The working principle of Carter 320 electronic fuel pump is as follows: After the electronic fuel pump is powered on, it uses the principle of electromagnetic induction to rotate in the electromagnetic field. The ECU controls the DC motor to power on and drive the impeller to rotate, the volume at the oil inlet chamber increases, and a vacuum is formed to absorb oil. Under the action of centrifugal force, the blades are close to the pump housing, and the oil is driven out of the oil inlet chamber through a narrow gap. The volume at the oil outlet is reduced, and high-pressure oil is pumped out from the oil outlet.
- Fuel supply: Fuel is sucked out of the fuel tank and delivered to the engine's fuel injection system through the fuel pipeline to meet the engine's combustion needs.
- Fuel pressure regulation: It has the function of fuel pressure regulation to ensure the stability of the fuel pressure in the engine's fuel injection system. By adjusting the working parameters, such as the regulating valve or pressure regulator, the fuel supply pressure is controlled to adapt to different loads and working conditions.
