An engine oil pump includes an oil supply mechanism and an adjustment mechanism. The oil supply mechanism includes an oil inlet, an oil outlet, an oil passage with two ends communicating with the oil inlet and oil outlet, and a driving gear and a driven gear located in the oil passage. The driving gear and driven gear are engaged at a selected depth to determine oil supply amount passing through the oil passage. The adjustment mechanism includes a housing and an actuation piston fastened to the driven gear. The housing has an engine oil duct on the periphery including one end communicating with the oil outlet and introducing engine oil from the oil outlet to one side of the actuation piston for storing. The actuation piston is pushed by pressure of the engine oil to drive the driven gear to move, and the oil supply amount is also changed. |
