MAN Engines Launches Powerful V12 Workboat Engine for Medium-Duty Applications

MAN Engines has unveiled its latest workboat engine, the MAN D3872 LE432, boasting a 30-liter displacement. This V12 engine delivers an impressive output of 1,213kW (1,650hp) at 2,100rpm, making it ideal for medium-duty applications like wind farm supply vessels, ferries, passenger ships, and fishing boats. Additionally, power variants of the MAN D3872 with outputs of 1,471 and 1,618kW (2,000 and 2,200hp) at 2,300rpm have already entered production for lighter applications.

The MAN D3872 engine features a new basic design and benefits from enhanced coolant delivery through a new coolant pump and thermostat housing, ensuring longevity. It offers the option of an outer skin cooling system in place of a closed cooling circuit. The redesigned cylinder head optimizes flow and cooling, while improvements in oil supply, including new oil pumps and coolers, have been made. The new common rail injection system, with an injection pressure of 2,200 bar, aims to reduce fuel consumption and emissions.

Looking ahead, MAN Engines plans to further enhance the performance of the MAN D3872 marine engine, catering to heavy-duty applications across various emission levels. Compliant with the latest exhaust gas regulations and suitable for use in the MAN Smart HYBRID Experience, the engine is approved for regenerative diesel use according to European standard EN15940 and US specification ASTM D975. With the addition of the 30-liter MAN D3872 engine, MAN Engines expands its engine range to include in-line six-cylinder, V8, and V12 engines with outputs ranging from 147 to 1,618kW (200 to 2,200hp) and displacements from 12.4 to 29.6 liters.
