2.2 Product description
Description of the engine
Engine
The engine is a liquid-cooled four-stroke diesel engine, rotating counter-clockwise (viewed on driving
end), with direct injection and charge air cooling.
The engine is monitored by an engine control and monitoring system.
The monitoring in the engine room is carried out by the engine control and monitoring unit.
Fuel system
Electronically controlled unit injection pumps with double-walled HP lines.
The electronic control unit controls
• Injection start
• Injection quantity
Fuel leaks are prevented by the following design measures:
1. Special unions on high-pressure fuel lines
2. Double-walled high-pressure fuel lines
The design of the fuel system complies with the SOLAS requirements.
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.
Supercharging
Exhaust turbocharger with charge-air cooling.
Cooling system
Engine cooling as split-circuit cooling system with plate-core heat exchanger.
Seawater only circulates in the engine coolant cooler and raw water pump.
Service block
The service components are mounted at the auxiliary PTO end.
The layout permits easy access for maintenance.
Service components:
• Raw water pump, coolant pump
• Fuel duplex filter, switchable
• Lube oil multiple filter, switchable
• Coolant expansion tank
