Abstract

This utility model discloses an engine lubrication system, an engine, and a vehicle. The engine lubrication system includes an oil pump and an oil filter. The oil pump is connected to the oil filter through a first oil passage. Both the oil pump and the oil filter are connected to the engine block, and both are located at one end of the cylinder block along its length. In this embodiment, the oil pump and oil filter are compactly arranged, and their proximity shortens the length of the first oil passage, simplifies its structure, and reduces pressure drop loss.
