51/60DF - MAN Diesel & Turbo Canada

Efficient and Compact51/60DF – The clean choiceCombining diesel and gas in one engine gives you the full flexibility in fuel usage.To imply the selection between diesel or gas fuel makes your engine running moreand more economical and the possibilities of high power output with low emissionsare trend-setting.Committed to the futureTechnologies which promise compliance with the IMOTier III round of emissions limits due in 2016 combinedwith further optimised fuel consumption and new levelsof power and flexibility are already under developmentat MAN Diesel & Turbo. With this level of commitmentMAN Diesel & Turbo customers can plan withconfidence.Core technologies in-houseAs well as its expertise in engine design, developmentand manufacture MAN Diesel & Turbo is also a leadingmanufacturer of the key technologies which determinethe economic and ecological performance of adiesel and gas engine:•High-efficiency exhaust gas turbochargers•Advanced electronic fuel injection equipment•Electronic hardware and software for engine control,monitoring and diagnosisOur impressive array of computer-aided design toolsand one of the engine industry’s largest, best-equippedfoundries allow us decisively to shorten productdevelopment, and application engineering processes.Our mastery of these engine technologies – and thebest brains in the large engine industry – are the firmfoundation for•Low emissions•Low operating costs•Low life cycle costs•Long service lifeThe range of technical measures employed comprises:•Improved charge air cooling•Enhanced turbocharging•Miller valve timing•Revised injection timing•Higher compression ratiosGaseous fuelsOn natural gas, the 51/60DF undercuts IMO Tier IIlevels by extremely wide margin – indeed, in gaseousfuel mode, the 51/60DF already fulfils the strictIMO Tier III NO x limitations prescribed for EmissionsControl Zones (ECA’s).Micropilot ignitionBuilding on this firm basis for low emissions, the51/60DF employs the latest “micropilot” gas ignitiontechnology. The gaseous fuel is ignited by injection of adistillate fuel pilot representing less than 1% of thequantity of liquid fuel needed to achieve the 51/60DF’sfull rated output in its liquid fuel back-up mode.Liquid fuelsThe 51/60DF complies with IMO Tier II NO x emissionslimits.Common rail pilot-fuel injectionThe 51/60DF pilot injection system uses the latestMAN Diesel & Turbo common rail technology whichallows flexible setting of injection timing, duration andpressure for each cylinder. This flexibility allows the fuelconsumption and emissions of the 51/60DF to beoptimised at any point on its operating profile. In gaseousfuel mode MAN Diesel & Turbo common railtechnology also allows the gas admission and pilotinjection of the 51/60DF to be very closely matched topower demand, even down to very low engine loads,e.g. when meeting only the vessel’s hotel load. Likewise,MAN Diesel & Turbo common rail technologyalso allows the 51/60DF to respond rapidly to combustionknocking and misfiring on a cylinder-by-cylinderbasis.ICC – Intrinsically clean combustionThe 51/60DF is designed to burn methane and gaseswith high methane content. As the simplest compoundof carbon and hydrogen in the hydrocarbon series,methane is essentially clean burning.4 51/60DF – Four-stroke dual-fuel engine51/60DF – Four-stroke dual-fuel engine 5

Engine Specifications51/60DF – “The reliable engine”The synonym for top performance with the highest level of flexibility. Theperformance of this potent marine engine lies in a range from 6,000 to 18,000 kW.For LNG carriers the 51/60DF is the right choice in every respect.GeneralThe 51/60DF engine from MAN Diesel & Turbo is adual-fuel marine engine that converts diesel fuel ornatural gas into electrical or mechanical propulsionpower efficiently and with low emissions. Incombi nation with a safety concept designed byMAN Diesel & Turbo for appli cations on LNG carriers,the multi-fuel capability of the engine represents anappropriate drive solution for this type of vessel, aswell as for other marine applications. The capabilityto change over from gas to diesel operation with outinterruption rounds off the flexible field of applicationof this engine.51/60DF now for bothelectrical and mechanical propulsionThe 51/60DF engine is now also available for mechanicalpropulsion in a wide range of applications. Comparedto the diesel-electric concept, the mechanical driveconcept leads to a higher total efficiency and lowerinvestment costs of the ship’s propulsion train.FuelsThe 51/60DF engine is designed for operation withliquid and gaseous fuels. In gas operation, the gasto be burnt has to meet the latest applicableMAN Diesel & Turbo directives for natural gas. Withliquid fuel, the 51/60DF engine can be operated withMGO, MDO and with heavy fuel oil up to a viscosity of700 mm²/s (cSt) at 50 ˚C. It is designed for fuels up toand in cluding the specification CIMAC 2003 H / K700 /DIN ISO 8217.Marine main propulsion enginesEngine output is limited to 100% of rated output forengines driving propellers. Engine output is limited to110% of rated output for engines driving a generator.Overload above 100% load is permitted briefly to preventa frequency drop during sudden load impositionin generator applications.Marine auxiliary enginesFuel stop power is 110% of rated output. Overloadabove 100% may only be used briefly to balance outfluctuations in frequency during load acceptance indiesel and gas modes.6 51/60DF – Four-stroke dual-fuel engine

Technical SpecificationsQuality insideEngine frameRigid housing in monoblock design (cast) with fulllength tie-rods from suspended main bearing to uppersurface of engine frame and tie-rods from cylinderhead to intermediate bottom.Cylinder linerThe cylinder liner, mounted in individual cylinder jacket,is free of deformations arising from the engine frameand thus assures optimum piston running, i.e. highservice life and long service intervals.Con-rods and con-rod bearingsOptimised marine head version with split joint in uppershaft area, thus no release of the con-rod bearing necessaryduring piston extraction; low piston extensionheight. Optimised shells for con-rod bearings increaseoperating safety.Stepped pistonsForged steel crown highly resistant to deformation (withshaker cooling) made from high grade material andnodular cast iron in lower section. In combi nation witha flame ring, the stepped pistons prevent undesirable“bore polishing” on the cylinder liner – and assurepermanently low lubricating oil consumption, i.e. lowoperating costs. Chrome ceramic coating of first pistonring with wear resistant ceramic particles in ring surfaceresults in low wear, i.e. long service life and longservice intervals.Cylinder headWith its combustion chamber geometry, the cylinderhead assures optimum combustion of gaseous andliquid fuels. Atomisation of the fuel spray in both operatingmodes is unimpeded – thus leading to verygood air: fuel mixture formation and an optimum combustionprocess, i.e. reduction in fuel consumption inboth oper ating modes.ValvesThe exhaust valves have water-cooled, armouredexhaust valve seat rings and thereby low valve temperatures.Pro pellers on the exhaust valve shaft causerotation of the valve due to the gas flow with resultantcleaning effect of the sealing surfaces. The inlet valvesare equipped with Rotocaps. This results in a low rateof wear, i.e. long service intervals.InjectionHigh pressure injection in liquid fuel mode with improvedatomisation for combustion of fuels with thelowest quality still accepted. In gas mode, ignitionis achieved via injection of a small quantity of pilotfuel by means of a common rail system. Overall,a fuel injection system optimised for low consumptionand low amount of harmful emissions.Rocker housingModified, weight-reduced rocker arm casing allowsquick replacement of injectors in gas and liquid fuelmodes. The components required for gas operationare completely integrated into the rocker housing.High design strength, good heat dissipation and aconfiguration for the highest ignition pressures ensurethat the unit has a very high level of component safety,i.e. long service life.8 51/60DF – Four-stroke dual-fuel engine 51/60DF – Four-stroke dual-fuel engine 9
