An engine oil pump comprises a main pump (1) and an auxiliary pump (2-4). The main pump and the auxiliary pump use a segmented structure. The main pump and the auxiliary pump share one drive shaft (26). The main pump and the auxiliary pump are each provided with an oil inlet port (8-11) and an oil outlet port (12-15). Also provided is an engine lubrication system, comprising an oil bottom shell, an engine lubricating oil passage, and an oil collection container. The oil inlet port of the auxiliary pump is in communication with the oil bottom shell, the oil outlet port of the auxiliary pump is in communication with the oil collection container, the oil inlet port of the main pump is in communication with the oil collection container, and the oil outlet port of the main pump is in communication with the engine lubricating oil passage. Thereby, it is ensured that when the engine operates at a large tilt angle, the lubricating oil can be continuously circulated in the engine to provide lubrication. |
