How is an oil pump driven by the engine?

An oil pump is typically driven by the engine through a mechanical connection, often via a gear, chain, or belt linked to the crankshaft or camshaft. As the engine runs, the rotation of these components turns the oil pump, which circulates engine oil throughout the lubrication system. This ensures that moving parts are adequately lubricated and helps maintain optimal operating temperatures. In some modern engines, oil pumps may also be electrically driven but still rely on engine operation for optimal performance.
