Electrically controlled injectors

The test bench DIT31 is a modular solution to test the common rail injectors (the additional TC38 triggering unit is required) as well as the conventional and 2 stage (double spring) diesel injectors.
The applied technology allows the test parameters to be determined reliably on each injection, with greater precision and resolution than using on average long test cycles to collect a measurable quantity of fuel.

Main features:
- Main tank 3 lt. with 15 micron filter
- Separated container for the collection of the contaminated liquid
- Large atomization chamber with smoke extraction and halogen lamp
- Pneumatic operated pump unit, the standard version is suitable up to 1400 BAR (compressed air 8-10 BAR is required). Special versions can be installed as optional to generate more pressure and flow.
- Pneumatic vice for the automatic clamping of the injector
- Digital manometer with the reading scale selection (BAR/PSI)
- Printer to generate the test report
- Program for conventional injectors: (1) measurement of the NOP (nozzle opening pressure) and calculation of the back-leakage time.
- Program for Double-spring injectors: (2) measurement of the NOP1 (1st stage) and NOP2 (2nd stage), calculation of the back-leakage time and determination of the K factor.
- 2 programs for common rail injectors: (3) identification of the return flow (leakage time), (4) of the opening delay, the injection time and the injected fuel quantity (dp).
- 24 months warranty. User's and servicing manual in English language.

TC38 - Injector triggering unit for common-rail injectors.
This unit has been developed as a module, to be used in two main applications:
- in conjunction with the DIT31 test bench, to test any common rail injector
- in conjunction with the ERT45R simulator, to make running the complete common rail system (pump+rail+injectors) on any test bench.
Main features:
- Triggering command for electromagnetic actuators (always provided)
- Triggering command for piezoelectric actuators (provided as optional, by the CRP extension)
- Ready to multiple injection technology (pre-injection, main injection, recovery injection)
- no manual adjustment is required, in fact all the parameters necessary to generate the appropriate pulse(s) are memorized in special smartcards (triggering cards)
- Basic triggering cards are provided to acquire the test parameters of any brand new injector. These figures can be used to compare the test results of injectors having the same part number.
- In addition to the basic triggering cards, specific triggering cards (complete with ready-to-use test data) are available for the some of Bosch, Delphi, and Denso injectors.
- when used with ERT45R simulator, the RPM input is available for the dynamic triggering till 4 injectors, automatically in specific way at different speeds. Multiples of additional 4 injectors can be added, as option.
