Principles of Engine Lubrication CombustionChambers 1 untitled high performance cam conrod Oil Pump | How It Works Many highly stressed, rapidly moving components in a modem internal-combustion engine need constant' lubrication if seizure or excessive wear are to be avoided. The function of an oil pump is to supply oil, under pressure, to those parts. of the engine which require this positive lubrication. You don't need us to tell you that the oil pump is one of the most important engine ancillaries. The reliability of an engine depends largely on efficient lubrication, and at the heart of the lubrication system is the oil pump. If the oil pump fails, serious mechanical breakdown will quickly follow. The oil pump must therefore be, above all, reliable and long-lasting, and for this reason they are comparatively simple devices employing few moving parts and requiring little or no maintenance. The Gear Type Oil Pump The most common form of oil pump used to be the gear type. The Rotor Oil Pump Another form of oil pump, more common than the gear type, is the rotor variety.
