General Information The MAN Diesel Tier II Engine Programme International Maritime Organisation (IMO) has Introduced new tightened regulations on the emissions for main engines Installed on ships with kee laying after 1 January 2011 h this context, electronically controlled engines, ME types, will have an The latest engines In our current Tier I programme are now available as Tier II engines with upgraded and optimised design and performance pa- rameters for Tier II compliance. Also a range of earlier engine models are available as Tier II optimised engines as listed In the table on pages...

General Information Dual Fuel Engines All ME engines are available for using natural gas as dual fuel engines with high pressure gas Injection, designated ME-GI (Gas Injection). This engine programme Includes the S70ME-GI, S65ME-GI and S60ME-GI. Power, speed and gross efficiency are the same as for the corresponding ME en- The MAN Diesel two-stroke MC-C/MC engines are characterised by hav- ng mechanically-driven camshaft-controlled timing of the fuel Injection exhaust valves and starting air valves, of which only the fuel Injection timing can be adjusted while the engine Is running If VIT...

General Information 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 NOxTier 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/ ■ Ambient air pressure 1,000 mbar ■ Cooling water temperature 25 °C Layout Diagram The...

General Information Waste Heat Recovery Waste heat can be economically recovered from all MAN B&W two-stroke engines from 50 cm bore and up, by Installing equipment for Waste Heat Recovery (WHR), and by matching the engine for WHR. A standard WHR-matched MAN B&W two-stroke engine will have a higher exhaust gas temperature compared with an engine without WHR, and can produce an extra electric power output corresponding to approx. 10% of the engine shaft power. Total system efficiency will therefore be better than that of the engine Itself. The minimum lengths Lmin are stated from the aft end...

General Information Engines with 60 cm bore and above Based on calculations of the aver- age worldwide sulphur content engines, the average cylinder oil consumption will be less than 0.65 Absolute dosage g/kWh; Engines with 50 cm bore and below - ACC dosage for BN70 cylinder oil Based on calculations of the aver- age worldwide sulphur content engines, the average cylinder oil consumption will be less than Further Information on cylinder oil as a function of fuel oil sulphur content and alkalinity of lubricating oil Is available from MAN Diesel The final and binding design of the MAN B&W...

General Information IMO Tier II Compliant Engine Programme While power density and fuel economy have always been in the focus of diesel engine developers, MAN Diesel is going one step further and has committed itself to further reduce the environmental impact of its diese With the current engine programme, MAN Diesel is already offering a com- plete portfolio of IMO Tier II compliant diesel engines for the entire power By applying engine internal and well proven measures which lead to a cleaner and more efficient combustion MAN Diesel is able to decrease noxious emissions without exhaust...

General Information Dual Fuel (DF) Engines Dual fuel engines from MAN Diesel efficiently run on liquid fuels or natural gas with emissions far below the IMO limit. The possibility to switch over seamlessly from gas to diesel operation and vice versa provides full flexibil- ity In multiple applications. All dual fuel engines can run on natural gas with a methane number higher than 80 without adjustments. For lower methane numbers, MAN Diesel Is In a position to deliver well adapted solutions. The optimised combustion chamber gives very low fuel consumption In both operational modes The...

General Information Engine Power The engine brake power is stated in kW. For conversion between kW and metric horsepower, please note that 1 bhp = 75 kpm/s = 0.7355 kW. Ratings are given according to ISO 3046-1:2002. The power figures in the tables remain valid up to tropical conditions at sea ■ Compressor inlet temperature 45°C ■ Compressor inlet pressure 1,000 mbar Specific Fuel Oil Consumption (SF0C) & Heat Rate The stated consumption figures refer to the following ISO reference ■ Ambient air pressure 1,000 mbar ■ Cooling water temperature upstream of charge air cooler 25 °C (77 °F) The...
