The MAN 45/60CR will initially be available as 12V and 14V versions that boast power outputs, of 15,600 and 18,200 kW, respectively, with inline versions following at a later stage.
Wayne Jones, MDT’s chief sales office, said: “The new engine combines the best features of the current 48/60CR, such as MAN’s common-rail system with ECOMAP capability, and adds new technologies, such as two-stage turbocharging for an unrivalled specific fuel oil consumption. The resultant reduction in operating expenses and positive environmental impact are sure to attract strong market interest.”
MDT also showed its new high-pressure selective catalytic reduction system - MAN SCR-HP.
This is available for 2-stroke engines of all bore sizes and reduces – through internal catalytic reaction – NOx exhaust emissions to IMO Tier III limits. With specially developed honeycombs and honeycomb materials, as well as an integrated mixing unit, the overall size of the reactor has been drastically reduced, compared to typical market designs and its medium-speed counterpart.
Delivery is first expected from the beginning of 2018.
Bjarne Foldager, MDT’s vice president and head of sales & promotion 2-Stroke Business, said: “The development of our new SCR is an important step on the path to a more sustainable future of shipping and global trade. At the same time it offers additional choices to shipowners worldwide, who can now choose from all NOx reduction technologies and select the optimal solution for their MAN Diesel & Turbo 2-stroke engines.”
Meanwhile, the MAN B&W ME-LGI dual-fuel engine expands MDT’s dual-fuel portfolio, enabling the use of more sustainable, low-flash-point fuels, such as methanol, ethanol, dimethyl-ether (DME) and LPG.
With the designation LGI (liquid gas injection), all existing MAN B&W ME/ME-C/ME-B engines are available for operation on low flashpoint liquid (LFL) fuels. The engines are operated as dual-fuel engines with high-pressure injection. These engines have the same fuel consumption as similar diesel engines, and the same tuning methods can be applied.
