Oil Pumps
Understanding Oil Pumps and Engine Lubrication
The oil pump stands as one of the most critical components in any engine's lubrication system. This essential part circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. Without a properly functioning oil pump, even the most advanced engine would quickly suffer catastrophic failure from metal-to-metal contact and excessive heat buildup.
This lubricates the bearings, allows the use of higher-capacity fluid bearings, and also assists in cooling the engine. By drawing oil from the oil pan and forcing it through a network of passages, the oil pump ensures that every critical surface receives adequate lubrication. The pump creates the pressure necessary to push oil through filters, coolers, and galleries before it reaches vital components like crankshaft journals, camshaft bearings, piston rings, and valve train components.
How Oil Pumps Work
Oil pumps operate as positive displacement devices, meaning they move a specific volume of oil with each rotation. Gear pumps, trochoid pumps and vane pumps are all commonly used. Most automotive oil pumps are driven directly by the crankshaft through gears or chains, ensuring that pump speed increases proportionally with engine RPM. This design creates higher oil pressure at higher engine speeds when lubrication demands are greatest.
The oil pump forces the motor oil through the passages in the engine to properly distribute oil to different engine components. After being drawn from the oil pan through a pickup tube and screen, the oil passes through the pump and then typically flows to the oil filter. From there, it travels through carefully engineered galleries machined into the engine block and cylinder head, delivering lubrication exactly where it's needed before draining back to the sump to begin the cycle again.
Why Oil Pump Quality Matters
Failing to properly lubricate an engine will result in engine failure. A worn or failing oil pump can lead to low oil pressure, inadequate lubrication, and rapid engine wear. High-performance and modern engines place even greater demands on the lubrication system, requiring pumps that can maintain consistent pressure across varying operating conditions and temperatures.
When selecting a replacement oil pump, consider factors like your vehicle's specific application, whether you run conventional or synthetic oil, and your typical driving conditions. Performance enthusiasts may opt for high-volume or high-pressure pumps designed to support modified engines, while standard replacement pumps restore original factory specifications for everyday vehicles.
