The working principle of a car oil pump: The fuel pump mainly relies on the electric motor to drive the turbine blades to rotate, and relies on the centrifugal force to suck in fuel from the inlet hole and discharge it from the outlet hole.

The form of automotive fuel pump: Currently, most cars use vane type electric fuel pumps. The blade type electric fuel pump has the advantages of large pump oil volume, high pump oil pressure, stability, low noise, and long service life.

The function of the car oil pump: As the most basic component in the engine fuel supply system, the fuel pump is responsible for extracting fuel from the tank during the engine's operation, and continuously delivering it to the engine through the fuel supply pipeline at a certain pressure. Then, the high-pressure oil pump pressurizes it again, and provides a quantitative amount of fuel for each cylinder according to the engine's working order.
