The next generation of engines from MAN Engines
MAN engines are synonymous with robustness. To meet our high standards of durability and reliability, at MAN Engines we have fundamentally revised the next generation of MAN V12X engines.
New possibilities and new applications
- neXt-generation engine
The MAN V12X yacht engine. A new generation on a completely new basic engine. With the same standards of quality and robustness. - eXtra displacement
The 30-litre displacement and 2200 hp (1618 kW) of the MAN V12X open up new possibilities in yacht construction. - eXcellent power-to-weight ratio
The V12X follows MAN Engines’ guiding principle of building compact and powerful engines.
An overview of the main design features
New engine ventilation
for optimum separation of the oil withinthe closed crankcase ventilation system.
New thermostat housing
for optimised coolant supply.
New coolant pump
for optimised coolant supply. This ensures the usual long service life of MAN engines.
New oil cooler
for optimum cooling of the oil even at high outputs.
New camshaft
for optimised combustion with the usual low specific fuel consumptions typical of MAN.
New oil-pump
In addition to fluidic optimisations, new oil pumps and new oil coolers have also been installed, in order to adjust the oil circulation volumes to the high outputs.
New crankshaft
with increased bearing diameters.
Reinforced crankcase
with drill hole increased to 138 mm and stroke increased to 165 mm.
New conrods
for the transmission of the higher combustion forces.
New pistons
due to increased displacement and for optimisation of combustion.
New cylinder heads
flow- and cooling-optimised, so as to be able to handle the high outputs.
New valve train
for optimum gas exchange even at the highest outputs.
Hydraulic valve lash adjuster
fitted as standard for the first time for marine engines. Regular checking and adjusting of the valve clearance is unnecessary.
2200 bar injection system
The impressively high injection pressure is the basis for the low fuel consumptions and outstanding raw emissions typical of MAN engines.
