The 49/60DF is already obtainable for order and relies on the brand new 49/60 engine platform that options MAN’s newest applied sciences.
It wouldn’t be SMM with out main engine bulletins and this week MAN Energy Solutions used the Hamburg commerce truthful to introduce the newest addition to its four-stroke engine portfolio: the MAN 49/60DF. The dual-fuel engine is able to working on LNG, diesel and HFO in addition to numerous extra sustainable fuels together with biofuel blends and artificial pure fuel.
MAN Energy Solutions says the brand new engine units a benchmark in phrases four-stroke gasoline effectivity—each in fuel and diesel modes—minimizes gasoline prices.
TICKET TO TRANSITION
“Dual-fuel engines are the ticket to the maritime energy transition,” mentioned Wayne Jones OBE, member of the chief board, world gross sales & after gross sales, at MAN Energy Solutions. “As we enter a new era of decarbonization, the 49/60DF is a great, new choice for vessel owners that have ambitious, emission-reduction targets on their agenda. In essence, it offers full fuel-flexibility to operators who can then choose from the various decarbonization paths that open up as new fuels make their way into the marine industry.”
Marita Krems, head of four-stroke marine & license at MAN Energy Solutions, mentioned: “The MAN 49/60DF is making its debut at a time where – while the number of LNG projects is still growing—alternative fuels like methanol, ammonia and hydrogen are continuing their rise, albeit with none having established market dominance as of yet. Increasingly, it is crucial for new vessels to be driven by engines that provide options for emission compliancy over the vessel’s lifetime. Fuel flexibility and efficiency are the key features. In this respect, the 49/60DF distinguishes itself by offering a number of various emission paths. It also has a level of efficiency that ensures best fuel costs in many applications, especially within the cruise, RoPax, RoRo, dredge, and LNG carrier segments.”
The 49/60DF is already obtainable for order and relies on the brand new 49/60 engine platform that options MAN’s newest applied sciences, together with two-stage turbocharging, second-generation common-rail gasoline injection, SaCoS5000 automation system and MAN’s subsequent era adaptive combustion management ACC 2.0 that robotically units combustion to optimum ranges. The engine additionally retains current MAN applied sciences such because the gas-injection system, pilot-fuel-oil system and MAN SCR (selective catalytic discount) system.
MULTIPLE COMPLIANCY PATHS
The 49/60 can begin in fuel mode the place it complies with IMO Tier III with out secondary measures. In diesel mode, it complies with Tier III mixed with MAN’s SCR system.
Soot emissions are halved in diesel mode on account of MAN’s new frequent rail system 2.2, whereas the 49/60DF’s methane emissions additionally drastically decreased in fuel mode in comparison with its predecessor. The engine’s benchmark effectivity and fuel-flexible design gives a number of paths to emission compliancy main as much as 2050, as per the present Fuel EU draft.
MAN Energy Solutions plans to introduce a pure diesel engine primarily based on the 49/60 platform in 2023 that can inherently be retrofit-ready for working on methanol and LNG ought to the demand come up at a later stage.
