What Are the Six Major Functions of Engine Oil?
1 Answers
The six major functions of engine oil are as follows: Lubrication and Friction Reduction: Forms an oil film on the surfaces of two sliding components to prevent friction during operation, ensuring smooth movement of the parts. Cleaning and Dispersion: High-quality engine oil can flush away dirt from component surfaces by flowing and adsorb tiny metal fragments inside the engine, which are then scraped into the oil pan by the piston oil ring. Cooling and Temperature Reduction: When the engine operates, it generates high temperatures. As the oil reaches the operating parts, it absorbs heat and carries it away, aiding in the cooling of the components. Sealing and Leak Prevention: Refers to the formation of a sealing ring via an oil film between the piston rings and pistons, preventing combustion exhaust gases from entering the crankcase. Rust and Corrosion Prevention: High-quality engine oil can adhere to component surfaces, preventing contact with air, acidic substances, and harmful gases, thus protecting the engine from corrosion by the atmosphere and water. Shock Absorption and Cushioning: When the pressure in the engine cylinder increases suddenly, the load on the pistons, piston rings, connecting rods, and crankshaft bearings becomes significant. This load is transmitted and lubricated through the bearings, cushioning the impact load.
