  • Page 30: Product Description

    3.5 Product description Description of the diesel engine with exhaust gas aftertreatment Engine The engine is a liquid-cooled four-stroke diesel engine, rotating counterclockwise (seen from driving end), with direct injection, sequential turbocharging and charge-air cooling. The engine is monitored by an engine control and monitoring system (ADEC). Monitoring in the engine room is carried out by the engine control and monitoring unit (LOP).
  • Page 31 • Interface to ECU and EMU • MCS5 dialog interface • Control of an MTU lube-oil priming pump (power components in separate MTU PPC Box) • Connection facility for an MTU Local Operating Station (LOS) The engine interface comprises two parts. The first part is integrated in the engine wiring harness via a Tyco connector X52, 62-pin.
  • Page 32 2 Cleaning cycle 3 ditto MTU marine engines of the Series 4000M53R to …M93L 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.
  • Page 33 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 rec- ommended 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 exhaust turbocharg- ers are running.
