2.2 Product description
Description of the engine
Engine
The engine is a liquid-cooled, four-stroke cycle diesel engine, rotating counter-clockwise (seen from driving
end), with direct injection, sequential turbocharging and charge-air cooling.
The engine is monitored by an engine control and monitoring system.
Monitoring in the engine room is carried out by the engine control and monitoring unit.
Fuel system
Electronically controlled unit injection pumps with jacketed HP lines.
The electronic control unit controls
• Beginning of injection
• Injection quantity
Exhaust system
The exhaust system is equipped with triple-walled, water-cooled exhaust lines.
The triple-walled design permits
• Low surface temperature
• Reduced amount of heat to be dissipated by the coolant
• Absolute gas-tightness
Turbocharging
Sequential turbocharging with charge-air cooling (turbochargers can be cut in/out during operation).
Cooling system
Engine cooled by split-circuit cooling system with plate-core heat exchanger.
Service block
The service components are mounted at the auxiliary PTO end.
The arrangement facilitates easy access for maintenance operations.
Service components:
• Raw water pump, coolant pump
• Fuel duplex filter, switchable
• Lube-oil multiple filter, switchable
• Centrifugal lube oil filter
• Coolant expansion tank
Electronic system
Electronic control and monitoring system with integrated safety and test system, providing interfaces to Re-
mote Control System (RCS) and Monitoring and Control System (MCS).
Electronic Engine Control Unit (ECU)
Functions:
• Engine speed control with fuel and speed limitation dependent on engine state and operating conditions;
• Control of sequential turbocharging;
• Data processing logistics for analog and binary signals;
• Interface for data transfer to CAN field bus for remote control and ship-side monitoring;
• RS 232 interface for connection of MTU dialog unit.
