A Engine power
B Engine speed
ETC Exhaust turbocharger
MTU marine genset engine Series 4000M23/M33/M43 may be operated in low-load operation. State-of-the-
art design and equipment features e.g. TE coolant circuit, jacketed, coolant-cooled exhaust lines, Common
Rail fuel injection and cylinder cutout allow engine operation at low load.
Low-load operation (engine power up to approx. 20% of rated power) takes place in single-ETC mode (with
only one exhaust turbocharger running). To ensure the functionality of the control mechanism and of the ex-
haust flap of the turbocharger which does not run in low-load operation, it is recommended to operate the
engine with both exhaust turbochargers running after 100 operating hours in low-load operation, at the lat-
est.
