The profitable Type Approval Test of the brand new MAN 49/60DF four-stroke was carried out at MAN Energy Solutions headuarters in Augsburg, Germany
MAN Energy Solutions’ MAN 49/60DF engine has acquired its Type Approval after a five-day program on the testbed on the firm’s Augsburg, Germany, headquarters. The Type Approval Test (TAT) of the brand new dual-fuel four-stroke was witnessed by representatives of classification societies ABS, BV, CCS, DNV, LR and RINA who signed the take a look at protocol on profitable completion of the take a look at schedule.
“Today marks the latest milestone in the 49/60DF’s journey since its concept release in 2018,” mentioned Marita Krems, head of four-stroke marine & license, MAN Energy Solutions. “As we enter a new era of decarbonization, the 49/60DF is an obvious choice for vessel owners with ambitious, emission-reduction targets that prize full fuel-flexibility and multiple options for clear emission paths.”
“Over the last eighteen months, we have demonstrated the engine’s reliability and robustness,” mentioned Thomas Huchatz, gross sales supervisor, four-stroke marine, MAN Energy Solutions. “The TAT now issued is a certificate of conformity that confirms that the engine meets the regulatory, technical and safety requirements required to enter the marketplace.”
LATEST DUAL-FUEL MODEL
MAN Energy Solutions introduced the launch of the 49/60DF on the 2022 SMM commerce truthful in Hamburg. The most up-to-date 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 gasoline.
The firm says the brand new dual-fuel four-stroke engine units a benchmark when it comes to four-stroke sector gasoline effectivity – each in gasoline and diesel mode – and thus minimizes gasoline prices and the potential prices for CO2-emission certificates.
The new 49/60DF engine platform options MAN’s newest applied sciences, together with two-stage turbocharging, second-generation common-rail gasoline injection, the SaCoS5000 automation system, and MAN’s next-generation Adaptive Combustion Control ACC 2.0 that mechanically optimizes combustion. The engine additionally retains well-proven MAN applied sciences such because the gas-injection system, pilot-fuel-oil system and MAN SCR (selective catalytic discount) system.
MULTIPLE COMPLIANCY PATHS
The MAN 49/60DF can function and even begin in gasoline mode the place it complies with IMO Tier III with out exhaust gasoline after-treatment. In diesel mode, it complies with Tier III when mixed with MAN’s SCR system.
Soot emissions in diesel mode are halved as a result of second-generation common-rail system 2.2, whereas the 49/60DF’s methane emissions are additionally drastically decreased in gasoline mode. The engine’s benchmark effectivity and fuel-flexible design affords a number of paths to emission compliancy main as much as 2050, as set out within the present Fuel EU draft.
The new engine can also be methanol-ready, that means it’s inherently prepared for retrofit to operating on methanol ought to the demand come up at a later stage. Conversions are easy as all engine variants originate from an preliminary, modular engine design.
PURE DIESEL VERSION
MAN Energy Solutions can also be introducing a pure diesel engine primarily based on the 49/60 platform that shall be methanol- and LNG-ready and options the identical know-how upgrades as its dual-fuel sibling; the engine may function on bio-fuels. This pure-diesel model permits MAN’s new common-rail system to totally play to its strengths of low-emission and low-vibration operation, paired with the utmost flexibilty to design the combusion course of to attenuate gasoline prices. Furthermore, its excessive power-density extends the ability vary of inline engines into functions historically the area of V-type engines.
