The process isended when the first piston ring forms a perfectseal towards the combustion chamber, i.e. thefirst piston ring exhibits an even running surfacearound its entire circumference. lf the engine issubjected to a higher load before this occurs,the hot exhaust gases will pass between the pis-ton rings and the cylinder liner running surface.The film of oil will be destroyed at these loca-tions. The consequence will be material destruc-tion (e.g. burn marksl on the running surfaces ofthe rings and the cylinder liner and increasedwear and high oil consumption during subse-quent operation.The duration of the running-in period is influ-enced by a number of factors, including the con-dition of the surface of piston rings and thecylinder liner, the quality of the fuel and lube oiland the loading and speed of the engine. Therunning-in periods shown in "Figure 2-34 Stand-ard running-in programme for marine auxiliaryengines (constant speedl of the 32/40, 32/44CRengine types, page 2-109", and "Figure 2-35Standard running-in programme for marine aux-iliary engines (constant speedl of the 40/54, 48/60B, 48/60CR, 58/64 engine types, page2-110", respectively, are there for guidance only.Operating mediaFuelFor the engine running-in process can be usedDiesel oil or gas oil. The fuel used must satisfythe quality requirements (see "Chapter 3 Qualityrequirements of operating supplies, page 3-1"land be appropriate for the fuel system layout. Lubricating oilThe lubricating oil to be used while running in theengine must satisfy the quality requirements(see "Chapter 3 Quality requirements of operat-ing supplies, page 3-1"l relating to the relevantfuel quality.Caution!The lube oil system is to be rinsed out before fill-ing it for the first time (see MAN Diesel WorkCard 000.03l.Running-in the engineCylinder lubricationDuring the entire running-in process, the cylin-der lubrication is to be switched to the Run-ning-in" mode. This is done at the controlcabinet and/or the operator's panel and causesthe cylinder lubrication to be activated over theentire load range already when the engine isstarted. The increased oil supply has a favoura-ble effect on the running-in of the piston ringsand pistons. After completion of the running-inprocess, the cylinder lubrication is to beswitched back to Normal Mode".ChecksDuring running-in, the bearing temperature andcrankcase are to be checked for the first time after 10 minutes of operation Page 2 - 108 Status 10/20080201-0303MA.fmDiesel engine and operation2.2.4 Diesel electric operationat minimum speed, again after operational output levels havebeen reached. The bearing temperatures (camshaft bearings,big-end and main bearingsl are to be measuredand compared with those of the neighbouringbearings. For this purpose, an electric tracer-type thermometer can be used as measuringdevice.At 85% load and on reaching operational outputlevels, the operating data (firing pressures, ex-haust gas temperatures, charge air pressure,etc.l are to be checked and compared with theacceptance record. Standard running-in programmeln the case of engines driving generators, theengine speed is, within the specified period, atfirst increased up to the normal speed beforeload is applied. During the entire running-in pe-riod, the engine output is to remain within theoutput range that has been marked in "Figure 2-34 Standard running-in programme for marineauxiliary engines (constant speedl of the 32/40,32/44CR engine types, page 2-109" and "Figure2-35 Standard running-in programme for marineauxiliary engines (constant speedl of the 40/54,48/60B, 48/60CR, 58/64 engine types, page2-110", resp. Critical speed ranges are to beavoided.Running-in during commissioning at siteFour-stroke engines are, with a few exceptions,always subject to a test run in the manufactur-er's works, so that the engine has been run in, asa rule. Nevertheless, repeated running-in is re-quired after assembly at the final place of instal-lation if pistons or bearings were removed forinspection after the test run or if the engine waspartly or completely disassembled for transpor-tation.Running-in after installation of new running gear componentsln case cylinder liners, pistons and/or pistonrings are replaced on the occasion of overhaulwork, the engine has to be run in again. Run-ning-in is also required if the rings have been re-placed on one piston only. Running-in is to becarried out according to "Figure 2-34 Standardrunning-in programme for marine auxiliary en-gines (constant speedl of the 32/40, 32/44CRengine types, page 2-109" and "Figure 2-35Standard running-in programme for marine aux-iliary engines (constant speedl of the 40/54, 48/60B, 48/60CR, 58/64 engine types, page2-110", and/or the pertinent explanations.The cylinder liner requires rehoning according toMAN Diesel Work Card 050.05 unless it is re-placed. A portable honing device can be ob-tained from one of our service bases.Running-in after refitting used or installing new bearing shells (main bearing, big-end and piston pin bearingsllf used bearing shells were refitted or new bear-ing shells installed, the respective bearings willhave to be run in. The running-in period shouldbe 3 to 5 hours, applying load in stages.

Combustion residues from the fuel and lu-bricating oil may deposit on the top-land ring ofthe piston, in the ring grooves and possibly alsoin the inlet ducts. Besides, the charge air and ex-haust piping, the charge air cooler, the turbo-charger and the exhaust gas boiler may becomeoily.Status 10/2008 Page 2 - 1090201-0303MA.fmDiesel engine and operation2.2.4 Diesel electric operationAs also the piston rings will have adapted them-selves to the cylinder liner according to theloads they have been subjected to, acceleratingthe engine too quickly will result in increasedwear and possibly cause other types of enginedamage (piston ring blow-by, piston seizurel.After prolonged low-load operation (500 opera-tion hoursl, the engine should therefore be run inagain, starting from the output level, at which ithas been operated, in accordance with "Figure2-34 Standard running-in programme for marineauxiliary engines (constant speedl of the 32/40,32/44CR engine types, page 2-109" and "Figure2-35 Standard running-in programme for marineauxiliary engines (constant speedl of the 40/54,48/60B, 48/60CR, 58/64 engine types, page2-110".

This ensures that the enginescan be operated in the maximum output rangeand, in case one unit fails, the propulsive outputis reduced or unimportant users are switched offby the power management in order to avoid anelectric black-out due to underfrequency.lt is up to the ships operator to decide, whichconsumers are disconnected from the supplyunder what operating conditions or which ofthem are given priority. With regard to contamination and soot behav-iour during low-load operation, the chosen loadreserve achieved by the number of engines run-ning in the system should not be too high (i.e.several engines running on low loadl. Regarding the optimum operating range and thepermissible part loads, the information providedin "Chapter 2.2.2 Part-load operation, page2-69" are to be observed.Load application in case one engine failsln case one engine fails while running at sea, itsoutput has to be made up for by the engines re-maining in the system and/or the loading has tobe decreased by reducing the propulsive outputand/or by switching off electric consumers.The immediate load transfer to one engine doesnot always correspond with the load reservesthis particular engine still has available. This de-pends on the base load that is being run at in therespective moment. The permissible load applications for such acase can be derived from the following "Figure2-39 Load application depending on base load,page 2-115".

The sys-tem is designed to ensure that the functions areachieved in accordance with the classificationsocieties' requirements for marine propulsionengines.The safety system directly monitors emergencyshut-down, speed control and the auxiliary drivecabinet.ln addition to the provisions made to permit theinternal initiation of demands, binary and ana-logue channels have been provided for the initi-ation of safety functions by external systems: Emergency engine stop by the generator pro-tection Emergency engine stop by the load manage-ment Emergency engine stop by the heat recoveryboiler Emergency stop by manual emergency shut-down device Monitoring of the generator windings Emergency stop by gear box parameters.Load reductionLoad reduction has to be realised by the propul-sion control system. Load reductions are onlyimplemented after preceding alarm initiation bythe subsystem alarm pre-processing, and arerequested by the safety system. Emergency stoplf an emergency stop is triggered by the safetysystem, the emergency stop signal has an im-mediate effect on the emergency shut-down de-vice and the speed control. At the same time theemergency stop is triggered, SaCoS issues asignal for zero pitch.OverrideSafety actions can be suppressed by the over-ride function for various parameters. The over-ride has to be selected before a safety action isactuated. The scope of parameters prepared foroverride are different and depend to the chosenclassification society.2.3.3.2 Alarm pre-processingThe subsystem alarm pre-processing works in-dependently from the safety system. lt monitorsDiesel engine and operation2.3.3 SaCoS Page 2 - 124 Status 01/20060203-0104MA.fmall operating parameters and signals alarms incase impermissible deviations occur.Alarm initiationAll impermissible deviations from operating pa-rameters as well as malfunctions cause alarm si-gnals to be issued and transmitted to the alarmsystems via a serial bus interface.2.3.3.3 Engine controlThe engine control system controls and moni-tors all engine functions, the speed control andthe auxiliary drive cabinet.Starting/stopping sequencesDemands regarding lube oil and cooling waterpumps, monitoring of the prelubrication andpost-cooling period, monitoring of the accelera-tion period.Control station switch-overSwitch-over from local operation in the engineroom to remote control from the engine controlroom and to the remote control system.Speed settingLocal and manual speed setting is realised bythe SaCoS operating panels. Automatic remotespeed setting is carried out by the propulsioncontrol system while remote control is selectedJet-assistTo improve the response of the engine to a newload condition, starting air is supplied to the tur-bocharger via a valve when load is applied.Pump controlThe demands regarding the electric pumps forlubricating oil and cooling water are issued bySaCoS. SaCoS also supplies the request signalsfor standby start of the lube oil and HT coolingwater pumps. The standby and pump logics areto be realised in an external pump control sys-tem.Temperature controlTemperature controllers for various operatingmedias are available. For more details, pleaserefer to chapter "temperature control" or chapterof the respective subsystems.2.3.3.4 Electronic speed controlThe electronic speed governing system includesthe control and regulating devices for the fuelrack actuator.The speed governing system effects the ex-change of all data required for safe and reliableoperation with the Safety and Control System.This data exchange is carried out via hardwareconnections. There is no direct connection be-tween the speed control and the superior plant-specific control system. Communication withthe plant-specific control system takes place viaSaCoS exclusively.Speed settingAn influence on speed is exerted by SaCoS. lncase of remote control, a set-point input by theplant-specific control system is possible eitherby means of binary contacts (e.g. for synchroni-sationl or alternatively by an active 4-20mA an-alogue signal via SaCoS.ln the case of local control, speed alteration isonly possible at the local engine control stand.Operating modesThe following operating modes are available asa standard: lsochronous Droop (with a 5-percent speed increase whenreducing load from nominal load to no load,as a standardl.The operating mode is preselected via the Sa-CoS interface and has to be defined during theapplication period.Details regarding special operating modes onrequest.Diesel engine and operation2.3.3 SaCoS Status 01/2006 Page 2 - 1250203-0104MA.fmLoad sharingln the case of multi-engine plants, load sharingis effected by a droop function. ln the isochro-nous operating mode, load distribution is possi-ble by direct intercommunication between thespeed governors. lnterfacesThe speed governing system is supplied withelectric power of the required voltage from thepower supply cabinet.
