  1. Summary

  The documentation for this diesel engine type comprises the
  following books andpublications:

  1.1 Operating ManualThis contains information covering engine
  operation, the required operating media(oil, water and fuel), as
  well as a description of the function of specific systems.

  1.2 Maintenance ManualThis contains, in addition to the
  maintenance diagrams, information covering spe-cific dismantling
  and assembly work necessary for engine maintenance.It contains
  furthermore a masses (weight) table of certain individual parts, a
  clear-ance table, a list of rubber / O-rings, tightening values for
  important screwed con-nections and a tools list.

  1.3 Code Book (spare parts catalogue)In this book all parts are
  marked with a code number by which they can be orderedfrom Wrtsil
  Switzerland Ltd or the engine supplier. Such spare parts are to
  beordered exclusively from this book.

  1.4 Documentation for bought-out itemsSeparate publications are
  provided for those items on the engine supplied by out-side
  manufacturers, such as turbocharger, automatic filter, torsional
  vibrationdamper, etc. In most cases these can also be used as a
  spare parts catalogue.

  1.5 Records and drawingsWith the first delivery of the
  documentation, the setting tables, shop trial docu-ments and
  surveyors certificates of the engine concerned as well as
  schematicdiagrams are also supplied.

  2. Structure of manuals

  Generally the manuals have to be regarded as Basic Manuals. They
  describeparticularly the standard engine with all cylinder numbers,
  alternative designexecutions and special equipment.As a rule, in
  the case of alternative design executions the descriptions have
  beendivided in separate groups and clearly designated by the
  respective alternativenames. This allows on one hand to quickly
  find with certainty the respective pas-sages, on the other hand it
  allows the later removal of sheets of not supplied alter-natives
  and special executions.Further indications can be found under
  Explanation on the Use of the OperatingManual 00401.

  3. Repeat-order of technical documentation

  Remark: Corresponding to the continuing development of the
  engines the docu-mentation is continually being updated.This means
  that in a later ordered manual for the same engine, text and
  designa-tions may no longer coincide in every way with the previous
  version (see modifica-tion date on the relevant pages).Not
  withstanding the foregoing, important information and improvements
  arebrought to the customers notice by Service Bulletins so that the
  relevant part ofany development should already be known.When
  ordering documentation at a later stage for engines which have
  alreadybeen in operation since several years, the following details
  are basically required: Engine type, year of manufacture and engine
  manufacturer Name of vessel or site of installation Cylinder or
  engine number Special equipment Language of documentation (German
  or English) Form of documentation (printed Manuals or CD-ROM)

  1. General

  The RTflex engine is a single acting two-stroke diesel engine of
  crossheaddesign with exhaust gas turbocharging and uniflow
  scavenging.

  For direct coupled propeller drive it is reversible. The RTflex
  concept is based on the Wrtsil Common Rail, with full electron-

  ic control of fuel injection and exhaust valve actuation. The
  engine control is devised in such a way that remote controls of
  recom-

  mended manufacturers which correspond to our specifications can
  be builton, because the locations of interfaces are exactly
  defined.

  In case of failure of the remote control the engine can be
  controlled with emer-gency control from the local control
  panel.

  Tie rods bind the bedplate, columns and cylinder jacket
  together. Crankcase and cylinder jacket are separated from each
  other by a partition

  which incorporates the sealing gland boxes for the piston rods.
  The thrust bearing and turning gear are situated at the engine
  driving end. The exhaust valve actuation and the electronic
  injection are controlled by the

  engine control system WECS9520. Lubricating oil, cooling water,
  fuel feed and booster pumps as well as air com-

  pressors are parts of the engine room installation (ancillary
  systems).

  2. Systems

  The exhaust valves are opened hydraulically by the servo oil
  system andclosed pneumatically. The oil supply is ensured from the
  bearing oil systemthrough a fine filter. Servo oil pumps in the
  servo pump unit provides the servooil rail with the required
  pressure via three rising pipes.

  The pistons are cooled by bearing oil.

  Fuel pumps in the fuel pump unit deliver fuel under high
  pressure into the fuelrail via rising pipes and subsequently
  through the injection control units toeach injection valves.

  The injection control units are activated via the servo oil
  system.

  The cylinders and cylinder covers are fresh water cooled. For
  cooling the scavenge air a single-stage cooler is used with central
  fresh

  water cooling (closed circuit).

  The engine is started by compressed air entering into the
  cylinders via startingvalves, controlled by the WECS9520.

  GeneralBrief Description of the Engine

• Operation00501/A1 RT-flex82C

  Wrtsil Switzerland Ltd 2/ 2

  The exhaust gases flow from the cylinders through the exhaust
  valves into anexhaust gas manifold.

  The turbochargers work on the constant pressure charging
  principle. The scavenge air delivered by the turbochargers flows
  through air cooler and

  water separator into the air receiver.It enters the cylinders
  via air flaps through the scavenge ports when the pis-tons are
  nearly at their BDC.

  At low loads independently driven auxiliary blowers supply
  additional air to thescavenging air space.

  First Stroke: (Compression) Piston in BDC (Bottom Dead Centre).
  Scavenge ports and exhaust valve open. Scavenge air flows into the
  cylinder and presses the exhaust gases through

  the exhaust valve into the exhaust gas manifold and from there
  to the turbo-charger.

  Piston moves upwards.Point ES:

  Scavenge ports are being closed by the piston.Point AS:

  Exhaust valve shuts, compression begins.

  Second Stroke: (Ignition Combustion Expansion Exhaustion
  Scavenging) At around the TDC (Top Dead Centre) fuel is injected
  into the cylinder. The fuel ignites in the compressed, heated air =
  ignition. With ignition com-

  bustion begins. The gases expand and press the piston downwards
  (working stroke).

  Point AO: The exhaust valve opens, exhaust gases flow out of the
  cylinder into the ex-

  haust gas manifold and from there to the turbocharger.Point
  EO:

  Scavenge ports are being uncovered by the downward moving
  piston. Scavenge air flows into the cylinder and presses the
  exhaust gases out

  through the exhaust valve into the exhaust gas manifold and from
  there to theturbocharger.

  GeneralWorking Principle of the Two-stroke Diesel Engine

• Operation 00701/A1RT-flex82C

  Wrtsil Switzerland Ltd 1/ 2

  1. General

  There is a defined relationship between the propeller speed and
  the absorbedpower in ships equipped with fixed pitch
  propellers.With a given propeller this relationship mainly depends
  on its rotational speed.The following formula provides us with an
  approximation which is adequate for thegeneral consideration of
  conventional vessels:

  =

  P1P2

  n1

  n2

  3

  Its graph is called the propeller characteristic.

  If an engine is in good condition and properly supplied with air
  (i.e. turbocharger(s)in good order and the air and exhaust lines
  have low additional resistance) and thefuel injection quantity is
  properly adjusted (see setting table), the mean effectivepressure
  developed under service condition according to the specific reading
  ofthe load indication corresponds approximately with the mean
  effective pressureestablished for this particular position on the
  test bed.

  In the diagram, the propeller characteristic line through the
  point of CMCR (Con-tract Maximum Continuous Rating), i.e. nominal
  power at nominal engine speed(100% power at 100% engine speed) is
  called the nominal propeller characteristic.Engines which are to be
  employed for the propulsion of vessels with fixed propel-lers are
  loaded on the test bed according to this propeller characteristic.
  However,the power requirement of a new ship with a smooth and clean
  hull should be lessand correspond to the range D.

  With increasing resistance, changes in wake flow conditions, due
  to marine growthand ageing of the vessels hull, a rough or
  mechanically damaged propeller, unfa-vourable sea and weather
  conditions or operation in shallow water, the propellerwill require
  a higher torque to maintain its speed than it did at the time of
  sea trial.The mean effective pressure of the engine (and thus the
  fuel injection quantity) willincrease accordingly. In such a case,
  the operating point will then be located to theleft of the original
  propeller curve which was established during sea trials.

  Although cleaning and re-painting will help to reduce the
  increased resistance ofthe ships hull, the original condition can
  no longer be attained.

  Whereas the thermal loading of an engine depends chiefly on the
  mean effectivepressure, the position of the operating point is also
  important; the farther left it issituated from the propeller curve
  in the diagram (page 2), the poorer the air supplyto the engine and
  the more unfavourable the engines operating conditions will
  be-come.

  In order to attain optimum working conditions, the operating
  point of the engine forcontinuous service should lie in range A on
  the right side of the nominal propellercharacteristic.

  Explanations:CMCR = Contract Maximum Continuous RatingP = Powern
  = speedmep = mean effective pressure

  A The portion on the right of the nominal propeller
  characteristic is the ser-vice range without continuous operating
  restrictions related to the se-lected CMCR point.The portion on the
  left of the nominal propeller characteristic is the servicerange
  for transient operating conditions (acceleration) and should
  beavoided for continuous operation.

  A Maximum permissible engine power 40% CMCR from approx. 50% up
  to67% of CMCR speed.

  B Service range with operational time limit, follows a
  characteristic:P n 2.45.This characteristic originates from the
  reference point 95% CMCR powerand 95% CMCR speed. With longer
  operating time in this range, thermaloverloading and possible
  resulting engine damage may be expected.

  C Service range with overspeed of 104 to 108% of CMCR speed,
  only per-missible during sea trials to demonstrate the CMCR power
  in presence ofauthorized representatives of engine builder.
  However, the specified tor-sional vibration limits must not be
  exceeded.

  D Recommended layout range for fixed pitch propeller, valid for
  the maxi-mum draught, clean hull under contractual weather and sea
  conditions.

  E Overload range permissible only for maximum one hour during
  seatrialsin presence of authorized representatives of engine
  builder.

  1. Starting position

  It is assumed that: all components on which overhaul work was
  carried out have previously been

  correctly re-assembled and fitted and checked as to their
  perfect function. all devices and tools which were used have been
  removed from the engine

  and that no cleaning rags or other items have been left behind.
  The setting of the fuel pumps and the connection of the actuators
  with the

  regulating linkage are in order.Attention! Up to point where the
  venting valves 2.21 and 2.27 must be closed, theshut-off valve for
  starting air 2.03 remains in position CLOSED (closed by hand),the
  venting valve 2.21, and the venting valve 2.27 in the starting air
  main must beopen (see Control Diagram 40032).

  2. Checks and preparations

  Check the fluid levels of all the tanks in the engine systems
  (including the leak-age drain tanks).

  Check that all the shut-offs for the engine cooling water and
  lubricating oil sys-tems are in the correct position.

  Check that the lubricating device (tool 94844 provided for
  additional lubrica-tion of the fuel pump drive during overhaul
  works) is removed and the oil pipeis properly closed by means of
  the blank flange (see Maintenance Manual55814).

  Open the air supply from the shipboard system to the control air
  supply A . Open the shut-off cock at connection A1 and put air
  spring venting 4.08 to

  operating position (see Control Air Supply 46051). Preheat the
  lubricating oil to about 35 C (via separating circuit or heating in
  oil

  drain tank). Preheat the cylinder cooling water to min. 60 C.
  Switch on the engine and remote control system WHENS9520.

  Switch on all breakers in the power supply box E85. Check that
  both green indication LETS light up on all FCC20 modules.

  The FCC20 modules are able to function if no red LETS light up
  after thecountdown process.

  Prepare the servo oil system (see 01301). Start up the pumps for
  cylinder cooling water, bearing oil and set the pres-

  sures to their normal values (see Operating Data Sheet 02501).
  Switch on control box for automatic filter (see documentation of
  the automatic

  filter manufacturer). Switch on main switch of the servo oil
  service pumps. Prepare the cylinder lubricating system (see 01401).
  Prepare the fuel oil system (see 01201). Ensure that all systems
  are correctly vented. After ensuring air spring supply, check
  whether all exhaust valves are closed.

  Preparation before Taking into ServicePreparations before
  Starting after a Short Shut-down (One or More Days)

  Open and shut each exhaust valve 4.01 few times manually in
  remote controlin order to ensure thorough venting of the hydraulic
  actuators of the exhaustvalves (user parameter, function Ex. A/M
  Mc).

  Remark: The engine can not be started if the exhaust valves are
  not fully closed. Open each cylinder covers indicator valve. With
  the aid of the turning gear,

  turn the engine through at least one full revolution to check
  that all the runninggears are in order. Neither water, oil nor fuel
  may spray out of the indicatorvalves. If so, depending on the
  liquid, check cylinder liner, cylinder cover, pis-ton or injection
  valves.With this the cylinder lubrication must be switched on.

  Shut indicator valves. Check to ensure that all the crankcase
  doors are locked with all the clamps. Check that the fuel pump
  regulating linkage moves freely. Check the pressure in the starting
  air bottles and open their drains until any

  condensate has been drained. Open the drain and test valve 2.06
  until no more water comes out. Close venting valves 2.21 and 2.27
  and open the main shut-off valves on the

  starting air bottles 9.01. Bring the shut-off valve for starting
  air 2.03 to position AUTOMAT. Open the shut-off cock at connection
  A2 (see Control Air Supply 46051). The pressure gauges on the
  instrument panel must now show starting air and

  control air pressure. A pressure must also be indicated on the
  pressure gauges for the control air

  supply.The different circuits are: Air spring air Control air
  Air supply from the board system and back-up supply from the
  starting air sys-

  tem via the pressure reducing valve 19HA.Required pressures see
  Operating Data Sheet 02501). Set the switches on the control panels
  for the auxiliary blowers to AUTOMAT. Switch off the servo oil
  service pump. Disengage the turning gear and secure the lever. Open
  the test valve 2.06 of the shut-off valve for starting air 2.03 for
  a short

  time and listen if the valve opens (can be heard distinctly).
  Close the test valveagain.

  Press SLOW TURNING button in WHENS9520 manual control panel on

• Operation 01201/A1RT-flex82C

  Wrtsil Switzerland Ltd 1/ 2

  1. For diesel oil operation

  (see 07201 Layout of the fuel oil system) Set three-way valve 21
  in the suction line of low pressure feed pump 23 so that

  diesel oil flows from daily tank 3 to the pump and to mixing
  unit 24. Check to ensure that the shut-off valves before and after
  engine are open. Start up pumps 23 and 25. Drain daily tanks and
  mixing unit. Set pressure in fuel oil system using pressure
  regulating valve 31. When run-

  ning with diesel oil (and low fuel temperature) a slight
  over-pressure is suffi-cient. If later a change-over to heavy fuel
  oil is required, setting of normal pres-sure is recommended from
  the beginning.

  Set fuel oil pressure at fuel pump inlet using pressure
  retaining valve 31a(3.53) (pressure difference before/after
  pressure retaining valve see Operat-ing Data Sheet 02501).

  2. For heavy fuel oil operation

  (see 07201 Layout of the fuel oil system)Remark: The fuel oil
  system is not ready for service until the heavy fuel oil beforethe
  fuel pumps has reached the required temperature (see
  Viscosity-TemperatureDiagram 02702).The high pressure circuit on
  the engine must be preheated for at least four to sixhours after a
  prolonged shut-down period (more than 24 hours).Before that, the
  engine may not be started on heavy fuel oil! Turn on the heating
  for heavy fuel oil daily tank 2, mixing unit 24, end-heater

  26 and filter 27.

  Turn on the heating for the fuel oil system on the engine (fuel
  rail 13 (3.05),rising pipes 8 (3.29) and the fuel leakage system
  (see 80191).

  Remark: Check the steam pipings for tightness; any detected
  leakages must beeliminated before the first commissioning or after
  maintenance works on the fueloil system.

  Set three-way valve 21 in the suction line of low pressure feed
  pump 23 so thatheavy fuel oil flows from daily tank 2 to pump 23
  and to mixing unit 24.

  Drain settling, daily tanks and mixing unit. Check to ensure
  that the shut-off valves before and after engine are open. Start up
  pumps 23 and 25. Heat up the heavy fuel oil. This is necessary to
  bring it to the required viscosity

  (see Changing Over from Diesel Oil to Heavy Fuel Oil 02701). Set
  pressure in fuel oil system using pressure regulating valve 31. Set
  fuel oil pressure at fuel pump inlet using pressure retaining valve
  31a

  (3.53) (pressure difference before/after pressure retaining
  valve see Operat-ing Data Sheet 02501).

  is closed and tightened with a torque of 200 Nm.

  4. Venting and leak test of fuel oil system on engine

  (see 07201 Layout of the fuel oil system (items in parentheses)
  and Fuel OilSystem 80191)

  Venting:The fuel oil system can be vented manually as follows:
  Engine control system WECS9520 is switched on. Start low pressure
  feed pump (23) and booster pump (25). When starting booster pump
  (25) fuel oil circulates through fuel pumps 3

  (3.14) and fuel rail 13 (3.05) is filled via rising pipes 8
  (3.29). By means of hand lever on emergency stop valve 26 (fuel
  shut-down pilot

  valve 3.08) the fuel rail can be vented via fuel pressure
  control valve 25 (3.06).Leak test:

  To carry out a leak test, the high pressure circuit must be kept
  under pressure bymeans of servo oil service pump (4.88). Remove
  plug 32 (3.39) and the plug on stop valve (3.40) and connect
  tool

  94583 (pipe) between fuel rail 13 (3.05) and servo oil rail
  (4.11) and open stopvalve (3.40).

  Switch on bearing oil pump and servo oil service pump (4.88).
  The pressure (70100 bar) can be read off on pressure gauge of the
  servo oil

  service pump. Carry out leak test. Close stop valve (3.40).
  Remove tool 94583 (pipe). Apply Never-Seez NSBT-8 to the thread and
  seat-

  ing surface of plug 32 (3.39) and tighten it with a torque of

  1. General

  The following groups concern operation of the engine under
  normal conditions.By this we understand that, e.g. all cylinders
  are working. During manoeuvring,however, not only is the usually
  normal control of the engine from the control room(or bridge)
  mentioned, but also the possibility of operation from the local
  manoeu-vring stand.For operation under abnormal conditions, see
  05001.Operation in the following sense concerns the complete
  operation of the enginefrom the first start at casting off until
  the final manoeuvre when tying up.The engine is designed and so
  equipped that it can also run pier-to-pier on heavyfuel oil, i.e.
  without having to change over to diesel oil.Fuel also circulates
  through the fuel pumps when the engine is at a standstill aslong as
  the booster pump is running. Preconditions are that the
  installation too islaid out to suit, the heavy fuel oil has been
  correctly treated and it is kept at thecorrect temperature during
  the whole period in service, including manoeuvring andStand-by.

  Operation under Normal ConditionsSummary

  2008

• Operation 02101/A1RT-flex82C

  Wrtsil Switzerland Ltd 1/ 3

  1. General

  A well maintained engine is a pre-requisite for a troublefree
  and safe operation.The below mentioned points should always be a
  guide to the maintenance staff.

  2. Illumination

  Besides a permanent good illumination hand lamps should be ready
  at hand in var-ious locations of the engine room.

  3. Cleanliness

  The engine room as well as the engine itself should always be
  kept as clean aspossible. Special care must be taken to keep the
  WECS electronic control boxesclean and dry on the rail unit. Any
  leakages should be attended to as soon as pos-sible. Dust, sand and
  chemical vapors must be prevented from entering the engineroom.

  4. Warning

  Opening valves and other shut-off devices may allow hot fluids
  or gases to escape.Therefore open slowly and watch in which
  direction the medium escapes.Avoid injury.When removing valves from
  the cylinder cover, avoid that oils or fuels drip onto thehot
  piston which could cause an explosion. When disassembling parts of
  the en-gine without suitable tools and/or the required care,
  prestressed springs can ex-pand suddenly and cause injury. Pay
  attention to the maintenance instructions ofthe corresponding
  parts.

  5. Fire

  Attention! Special attention has to be paid to the rules of fire
  fighting.Welding work and activities which cause sparks must not be
  carried out in theengine room before ensuring that no explosive
  gases, vapors or inflammable fluidsare present. If spark generating
  work must be performed in the engine room makesure that fire
  extinguishing equipment is readily at hand to fight a fire locally.
  Com-ponents such as turbocharger silencer and WECS electronic
  control boxes mustbe protected by suitable covering. When casings
  and covers are removed beforethe engine has cooled down, the risk
  of fire or explosions is increased. Thereforekeep the engine closed
  until it has cooled down.Care must also be taken when paints or
  easily inflammable solvents are used inthe engine room.Insulation
  material saturated with oil or fuel (due to leakages) is also
  easily ignitedand must therefore be replaced.Cleanliness in the
  whole engine room, also below the floor plates, reduces the
  pos-sibility of a fire and the risk of its spreading.For your
  personal safety make absolutely sure that in case of a fire alarm
  no fireextinguishing gases can be automatically released when
  people are in the engineroom. Emergency escapes are to be marked
  and personnel is to be instructed ofwhat to do in the case of
  fire.

  Wrtsil Switzerland Ltd 2/ 3

  6. Tools

  Hand tools should be placed at easily accessible locations and
  clearly arranged.Special tools and devices shall be placed in the
  engine room in the vicinity of theirusual application in such a way
  that they can be used without hindrances.They must be fastened and
  protected against rust.

  7. Spare parts

  Large spares are to be stored as near as possible to their
  probable place of fitting,well braced and secured and within the
  reach of the engine room crane. All thespare parts must be well
  protected against corrosion, but with a compound requir-ing little
  effort for removal. They must also be protected against mechanical
  dam-age. The anti-corrosion agent has to be checked periodically
  and renewed if nec-essary.Spare parts removed from the store must
  be replaced as soon as possible.

  8. Opening the crankcase doors

  If the engine has to be shut-down due to suspected overheated
  parts of the run-ning gear or bearings, at least 20 minutes must
  elapse before the crankcasedoors are unfastened and removed in
  order to avoid the danger of an explosion.

  9. Temperature sensing

  When commissioning an engine after an overhaul of its running
  gear a check mustbe made to find out whether any areas are
  heating-up abnormally. This checkshould be made after 10 minutes
  operation and repeated after about one hour. Fol-lowing this, the
  checking should again be made after a short full load run.Danger of
  burning! When trying to touch the hot parts it is necessary to pay
  atten-tion to avoid injury.

  10. Entering the crankcase, cylinder, exhaust piping or scavenge
  air receiver

  Before entering the spaces of the above parts make sure that:
  starting air to the engine is blocked off and venting valves 2.21
  and 2.27 (see

  Control Diagram 40032) are open. turning gear is engaged (see
  Maintenance Manual 00111 Precautionary

  measures before beginning of maintenance work).Attention! On
  ships, please consider that water currents induced by other
  shipscan cause the propeller and the engine with it to rotate. By
  engaging the turninggear this rotation can be avoided.

  11. Entering the engine after the use of CO2

  Where CO2 has been used to smother a fire within the engine, the
  relevant spacesmust be thoroughly ventilated before entering (risk
  of suffocation).

• Operation 02101/A1RT-flex82C

  Wrtsil Switzerland Ltd 3/ 3

  12. Closing up of crankcase doors

  The engine may not be put into service until all the crankcase
  doors are closedby all the locking latches. This also applies even
  if only a short run is to be made,e.g. running in replaced
  bearings, etc.

  13. Turning gear

  When using the turning gear, the indicator valves in the
  cylinder covers must beopened. In case the air spring system is not
  under pressure, the indicator valvesmay remain closed. If possible,
  the lubricating oil pump should also be running.However, the oil
  pressure cannot fully build up when the exhaust valves are
  open.Attention! Check carefully, that no personnel as well as
  components (tools,devices) are situated in the danger area
  (crankcase, piston underside, propellershaft etc.).Also bear in
  mind that the coupled propeller turns too (danger in
  surroundings).Remark: If the engine is standing still for overhaul,
  the turning gear must be en-gaged in order to prevent the engine to
  be turned due to outside influence.If the engine must be ready for
  manoeuvres the turning gear must not be en-gaged.Before starting
  the engine, make sure that the turning gear is disengaged andthe
  lever secured otherwise blocking valve 2.13 (see Control Diagram
  40032)hinders the start of the engine.

  14. Measuring and indicating instruments

  Calibrate gauge tools before using and at periodical
  intervals.

  15. Frost hazard

  If there is a possibility that the temperature falls below the
  freezing point with theengine out of service, measures must be
  taken that the water in the engine, in thepumps, coolers and piping
  system cannot freeze. (Draining the systems or heat-ing the engine
  room).

  Remark: Further instructions concerning general guidelines for
  maintenance seeMaintenance Manual 00111 and 00121.

  Safety Precautions and Warnings (General Information)

• Operation 02201/A1RT-flex82C

  Wrtsil Switzerland Ltd 1/ 1

  1. General

  To ascertain that the running gear turns freely, we recommend,
  provided no morefar reaching specifications have been made by the
  classification society, to rotatethe crankshaft before start-up by
  at least one full turn. This does not apply if theengine has only
  been standing still during a manoeuvring interval.

  2. Turn by the turning gear

  With the turning gear the crankshaft can be rotated especially
  slowly at about onerevolution per 10 minutes. The rotation of the
  crankshaft as well as the direction ofrotation can be noted on the
  pointer by the flywheel.

  3. SLOW TURNING with starting air

  The running gear can be turned at approx. 510 rpm by releasing a
  controlledamount of starting air.In the engine control system
  WECS9520 the command SLOW TURNING is pro-vided for this operation.
  Depending on the active control stand it is initiated: by remote
  control at ECR manual control panel in the control room at local
  control panel (see 46181 WECS9520 Manual control panel).

  3.1 ConditionsBeforehand the following conditions must be
  fulfilled: Turning gear disengaged. WECS9520 engine control system
  switched on. Oil pumps operating (bearing oil and crosshead oil).
  Corresponding control stand activated. Indicator valves closed.
  Handwheel 2.10 on shut-off valve for starting air 2.03 in position
  AUTOMAT. Shut-off valves on the starting air bottles open. Air
  pressure for air spring correctly set (see Operating Data Sheet
  02501). For slow turning the cylinder lubrication must be
  switched-on.

  3.2 FunctionThe procedure is similar to starting of the engine.
  The following designation num-bers refer to the Control Diagram
  40032. The shut-off valve for starting air 2.03 is opened by the
  control valve 2.05 and

  starting air reaches the starting air valves 2.07 in the
  cylinder covers. By FCM20 modules the 3/2-way solenoid valves
  before the starting valves

  are controlled in such a way that the starting valves are opened
  and shut forshort intervals only.

  The slow turning speed of the engine can be optimized in the
  remote controlby varying the timing (open/close) of the starting
  valves.

  Operation under Normal ConditionsStarting

  2008

• Operation 02401/A1RT-flex82C

  Wrtsil Switzerland Ltd 1/ 3

  1. General

  The most favourable operational results are generally achieved
  by running the en-gine at constant power. When the engine load
  and/or speed have to be altered onoperational grounds, this should
  be done slowly, apart from exceptional circum-stances.

  2. Checks and precautions

  During normal running, regular checks have to be made and
  precautions takenwhich contribute to trouble-free operation. The
  most important of these are:

  Regular checks of pressures and temperatures. The limits must be
  adheredto (see Operating Data Sheet 02501).

  The values read off the instruments compared with those given in
  the accep-tance records and taking into account engine speed and/or
  engine power,provide an excellent yardstick for the engine
  performance.Any deviation must be investigated. The fault can lie
  with either the engine,the installation or also with the
  instruments. Where no risk exists, suspect in-struments can be
  exchanged with similar ones. Compare temperatures byfeeling the
  pipes. To make the above mentioned evaluation, among the es-sential
  readings are: fuel injection quantity, fuel rail and servo oil rail
  pressure,engine speed, turbocharger speed, scavenge air pressure,
  exhaust gas tem-perature before the turbine. A valuable criterion
  is also the daily fuel consump-tion, taking the lower calorific
  value into consideration.

  Check all shut-off valves in the cooling and lubricating system
  for correct posi-tion.The shut-offs for the cooling inlets and
  outlets on the engine must always befully open in service. They
  serve only to cut off individual cylinders from thecooling water
  system during overhauls.

  When abnormally high or low temperatures are detected at a water
  outlet thetemperature must be brought to the prescribed normal
  value very gradually.Abrupt temperature changes may cause damage
  (see also Cylinder Liner21241 and Cooling Water System 80171).

  The maximum permissible exhaust temperature at turbine inlet
  must not beexceeded (see Operating Data Sheet 02501). The indicated
  exhaust gastemperatures at cylinder outlet are to be compared with
  the correspondingvalues of the acceptance records. Should greater
  differences between indi-vidual cylinders be noted, the cause has
  to be investigated.

  Check outlet of exhaust gases by observing their colours at the
  funnel. Nodark smoke should escape.

  Maintain the correct scavenge air temperature after the air
  cooler with the nor-mal water flow (see Operating Data Sheet
  02501). In principle, a higherscavenge air temperature will result
  in poorer filling of the cylinder which inreturn will result in a
  higher fuel consumption and higher exhaust gas temper-atures.

  Check the scavenge air pressure drop through the air cooler.
  Excessive re-sistance will lead to a lack of air to the engine.

  The fuel oil has to be carefully cleaned before being used.
  Refer to recom-mendations in 07201Fuel treatment and the separator
  manufacturers in-structions. Open the drain cocks of all fuel tanks
  and fuel oil filters regularly fora short period to drain off any
  water or sludge which may still have collectedthere. Maintain the
  correct fuel oil pressure after low pressure feed pump andthe inlet
  to the mixing unit (see Operating Data Sheet 02501 and 07201Layout
  of the fuel oil system). Adjust the pressure at fuel pump inlet
  with thepressure retaining valve in the fuel oil return pipe so
  that the fuel oil circulateswithin the low pressure circuit of the
  engine at the normal delivery capacity ofthe booster pump.

  The heavy fuel oil has to be sufficiently heated to ensure that
  its viscosity be-fore inlet to the fuel pumps lies within the
  prescribed limits (see Viscosity-Tem-perature Diagram 02702).

  Now and then determine the cylinder lubricating oil consumption.
  For normalconsumption and how to calculate it, see Measurement of
  the Cylinder Lubri-cating Oil Consumption 72182. Extended service
  experience will determinethe optimum cylinder lubricating oil
  consumption. Avoid over-lubrication.

  The cooling water pumps should be run at their normal operating
  point, i.e. theactual delivery head corresponds with the designed
  value. Thereby the de-signed delivery rate is obtained and the
  temperature difference between inletand outlet will approximately
  correspond with the desired value (see Operat-ing Data Sheet
  02501). Should it be considerably higher, the pump con-cerned must
  be put in order at the next opportunity.

  Should correct setting of the pressure head of the cylinder
  cooling water pumprequire throttling of the flow, this may only be
  done in the engine outlet man-ifold. The pressure at the suction
  side of the pump must be positive in order toprevent any air being
  drawn in through its stuffing box.

  The vents at the uppermost points of the cooling water spaces
  must beconstantly kept open to permit air to escape.

  Check the level in all water and oil tanks, as well as all the
  drainage tanks ofthe leakage piping. Investigate any abnormal
  changes.

  Observe the cooling water. The cause of any contamination or
  oiliness has tobe investigated and the fault rectified.

  Check periodically the water flow at the sight glasses of
  condensate collectors20 and 20a. The butterfly valves 26 and 26a
  must always be open during op-eration (see Drainage System and
  Wash-water Piping System 83451).

  Check the pressure drop across the oil filters. Clean them if
  necessary. Check periodically the differential pressure through the
  automatic filter and

  the flushing process. Bearings which have been overhauled or
  replaced must be given special

  attention for some time after being put into service. Observe
  the precautionsfor preventing crankcase explosions (see 04601).

  Always keep the covers of the rail unit closed with the engine
  in service. Listening to the noise of the engine may reveal any
  irregularities.

  Hand drawn indicator diagrams provide information on the
  combustion pro-cess and pressures within the cylinder (see
  Indicator Diagrams 04201).When the quality of the fuel used changes
  (diesel oil, heavy fuel oil from vari-ous bunkerings), the maximum
  pressure in the cylinder at service power mustbe determined at the
  earliest opportunity and compared with the pressuremeasured during
  the corresponding shop trial (speed, power).In case considerable
  firing pressure differences are detected, i.e. too high ortoo low,
  they must be adjusted by the electronic FQS in WECS9520
  controlsystem.

  Centrifuge the lubricating oil. Samples should be taken at
  regular intervalsand compared with the values given in Lubricating
  Oils 07501.

  Check the dirty oil drain pipes from the piston underside for
  free passage. Anobstruction can be detected by touching the
  individual drain pipes with thehand (temperature difference). If
  one has only surrounding temperature, theline must have been
  blocked by carbon deposits and needs to be cleaned assoon as
  possible.

  Check periodically the lubricating and fuel oil systems for
  leakages (see80161 Servo oil leakage system and 80191 Fuel leakage
  system). Leak-ages can be localized in the rail unit by opening the
  corresponding hinged cov-ers and casings. Ascertained leakages must
  be remedied at the next opportu-nity.
