What are the components of a lubrication system?

Lubrication system consists of three major components: oil supply device, filtration device, and instrumentation & signaling device. Oil supply device: Includes oil pump, oil passages, oil pipes, pressure relief valve, etc., which enables oil to circulate in the system at a certain pressure and flow rate. Filtration device: Comprises oil strainer, coarse filter, fine filter, bypass valve (clogging indicator), capable of removing various impurities from the oil. Instrumentation & signaling device: Includes clogging indicator, pressure sensor, oil pressure alarm, warning light and pressure gauge, etc., allowing the driver to monitor the working status of the lubrication system at any time. Working principle of lubrication system: The main oil pump draws lubricating oil from the engine oil pan, then flows the oil into the oil cooler. The cooled oil passes through the oil filter and enters the main oil pipe at the lower part of the engine block, reaching various lubrication points under pressure. Function of lubrication system: During engine operation, it continuously delivers sufficient quantity of clean oil at appropriate temperature to all transmission component friction surfaces, forming an oil film between surfaces to achieve liquid friction. This reduces frictional resistance, lowers power consumption, decreases component wear, thereby improving engine reliability and durability.
I'm very familiar with the lubrication system because it's the cornerstone that ensures the engine runs smoothly. Simply put, it mainly consists of several key components: the engine oil is the core, stored in the oil pan like a reservoir; the oil pump is responsible for sucking and pumping the oil, pushing it to every corner; the oil filter removes impurities to prevent dirt from damaging the engine; the oil passages act like a network of pipes, connecting moving parts such as the crankshaft and camshaft; and there's the oil pressure sensor, which monitors whether the oil pressure is stable. I often check these components myself, like draining the oil pan and installing a new filter during an oil change. Once, the oil pump had an issue, causing abnormal engine noise, but fortunately, it was detected in time to prevent engine damage. Insufficient lubrication can lead to increased friction between parts, shortening the vehicle's lifespan. I believe regular oil and filter changes are crucial—spending a little money can protect the big engine. I recommend fellow car owners check the oil pressure every 5,000 kilometers to keep the operation smooth.
As an ordinary driver, my concern for the lubrication system stems from safety considerations. It mainly consists of engine oil, a container called the oil pan, a pump responsible for circulating the oil, an oil filter that removes contaminants, and oil passages throughout the engine. The oil lubricates the crankshaft and pistons, reducing friction and preventing overheating. I remember one time when the engine light came on while I was driving, and the mechanic said it was due to low oil pressure caused by a clogged oil filter, which nearly ruined the engine. I remind myself to change the oil every six months and check if the oil passages are clear. Proper lubrication makes the car more fuel-efficient and extends its lifespan. In daily maintenance, don’t overlook this small system—it can prevent major problems and save you from repair headaches.
