What is the function of the engine lubrication system?
2 Answers
The functions of the engine lubrication system are: 1. Lubrication: Engine oil forms an oil film between moving parts, reducing friction resistance and power loss, and minimizing component wear. 2. Cooling: The fluidity of the engine oil helps dissipate heat from engine components, preventing overheating and potential damage. The basic components of the engine lubrication system include the oil pump, oil filter, oil cooler, and oil strainer. The system also comprises an oil pressure gauge, temperature gauge, and oil pipelines. An engine is a machine that converts other forms of energy into mechanical energy. It can refer to either the power-generating device or the entire machine including the power unit. Types of engines include internal combustion engines, external combustion engines, gas turbines, and electric motors.
I've been fixing cars myself for many years, and the lubrication system in an engine is like adding a bit of magical lubricant to the machine. Its main function is to reduce friction between various metal parts, such as pistons and bearings. Without oil, these parts would directly rub and collide, easily wearing out and getting damaged. I've personally seen several engines where the oil wasn't changed—when taken apart, they were full of scratches, and repairs were extremely costly. Additionally, the engine heats up significantly when started, and the oil helps dissipate this heat. Otherwise, the high temperatures can cause parts to deform or even burn out, leading to scary situations like smoke coming out during long drives. The lubrication system also cleans out dirt, such as metal fragments and dust, keeping the engine interior clean and rust-free, which makes the car run smoother and more fuel-efficient. I recommend car owners regularly check oil levels and change the oil to prevent it from degrading and losing effectiveness—this can help the car last several more years.
