6.2
Intelligent combustion control
The intelligent combustion control (ICC) permanently monitors and automatically controls the
combustion process.
The ICC is part of the engine control system (ECS). All ICC modifications of the engine control
parameters obey the IMO regulations and are related to the IMO certificate of the vessel.
The ICC calculates the best engine control parameters for operation, which balances the
compression and firing pressures in the engine (for example injection time offsets and exhaust
valve closing time for each cylinder).
•
This decreases the excessive wear of engine components.
•
This decreases the risk of an engine overload.
•
This prevents manual adjustment failures.
In the ECS you can set to OFF or ON each individual function of the ICC system. When all ICC
functions are set to OFF, the engine operates in a conventional open-loop control mode.
NOTE:
Large differences in the values (for example injection time or exhaust valve operation)
for a cylinder is an indication of possible wear or damage of the cylinder. If necessary,
replace the defective parts.
