and power. In terms of rust prevention, it protects metal from corrosion, extending service life. Additionally, sufficient lubrication can reduce noise, making the cabin atmosphere quieter at high speeds. From an economic perspective, proper lubrication saves fuel and reduces maintenance costs. In short, the lubrication system makes the car as reliable as an old friend. Without proper maintenance, wear accelerates quickly, so I always choose the right specification when changing the oil.

The lubrication system serves many purposes, but simply put, it prevents the engine from seizing, rusting, or making noise. It reduces friction between small parts, and with less friction, parts wear out more slowly, allowing the car to last longer. Engine oil also helps with cooling—if the engine gets too hot, it can fail, and the oil's cooling effect is quite effective. It also has a cleaning function, sweeping away dust and debris to maintain cleanliness. The sealing function benefits the car's airtightness; good sealing when the piston moves ensures sufficient power. As for rust prevention, oil coating on metal makes it less prone to rust. Noise reduction is also practical—good lubrication means fewer squeaks and rattles while driving. Overall, the lubrication system ensures the car runs smoothly, so don't neglect oil change intervals.
