19 MAN B&W 1.01 The ME Tier II Engine Page 1 of 3 The ever valid requirement of ship operators is to obtain the lowest total operational costs, and especially the lowest possible specific fuel oil consumption at any load, and under the prevailing operating conditions. However, low speed two stroke main engines of the MC type, with a chain driven camshaft, have limited flexibility with regard to fuel injection and exhaust valve activation, which are the two most important factors in adjusting the engine to match the prevailing operating conditions. A system with electronically controlled hydraulic activation provides the required flexibility, and such systems form the core of the ME Engine Control System, described later in detail in Chapter 16. Concept of the ME engine The ME engine concept consists of a hydraulicmechanical system for activation of the fuel injection and the exhaust valves. The actuators are electronically controlled by a number of control units forming the complete Engine Control System. has specifically developed both the hardware and the software in house, in order to obtain an integrated solution for the Engine Control System. The fuel pressure booster consists of a simple plunger powered by a hydraulic piston activated by oil pressure. The oil pressure is controlled by an electronically controlled proportional valve. The exhaust valve is opened hydraulically by means of a two stage exhaust valve actuator activated by the control oil from an electronically controlled proportional valve. The exhaust valves are closed by the air spring. The starting valves are opened pneumatically by electronically controlled On/Off valves, which make it possible to dispense with the mechanically activated starting air distributor. By electronic control of the above valves according to the measured instantaneous crankshaft position, the Engine Control System fully controls the combustion process. System flexibility is obtained by means of different Engine running modes, which are selected either automatically, depending on the operating conditions, or manually by the operator to meet specific goals. The basic running mode is Fuel economy mode to comply with IMO NOx emission limitation. Engine design and IMO regulation compliance The ME-C engine is the shorter, more compact version of the MC engine. It is well suited wherever a small engine room is requested, for instance in container vessels. The ME-GI is a dual fuel engine burning natural gas, otherwise sharing the same compact design as the ME-C engine. It is designed for the highly specialised LNG carrier market. For MAN B&W ME/ME-C/ME-GI-TII designated engines, the design and performance parameters have been upgraded and optimised to comply with the International Maritime Organisation (IMO) Tier II emission regulations. The potential derating and part load SFOC figures for the Tier II engines have also been updated. For engines built to comply with IMO Tier I emission regulations, please refer to the Marine Engine IMO Tier I Project Guide. In the hydraulic system, the normal lube oil is used as the medium. It is filtered and pressurised by a Hydraulic Power Supply unit mounted on the engine or placed in the engine room. MAN B&W ME/ME C/ME GI-TII engines

20 MAN B&W 1.01 Page 2 of 3 ME Advantages The advantages of the ME range of engines are quite comprehensive, as seen below: Lower SFOC and better performance parameters thanks to variable electronically controlled timing of fuel injection and exhaust valves at any load Appropriate fuel injection pressure and rate shaping at any load Improved emission characteristics, with smokeless operation Easy change of operating mode during operation Simplicity of mechanical system with well proven simple fuel injection technology familiar to any crew Control system with more precise timing, giving better engine balance with equalized thermal load in and between cylinders System comprising performance, adequate monitoring and diagnostics of engine for longer time between overhauls Lower rpm possible for manoeuvring Better acceleration, astern and crash stop performance Integrated Alpha Cylinder Lubricators Up gradable to software development over the lifetime of the engine It is a natural consequence of the above that more features and operating modes are feasible with our fully integrated control system and, as such, will be retrofittable and eventually offered to owners of ME engines. Differences between MC/MC-C and ME/ME-C engines The electro hydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators MAN B&W ME/ME C/ME GI-TII engines

26 MAN B&W 1.04 Page 1 of 1 Engine Power Range and Fuel Oil Consumption Engine Power The following tables contain data regarding the power, speed and specific fuel oil consumption of the engine. Engine power is specified in kw for each cylinder number and layout points L 1, L 2, L 3 and L 4 : Discrepancies between kw and metric horsepower (1 BHP = 75 kpm/s = kw) are a consequence of the rounding off of the BHP values. L 1 designates nominal maximum continuous rating (nominal MCR), at 100% engine power and 100% engine speed. L 2, L 3 and L 4 designate layout points at the other three corners of the layout area, chosen for easy reference. Power L 3 L 1 L 2 Specific Fuel Oil Consumption (SFOC) The figures given in this folder represent the values obtained when the engine and turbocharger are matched with a view to obtaining the lowest possible SFOC values while also fulfilling the IMO NOX Tier II emission limitations. Stricter emission limits can be met on request, using proven technologies. The SFOC figures are given in g/kwh with a tolerance of 5% and are based on the use of fuel with a lower calorific value of 42,700 kj/kg (~10,200 kcal/kg) at ISO conditions: Ambient air pressure...1,000 mbar Ambient air temperature C Cooling water temperature C Although the engine will develop the power specified up to tropical ambient conditions, specific fuel oil consumption varies with ambient conditions and fuel oil lower calorific value. For calculation of these changes, see Chapter 2. L 4 Speed Lubricating oil data Fig : Layout diagram for engine power and speed Overload corresponds to 110% of the power at MCR, and may be permitted for a limited period of one hour every 12 hours. The cylinder oil consumption figures stated in the tables are valid under normal conditions. During running in periods and under special conditions, feed rates of up to 1.5 times the stated values should be used. The engine power figures given in the tables remain valid up to tropical conditions at sea level as stated in IACS M28 (1978), i.e.: Blower inlet temperature C Blower inlet pressure mbar Seawater temperature C Relative humidity...60% MAN B&W ME/ME-B/ME C engines

28 MAN B&W 1.06 ME Engine Description Page 1 of 6 Please note that engines built by our licensees are in accordance with drawings and standards but, in certain cases, some local standards may be applied; however, all spare parts are interchangeable with designed parts. Some components may differ from s design because of local production facilities or the application of local standard components. In the following, reference is made to the item numbers specified in the Extent of Delivery (EoD) forms, both for the Basic delivery extent and for some Options. Bedplate and Main Bearing The bedplate is made with the thrust bearing in the aft end of the engine. The bedplate consists of high, welded, longitudinal girders and welded cross girders with cast steel bearing supports. For fitting to the engine seating in the ship, long, elastic holding down bolts, and hydraulic tightening tools are used. The bedplate is made without taper for engines mounted on epoxy chocks. The oil pan, which is made of steel plate and is welded to the bedplate, collects the return oil from the forced lubricating and cooling oil system. The oil outlets from the oil pan are normally vertical and are provided with gratings. Horizontal outlets at both ends can be arranged for some cylinder numbers, however this must be confirmed by the engine builder. Frame Box The frame box is of welded design. On the exhaust side, it is provided with relief valves for each cylinder while, on the manoeuvring side, it is provided with a large hinged door for each cylinder. The crosshead guides are welded on to the frame box. The frame box is bolted to the bedplate. The bedplate, frame box and cylinder frame are tightened together by stay bolts. Cylinder Frame and Stuffing Box The cylinder frame is cast, with the exception of the S65ME C which is welded, and is provided with access covers for cleaning the scavenge air space, if required, and for inspection of scavenge ports and piston rings from the manoeuvring side. Together with the cylinder liner it forms the scavenge air space. The cylinder frame is fitted with pipes for the piston cooling oil inlet. The scavenge air receiver, turbocharger, air cooler box and gallery brackets are located on the cylinder frame. At the bottom of the cylinder frame there is a piston rod stuffing box, provided with sealing rings for scavenge air, and with oil scraper rings which prevent crankcase oil from coming up into the scavenge air space. Drains from the scavenge air space and the piston rod stuffing box are located at the bottom of the cylinder frame. The main bearings consist of thin walled steel shells lined with bearing metal. The main bearing bottom shell can be rotated out and in by means of special tools in combination with hydraulic tools for lifting the crankshaft. The shells are kept in position by a bearing cap.

29 MAN B&W 1.06 Page 2 of 6 Cylinder Liner The cylinder liner is made of alloyed cast iron and is suspended in the cylinder frame with a low situated flange. The top of the cylinder liner is fitted with a cooling jacket. The cylinder liner has scavenge ports and drilled holes for cylinder lubrication. Cylinder liners prepared for installation of temperature sensors is basic execution on engines type 98 and 90 as well as on K80ME-C9 while an option on all other engines. Cylinder Cover The cylinder cover is of forged steel, made in one piece, and has bores for cooling water. It has a central bore for the exhaust valve, and bores for the fuel valves, a starting valve and an indicator valve. The cylinder cover is attached to the cylinder frame with studs and nuts tightened with hydraulic jacks. Crankshaft The crankshaft is of the semi built type, made from forged or cast steel throws. For engines with 9 cylinders or more, the crankshaft is supplied in two parts. At the aft end, the crankshaft is provided with the collar for the thrust bearing, a flange for fitting the gear wheel for the step up gear to the hydraulic power supply unit if fitted on the engine, and the flange for the turning wheel and for the coupling bolts to an intermediate shaft. At the front end, the crankshaft is fitted with the collar for the axial vibration damper and a flange for the fitting of a tuning wheel. The flange can also be used for a Power Take Off, if so desired. Coupling bolts and nuts for joining the crankshaft together with the intermediate shaft are not normally supplied. Thrust Bearing The propeller thrust is transferred through the thrust collar, the segments, and the bedplate, to the end chocks and engine seating, and thus to the ship s hull. The thrust bearing is located in the aft end of the engine. The thrust bearing is of the B&W Michell type, and consists primarily of a thrust collar on the crankshaft, a bearing support, and segments of steel lined with white metal. Engines type 60 and larger with 9 cylinders or more will be specified with the 360º degree type thrust bearing, while the 240º degree type is used in all other engines. s flexible thrust cam design is used for the thrust collar on a range of engine types. The thrust shaft is an integrated part of the crankshaft and it is lubricated by the engine s lubricating oil system. Step up Gear In case of engine driven HPS, the hydraulic oil pumps are mounted on the aft of the engine, and are driven from the crankshaft via step up gear. The step up gear is lubricated from the main engine system. Turning Gear and Turning Wheel The turning wheel is fitted to the thrust shaft, and it is driven by a pinion on the terminal shaft of the turning gear, which is mounted on the bedplate. The turning gear is driven by an electric motor with built in gear with brake. A blocking device prevents the main engine from starting when the turning gear is engaged. Engagement and disengagement of the turning gear is effected manually by an axial movement of the pinion. The control device for the turning gear, consisting of starter and manual control box, can be ordered as an option. MAN B&W ME/ME C engines
