Service of gasoline
injectors
The addition to the diesel
injectors workshop is the gasoline
injectors service station. For this
type of injectors there's no
technology of repair or internal
spare parts. There are parts
available but only simple ones, such
as o-rings, filters, caps. For this
reason, petrol injection service is
limited to ultrasonic cleaning with
current steering during the cleaning,
cleaning with chemical detergent,
back flushing and spray pattern
testing with a control of injection
doses.
Carbon
Zapp GS4
This device services gasoline
injectors both with multiple point
injection and throttle-body
injection. It's dedicated for
injectors mounted in the intake
manifold. For direct injection see
bottom of the page.
Device includes an external
ultrasonic bath. The process of
cleaning is performed with the
current signal put to the injectors.
After this the back flushing is done
to remove any dirt which residue
inside of the injector. The testing
procedure consists of the quality
test of spray pattern, leak test and
comparative test of injected doses.
Because of the similarity of the
gasoline low pressure injectors to
the CNG or LPG injectors their
servicing is also possible on the
GS4 unit.
The device is equipped with a metal
portable stand.
The device can also be configured
for 8 injectors.
Warranty: 2 years.
Carbon Tech GS4 also has the
possibility of servicing
electromagnetic gasoline direct
injectors eg. the TSI engines,
however, testing takes place only at
low pressure. Device can't work with
piezo injectors like from BMW. For
this type of injectors we recommend
Carbon Zapp GD1R or GDU2R device -
see below.
Carbon
Zapp GDU2R
Device for servicing electromagnetic and piezoelectric gasoline injectors with direct injection. In addition to the ultrasonic cleaning process is performed chemical cleaning inside of the injector.
The device tests the spray pattern and injection doses with pressure ranges from 30 to 550 bars. Built-in dynamic weight measurement system allows for comprehensive assessment of the injector.
GDU2R can print measurements. It checks also electrical parameters of injectors, including resistance, inductance, capacitance.
Its structure and functions are based on the device for diesel CR injectors Carbon Zapp CRU2R.
The device has a built-in tablet with Android system.
The device can be equipped with a piezoelectric response sensor and adapters for the injectors of the latest design.
Inside of the machine there is installed a low pressure pump (10 bar). This also allows a test of indirect injectors, however, this option should be considered as an additive. More functionality in the range of the traditional injectors is obtained on GS4 device. Therefore, for full service of petrol injectors the workshop must be equipped both in the GS4 and GDU2R.
What's new
- From 09.2016 GDU2R has a new feature called revitalization of a piezo stack of Siemens VDO injectors from BMW No. 10181010. It forms piezostack again, and most of the injections reaches the correct dosage parameters.
Manufacturer Warranty: 2 years.
Gasoline direct injection systems produced by Bosch, Siemens VDO, Continental, Hitachi, Denso and others are now used in almost every brand of vehicle, such as BMW, Mercedes, Ford, Opel, VW, Audi, Skoda, Seat, Toyota, Mazda.
Carbon
Zapp GDU4R
Device with similar features, as
GDU2R, in addition it tests up to 4
injectors at the same time. It can also regenerate 4 Siemens piezostacks at once.
GDU4R can't have chemical cleaning
system, only GDU2R has. Its
construction and features are based
on well-known Carbon Zapp CRU4R
device for diesel injectors.
GDU4R device has a built-in tablet
with Android.
Carbon
Zapp GD1R
Carbon Zapp GD1R is a simplified version of the device for gasoline direct injectors. Simple tests of injectors are based on a static weight measurement of injection doses. It works with maximum pressure of 300 bars and the regulation in done manually by regulating knob. GD1R because of its low price and simplicity can be regarded as the first device for the customer in the GDI business or can serve as an initial test platform in order to eliminate the major injectors failures like external leakage etc. It can also be used in car workshops for the first assessment of the injectors.
For complex diagnostic, servicing and testing of GDI injectors we recommend GDU2R or GDU4R machines.
