What are the functions of the lubrication system?

[JuniperAnn]

The functions of the lubrication system include the following points: 1. Lubricate the surfaces of moving parts to reduce friction resistance and wear, thereby decreasing engine power consumption; 2. Continuously circulate oil within the lubrication system to clean friction surfaces and carry away debris and foreign particles; 3. Continuously circulate oil within the lubrication system to carry away heat generated by friction, serving a cooling function; 4. Form an oil film between moving parts to improve sealing and prevent gas or oil leakage; 5. Create an oil film on part surfaces to protect them from corrosion and rust; 6. Lubricating oil can also be used as hydraulic oil, serving a hydraulic function; 7. Form an oil film on the surfaces of moving parts to absorb impacts and reduce vibrations, providing shock absorption and cushioning effects.

The lubrication system is like the guardian angel of the engine, and I can share some real insights. Back when I first started driving, the mechanic explained in detail during maintenance that its primary role is to reduce friction between internal components—like the crankshaft and pistons. When these metal parts rub against each other, they generate heat and wear, but applying engine oil makes them glide as smoothly as ice skating. It also cools the engine; at high speeds, component temperatures soar, and the lubricating oil film carries away heat to prevent overheating and engine failure. The cleaning function shouldn’t be overlooked either—engine oil flushes metal debris and carbon deposits into the filter, preventing clogs in the pipelines. Another clever feature is sealing the combustion chamber, helping piston rings fit tightly to boost fuel efficiency and reduce leaks. Rust and corrosion prevention is also crucial, as the oil forms a protective layer to shield parts from moisture and erosion. Regular oil changes keep the car lively and extend its lifespan, whereas neglecting them could lead to engine seizure, costly repairs, or even total failure.

As a newbie who hasn't been driving for long, I once asked a mechanic what the lubrication system does, and he explained it quite clearly. Mainly, it coats the engine internals with lubricating oil to reduce friction-generated heat between parts and prevent metal wear and tear; secondly, cooling is crucial—when the engine runs at high speeds, temperatures soar, and the circulating oil helps cool it down to prevent overheating and protect components; then there's the cleaning function, acting like a magnet to attract dust and metal particles, filtering out dirt through the oil filter to keep the internals clean; it also helps seal the cylinders, preventing gas leaks that could lead to power loss; and it prevents rust by isolating parts from air and moisture, extending their lifespan. I've noticed that changing the oil on time keeps the car running quietly and powerfully, while neglecting it leads to louder noises and increased fuel consumption.

From a mechanical perspective, I can share the core functions of the lubrication system. Simply put, it reduces friction to protect critical engine components like pistons and connecting rods, where engine oil forms a protective film for smooth movement and wear prevention; cooling components is another key function, especially in high-temperature areas like the combustion chamber, where oil circulation dissipates heat to prevent overheating and deformation; the cleaning mechanism removes impurities and deposits to maintain internal cleanliness; the sealing function assists piston rings in improving efficiency and reducing gas leakage; anti-corrosion protection prevents metal from rusting and corrosion. Proper maintenance can optimize fuel economy and extend engine life while reducing failures.
