2.0 Installation Aspects 2 .1 O il i n j e c t i o n v a l v e s ( No n r e t u r n v a l v e s )
For newbuildings the cylinder liners are delivered with tangential oil injection valves. One of the valves in each cylinder is designed / prepared for measuring. The measuring valve is equipped with two mini-mess couplings, one for cylinder pressure measurement and one for injection pressure measurement. This way the timing of the lubricator system can be checked. Detail drawings: MS 05, MS 64. For retrofit installation the oil injection valves, fittings and mini-mess couplings have to be designed specifically for the engine’s cylinder liner design. Regarding the modification procedure for existing cylinder liners with the “old” traditional oil injection valves, please contact MBD-C, Technical Service Dept. 2 .2 L u b r i c a t o r u n i t s
The lubricator units are installed close to the oil injection valves. The position differs with engine size, depending on space availability, and the design comprises two lubricators for 90-70 bore and one lubricator for 60-35 bore engines. Detail drawings for new buildings: MS 63. The lubricators for a particular engine have been specified with a certain stroke, which is based on the desired basic cyl. oil feed rate at MCR. The distance piece length in all lubricators can be checked against a calculation of the basic cyl. oil feed rate. See paragraph 3.1.1 Checking of lubricator stroke. The lubricator units are equipped with accumulators, which have to be pressurized with nitrogen before entering service. Regarding pressure filling with nitrogen please see section 3.1.2 and Instruction book Volume II paragraph 903-2.1. 2 .3 I n t e r m e d i a t e b o x e s
These terminal boxes, of which there are one per cylinder, are equipped with feed back LED´s for each lubricator. They are installed usually on the middle gallery and mounted on a small plate or angle iron. Note! Two electrical diodes (type 1N4007 1000V, 1A or similar) has to be installed in the screw terminal. See electrical drawings. Detail drawings for new buildings: MS 63. 2 .4 P u m p S t a t i o n
The pump station is a complete unit, which is supplied by a subcontractor. The unit is as standard supplied with starter panels and HMI panel included. See maker’s instruction manual. The unit can be installed on the engine or in the ship’s hull structure. Detail installation drawings: MS 00 / MS 64.

3.0 Commissioning - Mechanical 3 .1 L u b r i c a t o r u n i t s
3.1.1 Checking of lubricator stroke The calculation described below is based on Microsoft Excel 2000, but an earlier Excel version or manual calculation is sufficient. Basic cyl. oil feed rate This calculation serves to check the layout of the stroke limiter (distance piece) in the displacement end of the lubricator. Fill in the EXCEL sheet Basic_adj.xls in the Appendix, and insert the desired basic cyl. oil feed rate at 100 % MCR load of the engine. The calculated stroke should match the length of the stroke limiters in the lubricators. Carry out adjustments, if required. 3.1.2 Filling of N2 in accumulators Condition: Atmospheric pressure on the oil side of accumulators. For newbuildings we recommend that the pressure setting of accumulators is done before the lubricator units are mounted on the engine. Pressure setting 0.7 l accumulators (inlet side):
25 - 30 bar
(0-60 bar press. gauge)
Mount the mini-mess coupling with the drain hose on the lubricator block in order to obtain atmospheric pressure on the oil side of the accumulator. 0.16 l accumulators (outlet side):
1.5 bar (0-10 bar press. gauge)
Dismantle the accumulators in order to obtain atmospheric pressure on the oil side. For use of the standard pressure setting tool, see separate instruction.
3 .2 B a c k - u p T r i g g e r S y s t e m c h e c k
Turn the engine to TDC piston # 1 and check that • the marker plate for the back-up pick ups is positioned correctly opposite the pick ups. • the marker & trigger pick ups are correctly positioned in case of trigger ring.

3 .3 P u m p S t a t i o n
The pump station has as earlier mentioned been supplied by a subcontractor, and consequently the preparation for start-up and general operation is described in the maker’s instruction manual. Regarding the installation, check that the unit and pipe system has been designed and installed in accordance with drawing 0788334-8. See Appendix.
3 .4 F l u s h i n g
We recommend that flushing of the Alpha lubricator pipe system is done at the same time as flushing of the other oil systems (system oil, cam shaft oil, fuel oil). In the Appendix please find a sketch of the recommended flushing condition of the pipe system and carry out the following: 1. Install a 15 - 35 µ full flow filter on the return side of the pipe system just before the pump station. The outlet must drain into the suction tank. 2. Install flexible hydraulic hoses or U-pipes on the inlet / outlet side of each Alpha lubricator unit. 3. Fill enough hydraulic oil or thin mineral oil in the suction tank of the pump station, that the pumps do not run dry, when the pipe system is f illed. 4. Remove (or by-pass) the filter(s) on the pressure side of the pump station. 5. Start the pump station in accordance with the maker’s instructions. 6. Run both pumps, in order to obtain turbulent flow and high temperature. 7. Flush the pipe system for at least 5 hours. 8. Approve the flushing, when a cleaned (or new) filter is still clean after yet another hour of flushing. 9. Drain off the flushing oil from the pump station and re-establish the pipe system to normal operation. Open the cylinder oil supply. 10. Start the pump station and adjust the output pressure to 45 bar. 11. All 8 mm lubrication pipes from the Alpha Lubricators to the cylinder liners must be blown through with compressed air before eventual activation of the lubricators.

1. Timing measurement equipment consisting of oscilloscope, absolute pressure transducers with adaptor for mini-mess, amplifiers, cables, PC, printer, etc. must be available. An example of timing equipment is specified in the Appendix. 2. Check that two mini-mess couplings are installed on all cylinder units in a convenient position at the cylinder oil injection valve “for measuring”. 3. Assemble the two pressure transducers with the adaptors for the mini-mess couplings. 4. Install the adaptors with pressure transducers in the mini-mess couplings and tighten only by hand.

5. Connect the cables between the pressure transducers and the amplifiers, while making sure that the contact plugs are absolutely clean. Use the cleaning agent. 6. Adjust the scale on the amplifiers so that they match the calibration value, stamped on the pressure transducer elements. (See also certificate from maker). 7. Connect the amplifiers to the oscilloscope by means of the COAX cables. 8. Prepare the 220 V power source.
4.0 Commissioning – Electrical We recommend that all installation incl. wiring is completed 32 hours prior to engine start up in order to allow time for electrical checks / tests / simulation and correction of potential mechanical / electrical errors. 4.1 Tools
For electrical commissioning of Alpha Lubricator System the following tools are necessary: Configuration of MCU • PC, serial cable RS232, Excel sheets, Set-up programme, Basic program, Set-up file, VT 100 Terminal. Configuration of BCU • Philips Winisp flash programme, set-up file. Testing • Timing measurement tools (See specification in Appendix) • Trigger simulator (See specification in Appendix) Normally the MCU and BCU are configured specifically for the engine before shipment from MBD Copenhagen. These procedures are described in section 4.2 and 4.3.

4.2.1 Excel sheets The following two excel sheets with specific engine data are to be filled out in order to generate relevant parameters for the MCU set-up program. Index transmitter adjustment The injection rate during MCU control is adjusted to be proportional to the engine MEP. The excel sheet calculates the MinIndexLevel and MaxIndexlevel parameter after various engine data have been entered. See example in Appendix. Engine kinematics / Timing The injection timing of the cylinder oil is calculated to start during each piston’s upward stroke, when the top piston ring passes the oil quill. The point of reference in the timing calculation is defined as The distance between the edge of the top piston ring for piston # 1 in TDC position and the location of the oil quill in the cylinder liner. The timing of the remaining cylinder units is calculated from the crankshaft angles, the firing order, various physical sizes and the number of trigger pulses of the angle encoder / trigger ring. The excel sheet calculates the Crank angle for injection for each cylinder. See example in Appendix.

SW1 position 1 – 4 Injection rate with BCU in control Generally a BCU take-over should result in a cylinder feed rate increase of 50 %, which in case of a MCU Basic feed rate of 4 rev. / inj. corresponds to a BCU injection rate of 3 rev. / inj. Example: If SW1.1-2 is ON and SW1.3-4 is OFF, the injection rate will be 3 rev. / inj. C_Manual02.doc

Press the “PRE-LUB” button on the HMI panel, and check that all lubricators are operating correctly by watching the LED’s (feed back signals) for each cylinder. Check visually from the scavenge air receiver that all non return valves are injecting cylinder oil into the cylinder liners. Wear eye protection ! Check that the cooling water system for the oil cooler on the pump station is correctly installed and that the valves in the supply -and return lines are open. Check on the HMI panel that the cylinder oil feed rate individual adjustment is set to the desired value (default = 100 %). Normally the setting during breaking-in of the piston rings and cylinder liners is 200 %.

5.3.1 De-aeration of pressure transducers 1. Start by checking the timing equipment, which has been prepared in accordance with section 3.5. The two pressure transducers are to be positioned in cylinder 1. Tighten the adapters in the mini-mess by hand only. 2. The engine should run with at least 50 % load in order to obtain acceptable readings. 3. Carry out de-aeration by opening the adapter venting valve for the pressure transducer mounted in the mini-mess for the lubricator injection pressure. Close the venting valve, when oil flows out. 4. Re-locate the pressure transducer with adapter, which has just been vented, to the position for the cylinder pressure. The unit is filled with oil and is not to be vented again. 5. Install the other pressure transducer with adapter in the mini-mess for the lubricator injection pressure. Carry out de-aeration according to item 3. 6. Power up the timing equipment and adjust the scales on the oscilloscope so that the size of the pressure curves match the display. Warning! Never disconnect the communication cable between a pressure transducer and an amplifier, which is operating. You may damage the equipment ! 5.3.2 Measurement of hydraulic/mechanical delay The hydraulic/mechanical delay [OffsetMecDelay] is a MCU configuration parameter, which is to be recorded and up-loaded to the MCU before the actual timing measurements are recorded. Please note that the engine has to be stopped for up-loading of MCU. The value is to be inserted in ms/2. 1. Mount one pressure transducer with adapter in the mini-mess for lubricator injection pressure cyl. 1. 2. Connect the oscilloscope measuring probe channel 1 to the lubricator injection pressure transducer cyl. 1. 3. Connect the oscilloscope channel 2 to plug J1, terminal 4 (Feedback indication signal for injection cyl. 1) and plug J14, terminal 2 (ground) and on the MCU. 4. Measure the time between the first flank of channel 2 and the point at which the pressure curve starts to build up for channel 1. T his time interval is defined as the hydraulic/mechanical delay.

5.3.3 Measurement of individual cylinder injection timing 1. Mount the two pressure transducers with adapter in the mini-mess for lubricator injection pressure cyl. 1. Carry out de-aeration in accordance with paragraph 5.3.1. 2. Connect the oscilloscope channel 1 to the lubricator injection pressure transducer cyl. 1 and channel 2 to the cylinder pressure transducer cyl. 1. 3. When a set of curves have been recorded for one cylinder, move the two pressure transducers in the adaptors to the next cylinder without disconnecting the communication cables. 4. Do not carry out de-aeration of channel 2, after a moving the equipment from one cylinder to another. If the signals are drifting, clean the connections with the cleaning agent, while making sure that the amplifiers are turned off. 5. Carry out the timing measurements by recording sets of curves successively for all cylinders in a series. 6. Evaluate the timing measurement curves as follows: The cyl. oil injection is to start approximately 1 ms before piston ring # 1 passes the oil quill. In other words, the injection pressure curve (channel 1) should cross the cyl. pressure curve (channel 2) approximately 1 ms before it’s maximum. 7. Carry out potential timing adjustments on the MCU configuration parameter [C_InjOffset(0)]. This value is inserted in degrees x 10 and is set as default to 300.

Forced LCD True: LCD active, False: LCD not active LCD trigger level in per cent fuel index within the time limit set by c_IndexDevTimeLCD LCD deviation time. LCD activation time. Amount of extra lubrication in per cent of actual feed rate, when LCD is activated. Lower alarm limit for engine speed. Rpm value at MCR. Oil pressure at 20 mA. Max. sensor temperature. Number of lubricators per cylinder True: One lubricator False: Two lubricators Number of activation of each lubricator, during automatic Pre-lubrication. Speed of sequence. Time until activation of the next lubricator during automatic pre-lubrication. Number of activation of each lubricator, during manual Pre-lubrication. Speed of sequence. Time until activation of the next lubricator during manual pre-lubrication.
Parameter name c_CylInjectionOrder [x] [Cyl. n - 1]

Description Cylinder injection order, starting with the first cylinder to be injected after TDC # 1. The [x] indicates a successive output-number for injection. The SW counts from 0, i.e. all cylinder numbers in the firing order have been subtracted by 1. Shaft torsion at 100 % load, following the c_CylInjectionOrder. The two pumps run alternately and shift every c_PumpIntervalTime time. Stop delay time of pump station active pump, when engine stops. Injection trigger number (angle) for cylinder[x]. The number equals c_InjOffset+(c_TrigPosCh1[xx]/c_Total TrigCh1) Selection of trigger / marker system.
