car engine lubrication system || How lubrication system works

A car engine lubrication system ensures that the engine's moving parts operate smoothly by reducing friction and preventing excessive heat. Here's how it works:
Engine Oil Reservoir: The system begins with the engine oil reservoir, typically located in the oil pan at the bottom of the engine. This reservoir holds the engine oil when the car is not running.
Oil Pump: When the engine starts, the oil pump is activated. It's usually driven by the engine's crankshaft. The pump draws oil from the reservoir and pressurizes it.
Oil Filter: The pressurized oil is sent through an oil filter. The oil filter removes dirt, debris, and contaminants from the oil, ensuring that only clean oil flows into the engine.
Oil Passageways: The filtered oil is then directed through a network of passageways in the engine block and cylinder head. These passageways lead to critical engine components such as bearings, camshafts, and valve lifters.
Lubrication of Moving Parts: As the oil flows through the engine, it coats and lubricates the various moving parts, such as crankshaft bearings, piston rings, and camshafts. This lubrication reduces friction, which in turn reduces wear and tear on these components.
Cooling: Engine oil also helps dissipate heat generated during combustion. It absorbs heat from hot engine components and carries it away, contributing to the engine's cooling.
Return to Reservoir: After lubricating the engine's parts and absorbing heat, the oil returns to the oil pan, where it can cool down before the cycle repeats.
Oil Pressure Monitoring: Most modern cars have an oil pressure sensor or gauge to monitor oil pressure. If the pressure drops too low, it can indicate a problem with the lubrication system or low oil levels.
Regular maintenance, including oil changes, is crucial to keep the lubrication system functioning effectively. It ensures that the engine remains properly lubricated and can operate efficiently for a long time.
