1 Safety / 1.9 Periodic check of the pressure vessels  
Explanations regarding the rating plate  
The recommended replacement intervals and the corresponding operating limits are jointly  
defined with the enginebuilder. This information is specific to the system.  
Operation above the indicated values nBmax, tBmax can considerably shorten the recommended  
replacement intervals. In such cases ABB recommends contacting the nearest ABB Tur-  
bocharging Service Station.  
nMmax, tMmax normally apply only when running at overload (110%) during trials on the engine  
test bed. These limit values can also be permitted during operation for special applications.  
Operation above nMmax and tMmax is not permitted.  
Non-observance of the recommended replacement intervals increases the risk of unpredict-  
able component failures.  
Locations of the rating plates  
The locations of the rating plates are defined in the Operation Manual, Chapter 4 Product  
description.  
1.9  
Periodic check of the pressure vessels  
The pressure vessels used by ABB Turbocharging, 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

1 Introduction / 1.4 Layout and function of the turbocharger  
Mode of operation  
The turbocharger is a turbomachine consisting of two main components, a turbine and a  
compressor. These components are mounted on a common shaft and form the rotor.  
In the turbocharger shown in the illustration, the exhaust gas flows through the gas inlet  
casing (06) and the nozzle ring (07) and arrives at the turbine (08). The turbine utilises the  
energy contained in the exhaust gas to drive the rotor. The exhaust gases then escape into  
the open air through the gas outlet casing (05) and the exhaust gas pipe connected to it.  
The rotor runs in two radial plain bearings, which are located between the compressor and  
the turbine in the bearing bush (04). The axial bearing is also a plain bearing. The plain bear-  
ings are connected to a central lubricating oil duct which is normally supplied by the lubric-  
ating oil circuit of the engine. The oil outlet is situated at the lowest point of the bearing  
casing (09).  
The compressor wheel (02) connected to the shaft draws in fresh air through the filter silen-  
cer (01) or the air suction branch. The air is compressed in the compressor and the down-  
stream diffuser (03) and then led to the charge air cooler via the compressor casing (10).  
Turbocharger version with compressor wheel cooling  
Fig. 2: Connection of the compressor wheel cooling  
Depending on the application, the turbocharger is equipped with compressor wheel cooling.  
With compressor wheel cooling, after the compressor air has cooled down by passing  
through the charge air cooler on the engine side, it is supplied to the turbocharger for cool-  
ing the compressor wheel.  
Cooling of the compressor wheel is compulsory to ensure the reliability and replacement in-  
tervals for the relevant operating conditions. In the turbocharger version with compressor  
wheel cooling, the cooling air is supplied through the lateral connection (15) in the bearing  
casing.

Speed differences with several turbochargers per engine  
The speeds of all turbochargers on an engine vary only slightly from each other in standard  
operation.  
The difference between the highest and the lowest turbocharger speed must not be more  
than 3 %, relative to the speed limit nBmax  
.
If this permissible range of difference is exceeded, the following steps must be carried out:  
u Reduce the engine performance immediately to the point at which the maximum tur-  
bocharger speed does not exceed 70 % of nBmax  
.
u If the engine cannot be stopped, it can continue to be driven at this reduced engine load  
or turbocharger speed.  
u If a turbocharger surges continuously, the engine performance must be reduced further.  
u Measure the temperatures in the air lines and gas piping from and to the turbochargers  
and compare with normal values. If clear deviations of temperature are found, the nearest  
ABB Turbocharging Service Station has to be contacted.  
u Check the pressure loss of the alternative air inlet and compare it with normal values.  
If the engine can be stopped temporarily:

The recommended replacement intervals for compressor wheels and turbine wheels are spe-  
cified based on the safety concept for rotating parts (SIKO) and dependent on the operating  
conditions. These intervals are shown on the rating plate of the turbocharger.  
Non-rotating components  
Depending on the system-specific operating conditions, a differentiation must be made  
between the intervals to be expected for:

¡
replacing the bearing parts and  
replacing the non-rotating components exposed to hot gas.  
A decisive role is played by various influencing parameters which, in extreme cases, can  
drastically reduce the replacement interval of these parts.

Cleaning the compressor during operation  
6.4.1  
Introduction  
Approval by enginebuilder  
The following instructions for wet cleaning only apply to cleaning with pure water and under  
the precondition that the enginebuilder approves the process.  
General  
The contamination of the compressor stage (compressor wheel and diffuser) depends on  
the degree of purity of the sucked-in air.  
Deposits can form in the flow channels if salt, oil mist 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. But it never replaces the regular service work where the turbocharger is  
completely dismantled and the compressor is mechanically cleaned.  
6.4.2  
Cleaning interval  
The time period between the periodical cleaning cycles depends greatly on the operating  
conditions. Cleaning should normally be done every 25 … 100 hours of operation.  
If the specified cleaning intervals are incompatible with operation of the engine, contact  
ABB.

Principle of wet cleaning  
Principle of wet cleaning  
To clean the compressor stage during operation, water is injected before the compressor  
wheel.  
The water does not act as a solvent. The coating is removed by the mechanical action of the  
impacting droplets. The process is particularly suitable as long as the contamination is not  
too advanced.  
CAUTION  
Corrosion and deposits when cleaning  
Salt water and cooling water treatment substances damage and adversely  
affect turbocharger parts.  
u Never use salt water, but only pure water for cleaning.  
CAUTION  
Volume of water  
Uncontrolled volumes of water can damage the turbocharger and the en-  
gine.  
u Never connect the water line without the orifice specified for the tur-  
bocharger.

Wet cleaning with direct water supply  
Prerequisites  
On V-engines with several turbochargers per engine, parallel cleaning of both turbochargers  
is recommended. This cleaning process is faster and reduces the risk of surging of the tur-  
bocharger.  
WARNING  
Increased stress on material  
During cleaning of the compressor at an engine load of 85 to 100 %, the  
stress on the material of the compressor-end turbocharger parts can be in-  
creased.  
u No personnel is allowed to be present in the vicinity of the turbocharger  
during compressor cleaning.  
u Compressor cleaning must be activated from the engine control panel.  
Wet cleaning operations for compressor with direct water supply  
u Trigger water injection according to the specifications of the enginebuilder.  
u Observe specified water pressure upstream of the connection to the turbocharger.  
u Operate engine for at least five additional minutes after cleaning.  
Not more than three cleaning cycles should be conducted consecutively.

Cleaning turbine and nozzle ring  
6.5.1  
Introduction  
Approval by enginebuilder  
The following instructions for wet cleaning only apply to cleaning with pure water and under  
the precondition that the enginebuilder approves the process.  
General  
The combustion of heavy fuel oil (HFO) has the effect of contaminating the turbine stage  
(turbine wheel and nozzle ring).  
The use of fuels with poor quality in conjunction with high exhaust gas temperatures can  
lead to extremely hard deposits on turbine components.  
ABB Turbocharging recommends the use of fuels with low ash, sulphur, sodium and vana-  
dium contents.  
Consequences of contamination:  
¡
¡
¡
¡
¡
Low turbine efficiency  
Elevated exhaust gas temperatures  
Increased charging and ignition pressures with increasing turbocharger speed  
Lower engine performance  
Rotor sticking after stopping the engine  
Periodic cleaning of the turbine during operation prevents or delays any major increase in  
contamination, but never replaces the regular service work where the turbocharger is com-  
pletely dismantled and mechanically cleaned.  
6.5.2  
Cleaning interval  
The time period between the periodical cleaning cycles depends greatly on the operating  
conditions. Cleaning should normally be carried out every 50 … 200 hours of operation.  
If the specified cleaning intervals are incompatible with operation of the engine, contact  
ABB.

6.5.3  
Cleaning method  
Cleaning of the turbine and the nozzle ring during operation is carried out by the cleaning  
method described in the following and is tested and approved by ABB Turbocharging:  
¡
Wet cleaning  
Wet cleaning makes use of various effects. These effects are used with varying levels of in-  
tensity, depending on the type of contamination:  
¡
¡
¡
Erosion  
The dirt is removed by the mechanical action of the impacting water droplets  
Solubility  
Water solubility of the dirt deposits in water  
Thermal shock  
Spalling of contamination due to temperature difference  
CAUTION  
Corrosion and deposits when cleaning  
Salt water and cooling water treatment substances damage and adversely  
affect turbocharger parts.  
u Never use salt water, but only pure water for cleaning.  
The influence of the cleaning water on the peripheral units (such as the boiler) must be clari-  
fied by the operator before commencing wet cleaning.  
The turbine-end components are cleaned at reduced engine load. The exhaust gas temperat-  
ure must not exceed the value specified in the cleaning instructions (see section Prerequis-  
ites).  
CAUTION  
Reduced service life of the components  
Failure to comply with the minimum stabilisation time before cleaning, the  
prescribed turbine inlet temperatures and the drying time after cleaning sig-  
nificantly reduces the expected service life of the components.  
u Comply with the cleaning parameters given in the tables (see Table 17:  
V-engines  
On V-engines with several turbochargers, we recommend the parallel cleaning of both tur-  
bochargers for each engine. This cleaning process is faster and reduces the risk of surging  
of the turbochargers.

6 Periodic maintenance / 6.5 Cleaning turbine and nozzle ring  
Procedure  
Fig. 26: Procedure Wet cleaning of turbine and nozzle ring  
The prerequisites and the operating state must be fulfilled prior to cleaning.  
u Make sure that the water supply (01) is connected, switched on and safeguarded.  
u Switch the 3-way valve (04) from scavenging air mode to water supply.  
u Set the necessary water quantity on the flowmeter (08) according to the table Cleaning  
49).  
u Shut off the water supply again by switching the 3-way valve (04) to scavenging air mode  
after the prescribed injection time has elapsed.  
The injection process is complete.  
u After cleaning, continue to operate the engine for at least 10 minutes without any load  
change.  
It is necessary to have the corresponding water pipe pressure in order to achieve the correct  
49). If there is insufficient water pressure, the water flow rate specified in the table will  
not be achieved. A reduced cleaning effect can be expected in this case.  
Repetition of wet cleaning  
The repeating of cleaning cycles one immediately after the other must be avoided as this  
can lead to excessive mechanical stress, hence reducing the operating life of the compon-  
ents.  
If the cleaning process is ineffective, the duration can be extended. If the injection time is ex-  
tended, it is important to ensure that no impermissible volume of water collects in the gas  
outlet casing. A drainage system should be installed for the gas outlet casing and opened  
during cleaning. If there is no drainage system, the amount of water injected can be mon-  
itored with a flowmeter in the water supply. The permitted amount of water must be de-  
termined with the help of an ABB Turbocharging Service Station.  
To be observed during cleaning  
¡
The action of the cleaning water on the peripheral units (such as boiler) must be clarified  
by the operator.

¡
¡
The exhaust gas temperature downstream of the turbocharger drops drastically during  
cleaning (typical turbocharger outlet temperatures during cleaning: 60...180°C).  
If there is no drainage of the gas outlet casing, the turbocharger speed and/or the gas  
inlet temperature must be monitored during the cleaning process. If the load is too low,  
water can collect in the gas outlet casing. Indicators for this are a sudden severe drop in  
the turbocharger speed or a very large increase in the gas inlet temperature. In such  
cases, the cleaning operations must be stopped and the cleaning cycle restarted with re-  
duced water pressure or higher engine load.

Normal behaviour, not a malfunction  
Turbochar-  
ger  
A slight amount of uniform wear at the circumference of the rotor components  
caused by slight local rubbing against adjacent components is permitted. This  
causes the compressor or turbine blades to be somewhat shortened. To prevent  
significant loss of efficiency, specific tolerances must be fulfilled.  
¡
If there is any doubt about the extent of the rubbing, contact an ABB Tur-  
bocharging Service Station.  
¡
Have a dimension check carried out by an ABB Turbocharging Service Sta-

Sporadic surge blows  
Surging of the turbocharger can occur during certain operating states, such as when redu-  
cing the engine load quickly when manoeuvring. When this happens, the flow direction in the  
compressor is momentarily reversed. Such sporadic surge blows do not impair the safe op-  
eration of the turbocharger.

9.1  
Possible emergency repairs  
CAUTION  
Machine damage in emergency operation  
The assembly of the locking device on the turbocharger is only permissible  
in emergencies. It is not permitted to lock the rotor for an engine test. Seri-  
ous damage to engine or property can be caused by non-compliance with  
the regulations in the event of an emergency.  
u The permissible turbocharger speed for the unlocked turbocharger may  
not exceed nBmax. Take note of the rating plate.  
u After locking the turbocharger, contact an ABB Turbocharging Service  
Station and find the nearest port.  
u Observe the safety regulations.  
u Follow the directives of the enginebuilder.  
WARNING  
Danger of fire and explosion due to lubricating oil leaks  
Leaking oil may ignite on hot surfaces. This can result in serious injuries to  
personnel or fatal accidents.  
u Cordon off danger area.  
u Raise the alarm and, depending on the situation, stop the engine.  
u Seal the oil leak.  
u Soak up oil and dispose of in an environmentally compatible manner.  
Wear safety gloves to protect against thermal hazards.  
If damage has occurred to the turbocharger and the engine has to be brought back into op-  
eration again as quickly as possible, the following emergency repair options are available:

Locking the rotor  
9.2.1  
Introduction  
CAUTION  
Cooling of a locked rotor  
Serious damage to engine or property can be caused by the overheating of  
intact turbocharger components.  
If the gas inlet is not blanked off, the lubricating oil supply remains switched  
on (see section Further information for operation of 4-stroke engines with  
locked rotor).  
u If there is a lubricating oil leak on the turbocharger, stop the oil supply.  
A locked rotor must be removed after emergency operation and checked for unbalance (see  
chapter Removing the cartridge group).  
The unbalance check must be carried out by an ABB Turbocharging Service Station.  
Exception  
The exception concerns customer requirements for test bed runs of new engines at a max-  
imum engine load of up to 25 %.  
In these cases, subsequent removal of the rotor is not required as the engine is only oper-  
ated briefly with a locked rotor.  
In these test bed runs, it is not allowed to remove any set screws from the compressor wheel  
when fitting the locking device (see section Fitting the locking device 99).

No further measures are necessary. The engine can be operated as a suction engine accord-  
ing to the instructions of the enginebuilder.  
4-stroke engine with several turbochargers  
Separate receivers  
In engines with separate air and exhaust gas receivers, no further measures are necessary.  
The engine can be operated as a suction engine according to the instructions of the en-  
ginebuilder.  
Common air receiver  
CAUTION  
Excessive speeds on undamaged turbochargers  
The speed limit nBmax specified on the rating plate of the turbocharger must  
not be exceeded. Serious damage to engine or property can be caused by  
excessive speeds.  
u Observe the speeds of the undamaged turbochargers.  
u Reduce the engine load if necessary.  
If the engine is equipped with a common air receiver and separate exhaust gas receivers, the  
bellows on the compressor outlet of the damaged turbocharger must always be removed  
and the air line on the engine side must be blanked off. Otherwise the undamaged tur-  
bocharger can spin "empty" (without load) and run at overspeed.  
Depending on the turbocharging system of the engine, the locked rotor is exposed to more  
or less strong pulses from the exhaust gas system. Especially in pulse charging (turbine cas-  
ing with more than one gas inlet), the locking device is heavily strained by this process.  
Therefore the following operating limits should not be exceeded:  
¡
In constant-pressure-similar systems (1 gas inlet), the engine can be operated at a max-  
imum engine load of up to 25 %. The pressure in the charge air receiver must not exceed  
0.9 bar overpressure.  
¡
In pulse charging (2 to 4 gas inlets), the engine can be operated at a maximum engine  
load of up to 20 %. The pressure in the charge air receiver must not exceed 0.5 bar over-  
pressure.

Mothballing the turbocharger  
10.1  
Taking the engine out of operation for up to  
12 months  
State of the engine lubricating oil  
The turbocharger normally remains attached to the engine. The measures to be taken for  
mothballing the turbocharger depend on the state of the lubricating oil. No measures are re-  
quired under the following conditions:  
¡
¡
Acid number (TAN) < 2 mg KOH/g  
The engine lubricating oil is replaced by a preservative oil and circulated with the pre-lub-  
rication pump before the engine is taken out of operation. Residues of old engine oil are  
flushed away in this way and the bearing parts are largely protected against corrosion.  
Preparations for mothballing  
WARNING  
Handling operating materials and supplies  
Swallowing or inhaling vapours of operating materials and supplies or con-  
tact with them may be harmful to health.  
u Do not breathe in these substances and avoid contact with the skin.  
u Ensure proper ventilation.  
u Observe the information in the material safety data sheet for the operat-  
ing materials and supplies.  
u Wear personal protective equipment (PPE) according to the material  
safety data sheet.  
u Comply with local legislation.  
Wear safety goggles.  
Wear safety gloves to protect against chemical hazards.  
Wear a respiratory mask to protect against gases.  
If the acid number (TAN) is greater than 2 mg KOH/g, the following mothballing measures  
are necessary after taking the engine out of operation:  
u Dismantle the turbocharger.  
u The rotor and bearing parts must be dismantled and subsequently refitted by an ABB Tur-  
bocharging Service Station.  
u Clean all parts.

ation for more than 12 months  
u Coat plain surfaces of steel and cast parts with anticorrosive oil.  
u Fit turbocharger completely.  
Rotation of the rotor in the stack draught  
If the rotor turns as a result of the stack draught:  
u Install a blind flange between the outlet flange of the compressor casing and the charge  
air duct.  
10.2  
Taking the engine out of operation for more than  
12 months  
If the engine is taken out of operation, the following variants are possible with regard to the  
turbocharger:  
¡
¡
Turbocharger remains attached to the engine  
The casings of the turbocharger remain attached to the engine, the rotor and bearing  
parts are dismantled by an ABB Turbocharging Service Station and stored separately  
¡
The turbocharger is completely removed, either as a whole unit or in individual parts  
For the measures always necessary for preparing the turbocharger parts for mothballing,  
see section Taking the engine out of operation for up to 12 months, subsection Preparations  
for mothballing.  
If the turbocharger remains attached to the engine, see section Taking the engine out of op-  
eration for up to 12 months, subsection Rotor turning in stack draught.  
If the complete turbocharger is removed or the turbocharger is assembled again from the  
individual parts:  
u Seal all openings of the turbocharger with paraffin paper and wooden lids.  
Only dry rooms with 40 ... 70 % atmospheric humidity, in which no water condensation can  
form, are suitable as storage locations.  
State of the mothballed turbocharger  
u Check the turbocharger parts annually for corrosion.  
u If there are signs of rust: Thoroughly clean parts and renew corrosion protection.
