What is the composition of the engine lubrication system?

The composition of the engine lubrication system is: 1. Oil supply device: includes oil pump, oil passage, oil pipe, and pressure relief valve; 2. Filtration device: includes oil strainer, coarse filter, fine filter, and bypass valve; 3. Instrument and signal device: includes clogging indicator, pressure sensor, oil pressure alarm, indicator light, and pressure gauge. The lubrication methods of the engine lubrication system are: 1. Pressure lubrication: a lubrication method that supplies oil to the friction surfaces at a certain pressure; 2. Splash lubrication: a lubrication method that uses oil droplets or mist splashed by moving parts during engine operation to lubricate the friction surfaces; 3. Grease lubrication: a method of lubricating the working surfaces of parts by periodically injecting grease through grease fittings.
The engine lubrication system functions like the circulatory system of life, primarily composed of several core components. As someone who frequently deals with car maintenance, this system starts with the oil pan storing the engine oil, followed by the oil pump pressurizing and delivering the oil to all necessary lubrication points. The oil filter is crucial—it removes metal debris and impurities to keep the oil clean. The oil then flows through oil passages to lubricate critical bearing components like the crankshaft and camshaft, reducing friction and cooling the engine. I’ve also noticed that an oil cooler helps dissipate heat during high temperatures, preventing the oil from thinning and losing effectiveness. During maintenance, regularly changing the oil and filter is key to preventing component wear—neglecting this can lead to premature engine failure. Overall, this system ensures smooth engine operation and extends its lifespan, making it a fundamental maintenance priority for any car owner that cannot be overlooked.
In daily driving, I always remind myself of the importance of the lubrication system, which consists of components such as the oil pan storing oil, the oil pump circulating oil, the filter purifying oil, and the oil passages delivering oil to critical parts. Imagine the oil pan collecting oil at the bottom of the engine, while the oil pump acts like a heart, pressurizing and circulating the oil. The filter removes contaminants to prevent clogging the oil passages and compromising lubrication. When changing the oil, I noticed that if the filter isn’t cleaned promptly, accumulated impurities can reduce oil pressure and increase engine noise. The oil cooler proves useful during hot summers or long-distance driving, preventing overheating. Keeping these components in good condition ensures my car runs quieter and lasts longer.
