MAN launches new DF genset

The new genset was based on the mature MAN 35/44DF CR and MAN 32/44CR engines – well-proven in a multitude of applications over many years with millions of running hours – that form the basis for its operational safety and low maintenance requirements.

The 35/44DF CD comes with a number of features for reducing greenhouse gas emissions, such as methane slip, which it reduces by up to 85% compared with market standards. MAN Energy Solutions states that it expects the first delivery by mid-2024, with the first unit in commercial operation from 2025. 

MAN ES claims that the engine will offer the highest power output in the segment with 560 kW/cylinder. The rating means that fewer cylinders or even engines will be requred for same power output per vessel.

Sephardim Koblenz, Head of Licensing, MAN Energy Solutions, said: “We specifically developed the MAN 35/44DF CD in close collaboration with STX Engine to optimise the requirements of an auxiliary engine. Among other characteristics, both shipyards and shipowners greatly appreciate auxiliary engines that are easily installed and maintained, while reliability and cost-optimisation are also key.”

Alexander Knafl, Head of R&D Engineering, Four-Stroke, MAN Energy Solutions, continued: “A major advantage of the 35/44DF CD, besides its powerful output, is its focus on cutting methane slip and positioning itself as future-fuel ready. This includes being ready for dual-fuel methanol operation by 2026.”

The engine has also been designed with future fuel flexibility in mind. The engine will be available with a range of fuel variants, including biofuels, gas and also future-fuel methanol-ready.
