What are the functions of an engine lubrication system?
1 Answers
The functions of an engine lubrication system include: 1. Lubrication: Engine oil forms an oil film between moving parts to reduce friction resistance, power loss, and component wear; 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, dust absorbed from the atmosphere, and some solid substances produced by fuel combustion, preventing the formation of abrasives between parts that could accelerate 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. Rust prevention: The lubricating oil film adheres to metal surfaces, isolating air and water, thereby preventing rust and corrosion.
