New MAN D3872 Engine Launched as a Powerful, Eco-Friendly Solution for Heavy-Duty Workboats

MAN Engines is expanding its portfolio with the introduction of the new MAN D3872 in the LE427 variant, designed for heavy-duty applications in workboats. This engine boasts an impressive output of 920 kW (1,250 hp) at 1,800 rpm and is equipped with an exhaust gas aftertreatment system that includes a diesel particulate filter and SCR system. By meeting the strict emission standards of the EU Stage V for inland navigation, with limits on nitrogen oxides (NOx), particulate matter (PM), and particle number, this engine is ideal for applications such as push convoys, tugboats, barges, passenger ships, and special vessels.

MAN Engines now offers a comprehensive range of services for inland waterway vessels, including in-line six-cylinder engines and V12 engines with varying displacements and outputs to comply with the strict emission regulations. The company has been working on exhaust gas aftertreatment systems for over a decade to meet the EU Stage V standards, ensuring that the engine, sensors, SCR system, and diesel particulate filter are perfectly matched to maintain emission values in the long term and operate reliably. The heavy-duty variant MAN D3872 LE427 is approved for use with regenerative diesel in Europe and the US.

The MAN D3872 with 1,250 hp (920 kW) at 1,800 rpm is set to be available in EU Stage V from the third quarter of 2025, with plans for other emission stages such as EPA Tier 4, IMO Tier III, and IMO Tier II in 2026. The integration of the exhaust gas aftertreatment system is crucial in coping with the increasing complexity of modern engines and ensuring efficient operation. With thousands of combined diesel particulate filters and SCR catalytic converters already in use across various industries, MAN Engines continues to innovate and provide reliable solutions for heavy-duty applications in the maritime sector.
