The M25E engine is based on the very successful M25C engine.
The M25E engine, having a bore of 255 mm and a stroke of 400 mm, is available as generator set with 6,8 and 9 cylinders. The output ranges from 2,100 kW (6M25E) to 3,150 kW (9M25E) at 720 and 750 revolutions per minute.
MaK generator sets are reliable, stable and maintenance friendly, and they have been approved by the main marine classification societies. The generator sets built by MaK use AEM (electric) motors. Of course, other makes can also be used at the customer’s request. Each generator set has a compact structure, so that it can be fitted easily in the engine room.
The MaK generator sets are available in 50 or 60 Hertz configurations. Each set meets the requirements of the most important marine classification societies (such as DNV and Lloyd’s).
MaK supplies an extensive range of propulsion engines (1.020 to 18.000 kW). These are reliable engines with the right capacity for each type of vessel, from small to large. They will do their job under any circumstances, wherever they are in the world.
The engines are supplied including all features. MaK engines can be combined with either a fixed or a controllable-pitch propeller. Bolier offers, in collaboration with Pon Power Nederland, Berg Propulsion propellers. Gearboxes and clutches are added to the standard features on request.
Low Emission Engine (LEE)
From as early as 2000, emission reduction has been an important pillar in MaK’s development strategy. This has been formalised in the Low Emission Engine (LEE). The technologies developed within this concept aim to optimise the combustion process, whereby the emission of NOx, CO2 and soot is drastically reduced.
MaK is also responding to the increased demand for running on LNG. In 2014 the first MaK Dual Fuel engine will be available: the M 46 DF. This engine can run on both gaseous and liquid fuels. It is also possible to convert the existing M 43 C into a Dual Fuel version.
