How the injector works

The common rail injector uses high-precision sensors to automatically detect the fuel injection and oil return under full load, idle speed, pre-injection and other working conditions, and can check the injector sealability, which is to test the performance of diesel common rail injectors. The best equipment.
However, the advantages of common rail injectors are mainly:
1. Flexible control of fuel injection rate change, to achieve ideal fuel injection law, easy to achieve pre-injection and multiple injection, not only can reduce diesel engine NOx, but also ensure excellent power and economy.
2. The fuel injection is controlled by the solenoid valve, and the control precision is high. There is no bubble and residual pressure in the high-pressure oil passage. Therefore, within the operating range of the diesel engine, the fluctuation of the circulating fuel injection is small, and the oil supply of each cylinder is not Uniformity can be improved to reduce engine vibration and reduce emissions.
3. The injection pressure in the common rail system is flexible and adjustable, and the optimal injection pressure can be determined for different working conditions to optimize the overall performance of the diesel engine.
4. It can independently control the injection timing, and with high injection pressure (120MPa~200MPa), it can simultaneously control NOx and particulates (PM) within a small value to meet emission requirements.
   The main functions and features of the common rail injector: variable frequency drive common rail oil pump produces a maximum pressure of 250MPa; automatic closed loop control of rail pressure, display accuracy of 0.1MPa; built-in common rail injector standard database, free upgrade, users can also freely add data The common rail injector standard database is equipped with control waveform data of each type of injector, and outputs standard control waveform signals to the injector; it can detect various brands of high pressure common rail injectors such as Bosch; industrial computer motherboard, embedded windowsXP operation System; automatic measurement of fuel injection quantity and oil return quantity, screen display; report of test data can be generated, can be stored and printed; start oil quantity detection and detection of common rail injector opening pressure; detection of common rail injector sealing; detection Common rail injector atomization quality and other functions.
