1Preliminary remarks
1.1Purpose of this manual
This Operation Manual belongs to the turbocharger with the identical
serial number (01), see the cover sheet of the Operation Manual and the
turbocharger rating plate.
Operation Manual
This Operation Manual helps familiarise the user with the turbocharger
from ABB Turbocharging and how to use it as intended.
It provides important information in order that the turbocharger can be
operated safely, correctly and efficiently.
This Operation Manual complements and expands existing national regulations concerning work safety and accident prevention.
Target group
This Operation Manual is intended for engineers and qualified mechanics who are responsible for operating the engine and the turbocharger
installed on it.
Availability of operation manual
Page 3 / 113
An operation manual must be available at all times at the place where
the turbocharger is used.
Everyone who operates or works on the turbocharger must have first
read and understood the operation manual.
The turbocharger is a turbomachine consisting of the following main
components:
¡Turbine
¡Compressor
These are mounted on a common shaft.
Exhaust gases from the diesel or gas engine flow through the turbine
casing (10) and the nozzle ring (9) to impinge on the turbine (7).
The turbine (7) uses the energy contained in the exhaust gas to drive the
compressor wheel (13). The compressor draws in fresh air, compresses it
and then forces it into the engine's cylinders.
The exhaust gases escape into the ambient air through the exhaust gas
pipe, which is connected to the gas outlet flange (8).
The air, which is necessary for operation of the diesel or gas engine and
is compressed in the turbocharger, is drawn into the compressor wheel
(13) through the suction branch or filter silencer (1). It then passes
through the diffuser (3) and leaves the turbocharger through the outlet
on the compressor casing (2).
The rotor runs in two radial plain bearings (6), which are located in the
bearing flanges (11/12) between the compressor and the turbine. The
axial thrust bearing (5) is located between the two radial plain bearings.
The bearings are connected to a central lubricating oil duct which is supplied by the engine's lubricating oil circuit. The oil outlet is always at the
lowest point of the bearing casing (4).
1 Preliminary remarks / 1.3 Intended use of the turbocharger
1.3Intended use of the turbocharger
NOTICE
This turbocharger supplied by ABB Turbocharging has been developed
for use on diesel engines to generate the volume of air and the charging pressure required to operate the engine.
The enginebuilder has provided ABB Turbocharging with information
regarding the intended use of the engine, from which the operating
limits specific to the turbocharger shown on the rating plate, such as
operating speeds, temperatures, exchange intervals / replacement intervals, have been derived.
Use in connection with a gas engine requires that the engine is not installed in a potentially explosive environment and that precautions are
taken to ensure that the engine room as a whole is classified as non-ex-plosive.
Any other use is considered to be a special application, which must first
be clarified with ABB Turbocharging. The manufacturer accepts no liability for any other type of use. If the equipment is used for any other
purpose, ABB Turbocharging reserves the right to reject all warranty
claims.

ABB Turbocharging recommends that, following a deflagration event,
the turbocharger undergoes an inspection of the following points:
¡Position of the turbine and compressor casings to the bearing casing
¡Shifting of the bearing casing in relation to the bracket
¡Cracks in casings
If during external inspection anomalies are found or if a particularly
strong deflagration event has taken place, it is also recommended to
check the bearings of the turbochargers before the next start. This inspection and evaluation must be carried out by an ABB Turbocharging
Service Station.
2 Safety / 2.9 Periodic checking of the pressure vessel
2.9Periodic checking of the pressure vessel
The pressure vessels used by ABB, such as those for wet or dry cleaning,
are so-called "simple pressure vessels".
¡The locally applicable legal regulations regarding periodic checks of
the pressure vessels must be observed.
¡The operating company is responsible for the safe operation of the
pressure vessel.
WARNING
Danger due to pressure vessels
The operating company must make sure the pressure vessels are in
proper working condition and monitor them. Necessary repair or maintenance work must be carried out without delay and the required safety
precautions must be taken.
u Pressure equipment must not be operated if it has defects.
Page 26 / 113
2.10Lifting loads
WARNING
Suspended loads
Loads not suspended in compliance with regulations may lead to personal injury or accidents with fatal consequences.
u Loads must always be fastened to technically perfect lifting gear
with sufficient loading capacity.
u Make sure the load is suspended properly on the crane hook.
u Do not let anyone stand beneath a suspended load.
Wear safety gloves to protect against mechanical hazards.
A carefully designed and installed oil supply, which functions in all possible operational conditions, is an important prerequisite for troublefree turbocharger operation.
The turbocharger is normally lubricated with oil from the engine oil circuit. If a separate lubricating system is used, then emergency lubrication
is also to be provided.
u Heed the instructions of the engine builder when selecting the lubric-
ating oil and oil-change intervals.
Oil filtration
Page 28 / 113
CAUTION
Depending on the turbine specifications and bearings used, varying
amounts of contaminants have to be filtered out of the lubricating oil
to avoid dangerous wear of the bearing parts.
The standard oil filter specification for the turbocharger is 34µm. This
means that contaminants larger than 0.034mm must be filtered out of
the oil with a separation efficiency >99%.
u Fit an accessory filter if engine oil filter is not efficient enough.
u If the engine is started cold and the flow resistance rises to above 0.5
bar due to deposits of dirt in the accessory filter, a bypass must open
which ensures that oil flows to the turbocharger by circumventing the
filter.
u Check that oil filters are clean before commissioning.
NOTICE
Also follow the enginebuilder's instructions regarding filter mesh and
separation efficiency.
Machine damage may result if the oil temperature at the oil inlet exceeds the permissible range.
u Keep the oil temperature at the oil inlet as specified in the following
table.

The recommended replacement intervals for compressor wheels and turbine wheels are defined depending on the operating conditions and
based on the safety concept (SiKo) for rotating parts. These intervals
can be found on the turbocharger rating plate.
Non-rotating components
Depending on the system-specific operating conditions, a distinction is
made between:
¡the replacement interval for the bearing parts and
¡the replacement interval for those non-rotating components that are
exposed to hot gases.
Decisive in this respect are various influencing parameters, which can
drastically shorten the replacement intervals of these parts in extreme
cases.
During the specified periodic service work, the individual components
are inspected for wear and, if necessary, replaced.

General maintenance work involves regular visual checks and cleaning
tasks which are intended to ensure the trouble-free functioning of the
turbocharger.
The maintenance points described here are differentiated as follows:
If mechanical cleaning is carried out too often, this can lead to damage
and corrosion on the components.
u If cleaning during operation is not sufficient to achieve acceptable
values regarding thermal load and engine performance, mechanical
cleaning of certain spots can be carried out.
u Perform mechanical cleaning, especially of the cartridge group, only
once within the service interval.
To allow you to observe the standard service intervals and to maintain a
high turbocharger efficiency, ABB Turbocharging recommends that the
cleaning procedure be carried out during operation. This allows the
thermal load of the engine to be kept low while ensuring maximum fuel
efficiency.
u Dispose of dirty water and cleaning agents in an environmentally
compatible manner, professionally and in accordance with valid local
regulations.
5 Maintenance / 5.2 Cleaning the compressor during operation
5.2Cleaning the compressor during operation
General
The contamination of the compressor stage (compressor wheel, wall insert and diffuser) depends on the degree of purity of the air that is
drawn in.
Deposits can form in the flow channels if salt, oil mist, exhaust gas or
dust are sucked in with the air.
Consequences of contamination:
¡Impaired compressor efficiency
¡Higher exhaust gas temperatures
¡Increased fuel consumption
¡Increased rotor unbalance
Periodic cleaning of the compressor during operation prevents or delays
any major increase in contamination. It does not, however, replace the
regular service work, during which the turbocharger is completely dismantled and the compressor is cleaned mechanically.
NOTICE
If the coating of dirt is very thick and hard, the compressor can only be
cleaned manually when disassembled. This cleaning must be carried out
by an ABB Turbocharging Service Station.
Page 46 / 113
Cleaning interval
The interval between periodic cleaning is very dependent on the operating conditions. In general, cleaning should be carried out every 25...100
operating hours.
Should the specified cleaning intervals prove incompatible with engine
operation, please contact ABB Turbocharging.
5 Maintenance / 5.2 Cleaning the compressor during operation
Cleaning method
Cleaning the compressor while in operation is carried out as wet cleaning. This cleaning method is tested and approved by ABB Turbocharging.
Principle of wet cleaning
V-engines
To clean the compressor stage during operation, water is injected in
front of the compressor wheel through an injection pipe fitted in the filter silencer or the suction branch.
The water does not act as a solvent, but the contamination deposit is removed by the mechanical impact of the droplets. This is a very suitable
process, provided that the degree of contamination is not too high.
CAUTION
Corrosion and deposits when cleaning
Damage and impairment of turbocharger parts due to salt water and
cooling water additives
u Don't use salt water for cleaning, but only clean fresh water.
CAUTION
The injection pipe must on no account be connected directly via a cock
to a water pipe or a dosing vessel larger than the one supplied. This
prevents uncontrolled volumes of water entering the turbocharger and
engine, which can lead to serious damage.
In the case of V-engines with several turbochargers on each engine, we
recommend parallel cleaning of the compressors. This cleaning process
is faster and the risk of turbocharger surging is reduced.
Page 47 / 113
Sequential charging
In the case of sequential charging, care must be taken to ensure that turbocharger compressors are cleaned regularly, especially after periods of
operation in the lower performance range.
5 Maintenance / 5.2 Cleaning the compressor during operation
5.2.1Wet cleaning compressor using external water
pressure vessel (XC1)
Page 48 / 113
Approval by enginebuilder
These instructions for wet cleaning only apply when cleaning is carried
out with clean water and under the precondition that the enginebuilder
approves the process.
NOTICE
Supplying water from the externally mounted water vessel is suitable
only for those applications where a negative pressure exists in front of
the compressor wheel (not used for: blowers connected in front of the
compressor or high-pressure compressor stages with two-stage charging).
Operating state prerequisites for cleaning compressor with XC1
NOTICE
To be able to carry out a satisfactory cleaning process which has been
tested and is recommended by ABB Turbocharging, the following prerequisites must be fulfilled:
u Run engine at load from 50…85%.
u Start cleaning cycle according to following description Wet cleaning

ZVessel
u Remove sealing plug (X).
u Fill the vessel (Z) with clean water.
u Screw in the sealing plug.
u Push the valve activator (Y) against the spring and hold for 10 to 15
seconds until the entire volume of water has been injected.
u Do not repeat the cleaning cycle until a stabilisation period of at least
10 minutes has elapsed.
NOTICE
Whether or not cleaning has been successful can be seen from the charging or flushing pressure and also from the exhaust gas temperatures.
If the cleaning process is unsatisfactory, it can be repeated up to 2
times.
If the cleaning result is still not satisfactory after three attempts and
the engine values are also unsatisfactory, we recommend that you have
the turbocharger inspected and cleaned by an official ABB Turbocharging Service Station.
5 Maintenance / 5.3 Turbine cleaning during operation
5.3Turbine cleaning during operation
The combustion of fuels such as heavy fuel oil (HFO) in diesel engines
produces contamination of the turbocharger's turbine components. In
combination with a high exhaust gas temperature, poor quality fuel can
lead to particularly hard deposits on the nozzle ring and especially on the
gas outlet flange.
ABB Turbocharging recommends the use of fuels with low ash, sulphur,
sodium and vanadium contents.
Consequences of contamination:
¡Poor turbine efficiency
¡elevated exhaust gas temperatures
¡higher charging and ignition pressures as turbocharger speed rises
¡lower engine performance.
¡After stopping the engine, the rotor can become stuck in contamina-
tion deposits.
Page 50 / 113
Experience with turbocharger operation shows that the intervals
between overhauls can be extended if cleaning while in operation is carried out periodically. Wet cleaning the turbine, as described below,
should be used for 4-stroke applications when there are heavy deposits
from, for example, HFO.
Under no circumstances is periodic cleaning of the turbine during operation a substitute for the service work carried out when the turbocharger
is completely dismantled and cleaned mechanically.
Turbines which are very heavily contaminated cannot be cleaned this
way any longer. In this case, the contaminated components must be
mechanically cleaned by an ABB Turbocharging Service Station.
NOTICE
Regular cleaning
Regular turbine cleaning during operation prevents or delays excessive
build-up of contamination.
Cleaning intervals
The interval between periodic cleaning is very dependent on the operating conditions. In general, cleaning should be carried out every 50 to 200
operating hours.
NOTICE
Cleaning intervals
Should the specified cleaning intervals prove incompatible with engine
operation, please contact ABB Turbocharging.
5 Maintenance / 5.3 Turbine cleaning during operation
Cleaning method
Turbine components are cleaned during operation by using the wet
cleaning method described below. This cleaning method is tested and
approved by ABB Turbocharging.
The turbine casing design and the type of turbine casing seal are decisive for the choice of cleaning method.
NOTICE
Approval by engine manufacturer
The prerequisite for wet cleaning is that the engine manufacturer approves the method and his instructions are followed.
5.3.1Wet cleaning methods
Process with short water injection time (3 x 30 seconds cleaning)
The cleaning process with short water injection time is used for turbocharger designs without additional sealing by means of C-rings.
The process is based on the principle of thermal shock in combination
with a subsequent flushing phase.
Process with long water injection time (10 minutes cleaning)
The cleaning process with a long water injection time is used for turbocharger designs with additional sealing by means of C-rings.
Based on a 10-minute injection phase, this cleaning process utilises the
water solubility of the dirty deposits.
NOTICE
Choice of cleaning method
If you need information about the choice of cleaning method (short /
long), you can contact the engine builder or an official ABB Turbocharger service station.
5 Maintenance / 5.3 Turbine cleaning during operation
5.3.2Prerequisites
CAUTION
Risk of corrosion and deposits
Impairment and damage of turbocharger by salt water and cooling water additives in flow ducts
u Don't use salt water for cleaning, but only clean fresh water.
u Avoid corrosion on casing inner surfaces.
u Let engine run for 10 minutes after wet cleaning.
CAUTION
Maximum temperature in front of turbine during cleaning
When cleaning, the temperature in front of the turbine will rise and can
heavily stress the material of turbine components. The temperature at
the turbine inlet can be up to 100°C higher than the exhaust gas temperature after the cylinder. This should be taken into consideration
when setting the operating point before cleaning.
u Don't exceed maximum temperature in front of turbine when clean-
ing.
Page 52 / 113
CAUTION
Impermissible thermal stressing and flooding of the turbine
Smaller volumes of water can result in poor cleaning. Larger volumes of
water lead to impermissible thermal stressing of the turbine components and can cause flooding of the turbine.
u Be absolutely sure to observe turbine cleaning parameters.
NOTICE
V-engines
In the case of V-engines with several turbochargers on each engine, we
recommend parallel cleaning of both turbochargers. This cleaning process is faster and the risk of turbocharger surging is reduced.

geometry
The type of bearing can be determined by measuring the rotor run-out
time. To do so, the rotor must be pushed by hand, once to the left (L)
and once to the right (R), with a force as close to the same in both directions. The resulting run-out times until the rotor comes to a stop are
measured for the anticlockwise and clockwise rotations and then compared. With standard radial bearings, the run-out time for anticlockwise
and clockwise rotating rotors is the same.
If one run-out time is at least 1.5times longer than the other, then radial
bearings with a special bearing geometry are installed. The following B
clearances are valid for these special bearings.
