The common rail diesel injection system completely separates the generation of injection pressure and the injection process from each other. The solenoid valve-controlled injector replaces the traditional mechanical injector. The fuel pressure in the fuel rail is generated by a radial plunger high-pressure pump. The pressure is independent of the engine speed and can be freely set within a certain range. The fuel pressure in the common rail is controlled by a solenoid pressure regulating valve, which continuously adjusts the pressure according to the working needs of the engine. The pulse signal of the electronic control unit acting on the injector solenoid valve controls the fuel injection process. The amount of fuel injection depends on the oil pressure in the fuel rail, the length of time the solenoid valve is open, and the liquid flow characteristics of the injector nozzle. Fuel injection pressure is an important indicator of diesel engines because it is related to the engine's power, fuel consumption, emissions, etc. The common rail diesel injection system has increased the fuel injection pressure to 2600 bar.
