Common Rail System Tester For Denso-U2

This CR System Repair Tester targets Denso CR systems with an ECD-U2 pump. It simulates the Denso engine ECU, to drive two solenoids on an ECD-U2 pump and solenoids of 6 CR injectors.

A standard high pressure pump test bench with a CR system tester will achieve most tasks for repairing a Denso ECD-U2 system and the components, such as injection quantities, injector fuel return, nozzle injection spray atomization, pump condition and fuel rail pressure control.

Design Features
1. The tester meets the synchronization requirement to drive an ECD-U2 pump and 6 injectors.
2. Pump operation
    - Close-loop control of rail pressure to reach the required rail pressure
    - Manually adjust pump load
3. Injection operation
    - Synchronous fuel injection with the ECD-U2 pump
    - Manually adjust fuel injection frequency
    - Adjustable pulse width of injector driving signal
4. Short circuit protection for the output circuitry of the solenoid-driving signal
5. Rich accessories, ready to test a DENSO ECD-U2 system
