MTU marine engine models 12/16V4000M54/M64 are suitable for low-load operation. State-of-the-art
design and equipment features, e.g. TE coolant circuit, sequential turbocharging, jacketed, coolant-
cooled exhaust lines, common rail fuel injection and cylinder cutout allow engine operation at low load.
Nevertheless, low-load operation at engine load below 15% of the nominal rating is permitted for max.
100 hours. In order to avoid inadmissible oil carbon and/or carbon particle deposits in the engine, it is
recommended to carry out a cleaning cycle for at least 20 minutes after extended low-load operation
periods. During the cleaning cycle, engine speed (power) must be increased step by step until all turbo-
chargers are running. The figure shows the basic speed/power run-up procedure for the cleaning cycle
to be carried out.
