MAN V12X YACHT ENGINE
MAN V12X – THE EXCITING NEW ENGINE
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:
THE NEXT GENERATION OF ENGINES FROM MAN 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.”
NEW POSSIBILITIES AND NEW APPLICATIONS
The MAN V12X yacht engine. A new generation on a completely new basic engine. With the same standards of quality and robustness.
The 30-litre displacement and 2200 hp (1618 kW) of the MAN V12X open up new possibilities in yacht construction.
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.
