of the fuel pump, means at the bottom of the vehicle, fuel will be sucked out from the fuel tank, the pressure supplied to the supply pipe and the means used for engine combustion chamber, the fuel pressure regulator when working with a certain fuel pressure, It is one of the basic components of EFI car fuel injection system.
1. The structural characteristics of the fuel pump
of the fuel pump, a pressure limiter, check valve constituted by an electric motor, the electric motor actual work in the oil pump housing of the fuel, the fuel oil can lubricate and cool motor, because nothing can shell firing, it generally does not produce any danger; check valve installed in the oil outlet, the pressure restrictor located in the pump pressure side of the shell, with a passage leading to the oil inlet. ZYB ignition type booster pump for conveying diesel fuel, heavy oil, residual oil, medium fuel oil, road and bridge construction is particularly suitable for mixing station pump in the fuel pump of the burner, is ideal to replace imported products; similarly ammonia, benzene and the like or highly volatile liquids having a low flash point characteristics suitable for delivery.
2. The fuel pump inspection Note
Upon detection of the fuel pump, engine, and other electronic components must not be in the operation state, the operation thereof will affect the voltage applied to the fuel pump, will also effect of the current readings, affect the inspection results.
