MAN Stage V motoren

MAN Engines is expanding its existing engine portfolio for workboats with the new MAN D3872 engine series. This newly developed V12 engine for commercial applications brings its power from a displacement of 30 liters for the first time. MAN engines have always stood for a low power-to-weight ratio. With the MAN D3872, we offer an even better solution for demanding applications with more power and larger displacement.
The MAN D3872 is based on a completely new basic engine that benefits from the findings of the established MAN D2862 V12 engine series. MAN engines stand for robustness. For this reason, numerous measures have been taken to ensure durability, reliability and future viability for the MAN D3872.”
The new common rail injection system of the MAN D3872, with an injection pressure of an impressive 2,200 bar, enables low fuel consumption and excellent raw emissions. Together with the exhaust gas aftertreatment system, the adapted engine control unit meets current legal requirements such as IMO Tier III and Stage V, Also all current model series from MAN Marine Engines, are approved for HVO.
The compact installation dimensions of the engine (2,235 x 1,250 x 1,320 mm) are almost identical to those of the MAN V12 series with a displacement of 24 litres. Despite its robustness, the MAN D3872, with a weight of 2,720 kg (dry), positions itself as a lightweight among the 12- and 16-cylinder workboat engines in this class. With an outstanding power-to-weight ratio and a small footprint, the MAN D3872 is already proving its future viability. For its future use in combination with the modular exhaust gas aftertreatment system, the MAN D3872 will also be able to be used in confined spaces and at the same time comply with the strict EU Stage V emissions directive.
