Description

 the repair tester to simulate the engine Control Unit (ECU) driving signals for a common rail injector of either solenoid technology or piezo technology, made by Bosch, Delphi, Denso and Siemens. The user is able to set the control parameters of fuel injection drive signals. By combining of a cri1000 tester and a high pressure fuel source, which may be a mechanical manual pump, or an electrical motor driven pump, or a pneumatic driven pressure booster, to feed the CR injector, the user is able to fulfill the tasks, such as nozzle spray pattern and injector back leakage, to check the CR injector with either solenoid or piezo technology.
