The operational limits for the turbocharger nBmax, tBmax, nMmax, tMmax, inspection- and replacement intervals for the compon- ents concerned on the rating plate are valid for the operational mode and compressor inlet condition, which has been agreed upon between the engine builder and ABB. Note: Replacement intervals of components depends on the load profi le, turbine inlet temperature, suction air temperature and turbocharger speed. In case the operation conditions differs signifi cantly from what is considered to be normal for the cur- rent application, it is recommended to contact ABB for a re-calculation of replacement intervals. Frequent load alterations, high temperatures and high speed lower the life of components. Unless otherwise agreed, the application limits nMmax, tMmax are valid for the test operation for a limited time.

Preliminary remarks 1 Layout and function 1.2 Page 5 © Copyright 2016 ABB. All rights reserved. September 2016 HZTL2412_EN Revision F Mode of operation The turbocharger is a turbomachine consisting of the following main com- ponents:  Turbine  Compressor These are mounted on a common shaft. Exhaust gases from the diesel or gas engine flow through the turbine cas- ing (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 axi- al thrust bearing (5) is located between the two radial plain bearings. The bearings are connected to a central lubricating oil duct which is sup- plied by the engine's lubricating oil circuit. The oil outlet is always at the lowest point of the bearing casing (4).

Start-up 3 Oil supply 3.1 Page 35 © Copyright 2016 ABB. All rights reserved. September 2016 HZTL2412_EN Revision F Start-up Oil supply 3.1 A carefully designed and installed oil supply, which functions in all possi- ble operational conditions, is an important prerequisite for trouble-free tur- bocharger operation. The turbocharger is normally lubricated with oil from the engine oil circuit. If a separate lubricating system is used, then emergency lubrication is al- so to be provided.  Heed the instructions of the engine builder when selecting the lubricat- ing oil and oil-change intervals. Oil filtration 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 34 µm. This means that contaminants larger than 0.034 mm must be filtered out of the oil with a separation efficiency > 99%.  Fit an accessory filter if engine oil filter is not efficient enough.  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.  Check that oil filters are clean before commissioning. NOTICE Also follow the enginebuilder's instructions regarding filter mesh and separation efficiency. 3 3.1

Maintenance 5 Foreword to Maintenance 5.1 Page 55 © Copyright 2016 ABB. All rights reserved. September 2016 HZTL2412_EN Revision F Maintenance Foreword to Maintenance 5.1 General maintenance work involves regular visual checks and cleaning tasks which are intended to ensure the trouble-free functioning of the tur- bocharger. The maintenance points described here are differentiated as follows:  Cleaning during operation: – Compressor – Turbine and nozzle ring.  Mechanical cleaning of individual components: – Filter silencer – Casings, diffuser, nozzle ring – Cartridge group: Compressor, turbine CAUTION Risk of damage during mechanical cleaning If mechanical cleaning is carried out too often, this can lead to damage and corrosion on the components.  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.  Perform mechanical cleaning, especially of the cartridge group, only once within the service interval. NOTICE Cleaning method To allow you to observe the standard service intervals and to maintain a high turbocharger efficiency, ABB Turbo Systems 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.  Dispose of dirty water and cleaning agents in an environmentally com- patible manner, professionally and in accordance with valid local regu- lations. 5 5.1

Maintenance 5 Cleaning the compressor during operation 5.2 Page 56 © Copyright 2016 ABB. All rights reserved. September 2016 HZTL2412_EN Revision F Cleaning the compressor during operation 5.2 The contamination of the compressor stage (compressor wheel, wall in- sert and diffuser) depends on the degree of purity of the taken-in air. 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. But it never replaces the regular service work where the turbocharger is completely dismantled and the compressor is mechanically cleaned. 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. The interval between periodic cleaning is very dependent on the operating conditions. In general, cleaning should be carried out every 25 ... 100 op- erating hours. Should the specified cleaning intervals prove incompatible with engine operation, please contact ABB Turbo Systems. 5.2 General Cleaning interval

Maintenance 5 Cleaning the compressor during operation 5.2 Page 57 © Copyright 2016 ABB. All rights reserved. September 2016 HZTL2412_EN Revision F Cleaning method Cleaning the compressor while in operation is carried out as wet cleaning. This cleaning method has been tested and approved by ABB Turbo Sys- tems. To clean the compressor stage during operation, water is injected in front of the compressor wheel through an injection pipe fitted in the filter silenc- er or the suction branch. The water does not act as a solvent, but the dirt deposit is removed by the mechanical impact of the droplets. This is a very suitable process, provid- ed 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  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. In the case of sequential charging, care must be taken to ensure that tur- bocharger compressors are cleaned regularly, especially after periods of operation in the lower performance range. Principle of wet cleaning V-engines Sequential charging

NOTICE Whether or not cleaning has been successful can be seen from the charging or flushing pressure and also from the exhaust gas tempera- tures. 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.

Maintenance 5 Turbine cleaning during operation 5.3 Page 60 © Copyright 2016 ABB. All rights reserved. September 2016 HZTL2412_EN Revision F Turbine cleaning during operation 5.3 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 Turbo Systems recommends using fuels with a low ash, sulphur, so- dium and vanadium content. 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 contamination deposits. Experience with turbocharger operation shows that the intervals between overhauls can be extended if cleaning while in operation is carried out pe- riodically. 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 opera- tion 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 mechani- cally 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 op- erating hours. 5.3

September 2016 HZTL2412_EN Revision F NOTICE Cleaning intervals Should the specified cleaning intervals prove incompatible with engine operation, please contact ABB Turbo Systems. Cleaning method Turbine components are cleaned during operation using the wet cleaning processes described in the following. These have been tested and are approved by ABB Turbo Systems. The turbine casing design and the type of turbine casing sealing are deci- sive for the choice of cleaning method. NOTICE Approval by engine manufacturer The prerequisite for wet cleaning is that the engine manufacturer ap- proves the method and his instructions are followed. Wet cleaning methods Process with short water injection time (3 x 30 seconds cleaning) The cleaning process with short water injection time is used for turbo- charger 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 turbo- charger 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. 5.3.1

Maintenance 5 Turbine cleaning during operation 5.3 Page 62 © Copyright 2016 ABB. All rights reserved. September 2016 HZTL2412_EN Revision F 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 Turbo- charger service station. Prerequisites CAUTION Risk of corrosion and deposits Impairment and damage of turbocharger by salt water and cooling wa- ter additives in flow ducts  Don't use salt water for cleaning, but only clean fresh water.  Avoid corrosion on casing inner surfaces.  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 tem- perature after the cylinder. This should be taken into consideration when setting the operating point before cleaning.  Don't exceed maximum temperature in front of turbine when clean- ing. 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 compo- nents and can cause flooding of the turbine.  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 pro- cess is faster and the risk of turbocharger surging is reduced. 5.3.2

September 2016 HZTL2412_EN Revision F Speed measurement system 6.5 Possible causes Elimination No signal or amplitude is poor Fitting error The screw plug for the sensor is fitted with an additional gasket (copper ring). When fitting the speed sensor, this gasket must be removed. If the gasket is fitted by mistake, the distance from the sensor tip to the signal-generating sealing disc increases. As a result, the voltage amplitude of the speed signal decreases, which can cause problems for the evaluation electronics. This problem is eliminated by removing the gasket. Defective sensor Contact an ABB Turbocharging Service Sta- tion Measured speeds too high Contaminated sensor tip The sensor tip is magnetic and can thus at- tract metal particles. As a result, the dis- tance to the signal-generating sealing disc is reduced, which can lead to amplification of the noise component and consequently to faulty triggering. Dismantle the sensor, clean its tip and refit the sensor using the specified tightening torque. Measured speed too low - - Contact an ABB Turbocharging Service Sta- tion Other sources of errors - - If none of the above measures eliminates the malfunction, we recommend that you have the speed measuring system inspected by an ABB Turbocharging Service Station. 6.5
