What are the basic components of an engine lubrication system?

The basic components of an engine lubrication system include the oil pump, oil filter, oil cooler, and oil strainer. The lubrication system also consists of components such as the oil pressure gauge, temperature gauge, and oil pipelines. Due to the varying working conditions of engine transmission parts, different lubrication methods are employed for transmission parts with different loads and relative motion speeds. The function of the lubrication system is to continuously deliver an adequate amount of clean oil at an appropriate temperature to the friction surfaces of all transmission parts during engine operation. It forms an oil film between the friction surfaces to achieve liquid friction, thereby reducing frictional resistance, lowering power consumption, and minimizing component wear. This enhances the engine's operational reliability and durability.
I recently started teaching myself car maintenance, and understanding the engine lubrication system is like understanding the lifeline of an engine. The basic components include the oil pan, which acts like a storage tank at the bottom; the oil pump is responsible for sucking oil from the oil pan and delivering it to various parts through pipelines; the oil filter removes impurities to prevent debris from entering the engine; the main oil gallery consists of those hidden channels that allow oil to flow to bearings and pistons; and there's also the pressure valve that controls oil pressure to avoid damage from excessive pressure. I think the most critical part is the filter because I neglected it last time, leading to dirty oil and engine overheating. Regularly checking these parts can extend the engine's lifespan, so I spend some time each week checking the oil level to ensure everything runs smoothly.
