MTU marine engine Series 4000M53R to …M93L may be operated in low-load operation. State-of-the-art de-
sign and equipment features, e.g. TE coolant circuit, sequential turbocharging, jacketed, coolant-cooled ex-
haust 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 recom-
mended to carry out a cleaning cycle for at least 20 minutes after extended low-load operation periods. Dur-
ing the cleaning cycle, engine speed (power) must be increased step by step until all exhaust turbochargers
are running. The figure shows the basic speed/power run-up procedure for the cleaning cycle to be carried
out.
