High Quality Diesel Fuel Injection Pump BHF4PM100003 Engine Parts for FAW 1041

In the car behind the orderly operation, the fuel pump plays a vital but little-known role. It is hidden in the tank, day after day, minute by minute labor, a steady stream of fuel for the engine, known as the car's power “lifeline”.

The moment the fuel pump is turned on to work, the motor takes the lead in “waking up”. After the motor is energized, the internal rotor rotates quickly, by virtue of the principle of electromagnetic induction, electrical energy is efficiently converted into mechanical energy, which plays the prelude to the fuel delivery. The motor is like the “power engine” of the whole fuel pump, with a stable and strong rotation speed, laying a solid foundation for the subsequent process; as long as the vehicle is energized, the motor will be on standby, waiting to open the work cycle, and never dragging its feet.

High-pressure fuel leaves the pump body, rushing non-stop to the fuel filter. Filter as a harsh “security inspector”, full of fine mesh filter, any small impurities, particles are not to muddle through; it sieve out impurities, just to let the pure fuel to arrive at the injector nozzle. Injector nozzle is the “terminal” of the fuel pump delivery chain, but it is also the key node of the fuel gorgeous “transformation”. High-pressure fuel is atomized here into countless tiny oil droplets, like a fine mist, evenly sprayed into the engine cylinder; these oil droplets and air quickly and accurately mixed to form an excellent combustible mixture, just a spark plug gently a little fire, a moment to burst out of the surging energy, pushing the piston back and forth, into a strong power to drive the vehicle.

Fuel pump operation throughout the whole process, each link is closely linked, interlocked. It can not have the slightest slack, once the “strike”, the engine instantly “food”, the vehicle will be paralyzed on the road. Moreover, in order to fit the different working conditions of the vehicle, the fuel pump also has to flexibly adjust the output pressure and flow; idle, low-profile delivery of a small amount of fuel to maintain the operation; high-speed speed, power demand increases, instantly open the full horsepower to increase the amount of fuel supply. It is this precise, stable and efficient operation mechanism that enables the fuel pump to stand firm in the automobile power system and become the indispensable key “heart” behind the scenes, driving the wheels forward silently but powerfully.
