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 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 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...
