Location of fuel pump

The fuel pump is located in the car's fuel tank, which is located in the rear seat of the car, or under the trunk. The main function of the fuel pump is to supply fuel to the engine. The fuel pump delivers the high pressure and high pressure fuel pump to the fuel distribution pipe to ensure continuous fuel supply to the fuel injection nozzle. The fuel pump is composed of an electric motor, a pressure limiter, and a check valve. The electric motor actually works in the fuel in the oil pump housing, don’t worry, because there is nothing in the housing that can be ignited, the fuel can lubricate and cool the fuel motor, the oil outlet is equipped with a check valve, and the pressure limiter is located at the pressure of the oil pump housing. On the side, there is a channel leading to the oil inlet.
Built-in: integrated with the assembly, installed vertically in the mailbox. Features: Low noise, not easy to produce air resistance. The safety pipeline is easy to install.
External type: connected in series in the oil pipeline outside the mailbox. It is characterized by large installation freedom, convenient replacement and high air-tightness requirements.
At present, the fuel pump of most models is installed in the car mailbox and driven by electricity. The fuel pump is composed of a pump body, a permanent magnet motor and a shell. When the permanent magnet motor is energized, the pump body is driven to rotate, and the fuel is sucked in from the fuel inlet, flows through the inside of the electric fuel, and then is pressed out from the fuel outlet to supply fuel to the fuel system. The fuel flows through the inside of the electric fuel to cool the armature of the permanent magnet motor, also known as the wet fuel pump.

Inspection method of fuel pump performance edit voice

Some hard faults (such as failure to work, etc.) of automobile fuel pumps are easier to judge, but some intermittent soft faults are difficult to judge. In this regard, the method of detecting the operating current of the fuel pump by the automobile digital multimeter can be used to judge its performance, and the specific method is as follows.
(1) Put the automobile digital multimeter in the current block, press the function key (SELECT) to adjust to the direct current (DC) block, and then connect the two meter pens in series to the connection line of the tested fuel pump.
(2) Start the engine and press the dynamic recording key (MAX/MIN) of the automobile digital multimeter when the fuel pump is working, and the maximum and minimum currents of the fuel pump can be automatically recorded when the fuel pump is working. By comparing the detected data with the normal value, the cause of the failure can be judged.
