Model: CRDI 786 C

Model: Mini CRDI 101 C

• Pressure in the system (0 - 2000 BAR) by controlling the percentage opening of the fuel rail pressure control valve / solenoid / DRV from 0 - 100 %
• The injector pulse width (W) - Which determines the volume of delivery per spray.
• Injector frequency of spray / RPM of engine (N) - Which controls the number of sprays per second.
• Monitor the fuel rail pressure (Also the system pressure) which is displayed digitally on the CRT 7000 LCD screen and also on the computer software screen , which is read constantly from the pressure sensor mounted on the fuel rail.

The CRDI 787 C test bench is a dedicated common rail injector, pump and fuel rail testing bench designed for quickly testing all kinds of common rail injectors, pumps and fuel rails of Bosch, Delphi, Denso and Siemens make (Injectors of both Solenoid and Piezo technology can be tested)

It is used to diagnose the Faulty Common rail injector by testing it for its spray pattern, Output delivery to back leakage ratio, Full load delivery, Low load delivery etc.

Features:

• This bench is also capable of testing the conventional diesel pumps such as inline, rotary / VE, P type, DPC pumps, etc. up to 8 cylinders.
• The test database contains over 2300 test-plans for Common Rail electromagnetic and Piezo injectors and CR pumps.
•  Injector coding is supported in Bosch, Denso and Delphi CR injectors
•  The unit is inbuilt with electronic digital measuring unit / flow sensors, which automatically measure and display the main supply / output and return / back leak flow of injectors and pumps. The values are automatically compared with the stored test plan values.
• User can operate the unit in Automatic mode, Test plan mode and Manual mode as well. Also, the user has the capability of creating and adding their own test plan to the computer / software.

User can also diagnose faulty common rail pumps if they are not developing sufficient pressure / if the solenoid (Fuel metering control valve) on the pump is not functioning well / return flow of the pump is too high. Common Rail Pumps that can be tested include Bosch CP1 / CP2 / CP3, Delphi CRSP, Denso HP0 / HP3 / HP 4 and the Siemens DCP pumps. User can also measure pump fuel return flow with the flow meter mounted on the test bench.The user can vary the pressure developed in the system from 0 – 2200 BAR by controlling the percentage opening of the Pressure control valve / solenoid mounted on the fuel rail fitted on this bench.

All test bench controls are through the HMI - Human machine interface touchscreen mounted on the computer. All test bench parameters are controlled and monitored through the HMI. User can set the test bench RPM, number of strokes, start and stop the collection of fuel in the test tubes, drain the test tubes, monitor fuel temperature, monitor inlet fuel pressure, switch on / off fuel supply motor, switch on/off main motor etc., all directly through the HMI touchscreen.

Test Bench Specifications:
