What is the function of engine oil in an engine?
3 Answers
Engine oil serves the following functions in an engine: 1. Reduces friction and high temperatures; 2. Cools and lowers temperature; 3. Cleans and purifies; 4. Dampens vibrations and cushions impacts; 5. Prevents rust and corrosion. The method for changing engine oil is: 1. Lift the vehicle with a jack, locate and unscrew the drain plug to release the oil; 2. After removing the oil filter, place a container beneath it; 3. Replace with a new oil filter and add new oil. Engine maintenance methods include: 1. Regularly change the engine oil and oil filter; 2. Use lubricants of appropriate quality grades; 3. Periodically clean the radiator; 4. Maintain the three filters; 5. Keep the crankcase ventilated; 6. Regularly clean the crankcase; 7. Periodically clean the fuel system.
Engine oil plays a crucial role in the engine, as I've deeply understood from over a decade of driving experience. It lubricates various metal components like pistons and crankshafts, reducing friction and preventing wear. Otherwise, the engine would squeak and be prone to damage when running. When it's hot, the oil helps dissipate heat; if the engine temperature can't drop, parts may get damaged. In terms of cleaning, the oil carries away dust and impurities, preventing engine clogging. Its sealing function is also critical, ensuring no gas leaks from the combustion chamber. It provides anti-rust protection to keep metals from corroding. Once, I neglected an oil change, and after the oil deteriorated, the engine became noisy and started burning oil, costing me a lot in repairs. Remember, regular oil changes are essential maintenance—don't follow my bad habits. A well-maintained car runs smoothly and gives peace of mind.
Just starting to learn about cars, the role of engine oil amazed me. It ensures smooth operation of internal engine parts, reducing friction and wear. In terms of cooling, when the engine gets hot, the flowing oil helps dissipate heat, preventing overheating damage. Its cleaning function removes carbon deposits and metal debris, keeping the engine clean. It also seals piston rings to reduce gas leakage. The anti-rust protection extends the lifespan of components. I found that changing the oil on time not only enhances performance but also saves fuel due to reduced friction and higher efficiency. Neglecting oil changes can shorten engine life and lead to expensive repairs. I keep a small notebook to track oil change dates, avoiding forgetfulness and trouble. Developing good habits ensures the car lasts longer.
