Introduce: The repair tester for Common Rail Injector simulates the outputs of an Engine Control Unit ( ECU) , by providing fuel injection control signals, of which the parameters may be set by a user, to drive the solenoid of a common rail injector. The CR injector is fed by a high pressure fuel source, which may be a mechanical manual pump or an electrical motor driven pump or a pneumatic driven pressure booster. Such a test device will fulfill the tasks of checking nozzle spray pattern, injector back leakage and solenoid condition. Design Features: 1. Modulated driving signal to ensure the safety of the solenoids of the injectors 2. Injector driving signal - Adjustable frequency and pulse width 3. Short circuit protection for solenoid driving signals 4. Rich accessories, ready to test Bosch, Denso and Delphi injectors
