MAN unveils workboat engine at SMM

MAN says its V12 engine, which has power variants of the MAN D3872 (1,471 and 1,618 kW or 2,000 and 2,200 hp at 2,300rpm) , is suitable for wind farm supply vessels, ferries, passenger ships and fishing boats.

“The new V12 engine benefits from improved coolant delivery through a new coolant pump and thermostat housing, which contribute to the engine’s longevity,” MAN says.

“As an alternative, the engine is available with an outer skin cooling system instead of a closed cooling circuit. The distinctive cylinder head of the MAN D3872 has also been re-designed to optimise flow and cooling. In addition, the oil supply was adjusted by using flow-optimizing measures in addition to new oil pumps and new oil coolers.

“The new common rail injection system is another important step for this next generation of engines: with an impressive injection pressure of 2,200 bar, the basis is laid for achieving low fuel consumption and excellent raw emissions.”

MAN says the new engine complies with exhaust gas regulations and has been technically designed to use as a hybrid.

“With the new 30-litre MAN D3872 engine, MAN Engines is significantly expanding its engine portfolio in terms of output and displacement,” says the company. “This means that in-line six-cylinder, V8 and V12 engines from 147 to 1,618kW (200 to 2,200hp) with a displacement of 12.4 to 29.6 litres are currently available for light, medium and heavy-duty applications.
