Low-load operation

1 Low-load operation
2 Cleaning cycle
3 Cleaning cycle
MTU Series 8V4000M54/M54R marine engines are suitable for low-load operation.
State-of-the-art design and equipment featuring e.g. TE coolant circuit, ETC sequencing, triple-walled water-
cooled exhaust pipes, Common Rail fuel injection and cylinder cutout facilitate this type of operation.
However, low-load operation below 15% of rated engine power is only admissible for max. 100 hours.
We recommend completing a cleaning cycle lasting at least 20 minutes in total following longer periods in
low-load operation to avoid undesirable oil and/or carbon deposits in the engine. The speed (power) must be
increased in stages until all exhaust turbochargers are running in this case.
The figure illustrates the basic procedure for increasing speed/power when performing a cleaning cycle.
