Sets standards in engine classTierIITierIIISCR

Engine output is limited to 100% of rated output for engines driving a propeller. Output of engines driving a generator it limited to 110% of rated output. Overload above 100%  is permitted only briefly to prevent frequency drop during sudden load application. Our MAN 48/60B engine can run on heavy fuel oil with a viscosity up to 700 mm²/s (cSt) at 50° C. Continuous operation on heavy fuel oil is permitted in an output range of 20% to 100%. It can even be operated below 20% for brief periods.
