RT-flex TrainingService AspectsChapter 80RT-flex, Operation & Service Goals “ ”Goals of chapter “Operation and Service”:RT-flexTrainees will know to operate their RT-flex engine in a safeand economical wayRT-flex Trainees will be able to perform trouble shooting and basicmaintenance work on the RT-flex engineThings to consider during normal operation:flex The flex parts of the engine requires different treatment than used on conventional engines.However, for the mechanical parts in general refer to the manuals, your knowledge as an engineer and to common sense.On the following pages some important hints and tricks are listed but is not limited to.Please note that the tips, hints and remarks mentioned hereafter are just some possibilities to solve a problem based on experiences with real situationsHowever, the manuals delivered with the RT-flex engine and on-site given instructions from engine maker prevails these chapters.Remember that even at engine standstill, there is probably pressure remaining in the rails.Depressurise the rails and pipes before starting to work on them!RT-flex, Operation & Service Visual ChecksVisual checks on daily roundsThe top covers of the rail unit lift up easily, so look inside daily and check for leaks, etc.Regularly inspect the fuel pump regulating racks. Does it move freely on all pumps ? The rod can be push to a lower position, the other pumps will automatically compensate.Fuel-, Servo-and Control oil pumps, valves, distributionblocks, pipe connections, etc. have to be checked daily for possibleleaks.RT-flex, Operation & Service SafetyWorking on Pumps, valves and rail unitBefore starting any work on pumps, valves or rail unit make sure thatthere is no residual pressureRT-flex, Operation & Service After OverhaulAfter overhaul works in or around the rail unit and/or supply unitWECS-9520 flexview Make use of the simulation possibilities of WECS-9520 and flexView.Once the control oil pump or service pump is running, the exhaustvalves can be manually open and closed. This proves that they work properly and leakages can be detected.“Injection venting” ICU 30 To check the ICU, fuel pipes and injectors the function "Injectionventing" which will trigger all injection rail valves on-off for 30 seconds. Thisprocedure can be used to vent air from the newly assembled parts. Oil will flow through them and warm them up. Possible leaks can be seen.RT-flex, Operation & ServiceElectronic UnitsDo not use water washing devices anywhere near any electronic unit !2No welding work within 2 meters around a switched-on electronic units !RT-flex, Operation & Service FCM-20FCM-20 modulesE90 “ ” E95 The FCM-20 installed in E90 as “Online-Spare”can be installed in any E95 box.Make sure that ALL FCM-20’s in the store have the same softwareversion loaded than the ones used on the engine.WECS Power Supply RT-flex, Operation & ServiceWECS-9520WECS-9520ArrayThe electronic units of the WECS-9520 system shall always be kept on, there isno need to switch it off the electronic units inport. But it is recommended to turn off powerwhen unplugging sockets from modules andduring welding works on the engine.Power supply to a singlecylinder can be cut off even with runningengine, after switching back on the cylinder itwill boot and start working.RT-flex, Operation & ServiceRV-2, On-TimeRV-2The RV-2 rail valves are switching very fast to achieve a precise injection and exhaust valve timing.Typical on-times are:< 1.5 ms good1.6 –2.5 ms so so> 2.6 ms poor4.5 ms limit!!Protection guardsE95 The E95 boxes have to be protected against damage by using the protection guards.Protection against unexpected alarmsTo avoid a slow-down / shut-down released by accidentally pushed lever, protect it with a cover.RT-flex, Operation & Service Trace HeatingTrace heating of rail unit, supply unit and rising pipes (all fuel parts):4:RT-flex, Operation & Service Oil TreatmentOil treatmentRT-flex, Operation & Service Main Starting ValveFunction test of main starting valveflexview“slow turning” “air run”Injection unit, “quantity piston stuck in end position”ICUFCM“Sticking”does not always mean that the piston got physically seized. It mostly happened due to rail valve failed, fuel quantity sensor failed, FCM failure, cold control oil, etc.Very often the piston starts working again after a while with warm oil or after depressurizing the fuel rail.ICU. Normally replacing the ICU is NOT need.ICURT-flex, Operation & Service InjectionVenting of fuel oil rail:After a major overhaul or to fill up an empty fuel oil system, venting has to be done.ICU The venting plug in one ICUper rail must be slackened. Running the booster pump fills the rail with fuel while air and foam escapes from the plug.Some engine types have the possibility to pressurise the fuel rail via servo oil system.flexView Venting can also be done via flexView under “User”.Screw plug forleakage checkingOnly Wärtsiläallowed to overhaul ICU’s !RT-flex, Operation & Service Fuel press. regulating valveEmergency operation:A good value will be between600-700 bar.RT-flex, Operation & Service Exhaust Valve Drive(Tool Nr. 94586)VCUBlocking of exhaust valve:Nr. 94259If a cylinder cooling water leakage into combustion space occurs, the engine shall be operated with an open exhaust valve. Therefore the valve is moved open manually by user parameter (will close by itself after a short time!), and pins Nr. 94259 can beinserted.Of course the injection has to be cut off as well !Exocentric shaft Tool Nr: 94430Roller guide: :blank flange “8”(tool 94569)blank flange “15”(tool 94569a) intermediate fuelaccumulatorRegulating rackoccur, the position is kept on actual position.WECS-9520The crank angle signal is absolutely indispensable for engine operation.At least one of the sensors must be working. If one fails, WECS-9520 can detect the failure and will keep working with the healthy signal(plausibility check). In case both sensors fail, the engine will stopwithout delay.There is no emergency operation possible without at least one CA sensor!Crank angle sensors and –driveThe crank angle sensor drive has to be checked for proper lubrication. Check daily if the lube oil pipe feels warm. If not, the fine orifice at the inlet to the housing may be clogged.Open the cover every few months and look inside.• Are the belts OK and with correct tension ?• Is there any dirt or oil ?• Do sensor wheels have play ?0.03.5 kg4.5 kg2 Sensors with beltsand screws, 1 complete drive unitassembled.3~5 The belts have to be exchanged after a while (estimated lifetime 3 ~ 5 years).The belts must be free of oil !Dropped gear wheelGear wheel Worn faceSensor pulley, dropped off side ring: Consequence of over tightened belt.Apply Molykote tosliding surface!MolykoteFitting of shaft encoder1.2.3.4.CA-Sensor, complete with holder and cable.The two red lines must be inline when cylinder 1 is in TDC.The most important tools for trouble shooting on flex problems are:FlexControl DiagramAlarm-log, indications of actual valuesWiring diagrams of WECS-9520 (E87, E85, E90, E95, E94, E96, etc.)flexViewflexViewWith flexView trend lines can be used to find out if a value is unstable. The journal of the flexView shows directly the cause of the alarm.Combination of AlarmsSome situations create not one but a series of alarms. Since this can be confusing, the first one that came up is probably the root cause.Logical sense may still be required to pinpoint the exact source oftrouble. The current situation has to be analyzed. Has somebody done some work on the engine or the auxiliaries ? Switched on or off some equipment ?Replacing partsIt is NOT recommended just to replace parts with unclear status with new ones (used but probably OK). Try to find out the status by e.g.FCM-20 exchanging an FCM-20 module with one from an other cylinderexchanging a rail valve with one from an other cylinder Exchanging components with one from an other cylinders makes it very clear if a component is faulty or not. But check first that else is controlled by thesecomponents.Sensor fail alarms that go on and offThe following sensors can be disconnected: fuel quantity sensorsexhaust valve stroke sensorsrail pressure transmitterscrank angle sensor (the other one has to be operational !)RT-flex, Operation & Service Bosch Pump ControllerInputs:DI1Shows engine running direction (lit when astern)DI2Unused DI3Unused DI4Unused DI5Unused DI6Enable (should always be lit)DI7Unused DI8 UnusedOutputs:DO1 Swivel angle control is activeDO2 Pressure control is active.

Data below are for the R1 ratings on theusual layout fields and complying with IMO Tier I.DEFINITIONS AND NOTES FOR LOW-SPEED ENGINESDIMENSIONS AND WEIGHTSl All dimensions are in millimetres and are not binding.l The engine weight is net in metric tonnes (t), without oil and water, and is not binding.FUEL CONSUMPTIONAll brake specific fuel consumptions (BSFC) are quoted for fuel of lower calorific value 42.7 MJ/kg, and for ISO standard reference conditions (ISO 15550 and 3046).The BSFC figures for Wärtsilä engines are given with a tolerance of +5%. Wärtsilä RT-flex engines have a lower part-load fuel consumption than the corresponding Wärtsilä RTA engines. Wärtsilä RT-flex engines are also available with Delta Tuning and the RT-flex82C and RT-flex96C also with Low-Load Tuning for even lower part-load fuel consumptions (see chart). Low-Load Tuning will be introduced also to the other RT-flex engines in the portfolio.Typical BSFC curves to illustrate Standard Tuning Delta Tuning and Low-Load Tuning.Load, %BSFCDelta Tuning and Low-Load Tuning both take advantage of the complete flexibility in engine setting provided by the RT-flex common-rail system to optimize fuel injection pressures and timing at all loads. Delta Tuning focuses on reducing BSFC in the operating range below 90% engine load. Low-Load Tuning further reduces BSFC in the operating range below 75% engine load by means of a modified turbocharging system layout in combination with appropriately adjusted RT-flex system parameters.ISO STANDARD REFERENCE CONDITIONSTotal barometric pressure at R1 ............................................1.0 bar Suction air temperature ............................................25 °C Relative humidity ............................................30% Scavenge air cooling water temperature with sea water .........25 °C Scavenge air cooling water temperature with fresh water .......29 °CIMO NO X EMISSIONSAll Wärtsilä low-speed engines included in this booklet comply with theNO X limits specified in Annex VI of the MARPOL 73/78 convention. For the amended regulations under IMO Tier II and Tier III, please see page 6.The latest versions of these engine types are available either complying with the amended regulations under IMO Tier II, or complying with the existing IMO Tier I regulations. Previous versions of these engine types comply only with existing IMO Tier I regulations.Compliance with the IMO Tier II NO X emissions limits involves a small increase in fuel consumption compared with the BSFC with the Tier I limits. Wärtsilä RT-flex electronically-controlled common-rail low-speed engines will comply with the Tier II NO X emissions limits with a smaller increase in fuel consumption than Wärtsilä RTA low-speed engines.Provisions for compliance with IMO Tier III NO X emissions limits will be announced at a later date but in ample time for the implementation date.RATING POINTS FOR WÄRTSILÄLOW-SPEED ENGINESThe engine layout fields for Wärtsilä low-speed engines are defined by the power/ speed rating points R1, R2, R3 and R4 (see diagram right). In certain engines, the layout field is extended to the points R1+ and R2+. R1, or R1+ instead if applicable, is the nominal maximum continuous rating (MCR). Any power and speed within the respective engine layoutCYLINDER LUBRICATIONThe load-dependent accumulator cylinder lubricating system has proven reliable in operation since its introduction in the 1970s. It is employed as standard on Wärtsilä RTA low-speed engines of smaller bore.To enable lubricating oil feed rates to be reduced the accumulator system has been further developed in recent years. The new Pulse Lubricating System with electronic control of lubrication timing has been developed. It is available for all Wärtsilä RT-flex low-speed engines and for selected RTA engines. The guide lubricating oil feed rate with the Pulse Lubricating System is0.7– 0.8 g/ k Wh. This allows important savings in engine operating costs.For further information on this subject, please consult your nearest WärtsiläWÄRTSILÄ PROPULSION PACKAGES WITH LOW-SPEED ENGINESWärtsilä propulsion packages are available that combine low-speed engines and controllable or fixed pitch propellers.

瓦锡兰4L20机的拆、装程序

瓦锡兰4L20机的拆、装程序（正体为厂家说明书，斜体为建议注意项，程序由广远技术部门编写，仅供各司参考）连杆大端轴承的安装开始时,先盘车使该缸的曲轴颈至适当的位置,即由该缸上死点位置向操控端方向转55度的位置上。

该位置在装上连杆螺栓液压工具后，保证液压工具不会碰到道门。

在装上连杆螺栓液压工具后，应检查液压工具与道门间必须都有间隙，NO.1缸由于其结构特点更需特别注意。

液压工具碰到道门会使液压压力不准导致螺母上不紧或上不均。

1. 对大端轴的上轴瓦,不论是运行面和背面都涂上一层薄的滑油膜,然后把上轴瓦安装到连杆轴承上,轴瓦的定位凸耳要接合到连杆轴承的凹槽上,然后安装好。

必须保证接触面的清洁，以防杂质残留在轴瓦的运行面和背面。

大端上连杆螺栓的螺孔应检查，必要时清洁。

如果原来连杆螺栓根部已没有底塞，即连杆螺栓与大端在根部是铁碰铁，可能会有磨损。

2.吊起活塞连同连杆,小心地把活塞往下放到该缸套里面。

3.在曲轴颈涂上一层薄油膜,把活塞再往下放,一直放到连杆可以坐在曲轴颈上。

4.在下轴瓦的运行面和背面都涂上一层滑油薄膜,把下轴瓦安装在轴承盖上。

必须保证连杆大端各部件接触面的清洁。

以防杂质残留在轴瓦的运行面和背面及连杆螺母与轴承盖接触面上，造成一对连杆螺栓螺母安装时上紧度的假象或不均。

5.举起轴承盖,安放到位,同时把上面一根螺栓，用手安装到位,一直旋紧到底为止。

厂家建议连杆大端解体后，全部换新底塞，换新底塞时，应彻底清除螺孔内的杂物。

此底塞只起防止铁碰铁的作用，如现运行中的副机估计无底塞且已铁碰铁（从测量连杆螺栓自由端露出螺母的长度可判断），建议在供到备件后尽快更换，更换时必须拆下连杆大端，并对连杆大端各部件接触面彻底清洁，禁止不拆下大端、不清洁各部件而轮流单根更换底塞。

如估计有底塞，只是尺寸变小，可在下次连杆大端解体时更换。

6.安装上螺栓的螺母,用手扭紧螺母,检查连杆轴承细齿和轴承盖细齿在相关的正确的位置上。
