MAN launches new dual-fuel engine

MAN Power Options has launched its MAN 49/60DF engine kind on the SMM commerce honest in Hamburg. The most recent addition to its four-stroke engine portfolio, the dual-fuel engine is able to operating on LNG, diesel and HFO in addition to quite a few extra sustainable fuels together with biofuel blends and artificial pure fuel.

MAN Power Options states that it units a benchmark by way of gasoline effectivity inside four-stroke engines—each in fuel and diesel modes—and subsequently minimizes gasoline prices.

The MAN 49/60DF is making its debut at a time the place—whereas the variety of LNG tasks continues to be rising—various fuels like methanol, ammonia and hydrogen are persevering with their rise, albeit with none having established market dominance as of but. More and more, it’s essential for brand new vessels to be pushed by engines that present choices for emission compliancy over the vessel’s lifetime. Gasoline flexibility and effectivity are the important thing options. On this respect, the 49/60DF distinguishes itself by providing quite a few varied emission paths. It additionally has a degree of effectivity that ensures finest gasoline prices in lots of functions, particularly throughout the cruise, RoPax, RoRo, dredger, and LNG provider segments.

The 49/60DF is on the market 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 mechanically units combustion to optimum ranges.

The engine additionally retains current MAN technolgies such because the gas-injection system, pilot-fuel-oil system and MAN SCR (Selective Catalytic Discount) system.

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 as a consequence of MAN’s new frequent rail system 2.2, whereas the 49/60DF’s methane emissions additionally considerably decreased in fuel mode in comparison with its predecessor. The engine’s benchmark effectivity and fuel-flexible design affords a number of paths to emission compliancy main as much as 2050, as per the present Gasoline EU draft.

MAN Power Options plans to introduce a pure diesel engine based mostly on the 49/60 platform in 2023 that can inherently be retrofit-ready for operating on methanol and LNG ought to the demand come up at a later stage.
