Technical specification
The fuel supply of the gasoline pump is insufficient. The fuel supply of the gasoline pump depends on the stroke of the pump membrane. If the stroke is large, the pump volume should be more; However, the amount of fuel pumped by the gasoline pump is bound to be small. The engine consumes more fuel, and the amount of fuel pumped by the gasoline pump is bound to be large. If the engine consumes more fuel, but the actual fuel supply is small, this situation is that the fuel supply of the gasoline pump is insufficient, and the oil level of the carburetor float chamber will decrease, and the engine power will be insufficient.
Fuel Pump Control Circuit Principal3360 The fuel pump has three control circuit modes: ECU controlled fuel pump control circuit, switch controlled fuel pump control circuit, and speed controlled fuel pump control circuit. Consider heat dissipation, sound insulation, air resistance, etc.
The function of the fuel pump is to suck fuel from the fuel tank, pressurize it and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure. Fuel pump is a professional term in the automotive parts industry. It is one of the basic components of the fuel injection system of EFI vehicles. It is located inside the fuel tank of the vehicle. When the engine is started and running, the fuel pump works. If the engine is stopped and the ignition switch is still on, the HFM-SFI control module turns off the power supply of the fuel pump to avoid accidental ignition. The fuel pump consists of a motor, a pressure limiter and a check valve. The motor actually works in the fuel in the oil pump housing, which can lubricate and cool the motor. The check valve is installed at the oil outlet, the pressure limiter is located at the pressure side of the oil pump housing, and there is a channel leading to the oil inlet. At present, the vane type electric fuel pump widely used in automobiles has the advantages of large pumping capacity, high pumping pressure, stability, low noise, long service life, etc. When troubleshooting the vehicle fuel pump that has been used for a long time, it is not allowed to conduct a dry test on the fuel pump, because after the fuel pump is removed, there is fuel residue in the pump housing. Once the brush and the commutator are poorly contacted during the power on test, sparks will be generated to ignite the fuel in the pump housing, causing explosion.
