CRS-3 is a common rail system tester that can simulate the engine electronic control unit (ECU) to issue driving signal to drive Bosch, Denso, Delphi high pressure common rail pump and solenoid valve common rail injector. Combining with traditional high pressure pump test bench, CRS-3 adopts high pressure common rail pump as its high pressure fuel source to test injector and finishes the testing of injecting delivery, return-fuel delivery and injector atomization under different common rail pressure and injecting frequency. By testing high pressure fuel delivery under different speed and different pressure, it can test the situation of high pressure pump.
1.1 To integrate fuel pump control module and an injector control module.
1.2 Fuel pump control module includes 2 sets independent controlling PWM output, common rail pressure sensor signal input, and add a new function of driving 3 DRV valves at the same time.
1.3 Injector control module includes 1 set electromagnetic coils driving output.
1.4 Display by 5.7 inch screen. Operation convenient and direct.
Fuel injection frequency and fuel injection pulse width are adjustable. Driving signal has short-circuited protection. This tester is provided with complete connectors.
