MAN Engines
The “X” stands for the neXt generation of engines from MAN Engines with eXtra displacement – 30 litres – and an eXcellent power-to-weight ratio.
The MAN V12X will be the first to join the engine portfolio in the MAN V12X-2200 model. In concrete terms, this means:
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.
“The MAN V12X marks the start of the neXt generation of yacht engines. We are acknowledging this milestone in engine technology with the new name V12X and giving the distinctive engine cover an X design. The redesign of the MAN V12X is accompanied by more displacement for shipyards. As always, we have retained the excellent power-to-weight ratio that MAN engines are known for.”
for optimum separation of the oil withinthe closed crankcase ventilation system.
for optimised coolant supply.
for optimised coolant supply. This ensures the usual long service life of MAN engines.
for optimum cooling of the oil even at high outputs.
for optimised combustion with the usual low specific fuel consumptions typical of MAN.
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.
with increased bearing diameters.
with drill hole increased to 138 mm and stroke increased to 165 mm.
for the transmission of the higher combustion forces.
due to increased displacement and for optimisation of combustion.
flow- and cooling-optimised, so as to be able to handle the high outputs.
for optimum gas exchange even at the highest outputs.
fitted as standard for the first time for marine engines. Regular checking and adjusting of the valve clearance is unnecessary.
The impressively high injection pressure is the basis for the low fuel consumptions and outstanding raw emissions typical of MAN engines.
