Carbon Zapp DS2R-A
Tester wtryskiwaczy Common Rail Carbon Zapp DS2R
Device for cleaning and testing of electromagnetic and piezoelectric Common Rail injectors:
▪ Bosch electromagnetic CRI and CRIN
▪ Delphi, electromagnetic
▪ Denso, electromagnetic, also with resistance above 2.5 Ω, 2- and 4-pin
▪ Bosch piezoelectric
▪ Denso piezoelectric
▪ VDO/Siemens/Continental piezoelectric.

Carbon Zapp DS2R-A had a world premiere at the Automechanika fairs in Frankfurt in September 2014 and replaced the older model Carbon Zapp DS2i.

Carbon Zapp DS2R-A has the same efficient internal cleaning function as CRU2R, but its capabilities in the field of injector testing are limited compared to CRU2R. Only CRU2R has advanced measuring system capable of accurately measure all doses including the injection of small pilotage doses.

DS2R-A contains built-in database, covering most of the parameters of injectors, but the measurement is done by filling of glass cylinders. Read of the parameters is done by the user himself. As a result of a lack of electronic measurement, it is not possible to carry out test in a completely automatic mode or print it just as it is and the measurement is not as accurate.
There is however the possibility to manually transfer the data from the volumetric tubes to the built-in tablet inside of the device and therefore print the protocols. Some advanced features may not be available in DS2R also. The device is not suitable for generating of new codes for the injectors.

Due to these limitations, the Carbon Zapp DS2R-A is treated as used mainly for cleaning and preliminary testing of the injectors.

DS2R-A is suitable as a base device to connect UIPR attachment for servicing unit injectors.
DS2R-A with volumetric tubes in conjunction with UIPR mainly provides professional cleaning of unit injectors, and preliminary test on volumetric tubes. More details can be found in the section "Zapp UIPR".

The following tests can be carried out on Carbon Zapp DS2R-A:
▪ leak test and examination of return volume with no electrical steering
▪ test for electrical parameters, such as: resistance, inductance, capacitance
▪ test the injection doses at several points depending on the load
▪ the injector opening pressure measured with current profile
▪ the injector response time in µs from its electrical signal to the actual opening. In addition, the device counts the impulses and checks whether the generated current signal corresponds to the number of actual injections.

It is possible to test Common Rail injector spray pattern in a specially prepared for this glass spray chamber.
In addition with DS2R-A there is also delivered 1.5 liter ultrasonic bath.
DS2R-A device has a built-in tablet with Android.
DS2R-A kit contains harnesses and adapters necessary for connecting electrics and hydraulics of injectors from passenger cars.

Warranty: 2 years.

You can connect DS2R-A to an attachment for cleaning and preliminary testing of the complete unit injectors named Carbon Zapp UIPR.
The device has additional equipment, including metal portable stand.


Tester wtryskiwaczy Common Rail Carbon Zapp DS1R
Carbon Zapp DS1R
Carbon Zapp DS1R is a simplified version of the device DS2R. DS1R device has been designed for simple tests of injectors based on a static weight measurement of injection doses. DS1R is not suitable for making new codes, and its accuracy is not sufficient for a full diagnosis of Common Rail injectors. DS1R is a device which, because of its low price can be regarded as the first device for the customer in the diesel business or can serve as an initial test platform in order to eliminate the major injectors failures like external leakage, big return flow etc. It can also be used in car workshops for the first assessment of the injectors, as well as Bosch EPS 118 tester.
