The function of high pressure common rail injection system tester is to imitate diesel engine ECU (Engine Control Unit). It provides driving control signals for six common rail injectors and one common rail high pressure pump to drive the common rail system. The driving signal parameters can be input by users themselves. It is convenient for maintenance personnel to judge and repair the common rail high pressure pump and injector. . RAT high pressure common rail injection system tester and standard diesel high pressure injection test stand work together, which can meet most of the maintenance requirements of high pressure common rail system and its components.
The product features are as follows: (1) Driving signal modulation to ensure the safety of maintenance of solenoid valve and common rail injector of common rail high-pressure pump; (2) By setting duty cycle of driving signal of high-pressure pump, the load of high-pressure pump and pressure of oil rail can be adjusted; (3) Pulse width and frequency of driving signal of injector can be adjusted, thereby adjusting injection quantity; (4) Instruments and tools. Overflow protection function with solenoid valve driving signal (5) Real-time measurement of oil rail pressure product functions are as follows: (1) fuel supply measurement test of high pressure oil pump (2) fuel supply pressure test of high pressure oil pump (3) rail high pressure test (4) common rail injector fuel supply (5) common rail injector opening pressure (6) common rail injector uniformity (7) common rail injector minimum. Injection volume (8) Maximum injection volume of common rail injector (9). At the same time, it can measure 4-6 injectors (10). Rapid running-in of injectors (11). Rapid running-in of high-pressure oil pump (12). Testable pumps can be tested by simulating actual working times: 1) BOSCH CP1/CP2/CP3 testable injector: 1) BOSCH 2 DELPHI 3 DENSO
Functional characteristics:
Integrated oil pump control module and an injector control module.
Oil pump control module, including two independent control PWM output, rail pressure sensor signal input, adding the function of driving three DRV valves at the same time
The fuel injector drive module includes 1 electromagnetic coil drive outputs and 1 piezoelectric crystal driver outputs.
* 5.7 "large screen display, manipulation is more convenient and more intuitive.
