2.3 Product description
Description of the engine
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).
Fuel system
Electronically controlled common-rail-injection system with HP pump, pressure accumulator (rail) and single
injectors with integrated individual store.
The electronic control unit controls
• Injection start
• Injection quantity
• Injection pressure
Exhaust system
The exhaust system is equipped with triple-walled, water-cooled exhaust lines.
The triple-walled design offers
• low surface temperature,
• reduced coolant heat,
• absolute gas-tightness.
Turbocharging
Sequential turbocharging with internal, engine-coolant-controlled charge air cooling. The left-hand exhaust
turbocharger is cut-in and cut-out with electronically controlled, hydraulically actuated flaps.
Cooling system
Split-circuit engine cooling system with remote or engine-mounted heat exchanger.
Heating of the charge air in idle and low-load operation prevents white smoke formation.
Seawater only flows through engine coolant and fuel heat exchanger as well as the raw water pump (if appli-
cable)..
Service block
The service components are mounted at the auxiliary PTO end.
The layout permits easy access for maintenance.
Service-components:
• Raw water pump (if applicable), coolant pump
• Fuel filter, switchable
• Automatic oil filter
• Centrifugal lube oil filter
• Coolant expansion tank (only on engines with engine-mounted heat exchanger)
Electronic system
Electronic control and monitoring system with integrated safety and test system with interfaces to Remote
Control System (RCS) and to Monitoring and Control System (MCS).
