The common rail system is the main application of the high pressure common rail test bench, and the diesel injection system is corresponding to it. So what are the differences between the two systems? The common rail system is different from the previous diesel injection system driven by a camshaft. The common rail diesel injection system completely separates the generation of injection pressure and the injection process from each other. The solenoid-controlled fuel injector replaces the traditional mechanical fuel 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. The TAIXI high-pressure common rail test bench can be used at Set freely within a certain range. The fuel pressure in the common rail is controlled by an electromagnetic pressure regulating valve, which continuously adjusts the pressure according to the working needs of the engine. The pulse signal on the solenoid valve of the fuel injector controlled by the electronic control unit controls the fuel injection process. The amount of fuel injection depends on the fuel pressure in the fuel rail and the length of the solenoid valve opening time, as well as the liquid
The high-pressure common rail test bench is different from the ordinary test bench on the engine. The high-pressure common rail test bench engine is generally a diesel engine, and the traditional diesel engine relies on low-pressure oil circuit to high-pressure oil circuit. The high-pressure common rail test bench adopts the original BOSCH high-pressure common rail oil pump to generate 0~1600bar rail pressure. Industrial computer real-time control, windows operating system; oil measurement by sensor and display by 19” tactile LCD screen; query, storage and database creation; remote fault diagnosis can be realized.

The main characteristics of the high-pressure common rail test bench are that the high pressure in the common rail chamber is directly used for injection, which can eliminate the supercharging mechanism in the injector; moreover, the common rail chamber is continuously high pressure, and the driving torque required by the high-pressure oil pump is much smaller than that of the traditional oil pump.

Through the pressure regulating solenoid valve on the high-pressure oil pump, the oil pressure in the common rail chamber can be flexibly regulated according to the requirements of engine load condition, economy and emission, especially the low-speed performance of the engine is optimized. The solenoid valve on the injector controls the injection timing, injection quantity and injection rate, and also can flexibly adjust the injection quantity of pre-injection and post-injection and the interval with the main -injection under different working conditions.

The high-pressure common rail test bench can test the injectors and common rail pumps produced by Bosch, Siemens, Delphi and Denso; test the tightness of common rail pumps; test the internal pressure of common rail pumps and the proportional solenoid valve; test the gear pump performance of common rail pumps; detect the flow of common rail pumps; measure the rail pressure in real time, has the function of high-pressure protection; query, store and generate databases. The product features stable performance, accurate measurement, plexiglass protective door, easy to operate and more safe observation. The pulse width and frequency of the driving signal of the fuel injector can be adjusted; the injection times or injection time of the fuel injector can be set freely; the short-circuit protection function; the measurement is accurate, the operation is simple, low-noise and energy-saving.
