Description

Oil supply system and vehicle Technical Field The application relates to the technical field of vehicles, in particular to an oil supply system and a vehicle. Background During operation of the vehicle, the fueling system is required to supply fuel to the engine to power the vehicle. In the related art, the oil pump of the oil supply system has longer suction stroke, so the oil suction resistance is larger, on the basis, the oil suction end of the oil pump is easily affected by negative pressure to generate a large number of bubbles, so that parts such as the oil pump are damaged by cavitation and the like, the service life of the oil pump is shortened, and the fault risk of the vehicle oil supply system is increased. Disclosure of utility model The embodiment of the application provides an oil supply system and a vehicle, which are used for solving the problem of how to reduce the fault risk of the oil supply system.
